Manual Focus Vs. Focus()
May 20, 2007
I'm attaching an onfocus event handler to an anchor tag like this:
if(window.attachEvent) anchor_node.attachEvent('onfocus', gotFocus);
if(window.addEventListener) anchor_node.addEventListener('focus',
gotFocus, false);
function gotFocus() {
alert('i got focus');
}
Is there any way to tell the difference between when this anchor is
focused by a user (perhaps by tabbing to it) as opposed to when I
programatically do it via anchor_node.focus()?

I'm currently making a web application which needs to be fully compatible with iPad. The functions I've implemented so far work perfectly on Firefox, Internet Explorer and other browsers. However, the iPad itself responds a bit different. After a certain action, I want to put focus on a textfield with the help of Javascript. Again, this works perfectly with the normal browser, the iPad browser however seems to be blocking the focus. The reason I'm not posting any code is because it's basically irrelevant. All I do is:

Is there a reason why setting focus to a textbox input, also gives
focus to a submit button on the page, to where if you click enter in
the text box, the submit button will be clicked.

The default behaviour of focus() method is displaying the cursor at start of the char(In FF focusOffset is 0(zero) and anchorOffset is 0(zero)). I need to display the focus at end of char after calling focus() method.

I think the problem is cause by my lack of understanding of how the browser (firefox 3.6.3) handles focus.A simplified version of my problem is:I've defined the function
function two_focus()
{
document.getElementById("two").blur();

Is there a way to set the focus on a form field without using focus()? I use ajax to build the form and if I try to set the focus using focus() an error is generate because of the form hasn't been built by ajax. So, it would be nice if I could set the focus() as I built the form.

When a website is loaded, is there anyway of using Javascript to get the address bar focus and delete the contents?
I'm not sure if there would be restrictions on doing this because of security reasons

When I validate a form on submission I use the javascript focus function to
scroll the page to the location of the form error e.g.
document.[Form Name].[Field Name].focus();
If you happened to have the page scrolled above where the error field is
then the page will scroll so that the error field is at the very top of the
window. If you happened to have the page scrolled below where the error
field is then the page will scroll so that the error field is at the very
bottom of the window. Neither of these is very desirable. Any way to get the
error field to the middle of the window?
e.g. in javascript after the focus statement, can one test the location of
the error field and then either add half a windows worth of pixels to it if
it is at the top of the screen or subtract half a windows worth of pixels to
it if it is at the bottom of the screen?

If I use the following construct in the frame "main" for a link to an
extern site:
<A HREF="http://www.any.xy" TARGET="extern">
the Browser is creating the window "extern", loading the page
www.any.xy an setting the focus to "extern". But when I go return to
"main" without closing "extern", a click to an other link (e.g.
www.2nd_any.xy) on "main" does not setting the focus to "extern".
For setting the focus to "extern" in the second case, I have used the
following construct:
<A HREF="http://www.any.xy" TARGET="extern"
onClick="setTimeout('extern=window.open('','extern');fr emd.focus();',500);">
an example</A>
This construct has worked very well for a few years, but since about
one year, the sesult was the same as using
<A HREF="http://www.any.xy" TARGET="extern">
In this year, I have changed:
win 95 --> win 2000
modem 56k --> DSL
Netscape 4.5 --> Netscape 7.1
Can anybody tell me a possibility setting the focus to "extern" in the
second case? Is the changing of my configuration the reason, that the
construct has failed?

Neglecting the annoyance factor for a moment, is it possible to keep one browser window at the screen forefront (in front of all other browser windows) but still be able to interact with a window directly beneath it? How would this be pulled off in JS?

I encountered some strange behaviour when using focus()
I use a form with several input-fields. A user can enter stuff. After
entering I want to check the value, i.e. that a number is only a
number etc.
I therefore started editing a Javascript. For test purposes it only
popup a message and sets the focus. In fact this is what I want to do,
but the scipt isn't it doing right.
Here is the script:

I'm trying to do default focus on checkbox,its work fine but the

visual sign and on the other hand if you press on the tab button there
is a visual sign).

I have a date validation function that I want to stay at the object I am
validating if there is a Validation error, but it always goes to the next
object.
The javascript:
function ValidateForm(me){
var dt=me
if (isDate(dt.value)==false){
dt.focus()
return false
}
return true
}
The html:
<input name="AbsentFrom1" type="text" size="10" id="AbsentFrom1"
onBlur="return ValidateForm(this)" />
I do get the error box in my other function (isDate) and it is doing the
dt.focus().
Why doesn't it stay there?

I have a page that has 3 different iframes in it. The bottom iFrame
continually gets updated as the user adds different images to it
through the interface, and once the user clicks one of the images, I
change the style of the image to put a border around it.
The problem is, once I set off this function to put a border around the
clicked image, the iFrame resets itself. So, if I've scrolled over to
the right a bit and clicked on a pic, the frame resets itself all the
way to the left, so the user would have to scroll back over to see the
pic they just clicked.
I've tried doing an onFocus in the function that adds the style, and
it's not working.
identity=document.getElementById(picid);
identity.focus();
Any ideas?

Ive got a really simple problem but I can't figure it out. I've got a
form named bob with one text box name bobtext with a default value of
"http://". When I add onload="document.bob.bobtext.focus()" it focuses
on the text box, but at the beginning. Is it possible to focus on the
text box, but at the end of "http://"? This seems like something easy
so I'm probably making some stupid mistake.

this is for a browser window that contains a chat app that is an applet... when browser window is not in focus I would like users to somehow get notified when a message arrives, more or less like regular IM apps do.. I did with window.focus(), but I don't really want window to come into focus, I just want it to 'blink' and then stay highlighted.. I tried window.setActive() method (not sure what that method does but wanted to try it) but I get obj-non-supported error in
IE6 with that method ..

Currently in my html document I use the onload command inthe body section to
set the focus to a certain field. eg
Is there a way to set the focus to another field in a different frame other
than the one that the current document is in?
In my example, I have a frame called "top" that I would like the focus
setting to whenever a certain document is loaded in the frame "main".

I thought this would be really simple, but i'm stumped. I'd like to validate some data without submitting the form, but i can't seem to get the focus to go back to the field with the bad data. I've stripped out most of the code just to illustrate the problem. In both IE and Mozilla, the focus still goes to the next element. This is .php generated.
<html><body><script type="text/javascript">
var numAdults=5;
var numChildren=0;
function Check(element){
value=parseInt(element.value);
if(isNaN(value) || value<0 || value>99){
if(element.name=='txtNumAdults'){
element.value=numAdults;
}else{
element.value=numChildren;
}
element.focus();
return false;
}else{
//SetDirty(element);
return true;
}
}
</script>
<form action="a1.php" method="POST" name="myFrm">
<table>
<tr><td align="right"><label>Adults:</label></td>
<td><input type="text" name="txtNumAdults" size="3" value="5" onChange="Check(this);" /></td></tr>
<tr><td align="right"><label>Children:</label></td>
<td><input type="text" name="txtNumChildren" size="3" value="0" onChange="Check(this);" /></td></tr>
</table></form></body></html>
