Xml for the tree:<br>

<xmp>

<tree..>

there is an event handler for click processing:
|
|
<xmp>
|
|
tree.setOnClickHandler(doOnClick);
|
|
function doOnClick(nodeId){
|
|
var myUrl = tree.getUserData(nodeId,“myurl“);
|
|
window.open(myUrl);// or frames[“someframe“].location.href = myUrl
|
|
}
|
|
</xmp>

</div>

<!-- -->
|
|
<a name="spec_dnd_out"><h3 >Drag-n-drop outside tree</h3
|
|
></a><div style="display:show" class="block">
|
|
Any page control can be set as “landing zone”. Here is an example:
|
|
<xmp>
|
|
<div id="treeboxbox_tree" style="width:200;height:200"></div>
|
|
<input type="text" width="120px" id="sInput">
|
|
<script>
|
|
tree=new dhtmlXTreeObject("treeboxbox_tree","100%","100%",0);
|
|
tree.setImagePath("../imgs/");
|
|
|
|
//user defined drag and drop control with event handlers inside
|
|
function s_control(){
|
|
//action occures on drag
|
|
this._drag=function(sourceHtmlObject,dhtmlObject,targetHtmlObject){
|
|
targetHtmlObject.style.backgroundColor="";
|
|
targetHtmlObject.value=sourceHtmlObject.parentObject.label;
|
|
}
|
|
//action occures on drag moved in landing zone
|
|
this._dragIn=function(htmlObject,shtmlObject){
|
|
htmlObject.style.backgroundColor="#fffacd";
|
|
return htmlObject;
|
|
}
|
|
//action occures on drag moved out landing zone
|
|
this._dragOut=function(htmlObject){
|
|
htmlObject.style.backgroundColor="";
|
|
return this;
|
|
}
|
|
}
|
|
//set input control as “landing zone”
|
|
tree.dragger.addDragLanding(document.getElementById('sInput'), new s_control);
|
|
