Hi,

I have a function that takes some time to execute. During that time i want to change the MousePointer to a hourglass. i tried some different approaches, but they all failed.

function  myfunction(){

  window.document.body.style.cursor='wait';

  imSort(); //this code takes long to excecute  

  window.document.body.style.cursor='default';

}

I saw somewhere an example with setTimeout but i could not get it to work.

this works for me :

<html>
<head>
<script>
function test()
{
window.document.body.style.cursor='wait'
}
</script>
<title>Page title</title>
</head>
<body onload='test()'>



</body>
</html>

you need this

function  myfunction(){

  window.document.body.style.cursor='wait';

  imSort(); //this code takes long to excecute  


}

function imSort() {
.
.
.

  window.document.body.style.cursor='default';

}

Hi,

Thanks for the suggestions. But they don't work for me. Maybe i did not explain well enough what i was doing. Here is a better simplified example.

<html>
<head>
<script language=javascript>
function test1(){
  window.document.body.style.cursor = "wait";
  for(i=0;i<10000;i++){
    overviewSection.innerHTML = "test" + i;
  }
  window.document.body.style.cursor = "default";
}

function sort(){
  for(i=0;i<10000;i++){
    overviewSection.innerHTML = "test" + i;
  }
  window.document.body.style.cursor = "default";
}

function test2(){
  window.document.body.style.cursor = "wait";
  sort();
}

</script>

<title></title>
</head>
<body>
<input type=button name=btn1 value="Click1" onclick="test1()">
<input type=button name=btn2 value="Click2" onclick="test2()">
<br>

start div
<div id='overviewSection'>
</div>
end div

</body>
</html>

mplungjan: as you can see i tried your solution, but the mouse pointer stays the same :(
p_partha: your solution is not really what i want, see example

I also increased the point to 150.

I just found a solution myself. This seems to work.

function sort(){
  for(i=0;i<10000;i++){
    overviewSection.innerHTML = "test3" + i;
  }
  resetPointer();
}

function test3(){
   setPointer();
   setTimeout('sort()',1);
}
function setPointer() {
    if (document.all) for (var i=0;i < document.all.length; i++) document.all(i).style.cursor = 'wait';
}
function resetPointer() {
   if (document.all) for (var i=0;i < document.all.length; i++) document.all(i).style.cursor = 'default';
}

I leave this question open for a day, in case somebody has a better solution. If there is no better solution i will delete it.

Thanks
Didier

I use the setTimeout() function.
Also the setPointer and resetPointer functions are different. With window.document.body.style.cursor='wait' it doesn't work.

I found this solution somewhere on the internet. I'm totally new to this stuff, so if you can give me a good explanation about why this works and the other solutions not, you can still have the points.

Greetz,
Didier

BTW i'm going home now, i'm back tomorrow
