Compatible with JS scripts in Firefox

Recently I made a project and encountered the problem of incompatibility between FireFox and IE scripts. For this reason, I collected some compatible scripts from the Internet, and I also found out a little bit, I wrote it in another blog of my own and copied it for your reference.

1. Windows. event compatible scripts

Function getEvent () {// gets browser events, and is compatible with ie and ff writing.
If (document. all) return window. event;
Func = getEvent. caller;
While (func! = Null ){
Var arg0 = func. arguments [0];
If (arg0 ){
If (arg0.constructor = Event arg0.constructor = MouseEvent)
(Typeof (arg0) = "object" % 26amp; % 26amp; arg0.preventDefault % 26amp; % 26amp; arg0.stopPropagation )){
Return arg0;
}
}
Func = func. caller;
}
Return null;
}

Before each event is used, Firefox needs to use getEvent () to obtain it. Otherwise, it is null.

2. Shield Form submission events

Event. returnValue = false; // for IE

Evt. preventDefault (); // for firefox

3. Obtain the event Source

Var source = event. srcElement // IE

Var source=event.tar get // firefox

4. Add event compatibility

Function addEvent (oElement, sEvent, func ){
If (oElement. attachEvent ){
OElement. attachEvent (sEvent, func );
}
Else {
SEvent = sEvent. substring (2, sEvent. length );
OElement. addEventListener (sEvent, func, false );
}
}

Usage addEvent (window, "onload", Start );

5. How to register innerText in Firefox

// Register firefox innerText
HTMLElement. prototype. _ defineGetter _ ("innerText ",
Function (){
Var anyString = "";
Var childS = this. childNodes;
For (var I = 0; I if (childS [I]. nodeType = 1)
AnyString + = childS [I]. tagName = "BR "? '\ N': childS [I]. innerText;
Else if (childS [I]. nodeType = 3)
AnyString + = childS [I]. nodeValue;
}
Return anyString;
}
);
HTMLElement. prototype. _ defineSetter _ ("innerText ",
Function (sText ){
This. textContent = sText;
}
);

6. The length of FireFox must be "px". IE doesn't matter.

7. The sub-control IE under the parent control is "children", and FireFox is "childNodes"

8. XmlHttp

In IE, the content of the XmlHttp. send (content) method can be empty, while firefox cannot be empty. send ("") should be used; otherwise, error 411 may occur.
