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.

how to add extra properties to html elements as I was storing data in html attributes. After looking at some others code including Raphael and this addEvent code. [URL] They seem to treat objects just like an array. obj[property] = value; This would have been extremely helpful to know previously as I have needed to be able to include variables in property names - but have resorted to making the whole thing a string and calling exec() on it.
View 2 Replies View RelatedHow 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.
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?
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?
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.
View 2 Replies View RelatedI 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.
I have 1 form, and dozens of elements. In the select elements I use onchange="somefunc()". In this function I'd like to access and change the form element attributes (such as form.element.option[].value and form.element.option[].innerHTML).
Is there a way to access the element that has just changed (unsing onchange="somefunc()") by passing a "this.element" parameter to access the elements properties such as form.element.option[].value within the function?
Anyone have an online list of properties that can be changed?
In particular, I'm looking to change the properties of a textbox in a form. E.g. Border colour & background colour.
This bit of code allows me to change the text that is initially in the text box (before a user starts to type).
Code:
document.myForm.tboxMsg.value="New Value";
<form name="myForm">
<input type="text" name="tboxMsg" value="Old Value">
</form>
The question is - what else can I change & is there a big list somewhere?
My use of the word "properties" and maybe others may be incorrect...Apologies in advance, I really don't know much about javascript.
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?
View 7 Replies View RelatedI've been struggling trying to get a small order form to work the way I want it to. Here is a link to the live page: [URL] And here is the code in question:
[Code]...
I have two questions...
Question 1 How can I make this piece of script act a little smarter. Look at the order form, I'm catering for up to 4 people and providing lunch for them. If they select 3 people and the spaghetti bol for lunch, it's only adding $10 where it should be adding $30. Obviously this is simple multiplication but since the values in my form are prices it makes it a little tricky. I'm guessing an onselect on the first part of the form which changes the pricing of the other items would be the way to go, but how do I do this?
Question 2 The "Total Price" is placed before the <form> tag by the script. This is ok but it's not where I want it. How can I position this text elsewhere in the document?
I need to pass user input from a form to one database field. I'm relatively new to JS but the idea I had was to have several form elements and use JS to collect the users input and send all the values through a hidden element. What's happening is the variable names are being sent rather than the values. The code below is only passing to the next page. Limitations: I am editing an intranet site built by a 3rd party so a lot of the files we've been given are encrypted. I cannot change the method to post.

I've put together what I think is an illustration of my problem at [URL] Quite simply, I need to be able to access the elements of the form without referring to them by ID as the whole form is intended to be cloned. I intended to do this using parentNode and childNodes[] together with the 'this' keyword. My understanding of 'this' in this context is that it should refer to the HTML element calling the function, i.e. one of the radio button inputs. However this gives the error "Error: this.parentNode is undefined"

I have a grid that I'm adding rows to that include form text input boxes using addRowData. I know I can use the "editable:true" for that but I'd rather not at this time. Anyway I have the <div id=list1></div> surrounded by a <form></form>. Also statically I have a couple of text input boxes and a submit button. When I press the submit button the only parameters that show up in the POSTED data are the static ones. Is there a way to get the form elements "registered" with the form? I know I can always use javascript to extract the data and save it via an ajax call, but if there is a way to do it "correctly"
Example
var myRow = {id:"0",call:"<input name='callt"+boxNo+"' id='call"+boxNo+"' class='calls' type='text'/>",amount:"<input name='amt"+boxNo+"' id='amt"+boxNo+"' type='text' value='"+defaultDep+"'/>",residual:"",calculate:"<input type='button' class='buttons' id='b"+boxNo+"'/>"};

I'm working with a form that has both static and dynamic form elements (add textbox, etc), and while I can access the static elements via request.form, the dynamic elements cannot be accessed. I have the dynamic elements appended within a div that lies within a table.

How can I traverse through all elements' attributes and ids of a given form id ?
I'm creating a news section for a CMS in PHP and mySQL in which I have a text field for the headline and an textarea for the article. Instead of making the user add each article one-at-a-time I would like to know if there's a way to dynamically create/remove these elements with a button?
for instance; at page load the form contains 1 article - it has 1 text field and 1 textarea. The user decides that he wants to add 2 more articles, so he clicks the "add" button twice. Now the form has 3 articles (3 text fields and 3 textareas), each with a unique id (art1_head,art1_txt, art2_head,art2_txt, art3_head,art3_txt).
Then, I also need to have a button or checkbox to remove each article.
Forgive my ignorance. I'm not a js guy, I work in PHP. Is this possible?
I'm trying to modify a form so that when a user clicks a checkbox for a
shorter version of the form, it will replace swap the default (long)
form elements with the short version of elements, so that only the
version that is selected will have its element values passed on to the
next page. Code:
I have a form that contains around 20 input elements,
they have some onclick event on it.
I would like to know how can I get the form element index when the
onclick event fire.
I found no property or method to do so.
I need to loop through all form elements such as text, radios, check boxes and the like and to save their state in a file. does anyone have JS code to do this ?
View 1 Replies View RelatedI have a function which passes text from txtdebt to debtsbox which

i want to control the 'Enter' key to set focus to the next element in

that?
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?
