Two JS Questions In One: Giving Focus, And Clearing Form (read Inside)
Jul 23, 2005
Okay, how do I write a page with a form so that when I click Submit,
the following happens?
1. The data is submitted (of course)
2. The form is cleared (what I've tried results in the form being
cleared first, resulting in an empty submission), and
3. The cursor goes back to the start of the form, ready for more input
(kind of like how Google puts the cursor in the search box at the
start).
I can't seem to find the answer, and I've been looking on the net for a
few hours already.

is there any way I can get what field has focus in the form? I would
like to trap the "backspace" only if focus is on spesific field.

So I'm trying to build a rostering system based on findmyshift.com - they have a free demo which I have used to get ideas and I really like the way they handle the editing of shifts - my problem is I can't figure out how to give a div focus as it were. If I could work out how to tell which div has been clicked, then get that div to listen for keypress events, I would be well on my way

I have an intranet page which has an iframe which links to a number of
different possible .NET pages.
In one of the embedded .NET pages (and soon to be others) we want to be
able to capture keystrokes in order to link to other apps. we do this
by setting document.onkeydown to a function which handles the various
possibilities.
The problem I have is that when the intranet page loads with my .NET
page in its iframe, focus is not given to the .NET page, and so in
order for the page to capture keystrokes you have to click on the
contents of the iframe, which is both clunky and (it seems to me)
unnecessary.
How do I automatically give focus to the contents of the iframe when it
loads up? I've tried putting the following script at the bottom of the
intranet page itself, but this doesn't seem to work:

On this page http://bit.ly/gAajO3 I have a comment form and would like the input and textarea contents to turn to blank when a user clicks on them, however this is not working for me. Would like to know what is going wrong if someone can spot it.Also on submit I want the input and textarea to be cleared if their value is 'Please type here'. This is working on the name input and textarea, however it seems the email field is not being cleared,

Trying to create a method/function how ever you want to call it, that will allow me to clear input values on inputs with focus() and restore the input values if nothing is entered or keep what the user types on focusou().[code]

I would, first, like to know, when someone hits a submit button and a form
is sent, how could you get that form sent as text instead of an attachment?
And second, how do you get the user to be able to browse for an image on
his/her computer and load it to a form?

I have a page with multiple text fields, each of which has an example for an initial value. I've added the appropriate code so that onFocus() the example is cleared away, and a blank field is left behind. Trouble is, I only want that to happen once, so that the field isn't cleared if the user attempts to edit what they wrote earlier. Anybody know of a way to do that with only a few lines of code? Here's my existing code:
Code:
<script language="JavaScript">
<!--
function clearField(fieldName) {
fieldName.value = "";
}
// -->
</script>
<p>Person's Name: <input type="text" name="name" size="30"
value="John Smith" tabindex="2" onFocus="clearField(this)"></p>

I have a page with 5 sets of form fields. Each field set has a checkbox that if checked will allow users to utilize it. I want to clear the given field set when the user un-checks the check box. As you can see in the code below this method will make for a very long and cluncky script, I would like to make it more generic.
<script>
function clear() {
window.document.roles.foo1.checked = ''
window.document.roles.foo2.checked = ''
}
</script>
<input class="checkBox" />
<input checked name="foo1" type="checkbox" class="checkBox" />
<input checked name="foo2" type="checkbox" class="checkBox" />

I installed a JS form dependency script. Basically if a checkbox is checked Field A will disappear and Field B will take its place.The script appears to work fine. The problem I am having is this. If someone submits the form using the Field B entry and then they need to submit a form using the Field A entry, the Field B entry is still being passed even though is it is not displayed and Field A has a value in it!So I guess my question is, how do I flush out the form field after the form is submitted? This is just happening with the fields where there is the JS Form Dependency script involved.

I have the following code that I'm using to cycle through each element in a form field, and clear whatever text is in it. If the user clicks out of the field without typing anything then the script is supposed to return to whatever value it started with (e.g. "Enter your name..."). If the user does type something, then it stays in the field even when they click out of it:

I've read a few solutions to this, but none seem to fit what I'd like to do. I'm quite new to JavaScript, so I'm trying to learn various solutions to problems and also what can and can't be done.
What I'd like to know is can you, on submit, check all the form values on a page, or indeed within a specific form on a page, for their default values, and if any still have their default values as the text within that box, clear that value.
So using some generic form values as an example, if I had a form that had three text fields Name, Email, and Phone, all by default populated by their respective names, if someone changed the value of Name to "Adenv" but left the other two, on submit the script would change the values to:
With *blank* indicating a blank field. Is this possible?

I am using jQuery AJAX to submit a form. When the data has been validated successfully and processed, I want to clear the form, but I am unsure how. I have been trying to make it work for a few hours now.
I am showing status messages in the container below:
When everything was successful, it looks like this:
And here is the simple code I use to clear the text fields:
What I need is a way to check if everything was successful and if so, then run the code above. I tried to do it in a few ways, but it kept clearing regardless of the status.

I have this page below which I run locally that is created dynamically: [URL]
I need a piece of javascript to focus on the captcha as shown in the image inside the green box. At this minute I have this which doesn't work all that great for some reason but it gets it to the general area...
if (( document.URL.indexOf("cast_skills") != -1 ) || ( document.URL.indexOf("security_prompt") != -1 ) || ( document.URL.indexOf("joinraid") != -1 )){
if ( document.forms.length > 0 ) {
document.forms[0].elements[1].focus();
}
}
As I said this does the job to some extent however it does not leave the focus in a perfect position so that the captcha is readable and the text box visible to type in, as illustrated in the red box in the above image.

I'm using the form validation and it's working great. But the form reset button, although it clears the form fields, does not clear the errors. My page header has this code so far:
[Code]....
I'm trying to understand how to implement the following in order for the reset button to do that:
var validator = $("#myform").validate();
validator.resetForm();
I'm not an experienced JS person but have a lot of other programming experience (vb, vba, mssql, delphi).

I'm having problems with applying focus() to an element inside a blur() event handler. I get different results in different browsers. Specifically, IE and Opera seem to work fine, Firefox doesn't seem to do anything, and Chrome and Safari only do half of the job. Basically, I have an <input> with a blur() event handler attached to it. The event handler contains the code to apply focus to that same input, effectively disallowing the user to remove focus from the input.

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.

I am using this browser that came with an sbcglobal account and when
I click on the built in "shopping" button (and others), sometimes i get
a jscript runtime error. It happens often but not always. It is very
annoying. When I launch the debugger I don't know what i am looking at.
My question is. Is there anything I can do to stop this from popping
up? Or is this caused by the source from the site?
Is Javascript build in to the browser or is there someway i could update
it. Would that help?
Would using a different browser help? I think this is sbcglobals own
browser but it might be based on IE.

The trouble is, is that some pages are very long and some are very short, so using offsetTop is obviously not bringing the form into full view ;-( Still keeping all the functions detailed in the code below, how would you adjust the code to achieve the aim of always showing the form, when clicking on the button to show the form, regardless of how long or short the page is please?

I'm trying to find out how JavaScript manages its memory. In
particular when using the 'new' operator to create an object is it
necessary to explicitly delete this object (before it moves out of scope,
like c++) or does JavaScript clean this up automatically?
What about string varaible which uses concatenation extensively?
