Loop For Each Label In Form 1 ?

Apr 29, 2010

How do I do this? I have ~200 labels on a page and want them all set to .style.fontWeight = 'normal';.

How can I cycle through them all without typing 200 lines of each label name?

JQuery :: Make An Image Label That When Clicked Will Change From One Label To Another

May 3, 2011

How can I make an image label that when I clicked will change from one label to another.

Let say I have index.html where my label is displayed. Then I have label01.jpg to label20.jpg stored on label sub folder.

What I want is to be able to change my label one at a time from label01.jpg to label20.jpg everytime i click the label. then go back to label01.jpg after label20.jpg

For illustration purpose, see image below. I want the label to change every click until I got the label right for the video screen. I have 20 video screen in one page and I need to change the labels depending on the video.

Actually a more preferred solution is for the script to cycle through all the pictures on my label folder so that if I have new labels I only need to dump it in the folder and it will become available.

Add Label To A Form Dynamically

Aug 18, 2006

I'm using this to add a label to a form. I'm adding new form inputs so the user can add links:

var obj = document.createElement("label");
obj.setAttribute("for", "link"); //this seems not to work in IE6

var myText = document.createTextNode("Label name");
obj.appendChild(myText);
document.getElementById("Links").appendChild(obj); //there's a void div called "Links" in the html
obj = document.createElement("input");
obj.setAttribute("type", "text");
obj.setAttribute("name", "link");
obj.setAttribute("id", "link");


In the html I use a link that calls the function to add dynamically the input and label.

It's working ok in Firefox... I mean, when you click on the label, the input get the focus (just as a normal html label tag).

But it does not work in IE6... Does anybody knows if there's some change to make it work in IE6?

Label Properties For Form Elements

Feb 14, 2003

This is pretty simple, but if you've ever wished that the DOM exposed a label property for any form element that had a label specified for it, well, you'll enjoy this.

{
var labels = f.getElementsByTagName( "label" );
for ( var i = 0; ( label = labels[i] ); i++ )
f.elements[label.htmlFor].label = label;
}

Just pass it a reference your form and voila! You now have element.label.

Inner Label In Form Text Field

Mar 11, 2009

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.

Using The DOM To Affect A Form Element's Label

Aug 7, 2004

I have a form that is validated using the DOM. If a user attempts to submit this form before completing all required fields the fields turn red. The only drawback to this is the reading the text in the fields can become difficult. One thing I was hoping to do was to have the text associated with each form element turn red insteadof the field.

Each form element's text is enclosed in a <label> tag and I figure setting that tag's font color to red would be easy enough to do...if I knew how to reference it. That's the thing, I'm not sure how to reference it.

Accessing The "for" Property Of A Form Label

May 24, 2007

I need to be able to determine what form control a label is associated with from within a script. Normally I'd access properties of items by name, like thisLink.href, or thisControl.value, but you can't do thisLabel.for becauce for is a javascript keyword. Does anyone know how to get around this problem?

Need To Loop Thru Form Elements

Jul 20, 2005

I have a dynamicly generated form (well the elements are at least) that looks something like this:

while( not end of returned records):

<input name="plan_id[]" type="checkbox" id="" value="<?=
$row_plans->planid ?>">

<input name="num_of_pockets[<?= $row_plans->planid ?>]"
type="text" id="num_of_pockets[]" value="<?=
$row_plans->num_of_pockets ?>" size="5" >

endwhile;

Basically it loops thru the table and creates a row of fields in the form that use the array identifiers '[]' so that I can loop thru them with PHP when the page is submitted.

The key for each array element is the id of the row from the database. So checkbox[] (with value "1") and cost[1] are on the same line in the form. The next line may not necessarily have cost[2] in it, it may be cost[3] or [4], depending the id from the database.

Is there some way I can loop thru these form elements in javascript?

CPU 100% On A Loop While Retrieving Form Values

Jul 20, 2005

I have a form with a lot's of number of Text and Hidden Fields. I just do a simple loop to get each value for each attribute. I have about more than 2000.

if i do something simple like :

for (var i=0; i<2000; i++)
aValue = i+10;

it runs well. But if i do something like
for (var i=0; i<2000; i++)
aValue = document.myForm.elements[i].value;

it gives me 100% CPU for a long time before i submit the form.

Loop Through All Unique Names On A Form?

Sep 13, 2011

I've got about 40 check-boxes on my 1 form. These check-boxes all have names (obviously) but they are NOT all unique names. The number of UNIQUE names on my form is probably around 8 or 9 (the actual number is NOT important). Because some check-boxes use the same names as other. It's set up this way, please don't ask me to change it, I can't change it.What's the syntax/method for looping through all the names? I was thinking I should do maybe a "for" loop;

for (var i = 0; i < fieldName.length; i++)

But I don't know how to hold a variable of the unique names to start with.

Loop For A Dynamically Generated Form

Jan 4, 2008

Here is the code:

function selectDefaults(buttonGroup){
for (i=0; i < buttonGroup.length; i++) {

if (buttonGroup[i].checked == true) {
for (count=1;count < document.addForm.recordCount.value; count++) {
var doc = document.addForm.feature1[i]
var featureVal = doc.value;
featureVal = featureVal.substring(0,2);
if ( featureVal == "SF"){
doc.checked = true}
} }}}

I need help in the second 'for' loop. Currently it is hard coded to replace the value of document.addForm.feature1 - but this field name is dynamically generated via the page it resides within. That being said, its name/id will increment depending on how large the recordset is. i.e. feature2, feature3, feature4 etc....

How do I get this to work in the javascript? I need to use this script to search all the 'feature#' fields in the form when the script is triggered. All I could think of was this: var doc = document.addForm.feature+count+[i]
which gives me a syntax error.

The purpose of this script, for those who will wish to know, is to automatically select all the features of the product that have the text "SF" (standard feature) in their value.

Creating A For Loop To Detect How Many Selects Are On Form

Jul 23, 2005

On my form i have multiple select which all have an id value total1, total2,
total3 etc so i am trying to detect how many there are and then use this to
caculate a total.

Is there a javascript reference to basically go to a form and produce a loop
which will show me how many select drop down boxes there on a form.

Or would i have t use something like

for (var i=0; i < frm.elements.length; ++i) {
form.elements.length
form_field = frm.elements[i]

and then have a nested if to detect if it is select value or has an matching
value ..

JQuery :: Form Validation On Submit - Endless Loop?

Feb 15, 2010

I have a form on my page, which I want to validate on submit. The code looks something like this:

$('#form').submit(function(){ if ($('#field1').length == 4 && $('#field2').length == 3) {
$.ajax({
url: someAjaxUrl,
dataType: 'html',
type: 'get',
success: function(html){ if (html != '') {
//show error
} else {
//submit form
}}});
} else {
//show other error
} return false;
});

Now, if I try to use
$('#form').submit();
In the else statement within the success function, the validation keeps getting triggered in an endless loop.

But if I use
document.form.submit();
- or document.getElementById('kbaFormSearch').submit(); -
The form gets submitted correctly. Is this because the anonymous callback function within the earlier defined
$('#form).submit()
gets triggered again? And if so, is there a way to get this to work without using "native JS" (not that I'm against it, but it would not make much sense to me unless there is no other way).

For Loop - Execute Function() When Submit Button Within Form Has Been Pressed?

Oct 18, 2009

[Code]...

1. What is the benifit of having the above code with "window.onload" and "for loop" and loop through the forms if I only have ONE form in html?

2. What is this line of code "document.forms[i].onsubmit" saying? Does it mean "Execute function() when submit button within form[i] has been pressed?"

3. function() - Does this empty function mean "run every following function below"??

Recursive Function With For Loop, For Loop Is Breaking When Calling Itself

Jan 22, 2011

I have been looking at this code for two evenings now, and rewrote it 4 times already. It started out as jQuery code and now it's just concatenating strings together.

What I'm trying to do: Build a menu/outline using unordered lists from a multidimensional array.

What is happening: Inside the buildMenuHTML function, if I call buildMenuHTML, the for loop only happens once (i.e. only for 'i' having a value of '0'.) If I comment out the call to itself, it goes through the for loop all 3 times, but obviously the submenus are not created.

Here is the test object:

test = [
{
"name" : "Menu 1",
"url" : "menu1.html",
"submenu" : [

[Code].....

'Menu 2' and 'Menu 3' don't show up! I'm sure it's something small that I'm overlooking.

Send A Loop Variable (i) To A Function Inside The Loop

Aug 4, 2011

I'm looking to send a loop variable (i) to a function inside the loop, but I can't seem to get it to use the value I want, it keeps making it a reference of i and therefore the function is always called using the last value of i rather than the one it was set with.

So if i have 5 Tabs then Tab 1, when clicked, should call DefaultTabClick(0) and so on rather than always using 4 for any of the tabs.
