[java script] different browsers

[DaveR]

Hi,

I have the following code on an asp page and it works fine from a mozilla bowser but when run from internet explorer is doesnt seem to work at all.

function Approach (theform) {
var pregen = 0 ;
pregen = theform.sel_app_1.value
alert(pregen)
return;
}

called from a select box as follows.
onChange= "Approach(this.form) ;"

With the mozilla browser it displays the selected value

With internet explorer it just displays the default value of 0

If any one has even the slightest idea of what the problem is here , please let me know.

Thank

How are you getting that to run without semicolons in place?

[DaveR]

There are semi colons on the code on the page, deleted them by accident on the post.

I've never used the this keyword in js before... I'd normally just use document.myform or something to that effect...

[DaveR]

Even when I use the the actual form name in the function , ie. in effect ignoring the input parameter, it still gives me a value of 0 .

Why not:

<textarea onchange="Approach(this)"></textarea>
...
function Approach (_obj) {
var pregen = 0 ;
pregen = _obj.value
alert(pregen)
return;
}

I am calling it from a drop down select box, eventually I want the function to do calculations on a few different drop down boxes on the form.

Functions calls ok ,but it just cant read the selected value of the dropdown box.

<select onchange="Approach(this.value)">
    <option value="abc">abc</option>
    ...
</select>

Its in the function the problem is:

function Approach (theform) {
var pregen = 0 ;
pregen = theform.sel_app_1.value; alert(pregen);
return;
}

theform.sel_app_1.value gives me a value of 0 no matter what I select.
Works fine in mozilla.

It's a faulty implementation on IE's side:

A good reason always to use the value attribute.
