jquery Implementation saves selected users _jquery

1 Introduction

Functional Requirements:

1 Select the user interface to display in a pop-up box

2 page Options dynamic loading (departments and users)

3 Save the Checked users

Implementation analysis:

Save selected user logic:

Deletes the list of user records that were originally selected (equivalent to empty operation)
Add a list of newly selected user records
Page

1 Save shared files

Save shared file function Sharefile () {//parameter var Signid = chooseobj.id;
    var objtype = Chooseobj.type;
    var userlist = ""; $ ("Input[name=shareuserid]"). each (function () {//This is the checkbox object in that HTML. So the direct Access property via//This.checked is possible if ($ (this). attr (' checked ')) {userlist = userlist+$ (This). Val () + ",
    "
       }
    }); if (userlist.length>0) {userlist = userlist.substring (0, Userlist.length-1)} $.ajax ({url: ' ...
      /share/sharefile.do ',//url: ' ${ctx}/index.jsp ', Cache:false, type: ' Post ', DataType: ' HTML ',  Async:false, ContentType: "Application/x-www-form-urlencoded;charset=utf-8", data: {' Signid ' : Signid, ' objtype ': objtype, ' userlist ': userlist}, Success:function (ret) {//exception 
          Process if (ret==3) {handlewarm ("Destination folder is own");
        Return 
        }else if (ret==2) {handlewarm ("Cannot move to subdirectory");  Return
        }//Closeflowcontent (' Fxcontentflow ');
      Refreshthiscontent ();

 }
    })
  }
