Abstract
The present invention relates to the technical field of Java-based Web development, and in particular relates to a universal method for uploading files in JSP. According to the present invention, an upload plugin jQuery Uploadify is encapsulated such that the plugin is called where necessary, thereby implementing the file uploading function in JSP. The method supports concurrent uploading of a plurality of files, with a progress bar but no refresh display, and in addition, the upload speed is high. The method according to the present invention can be widely applicable to the technical field of Java-based Web development.
Description
Technical field
The present invention relates to Java language Web development technique field, be specifically related to a kind of method of general jsp upload file.
Background technology
Current website or system often can use files passe and user carries out alternately.Traditional files passe is uploaded by form list, and the distinct disadvantage of this method is exactly to upload a file at every turn, will operate repeatedly if will upload multiple file, upload progress is not had to show, and want refresh page, so very inconvenient, user experience is very poor.
Summary of the invention
The technical matters that the present invention solves is a kind of method providing general jsp upload file; Promote convenience and Consumer's Experience.
The technical scheme that the present invention solves the problem is:
Described method uploads plug-in unit Uploadify to JQuery to encapsulate, and the place being provided with files passe is called, and realizes the files passe function of jsp; Described method supports that multifile is uploaded simultaneously, and band progress bar is without refreshing display and uploading speed is fast.
Described method mainly comprises the following steps:
1st step, write the unified jsp template page uploadify.jsp for uploading;
2nd step, in template page uploadify.jsp, introduce the associated class library file of Uploadify plug-in unit: jquery-1.4.2.min.js, jquery.uploadify.v2.1.4.js, swfobject.js etc.;
3rd step, submission path, file directory, type, size to the upload file of Uploadify plug-in unit, whether support multiple document uploading, the correlation parameters such as quantity can be uploaded at every turn and modify;
4th step, encapsulation unified call interface, be put into template page uploadify.jsp in an Iframe, rewrite simultaneously to the correlation parameter of Uploadify plug-in unit;
5th step, write and receive the backstage java program of files passe file is preserved;
6th step, upload complete, destory is carried out with releasing memory to control.
The invention has the beneficial effects as follows: the files passe function being realized jsp by the encapsulation of JQuery being uploaded to plug-in unit Uploadify to have and support that multifile is uploaded simultaneously, band progress bar is without refreshing display and the advantage such as uploading speed is fast.Efficiently solve the drawback that traditional files passe mode is brought, be widely used in Java language Web development technique field.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described:
Fig. 1 is process flow diagram of the present invention.
Embodiment
As shown in Figure 1, the present invention realizes the files passe function of jsp by the encapsulation of JQuery being uploaded to plug-in unit Uploadify;
Concrete steps are as follows:
1st step, write the unified jsp template page uploadify.jsp for uploading;
2nd step, in template page uploadify.jsp, introduce the associated class library file of Uploadify plug-in unit: jquery-1.4.2.min.js, jquery.uploadify.v2.1.4.js, swfobject.js etc.;
3rd step, the correlation parameter of Uploadify plug-in unit to be modified, such as: submission path, file directory, type, the size of upload file, whether support multiple document uploading, can quantity etc. be uploaded at every turn
4th step, encapsulation unified call interface, be put into template page uploadify.jsp in an Iframe, rewrite simultaneously to the correlation parameter of Uploadify plug-in unit
5th step, write and receive the backstage java program of files passe file is preserved;
6th step, upload complete, destory is carried out with releasing memory to control.
Claims (2)
