Recent queries involving Treegrid components require dynamic load query results for dynamically updating Easyui Treegrid components based on query criteria search through Treegrid source code and document Discovery Treegrid is extended from the DataGrid and tree, But in the past, using the Reload method of the DataGrid to load the query results data, but Treegrid only execute reload can not load the query results with parameters, may be a limitation, the following code can not load the query results:

Copy the Code code as follows:
<table id= ' Treegrid ' class= ' easyui-treegrid ' url= '/user/list ' ></table>
$ (' #treegrid '). Treegrid (' reload ', {' name ': ' Mikel '});

Then went to the official forum search related issues, found a valuable post, enlightened, why to expect the Treegrid component to query data asynchronously, why not first asynchronous, and then load the returned JSON data? The code is as follows:

Copy the Code code as follows:

function LoadData ()
{
$.post ('/user/list ', {name: ' Mikel '},function (data) {
$ (' #treegrid '). Treegrid (' LoadData ',data);
}, ' json ');
}
