mytree.setImagePath("<%=appName%>/tpc/dhtmlx/dhtmlxTree/codebase/imgs/");



mytree.enableTreeLines(false);



//mytree.enableTreeImages(true);



//mytree.enableTextSigns(“true”);



mytree.enableHighlighting(true);



mytree.showItemSign(“treebox”,true);


mytree.setIconSize(12,12);



mytree.setOnClickHandler(openUnits);


mytree.setOnOpenHandler(edit4TreeGrid);



mytree.insertNewChild(‘0’,‘1^<%=TGlobalServlet.topUnitId%>’,’<%=TGlobalServlet.topUnitId%>’, 0,0,0,0,“TOP,CHILD”);



mytree.setUserData(‘1^<%=TGlobalServlet.topUnitId%>’,“ORG_LEVEL”,1);


mytree.openAllItems();



hideLoadingMsg();



</script>



======================================



 



function edit4TreeGrid(unitId,open)



{



      if(open==0){



      parForTree= unitId;



      var parUnit = unitId.split(’^’);



       var orgLevel = mytree.getUserData(unitId,“ORG_LEVEL”)



      HRService.getUnitsDetails(<%=ownerId%>,’<%=clientId%>’,parUnit[1],orgLevel,callBackTree);



     }



    else



   {



     return true;



    }

=============================================



function callBackTree(data)



{



for(var i=0; i<data.length;i++)



{



var dataArr = data[i];







mytree.insertNewChild(parForTree,dataArr[4]+"^"+dataArr[0],dataArr[1],0,0,0,0,“TOP,CHILD”);



mytree.setUserData(dataArr[4]+"^"+dataArr[0],“ORG_LEVEL”,dataArr[4]);


}

Hello,


the provided code demonstrates the following behavior: there is one node initially. But when you click on it - child nodes must be loaded.


There is a special functionality in tree - dynamic loading. So, you don’t need to set own event handlers in this case. Moreover “child” attribute, that shows + sign for items without child nodes, works only with dynamic loading. So, you should use dynamic loading in any case.


Just include the following code instead of mytree.setOnOpenHandler(edit4TreeGrid);


mytree.setXMLAutoLoading(edit4TreeGrid);


mytree.setXMLAutoLoadingBehaviour(“function”);


function edit4TreeGrid(unitId){


/your code here/


}
