index.html

HTML Code:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN"
   "http://www.w3.org/TR/html4/frameset.dtd">

    <head>
        <title>Spiders ewww...</title>
    </head>
    <frameset rows="1%,99%">

Frames are very very very rarely useful and if the site "useful" but is in frames, it negates it's usefulness by making it unusable.

BUT only javascript function calls in the href attribute needs to be prefixed with "javascript:"

**chrishirst** · 10-02-2008, 06:36 AM

same answer as in your other question.

**Raisdead** · 10-02-2008, 08:39 AM

I changed the
<a href="" onmouseover="javascript:exec();">test</a> to
<a href="" onmouseover="exec();">test</a>

and it is still unopperational

thank you for that piece of information though

**Raisdead** · 10-02-2008, 08:45 AM

I tried removing the javascript: on the onkeypress to just the function name and the

document.body.onkeypress = "function2()";

still does chnage the onkeypress in the <body> tag

**chrishirst** · 10-02-2008, 09:07 AM

which browser? any error generated?

link? ( remove the reference to the illegal site first)

**chrishirst** · 10-02-2008, 09:08 AM

both threads on same topic merged

**chrishirst** · 10-02-2008, 09:14 AM

functions are defined as

function functionName(parameters) {
actions to be done by the function;
}

this is the full html

    function contents() {
        document.getElementById("main").innerHTML = '<div>HTML CUT FOR    UNDERSTANDING</div>' ; 
        document.body.onkeypress = "vcredits()";
    }
    function vcredits() {
         alert('2');
    }

Firefox; chrome; ie 5-7; no error...

**chrishirst** · 10-02-2008, 09:20 PM

javascript is case sensitive

onkeypress should be onKeyPress

**Raisdead** · 09:13 AM

I changed the onkeypress on the javascript to onKeyPress and i still never get the vcredits() function to replace the contents() function on the <body onkeypress="contents()"> (proff is that i never get the alert('2'); message when i press a key...)

if this helps

current working html

the function name should NOT be in quotes.

You are assigning a method to the event NOT a string

**Raisdead** · 09:17 AM

This executes the function right away I want it to wait till i press a key again other wise i would just put the function at the end of the contents() function...

I know i didnt say that in my message but now you know

i edited the html in the message above to represent the change

This might help or might not...

I put the following line in the beginning of the contents() function

alert(document.body.onKeyPress);

i received an alert that said undefined the first time

then every time i press a key on the same page it says vcredits()

For that you need to use the onKeyUp event to set the body.onKeyPress to a new function, otherwise it will execute straight away because (obviously) there is a key down.

As it would. It is displaying the name of the function assigned to the object.

**Raisdead** · 10-03-2008, 05:49 PM

I still get the 2 two alerts in a row meaning that the functions are executing back to back

Does anybody have any questions to help me solve this problem

**chrishirst** · 05:09 AM

Tried to get this to work, and it won't.

The basic problem is that you are changing the event that is still active, so it will trigger the new event instantly.
Even toggling the events by using the onkeyup event to change the onkeypress event still triggered the second event.

You will probably need to start playing about with time delays to set the functions.
