Trying To Work With Onfocus
Jul 23, 2005
Here is the layout of my form from left to right, from top to down.
- buttonA, buttonB, buttonC
- textbox, textbox, textbox
- buttonXXX
After the user types in the textboxes and press enter (with the cursor still
in one of the textboxes), buttonXXX should be pressed by default.(the user
is too lazy to take the cursor over to buttonXXX and click).
The problem is the top/left most button (button A) gets pressed which annoys
them to death. So I tried to do this.
In the bottonA's onfocus event handle-
document.forms[0].elements['buttonXXX'].focus() .
Result: ButtonXXX receives focus alright, but the code for buttonA still
executes!

I have a page with a textbox that I want to have a message written inside it that will dissapear when the user clicks in the text box and writes something and it will show up again if the user clicks somewhere else but hasn't written anything inside the textbox. So I am using the onfocus event in order to write "Enter your email here" and the onfocus event in order to show the "Enter your email here" message inside the textbox if the user clicks somewhere else in the webpage but has left the textbox blank. If however the user has written, for exampl "jim@yahoo.com", I want this to remain in the textbox.What am I doing wrong?

For those who have been using Outlook Express, you must be pretty used to
the fact that whenever you focus on the preview section, the header for the
preview turns from grey to blue, while the text turns from black to white.

I'm fairly new to this and my code is as follows...
<script language="JavaScript>
var oldValue
function focusElement(theElement) {
oldValue = theElement.value;
return;
}
</script>
Then in the HTML, I have
<select size="1" id="ConfCommentSELECT" name="ConfCommentSELECT"
onfocus="return focusPrecedence(this);">
<option value="0"> - </option>
<option value="1">1</option>
<option value="2">2</option>
</select>
The <select> is with a <form><tr><td>, but I don't see how that would make a
difference. I started using the onchange="return blah-blah-blah(this);" and
that worked so I copied that to the onfocus. What I want to do is to
remember the value of the contents of the <select> before the user changes
it, and compare it to the new value.

I'm developing a website where a visistor does not have to use the mouse.
All he has to do is use the Tab-key or key-combinations to jump to specific
hyperlinks (containing accesskeys). Next, he presses the Enter key to follow the hyperlink.
My question is: is it possible to change color of the hyperlink when a
hyperlink get the focus. I do not only want to see the dotted line, I want the hyperlink to lighten up.

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.
So I thought of a function like the following, however it does not work:
function removeinput(x) {
if (x == 'Enter items not on standard list here...') {
x = ''
}
}
onclick="removeinput(this.value);"
I've also tried placing this.value inside of single quotes to no avail.

I'm trying to use javascript to control a table's td styles. What I want to achieve is to
- apply style A onmouseover
- apply style B onmouseout
- apply style A onfocus
The problem is that the mouseout event overrides the focus event. Also I'd like each element to stay on the focus state until another element gets clicked.
This is my code:
<script language="javascript" type="text/javascript">
function HoverStyle(element) {
document.getElementById(element).style.backgroundImage = "url(images/arrow1.jpg)";

i'm sure its been thought of before and i'm sure this is just gunna piss off the people who like to tab through their pages, but i just made a little behavior component file that stops any links from gaining focus on your page.
put this is the style section of your page.
<style type="text/css">
a { behavior: url("hidefocus.htc"); }
</style>
then put the attached file in the same dir. (hidefocus.htc) this is all it is
<public:component>
<public:attach event="onfocus" handler="blurry" />
<script>
function blurry() {
element.blur();
}
</script>
</public:component>
Note: since this behavior is stored in an external file, sometimes one instance of link focus can occur before the htc file can be loaded. if anyone has any tips on fixing that i'd like to hear'em.

In my UI framework, I have an event handler - just like many frameworks do. My handler is a static object, and contains methods to take care of things like mouse events, etc. However, upon adding a method to handle onfocus today, I ran into a very odd problem in Firefox. I've put together an example page that generates the error:

I want to have a function on an event
<span id= "nameheader"> </span>
<form method ="post" action="send.php">
<input
id = "nameinput"
class = "input"
value = "name"
onfocus = "focus();"
onblur = "blur();"
/>
That is when you focus on the input box the value ' name' gets put above the box and when you focus on something else it goes back to the box.
this is my function
focus(){
document.getElementById('nameheader').innerHTML = 'name';
document.getElementById('nameinput').value = '';
}
And I would obviously do the opposite for onblur event.

I'm working on a JSP application, and wish to define a text-field so
that it becomes marked (highligted) when it obtains focus.
I've tried giving the text-field a value when it obtains focus, but
the value is not marked. So if i wish to alter the value, I have to
manually delete the given 'onFocus' value before I set a new value.
<INPUT TYPE=TEXT NAME=test size=30 want this
to be highlighted!'">
I'm missing something to highlight the text-field text in the code
above.

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 have looked through the groups and it appears as if there is no way
for me to force the popup open (expand contents).
I was reading the gecko dom docs; but am not absorbing the solution.
Any thoughts as to the problem, erros, solutions?

<input class="search" type="text" value="TEXT YOU WANT" onfocus="if(this.value=='TEXT YOU WANT'){this.value='';} this.className=this.className.replace('defaultText', '');" name="search" />
This works well in all of my applications and does not depreciate in multiple browsers. It is only the search type input, you can include this in any form area to see how it works and set your custom parameters.Upon focusing on the form (E.g. entering text) the "TEXT YOU WANT" will disappear.

I created an image gallery. The way it works, I click on a thumbnail and it displays the image - This works fine. I'm now trying to use onfocus to highlight the thumbnail that I clicked on. It highlights the thumbnail but when I click on a different thumbnail the first one stays focused and the second is focused also. I want it to unfocus if I click on a different thumbnail. Can somebody give me some advice on what I should do? I'm not that great with Javascript but I got this far.

I have a text input field - a search box. As characters are entered, I use AJAX to retrieve a list of matches from my products table and display them in a simple unordered list below the search box.This works great, until the user clicks one of the matches.Because I have set the onblur event of the search box to hide the autocomplete box, when the search box loses focus as a result of one of the links in the autocomplete box being clicked, the autocomplete box is hidden and the link is not activated.How can I get the links to work, and also have the autocomplete options disappear when the search box loses focus?

There are many script on the e web that can easily do what I am looking for but they don't teach me anything. I am trying to learn this stuff, and the best way will be to know what each variable is doing, what function is being called when the thumbnail is hover or focus.
All I need is to start with a single image, when I hover on the image, a larger image appear.I know how to declare a variable, create a function, how to put these things into everyday projects is what the books never tells you.
