This function will add a function that you give it to a list to be executed when the DOM is done loading.
[syntax=javascript]// adds a function to the windows load event.
function add_onload (func) {
if (typeof window.addEventListener !== 'undefined') {
window.addEventListener('load', func, false);
} else if (typeof window.attachEvent !== 'undefined') {
window.attachEvent('onload', func);
} else {
if (typeof window.onload !== 'function') {
window.onload = func;
} else {
var old_onload = window.onload;
window.onload = function () {
old_onload();
func();
}
}
}
}[/syntax]
It will work in all browsers, and has a fallback to the old window.onload method in case any of the correct methods are not available.
example useage...
[syntax=javascript]add_onload(function () {
alert('test 1');
});
add_onload(function () {
alert('test 2');
});[/syntax]
Will show the two alerts once the HTML for the page has finished loading.
