jquery implements display of selected users_jquery

Selecting users is a commonly used function, which mainly includes 2 function points (save selected options, display selected users)

Feature Requests:

1 Select the user interface to be displayed as a pop-up box

2 Dynamic loading of page options (department and user)

3 Selected users will be displayed with a check mark

Implementation analysis:

First of all, because the window is a pop-up box, the content of the page is mainly obtained asynchronously. Because the content is divided into two parts (1 to be selected and 2 to be selected), there are two processing methods.

Method 1: The background generates a complete html code based on the data (1 to be selected, 2 selected items), and returns it through an asynchronous operation

Method 2: The waiting items and selected items are obtained through two asynchronous methods, and then the effect is selected in the page js matter.

Because I don’t like writing a lot of logic on the page, I prefer the first option and recommend it.

Page

1 A dialog box for selecting shared files will pop up
Logic: 1 Call the showShareRange method asynchronously to obtain the complete html code.

//弹出选择共享文件的对话框 
  function showShareFile(){
    disableFileArea();
    if(!chooseObj.isChoosed()){
      handleWarm("请先选择文件或者目录");
      enableFileArea();
      return;
    } 
    $('#shareRange').html('');
    showflowcontent('fxcontentflow');
    $.ajax({
      url : '../share/showShareRange.do',
      //url:'${ctx}/index.jsp',
      cache : false,
      type : 'post',
      dataType : 'html',
      async : true,
      contentType : "application/x-www-form-urlencoded;charset=utf-8",
      data : {
        'signid' :chooseObj.id,
        'objtype' :chooseObj.type
      },
      success : function(html) {
        $('#shareRange').html(html);
         
      }
    })
   }

2 Pop-up box interface code

<div class="flowcontent" id="fxcontentflow"> 
 <div id="fxloadfile" class="content"> 
  <div class="title"><strong>分享文件</strong><input type="button" class="closebtn gb" onClick="hideflowcontent(this)" title="关闭" /><input type="button" class="hidebtn" /></div> 
  <div class="body"> 
   <div class="file" id='shareRange'><!-- 共享范围 --> 
   </div><!-- file --> 
   <div class="btns"><input type="button" class="submitbtn" value="" onClick="shareFile()" /><input type="button" class="cancelbtn gb" onClick="closeflowcontent('fxcontentflow')" /></div> 
   <div class="h30"></div> 
  </div> 
 </div> 
</div>
