First put the final rendering:

Jquery EasyUI实现treegrid上显示checkbox并取选定值的方法

Then the code:

html file:

<body>
<h1>TreeGrid</h1>
<div>
<a id="consle" href="#">consle</a>
</div>
<table id="test" title="Folder Browser" style="width:400px;height:300px" > 
</table> 
</body>

Description: Nothing , title, and then a table. I put a button consle for some testing. You don’t need to delete it. Of course, you need to reference several js files and css files:

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<meta name="keywords" content="jquery,ui,easy,easyui,web">
<meta name="description" content="easyui help you build your web page easily!">
<title>jQuery EasyUI Demo</title>
<link rel="stylesheet" type="text/css" href="http://www.jeasyui.com/easyui/themes/default/easyui.css">
<link rel="stylesheet" type="text/css" href="http://www.jeasyui.com/easyui/themes/icon.css">
<script type="text/javascript" src="http://code.jquery.com/jquery-1.6.1.min.js"></script>
<script type="text/javascript" src="http://www.jeasyui.com/easyui/jquery.easyui.min.js"></script>
<script type="text/javascript" src="ws.js"></script>

Then the js file:

$(function(){
$(&#39;#test&#39;).treegrid({ 
url:"data/treegrid_data.json", 
idField:&#39;id&#39;, 
treeField:&#39;name&#39;, 
animate:"true",
rownumbers:"true",
columns:[[ 
{title:&#39;Task Name&#39;,field:&#39;name&#39;,formatter:function(value,rowData,rowIndex){
return " " + rowData.name;
},width:180}, 
{field:&#39;size&#39;,title:&#39;Persons&#39;,width:60,align:&#39;right&#39;}, 
{field:&#39;date&#39;,title:&#39;Begin Date&#39;,width:80}
]] 
});
$("#consle").bind("click",consleclick)
});
function set_power_status(){ 
var idList = ""; 
$("input:checked").each(function(){
var id = $(this).attr("id");
if(id.indexOf("ceshi_")>-1)
idList += id.replace("ceshi_",&#39;&#39;)+&#39;,&#39;;
})
alert(idList);
}
function consleclick(){
var node = $(&#39;#test&#39;).treegrid(&#39;expandAll&#39;,2);
}

Description: The treegrid of easyUI is called. In order to display the checkbox, a formatter is made on the first column. In order to display the effect, the event of getting the selected checkbox is bound. You can remove it if it is not needed. You can also remove the alert and change it to something else. event handling function.
