问题
I'm in the AngularJS environment, and trying to get a jqWidgets TreeGrid working.
I have the dataAdapter all wired up with the Json formatted data, however the grid renders empty data but shows columns (see attached image).
I'm using this non Angular-based demo as a guide to wire up the dataAdapter:
http://www.jqwidgets.com/jquery-widgets-demo/demos/jqxtreegrid/index.htm#demos/jqxtreegrid/javascript-tree-grid-binding-to-json.htm
because this Angular sample is too simple (i.e. doesn't use the dataAdapter object) -
http://www.jqwidgets.com/jquery-widgets-documentation/documentation/angularjs/angularjs.htm
Here's the html snippet:
<div class="widget-content user">
<jqx-treegrid jqx-instance="jqGridHierObj" jqx-settings="vm.jqGridHierSettings">
</jqx-treegrid>
</div>
Here's what my treegrid settings look like, complete with data and model.
It appears that JQ is injecting the additional "_source" property because I'm certainly not. There also an extra "localdata" property. ex/ I've added the "localData" property:

and in my controller code, the grid function :
function initHierarchyGrid_Generic(reportType, isHierarchy, isDynamic) {
isDynamic = (isDynamic == undefined ? false : isDynamic);
if (isDynamic) {
// in this case we have saved everything to $rootScope
myModel = $rootScope.reptWizard.modelDef;
myColumns = $rootScope.reptWizard.colDefs;
myData = $rootScope.reptWizard.aggrResults;
}
// add Json data onto myModel object; define jqWidgets data adapter
myModel["localData"] = myData;
var dataAdapter = new $.jqx.dataAdapter(myModel);
var ds = {
schema: {
model: myModel
},
pageSize: 10,
data: dataAdapter
};
$scope.jqGridHierObj = {}; // object reference
vm.jqGridHierSettings = { // jqwidgets grid
altrows: true,
width: 600,
height: 300,
source: myData,
columns: myColumns
};
return vm.jqGridHierSettings;
}
* UPDATE *
I seems like my dataAdapter definition is causing the localData data array to be nested in their object. Here's where I found localData in f12 console tools. It must be wrong :
* UPDATE 2 * Trying to get a jsfiddle working, but having a bit of trouble :
http://jsfiddle.net/L9530s43/2/
vm.jqGridHierSettings.source._source.source._source.localData
回答1:
May be the problem is that you do not use dataAdapter, too. The settings object's source property points to myData, not to dataAdapter
