Hi guys! I'm wondering how to use "addEventListener" resp. "attachEvent" correctly!?
window.onload=function(myFunc1){ // do something }
function myFunc2(){ // do something }
if (window.addEventListener){ window.addEventListener('load', myFunc2, false); }
else if (window.attachEvent){ window.attachEvent('onload', myFunc2); }
...
or
function myFunc1(){ // do something }
if (window.addEventListener){ window.addEventListener('load', myFunc1, false); }
else if (window.attachEvent){ window.attachEvent('onload', myFunc1); }
function myFunc2(){ // do something }
if (window.addEventListener){ window.addEventListener('load', myFunc2, false); }
else if (window.attachEvent){ window.attachEvent('onload', myFunc2); }
...
?
Is this cross-browser secure or should I better go with sth. like this:
function myFunc1(){ // do something }
function myFunc2(){ // do something }
...
function addOnloadEvent(fnc){
if ( typeof window.addEventListener != "undefined" )
window.addEventListener( "load", fnc, false );
else if ( typeof window.attachEvent != "undefined" ) {
window.attachEvent( "onload", fnc );
}
else {
if ( window.onload != null ) {
var oldOnload = window.onload;
window.onload = function ( e ) {
oldOnload( e );
window[fnc]();
};
}
else
window.onload = fnc;
}
}
addOnloadEvent(myFunc1);
addOnloadEvent(myFunc2);
...
AND: Say "myfunc2" is for IE 7 only. How to modify the correct/preferred method accordingly?
Thank you so much!
