Jquery implements saving selected users, while jquery implements users

Jquery implements saving selected users, while jquery implements users

1 Introduction

Functional requirements:

1. Select the user interface and display it in a pop-up box.

2. Dynamic Loading of page options (department and user)

3. Save the selected user

Implementation Analysis:

Save the selected user logic:

Delete the previously selected user record list (equivalent to clearing)
Add a list of newly selected user records
Page

1. Save shared files

// Save the shared file function using file () {// parameter var signid = chooseObj. id; var objtype = chooseObj. type; var userlist = ""; $ ("input [name = Your userid]"). each (function () {// this is the checkbox object in the html. So through // this. if ($ (this ). attr ('checked') {userlist = userlist + $ (this ). val () + ","}); if (userlist. length> 0) {userlist = userlist. substring (0, userlist. length-1)} $. ajax ({url :'.. /share/upload file. do ', // url:' $ {ctx}/index. jsp ', cache: false, type: 'post', ype: 'html', async: false, contentType: "application/x-www-form-urlencoded; charset = UTF-8 ", data: {'signid': signid, 'objtype': objtype, 'userlist': userlist}, success: function (ret) {// Exception Handling if (ret = 3) {handleWarm ("the target folder is your own"); return;} else if (ret = 2) {handleWarm ("sub-directories cannot be moved"); return ;}// closeflowcontent ('fxcontentflow'); refreshThisContent ();}})}

Html reference of page option content (for reference only, no need to implement)

<Div class = "fxtitle"> school leader </div> <ul class = "fxxz"> <li> <input type = "checkbox" name = "shareUserId" value = "xiaolin "> Xiao Lin </li> <input type =" checkbox "name =" shareUserId "value =" wangshuotong "> Wang Shuo </li> <input type = "checkbox" name = "shareUserId" value = "wangshengyang"> Wang shengyang </li> <input type = "checkbox" name = "shareUserId" value = "qifeng "> Qi Feng </li> <input type =" checkbox "name =" shareUserId "value =" tangyiwen "> Tang Yiwen </li> <input type = "checkbox" name = "shareUserId" value = "zhanglisheng"> Zhang Lisheng </li> <input type = "checkbox" name = "shareUserId" value = "zhengshao "> Zheng </li> </ul> <div class =" fxtitle "> Office </div> <ul class =" fxxz "> <li> <input type = "checkbox" name = "shareUserId" value = "lujianping"> Lu Jianping </li> <input type = "checkbox" checked = "true" name = "shareUserId" value = "guoshunlan"> Guo shunlan </li> <input type = "checkbox" name = "shareUserId" value = "fangying"> Fang Ying </li> <li> <input type = "checkbox" name = "shareUserId" value = "jiaoxiaojun"> Jiao Xiaojun </li> <input type = "checkbox" checked = "true" name = "Your userid" value = "songweilei"> song weilei </li> <input type = "checkbox" name = "Your userid" value = "zhangxinmin"> Zhang Xinmin </li> <input type = "checkbox" checked = "true" name = "shareUserId" value = "lijing"> li Jing </li> <input type = "checkbox" name = "shareUserId" value = "wangkaiyu"> Wang Kaiyu </li> </ul>

Controller Layer

Service Layer

/*** Specify shared files and folders ** @ param signid folder id/file id * @ param objtype operation object type (1: file, 2: folder) * @ param userlist shared user range * @ return 0 indicates operation failed/1 indicates operation succeeded **/public int shareFile (String signid, String objtype, String userlist, String sharer) {// Delete the shared record fileShareDao. deleteFileshare (signid, objtype); // create a shared record String users [] = userlist. split (","); // save each shared user for (int I = 0; I <users. length &&!

If there is an App. class
Enter
