So I have a control (a map) on an aspx page. I want to write some javascript to onload setup the following:
when mouse stops on control = some code
when mouse moves = some code (but only if the move is longer than 250 mil sec)
This works to trigger code on stop and then on move...
function setupmousemovement() {
var map1 = document.getElementById('Map_Panel');
var map = document.getElementById('Map1');
map1.onmousemove = (function() {
var onmousestop = function() {
//code to do on stop
}, thread;
return function() {
//code to do on mouse move
clearTimeout(thread);
thread = setTimeout(onmousestop, 25);
};
})();
};
But I cannot figure out how to introduce a delay into the on move code. I thought I had it with this...
function setupmousemovement() {
var map1 = document.getElementById('Map_Panel');
var map = document.getElementById('Map1');
map1.onmousemove = (function() {
var onmousestop = function() {
//code to do on stop
clearTimeout(thread2);
}, thread;
return function() {
thread2 = setTimeout("code to do on mouse move", 250);
clearTimeout(thread);
thread = setTimeout(onmousestop, 25);
};
})();
};
But it does not behave as I thought it would. The on move "thread2" is never cleared by the stop. What am I missing?
That is a tricky one. A little bit of tinkering resulted in this:
The reason your code does not work is that mousemove fires repeatedly while the mouse is moving and you are starting new timeouts every time.
