Although it's hard to believe you have enough of a delay just showing content to warrant a loading bar, I think the problem you're having is that the window won't update during your function. You might try doing a setTimeout to finish the function and give the window a chance to update...

function Toggle(which, under) {
	var visible = document.getElementById (which).style.display != "none"
	//This is the div that should be expanded or collapsed.
	var obj = document.getElementById (which);
	//This is the div that is clicked to change the plus/minus sign.
	var sub1 = document.getElementById (under);
	var obj1 = document.getElementById ("menus");

	if(obj.style.display = "none") {
		obj.style.display = "block"
		sub1.innerText = "–"
	}
	obj1.style.display = "none";
	if(visible) {
		obj.style.display ="none"
		sub1.innerText = "+"
	}
}
function startToggle(which, under){
	var obj1 = document.getElementById ("menus");
	if(obj1.style.display = "none")
		obj1.style.display = "block";
	setTimeout("Toggle('"+which+"','"+under+"')",1);
}

And then call startToggle() instead of Toggle().

Also a better method of showing the loading tag might be to dynamically add it to the required menu tag via appendChild, then removing it when done...just a thought.

Take this mini example

<HTML>
<INPUT TYPE=button ID=btnEmergency VALUE="CLICK!" onclick="startToggle('Link1')"/>
<div id='Link1' style='display: none'>
krikor
</div>
</HTML>

<script>
function startToggle(value)
{
var target1 = document.getElementById(value);
if (target1.style.display == 'none') {
target1.style.display = 'block';
} else {
target1.style.display = 'none';
}
jsWaitForDelay(5000);
if (target1.style.display == 'none') {
target1.style.display = 'block';
} else {
target1.style.display = 'none';
}
}


      function jsWaitForDelay(delay) {

      var startTime = new Date();
 
      var endTime = null;
  
      do {
 
      endTime = new Date();
  
      } while ((endTime - startTime) < delay);
 
      }
</script>

on button click, i show the word krikor.. and after 5 seconds i disappear it. it doenst work

when i add alert("here") after jsWaitForDelay(5000);..
it waits 5 seconds..show the word and alert bxo together..and then disappears

so why is this happening? why on alert box? it stops and shows everything..and when no alert box..the function has to finish so that all changes show up

When you use the alert function it forces the window to update. Using setTimeout will have the same effect. The key is to use the setTimeout right after you display 'krikor' and point it to a second function that does the rest. Here is how you would use it in the example you gave...

<HTML>
<INPUT TYPE=button ID=btnEmergency VALUE="CLICK!" onclick="startToggle('Link1')"/>
<div id='Link1' style='display: none'>
krikor
</div>
</HTML>

<script>
function startToggle(value){
	var target1 = document.getElementById(value);
	if (target1.style.display == 'none') {
		target1.style.display = 'block';
	} else {
		target1.style.display = 'none';
	}
	setTimeout("endToggle('"+value+"')",1);
}
function endToggle(value){
	jsWaitForDelay(1000);
	var target1 = document.getElementById(value);
	if (target1.style.display == 'none') {
		target1.style.display = 'block';
	} else {
		target1.style.display = 'none';
	}
}


      function jsWaitForDelay(delay) {

      var startTime = new Date();
 
      var endTime = null;
  
      do {
 
      endTime = new Date();
  
      } while ((endTime - startTime) < delay);
 
      }
</script>

I worked it out with settimeout, very much thank you for the help.

The code i posted here are just testings. i am actually getting data from database and creating the div's dynamically..

its a tree, when node is clicked i want loading... to be appeared until i get data from database and generate its childs...

settimeout did it perfectly. i implemented it on main program and worked out
