Hi Friends...
I have an query on how to capture onFocus event for all the input
controls without writing onFocus event in the <input> tag.
say my html form has 3 or 4 or 5 input text boxes, now I want to
capture onFocus event for all the text boxes without writing onFocus
code in <input> tag.
for example:
<form name="frm1">
<input type="text" name="t1">
<input type="text" name="t2">
<input type="text" name="t3">
</form>
now in above example whenever user shifts the focus to input 1 i.e. t1
box, then some action should be taken say alert message is displayed,
then when focus shifts to input 2 i.e. t2 box, then same action is
displayed & alert message is displayed. for this I dont want to write
code given below:
<form name="frm1">
<input type="text" name="t1" onFocus="alert( 'hi')">
<input type="text" name="t2" onFocus="alert( 'hi')">
<input type="text" name="t3" onFocus="alert( 'hi')">
</form>
If some body could help me.....
Thanks in Advance

var inputs = frm1.getElement sByTagname('inp ut');
for(var i=0; i < inputs.length; i++) b
inputs[i].onfocus = function {
alert('hi');
}
}
or
var inputs = frm1.getElement sByTagname('inp ut');
inputs[0].prototype.onfo cus = function {
alert('hi');
}
I didn't test those, and I might be a bot off with the syntax, but this is
the direction to look at.

It would be best to use a single function and assign its reference, rather
than create an anonymous function for each element.
}
or
var inputs = frm1.getElement sByTagname('inp ut');
As above.
inputs[0].prototype.onfo cus = function {
I don't know how successful that will be. Some browsers may not provide a
prototype for the element. The single function argument above applies
here, too.
alert('hi'); }

It's a shame that IE is such a pile of crap. If it supported event
capturing (as introduced in DOM 2 Events), this would be so much easier.

Hello,
I have created a form and assigned each of the form elements to a
class in a style sheet.
I would like to know if it is possible to add 'OnFocus' and 'OnBlur'
events to the style sheet class so that I can change the background
color of a form element WITHOUT having to add 'OnFocus' and 'OnBlur'
events to each individual form element..

Hello,
I am using mozilla and javascript to change the style background color
for my select with onfocus() and back to white with onblur().
When i process onfocus(); i have to click on the select three times to
get the popup menu and everything seems slow. No errors are reported
in the console however it seems as if the click event is not being
processed after the focus event is processed.

I've got a default value of some text in an input element when a page loads.
What I'd like to do is have the value disappear when the user clicks in the
input field.
I've figured out I can use:
onclick="this.value='';"
This works fine, however if for some reason the user adds his own input,
then click somewhere else/clicks back, the text has once again been erased.

Hey all. I'm working on some VERY big forms, and the user will easily
lose their location if they get distracted - which happens a lot with
the amount of phone traffic they get.
Anyway, I have a function like this:
function initForms(){
for(i = 0; i < document.forms.length; i++){
for(j = 0; j < document.forms.elements.length; j++){
el = document.forms.elements

Hi All,
In Mozilla Firefox, to onblur and onfocus event of each and every
html element, the browser itself will attach a native event handler. I
mean if you type, 'javascript:alert(window.blur)' in the address bar
of Firefox browser, you can see a 'function ....' . That is a Firefox
browser defined handler.
Now assume that web developer also attach event handlers to 'onblur'
events eg: 'window.blur=f3()'
