How to acces a global JS-Object in another .js-File
How do i acces an object which was initialized in my HTML-Document?
My HTML-Document looks like this:
...
<script type="text/javascript" id="controller">var controller = false;</script>
...
<body onload="controller = new CTRLclass()">
....
How do I call controller.doAMethod() in an external Javascript-File using DOM-Operations or simmilar?
edit: PPL, i have开发者_StackOverflow社区 many .js-Files and my controller is creating an instance of another class in his constructor. In the created instance of the class i need acces to the controller to call an update-Function. Like: controller -> creates instance of class. class -> needs to call controller.update(). How do i acces controller in 'class' - Thats all
THX!
You don't need the onload tag to initiate onload tasks. Just put this is the external javascript file:
var controller = false;
function Init(){
controller = new CTLRclass;
}
function addEvent(el, eType, fn, uC) {
var uC = uC || true;
if (el.addEventListener) {
el.addEventListener(eType, fn, uC);
return true;
} else if (el.attachEvent) {
return el.attachEvent('on' + eType, fn);
} else {
el['on' + eType] = fn;
}
}
addEvent(window, 'load', Init);
I actually can't envisage why you would want to do the above. Simply strip out all of the Javascript in the above, so all you have is:
...
<script type="text/javascript" src="myjsfile.js"></script>
...
<body>
....
And in myjsfile.js do somthing like
window.onload = function(){
var controller = new CTRLclass();
}
If it must be global, then you can move it outside of the onload function:
var controller = false
window.onload = function(){
controller = new CTRLclass();
}
Use of jQuery would make it more elegant, of course, as you wouldn't risk overriding any existing onloads:
var controller = false
$(document).ready(function(){
controller = new CTRLclass();
});
