Jquery saves selected user _ jquery

This article describes how to save selected users by using jquery. For more information, see section 1.

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)
