$(".updateSupplyBtn").click(function (){
		var ztreeIds = $("#sortId").val();  
		if(ztreeIds.trim()!=""){  
	        var ztree = $.fn.zTree.getZTreeObj("menuTree");  
	        var ztreeId = ztreeIds.split(";");  
	        for(var j=0;j<ztreeId.length;j++){

	            var node = ztree.getNodeByParam("menuId",ztreeId[j]);  
	            var parent = node.getParentNode();  
	            if(!parent.open){  
	               ztree.expandNode(parent,true,true);  
	            }  
	            ztree.checkNode(node , true,true);   
	        }
