jQuery implements the method of setting focus in dialog_jquery

The example in this article describes how jQuery implements dialog setting focus. Share it with everyone for your reference. The specific analysis is as follows:

When a dialog box pops up, by default we should focus on the input text box, but writing $("#txtGroupName").focus(); before dialog.show() will not take effect.

After checking the official documentation of jQuery, I found that dialog provides a focus parameter, ok, try it first~~

//显示新建项目群组对话框 
function showCreateProjectGroupDialog(i) { 
  $("#layout-createProjectGroup-pane").show().dialog({ 
    modal: true 
    , title: lmslang.listProjectGroup_Create 
    , width: 450 
    , overlay: { 
      opacity: 0.5 
    } 
    , focus: function(ev, data) { 
      $("#txtGroupName").focus(); 
    } 
    , buttons: { 
      "保存": function() { 
        var name = el("txtGroupName").value; 
        var description = el("txtDescription").value; 
        var b = $("#fgroup").valid(); 
        if (b) { 
          createGroupJson(); 
          closeCreateGroupDialog(); 
        } else { 
          showError(lmslang.formValidate_Error); 
        } 
      } 
      , "取消": function() { 
        closeCreateGroupDialog(); 
      } 
    } 
  }); 
} 
//隐藏新建项目群组对话框 
function closeCreateGroupDialog(){ 
  $("#layout-createProjectGroup-pane").dialog("close"); 
} 

Done! O(∩_∩)O..

I hope this article will be helpful to everyone’s jQuery programming.
