JQuery :: Detecting Field Value On Page Load And Clearing Field Label
Oct 14, 2010
I'm having trouble detecting if there is value in a field when the page loads and manipulating the fields label class accordingly. Below is my code. I'm using it to display the field label inline with the field, and when the user starts typing, the label is hidden. The problem I'm having is, since this is for a login screen, if the user has typed in an incorrect password, the username still remains entered when the page reloads and I see my label stacked underneath.
How can I detect if that field has a value and apply a class to the label to hide it? I don't have to have to specify each field by their ID, because I'd like to use this all over (member profile management area).

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 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 my labels on top of the fields and when an invalid field is found, validate moves the focus to the first invalid field, but when it does that the user can't see the label. How can I make it scroll up just a tiny bit to include the label? Also, wondering if anyone has implemented scrolling in general so that the page scrolls smoothly up to the error location rather than the jump you get with a focus change to an off-screen element.

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'm currently designing a form with client-side validation using javascript. I've set the input property to display as the value (for example, "your name" inside the name field) and I've set the javascript to clear value using name.focus but everytime I reselect the field to edit the value, it clears again, so I'm trying to make it so that on the 2nd time it get's selected, the nameClear funtion doesn't run.Here's what I've got so far, but it's not working. For some reason, the else statement within the function that runs on .focus is showing as invalid in my debugger, but it looks fine to me.
name.focus(function() {
if(name.val("Your name"))
name.val("");

I have a form and inside the text fields I have a note that indicates: Type here your name...all this instead of having titles for each field. That text is set as initial value and the user has to highlight the text to delete it. What I am wondering is if there is a way to have the text but when the user clicks on the Field the text disappears and there is no need for deleting. I have seen this before but I can recall where.

The online banking site I use has autofill=no set in their login form,
and I recently switched from IE to Safari, which honors this. I'd like
my account number to be filled in automatically like IE did (please, no
comments on whether this is a good idea or not, I've already had this
discussion in another group and I've decided the account number is not
something I consider a big secret, since it's visible on every check --
that's what the PIN is for).
I'm trying to do this with a bookmarklet. The following works to fill
in the account number and move focus to the PIN field:
document.Login.userNumber.value=﾿?'
document.Login.password.focus()
(newlines included to make the post easier to read, they're not in the
actual bookmarklet).
But this requires me to use two bookmarks, a regular one to load the
site, and this one to fill in the field. I'd like a single bookmarklet
that does both steps at once. I tried:
window.location='https://www.directib.com/onlineserv/HB/Signon.cgi'
document.Login.userNumber.value=﾿?'
document.Login.password.focus()
What am I missing?

I'm using Google Maps to calculate distance between cities. I need to use that distance value for some basic calculations. Distance has to be in "Angloamerican" format (1,234.00) but in metric system. So, Google Maps answer for Madrid - Berlin query will be one of these two:
a) <span jscontent="distance['text']" jsdisplay="distance" jstcache="7">2.320,1 km</span>
b) <span jscontent="distance.text" jstcache="23">2.320,1 km</span>
notice the differences in span "classes" (jstcache is 7 or 23) and lack of any "id" or "name" attributes.
What I want to accomplish is:
1) Convert these Google Maps distance values to "Angloamerican" format (2,320 km) or (even better) format without thousands separator which would only use dots as decimal separator (2320.1 km)
2) Use that filtered value to populate a text field called distance
Populate hidden form element value with the value of a text field on form submit (jQuery)
It helped me a bit with the auto-populate part, but I can't make it work in combination with this Google Maps code. Here is my current code:
<head>
...
<script type="text/javascript">
function submitMyForm(){

I have a credit card field that is only mandatory if they select a credit card as a payment type.
If they select Gift Certificate, then I set the card to not be mandatory:
$('#creditcard').removeClass('required').removeClass('creditcard');
validationRules.rules.CardNumber.required = false;
however the validation still fails on the creditcard field. If I enter this in to Firefox's console:
$("#OForm").validate().element("#creditcard");
it returns false.
To make matters more confusing, this validation only fails on my form when I am passing a particular parameter in the URL string. I've scoured my code and cannot figure out why that parameter would have any impact whatsoever on this matter.

I have a text field (field1) already displayed on the HTML page. However, there's a link where you can add additional text fields to the page as well. When the link is clicked, the second text field is added successfully (field2), and when the link is clicked again, the third text field (field3) is added successfully. However, the third field does not add itself to the page, and the text for anything greater than a third field also isn't displayed after. This obviously means that my "fields" variable is not working right
<script language="javascript">
fields = 1;
function addMore() {
if (fields = 1) {
document.getElementById('addedMore').innerHTML = "<input type='text' name='field2' size='25' /> <span>Field 2.</span>";

The following form validation script works, currently if one of the five fields are completed, a message appears the remaining field(s) must be completed etc. Although the information the user has inputted in the first field is cleared. How can this information be available, if there is one problem in the form it doesn't make sense that the user must re-input all the information again. I look forward to hearing your response,
function validate_form ( )
{
valid = true;

my javascript code is only validating one field at a time (as in it validates on field then submits the form, instead of going through the entire thing and then returning it as true and submitting it...) I'm not sure what to do to be honest, I've looked up google to no real avail.. my variables are declared in a seperate file to the actual even handlers and I have heaps of comments through out it, so please don't judge lol i'm still learning Quote:
//Event Registrations (Variable Declarations) found in validation_chkr.js
//Validate Entire Form using validate_join()
function validate_join()

i have a form with a 'name', 'date', 'type', 'style', 'color' and 'result' field.let's say the user inputs "jones" in the name field, "8/1/2011" in the date field, "new" in the type field, and 'modern' in the style field.i want the 'result' field to take a look at the 'name' field, and if the 'name' field has a particular text, let's say (in this case) "jones", the javascript code will then place the contents of 'date', 'type' and 'style' fields, along with hardwired text like "the information you are looking for is 'date', 'type' and 'style'" into the 'result' field.
