View 1 RepliesI want to do something like the following pseudo:
For all elements in the body tree - if they have text in them - check if the text equals "the", and if so, replace it with THE.
how to write such a selector?
Here is a list of block-level elements: [URL]. What is the best way to detect these using JavaScript?
View 5 Replies View RelatedI'm performing some validation functions on a form I've created.For the phone number, I have 3 text boxes lined up next to one another. The first is for the country code, the second is for area code and the third is for the remainder of the phone number.I have used the following in order to detect whether the input value isNaN.
Code:
input = document.getElementById("phone1");
if (isNaN(input.value)) {
errorText += "[code]...
As I have three text boxes for the phone number, can I group them within this one statement? So, ...getElementById("phone1, phone2, phone3"); ?If not, what would you recommend?
I'm looking for a way to detect form change in jQuery. For exemple Idisplay a big and dynamic form pre-filled with values and splitted intabs.I would like that when some form values in a tab is changed an iconappears showing that a save is needed. I also would like to have analert if the user click on the menu without saving.Is there an existing plugin or has someone already done this kind ofthings ?

[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 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+"'/>"};
$("#list1").addRowData(boxNo,myRow);
I'm using the jquery plugin found here. I love the look but I have a form that uses functions like this:
[Code]..
So, when you select a country and it retrieves the state/province text input, the jquery css is not applied to it. Is there something I need to add to the code above or to the jquery initialization code here:

Is there a way for a JS script to detect the number of the form in which the script resides?
(i.e. document.forms[0]/[1]/[2] etc)
So:
<form action="somewhere.php" method="post">
<script>alert(//num of this form//);</script>
<input type="text" name="myfield">
<input type="submit" value="go!">
</form>
What i'm trying to do is pretty simple. I want to detect if the value of a field in a form called "check" and if the value is "1" return the user to a different page. i also want it so if the value is anything else the user is returned to the homepage. Here's what i have so far:
[Code]....
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 ..
I have multiple submit buttons in a form, with the same name. ie code...
Is it possible to detect which submit button was presed, from within the onsubmit handler for the form, or would I need to apply onclick handlers for each button, and submit the form as part of the function?
I'm submitting a form (cross-domain) to an iframe and want the parent to close after submission. How can I detect if the iframe is loaded?
View 1 Replies View RelatedI have a form that is pretty large, so to break it up I hide certain fields unless the information is required.
The problem is this. Lets say that I select that I a have a dog, put in some information in the newly shown fields, and then decide I don't want to say that I have a dog. If I select no to the dog question (the radio button that shows or hides the fields) the information I entered is still there. I need the information in those fields to be cleared when the fields are hidden.
this is the structure of my current HTMl [code]...
If the person says the have a dog, then all fields with class .dog_hidden will be shown, otherwise they are hidden. How can I select all form field types contained within a div of class="dog_hidden" and clear there value (either reset or set to an empty string " ") .
The goal is that every time the fields are hidden they need to be cleared or zeroed. Its important that this information never get put into the database (all fields with a value will be entered).
I want to show or hide some tags of registration form with changing a combo
I wrote this code :
$('select[name=user_type]').change(function(){
FormType = $('select[name=user_type]').val();
switch (FormType)
{
case 'teacher': $('.teacher_form').show();

How to dynamically add form elements using jquery?
Attached is a screenshot of what I am doing.
how to reference a specific form element within a page with multiple forms and common element names, example below.
<form id="Form1">
<input id="UserID">
</form>
[Code]....
I thought something like this would work, but I can't get it to work.
$("#Form2.UserID").change();
I have a form that has it's HTML inserted into the database (yeah yeahI know..not my idea..I'm new here and just finding this out).Anyway, each form field has an embedded class in the HTML.The form is dynamically generated. Can be anywhere from 5 to 10 to 20to 50 fields.How can I loop over each form field and add a new class to the field
View 8 Replies View RelatedI'm relatively new to JavaScript. I would like to loop through all the elements within a form and grab their values and what type of input they are. So far I came up with:
[Code]...
I have a FORM with many elements, and some of them have names like "name1[]", "name2[]", etc..
I would like to create a button that, once clicked, will clone all the elements whose names end in "[]" (including labels, and select's options), giving them the same name (and possibly a different ID, but it's not important).
I am completely new to jQuery and almost new to javascript.
I came up with this code to clone the entire form:
<script type="text/javascript">
$(function(){
$('input.cloneMe').live('click',function(){
var f=$(this).closest('form').clone(true);
[Code]....
But how can i tell him to only clone the elements whose name ends in '[]' ?
i need to us instead of closest, but i really don't know what.
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.
[Code]....
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"
View 1 Replies View RelatedDoes "document.formName.elementName.disable" work on hidden form text
elements? I have a form with some input fields that are associated with
some hidden text fields and I would like to disable all of the
categories inside the form when the page loads and only enable each
category as it is needed. Code:
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.
Here is the javascript:
Code:
function add3<%=strGoalCount%><%=strObjCount%>() {
var foo = document.getElementById('fooBar<%=strGoalCount%><%=strObjCount%>');
var numi = document.getElementById('theValue');
var num = (document.getElementById('theValue').value -1)+ 2;

I'm building a custom component in Joomla. All the Jquery up till now is working just fine.
I'm not sure if I'm using the wrong keywords or what, but I'm not having much success finding a way to make the following happen:
I have a form that asks for a bunch of information. First it's name, etc... Then it asks for vehicle information: The code for that is this:
<table class="rsmformtable contentpaneopen">
<tr>
<td colspan="2">
<div class="rsmformtablediv">
[Code].....
So, what I want to happen is that there is an add vehicle link or button so that when someone hits it, it allows them to add in another vehicle. Of course it should also add some index to the id's of all the inputs as I will use the post data to add the vehicles to a database.
Now at first I thought I had found a solution, that works a little bit. But then when the PHP comes into effect things break.
Also, this is an aside: the truck vin row is controlled by jquery now. If the plan type selected is for a truck, it will show that row, if it's not then that row is hidden. I'm pretty sure I'll need to build a loop in the Jquery script that will allow that hide and show feature to work based on the index added to the truck row.
in my searching, the only thing I've really been able to find is that I might have to use AJAX, but that's not something I familiar with just yet.
Is it possible to duplicate a few form elements on click of a button? For example if we have a form with the following fields:
1. Name
2. Address
and we have a button that says add a member
on clicking of which the same two fields above should be added:
1. Name
2. Address
