Hi ,

I am use the v4.5. I have a problem of ajax. It can not pass the values to other page.
Please Help with me. thank you very much.

main page:

userSecurityFormDataB.attachEvent("onChange", function(name,value,is_checked){
    	myLayout.cells("c").expand();
    	myTree = myLayout.cells("c").attachTree();
    	myTree.setImagePath("dht/skins/web/imgs/dhxtree_web/");
    	myTree.enableCheckBoxes(1);
	myTree.enableThreeStateCheckboxes(true);
    	
    	if(name=="customerRelationshipManagement"){
    		myTree.load("php/menuTree.php?itemName=customerRelationshipManagement");
    		getSubString();
    	}

function getSubString(){
	
	myTree.attachEvent("onCheck", function(id, state){
	    
	dhtmxAjax.get("php/menuTreeConnector.php?username=test&itemId=competitor");
	   
	        			
	});
}

menuTreeConnector.php

<?php

//include db connection settings
require_once("config/config.php");


	$res=mysql_connect($mysql_server,$mysql_user,$mysql_pass);
	mysql_select_db($mysql_db);

	$itemId=$_GET['itemId'];
	$userName=$_GET['username'];
?>

Hi,

please use dhx4.ajax instead of dhtmlxAjax:

dhx4.ajax.get(“php/menuTreeConnector.php?username=test&itemId=competitor”)
