S101：Configuration baseline field drop-down list.
Skilled in the art realises that, a cron expression formula has at least six (may also be 7) to have the field of space-separated
(time element).
For example, time element is followed successively by order：
Second (0~59)；
Divide (0~59)；
When (0~23)；
My god (moon) (0~31, it is necessary to consider the number of days of the moon)；
All (what day) (1~7：SUN, MON, TUE, WED, THU, FRI, SAT)；
The moon (0~11)；
Year (such as 1970-2099).
In the present invention, any of the above time elements can serve as benchmark field, therefore, pulls down and arranges in benchmark field
In table configuration, each above-mentioned time element is configured to the respective option of drop-down list.
In the specific implementation, JavaScript drop down list controls can be based on, the configuration of benchmark field drop-down list is realized.
A kind of literal translation formula scripts of JavaScript, are a kind of regime type, weak type, the language based on prototype, interior

Plus dynamic function.
JavaScript is widely used in webpage design and special effect of web making etc..Almost all of webpage can all be used
JavaScript, such as form validation, animation, style sheet control etc..In the exploitation of webpage, built-in many bases
The control of plinth, such as input frame, drop-down list, check box etc., and the control on a little bases also provides some events machine
System can allow JavaScript to make corresponding response.Therefore, the present invention can be developed very rich based on these events
Rich function, meanwhile, some error-prone text entry operations can be simplified to the selection operation at interface, in all its bearings
The demand of user is met to extend these basic controls.
S102：The trigger event of benchmark field drop-down list is monitored, currently selected fixed benchmark field is determined.
For example, the onchange events by monitoring benchmark field drop-down list, when the option of benchmark field drop-down list
When changing, it may be determined that go out the benchmark field currently selected by user.Wherein, onchange events are to change defeated in client
Enter the value of control, such as one textbox can trigger this event, that is, onchange is triggered when element value changes.
S103：Corresponding relation based on the benchmark field pre-set with cron expression formula forms, determines the currently quilt
The corresponding cron expression formulas form of selected reference field.
In present invention, it is desirable to the benchmark field pre-set and the corresponding relation of cron expression formula forms, were specifically set
Journey includes：Based on each benchmark field, the corresponding all subordinate's fields of each benchmark field are determined；For each subordinate's word
Section, the drop-down list of configuration subordinate field, so as to complete the setting of the cron expression formula forms corresponding to each benchmark field.
Still using the above-mentioned second, point, when, day, week, the moon, year time element as field, for example, on the basis of selected " year "
Field, then subordinate's field in " year " includes：" second, point, when, day, week, the moon "；If field on the basis of selected " moon ", then
Subordinate's field of " moon " includes：" second, point, when, day, week "；If field on the basis of selected " week ", then subordinate's field in " week "
Including：" second, point, when, day "；If it is selected " my god " on the basis of field, then " my god " subordinate's field include：" second, point, when "；
If it is selected " when " on the basis of field, then " when " subordinate's field include：" second, point "；If field on the basis of selected " dividing ",
The subordinate's field so " divided " includes：" second "；If field on the basis of selected " second ", because the second has been minimum tempon
Element, thus the second there is no subordinate's field.
Determine after each corresponding subordinate's field of each benchmark field, it is necessary to configure the drop-down row of each subordinate's field
Table, so as to complete the setting of the cron expression formula forms corresponding to each benchmark field.The drop-down row of concrete configuration subordinate field
The mode of table, can still be realized based on JavaScript drop down list controls as previously described.
S104：The value of the drop-down list of each field in cron expression formula forms determined by obtaining, generation cron expression
Formula.
In one implementation, the value of the drop-down list of each field in cron expression formula forms determined by obtaining,
Cron expression formulas are generated, including：To the onchange things of the drop-down list of each field in identified cron expression formulas form
Part is monitored, when monitoring onchange events, is called and is stated cron expression formula generating functions, gets generation onchange
The value of the drop-down list of the field of event；According to the value of the drop-down list of each field, cron expression formulas are generated.
Further, according to the value of the drop-down list of each field, cron expression formulas are generated, including：For identified institute
Each field in cron expression formula forms is stated, an empty array of field number correspondence size is set up；Based on benchmark field and
Occur the value of each field of onchange events, update the value of array；Array is spliced into character string, cron expression is obtained
Formula.
Wherein, by the onchange events for the drop-down list for monitoring each field, each subordinate's field can be learnt
The value of option changes.Then again by way of above-mentioned array assignment, you can obtain each field (benchmark field and each
Individual subordinate's field) option value, so as to ultimately generate cron expression formulas.
Below with a specific example, the implementation method to the plan target described in Fig. 1 carries out exemplary description.
In the example, in task dispatching platform website for task configure cron expression formulas, comprise the following steps (1)-
(3)。
(1) represent that task triggers date reference field using a drop-down list
For example, it is necessary to configure a cron expression formula for task in the configuration of timed task, the task can be " every
Year ", " monthly ", " weekly ", " daily ", " per hour ", " per minute ", " each second " triggering.Here a drop-down row are accomplished by
Table represents the benchmark field of task triggering, and example code is as follows：
Value therein represents the id of benchmark field, subsequently can the root root benchmark field show other fields correspondence
Drop-down list.
(2) the benchmark field triggered by task shows other fields
For example, because seven fields of cron expression formulas are corresponded to respectively：Second, point, when, day, week, month, year, therefore, configuration
Following " benchmark field-subordinate's field " display rule：
If the selection of benchmark field is " year "：So expression formula form is：_ _ _ _ month
If the selection of benchmark field is " moon "：So expression formula form is：_ _ _ date *
If the selection of benchmark field is " week "：So expression formula form is：___* what day
If benchmark field selection for " my god "：So expression formula form is：___**
If benchmark field selection for " when "：So expression formula form is：__***
If the selection of benchmark field is " dividing "：So expression formula form is：_****
If the selection of benchmark field is " second "：So expression formula form is：*****
Wherein, above-mentioned expression formula form for " second, point, when, day, week, month, year ", the value of " _ " representatives " second, divide or when ",
" * " represent any value can, "" represent to ignore.
Pass through rule as above, when selecting different benchmark fields, the corresponding drop-down of field that other needs are shown
List display comes out.
In order to realize the display of other subordinate's fields, it is necessary to be pre-configured with the drop-down list of each subordinate's field.For example, right
In each field of each cron expression formulas, it is mapped therewith with a drop-down list.Code sample is as follows：
Complete " benchmark field-subordinate's field " rule configuration and each subordinate's field drop-down list configuration it
Afterwards, it is possible to realize the display of other field drop-down lists by monitoring the option change events of benchmark field drop-down list.
For example, the onchange events of benchmark drop-down list are monitored, when the option of benchmark drop-down list changes
Wait, just readjustment this function of baseChage：
$("#base").on('change',baseChage)；
Accordingly, it would be desirable to define in event call-back method baseChage, this method, need are shown according to benchmark field id
The drop-down list to be shown.Code sample is as follows.
First all field drop-down lists are stashed first, code is as follows
$("#month").hide()；
Other fields are similar.
Secondly, rule in previous step (2) shows corresponding drop-down list：
// choosing is annual, then shows monthly
If (baseId==7)
$("#month").show()；
}；
The same logic of the drop-down lists of other fields.
So far：The display of the corresponding drop-down list of each field is achieved that by the step.It can be seen that, the present invention can be with
Effectively control which field to need display, which field need not be shown, so as to reduce unnecessary operation, also cause boundary
Face is succinct.
(3) cron expression formulas are generated by the value of each drop-down list
An onchange event is bound for the corresponding drop-down list of each field, when being triggered onchange events,
The function of a cron expression formulas generation is just called, code sample is as follows：
(3.1) onchange events are bound for each drop-down list：
$("#month").on('change',gegerateCron)；
$("#weekDay").on('change',gegerateCron)；
$("#day").on('change',gegerateCron)；
$("#hour").on('change',gegerateCron)；
$("#minute").on('change',gegerateCron)；
$("#second").on('change',gegerateCron)；
(3.2) when the drop-down list of corresponding field changes, the function bound before will be triggered
GegerateCron, code is as follows：
First, being received within each field in an array, the content of corresponding field is subsequently replaced again.
For example, var cron=[' * ', ' * ', ' * ', ' * ', ' * ', '']；Respectively correspond to the second, point, when, day, the moon, week.
Using benchmark field and subordinate's field as below step Rule of judgment.
Var baseId=$ (' #base') .val ()；
Var name=$ (this) .attr (" id ")；
Then, according to benchmark field and subordinate's field of generation trigger event, by the array of the correspondence position in step a
Value is replaced, and code snippet is as follows：
The replacement of other corresponding fields and similar to the above.
Finally, then by array be spliced into a character string, you can with arrive required cron expression formulas, return
cron.join("")；
So far：Final cron expression formulas are just obtained.
It is an exemplary cron expression formula view with reference to Fig. 2, wherein, benchmark field is the moon, occurs trigger event
Subordinate's field be day, when and point, by way of above-mentioned acquisition each field value, finally show cron expression as shown in Figure 2
Formula view.It can be seen that, in Fig. 2, the set of time of timed task is：The 1st day monthly 6 when 5 points.
It can be seen that, the present invention is manually entered each field in the implementation method of above-mentioned plan target for prior art
The mode of value is improved, by way of drop-down list, and user only needs to carry out simple selection to the option of each field,
Due to not needing user's input, so as to avoid user's input error, error rate is thus reduced；Further, since only showing selected base
Quasi- field is corresponding and has subordinate's field of trigger event, when therefore, it can more directly perceived, succinct displaying timed task triggering
Between view；Moreover, the present invention can be realized by JavaScript scripts, therefore, it is possible to very easily with some existing frameworks
Integrated.

During triggering, the function of a cron expression formulas generation is just called, code sample is as follows：
(3.1) field drop-down list and the check box of each subordinate's field binding onchange events on the basis of：
$("#month").on('change',gegerateCron)；
$("#weekDay").on('change',gegerateCron)；
$("#day").on('change',gegerateCron)；
$("#hour").on('change',gegerateCron)；
$("#minute").on('change',gegerateCron)；
$("#second").on('change',gegerateCron)；
(3.2) when the drop-down list or check box of corresponding field change, the function bound before will be triggered
GegerateCron, code is as follows：
First, being received within each field in an array, the content of corresponding field is subsequently replaced again.
For example, var cron=[' * ', ' * ', ' * ', ' * ', ' * ', '']；Respectively correspond to the second, point, when, day, the moon, week
Using benchmark field and subordinate's field as below step Rule of judgment.
Var baseId=$ (' #base') .val ()；
Var name=$ (this) .attr (" id ")；
Then, according to benchmark field and subordinate's field of generation trigger event, by the array of the correspondence position in step a
Value is replaced, and code snippet is as follows：
