JQuery :: Dynamically Add And Remove Form Elements?
Aug 21, 2011
I am trying to insert and remove form element dynamically. What I was doing was some sort of recipe program where a user can prefer to add for elements as he/she is done inputting a recipe. He/She can also remove the ingredient if he/she opts to. Here is the link: [URL]
I already solved the problem but I am not sure if what I did is an efficient one. The thing I did was clone the first child of the form. But I realized that if I would put text inside the first child of the for, the duplicate field will also contain the same text as the first child which I don't want to happen. This is why, I set the display of the first child of the form as none. I am not sure if this would cause some problem when I would submit the whole form so that the inputs will be saved in the database since the first child is empty. I was thinking that as the form will be submitted, I would just remove the first child.

I have a function that dynamically creates page (form) elements with the option to remove it.
Code:
divcounter++;
var element = document.createElement("input");
...
element.onclick = function() {removeElement('sel' + String(divcounter))};
[Code]...
For some reason divNum in removeElement() always returns the latest value of divcounter. So if I add 4 form elements, and I want to remove the 2nd item, item 4 is removed and above fuction returns an error when I want to remove another element afterwards because it is trying to remove the 4th element again.

When the user select an option in a dropdownlist, new dropdownlist elements are added dynamically using jquery. When a user clicks on a new option i the first dropdown, I want all the dynamically added events to be removed so that I can render new ones. But it seems the dynamically added events haven't been added to the DOM, so they cannot be removed. Is it possible to remove them? In that case, how? I've read a lot about .Live(), but my problem is not regarding an event - I just need to reach an element(?).

So I have a table with rows and basically I cloned it and then appended it underneath another table. The user can click on the plus button to clone the table (which on the UI looks just like a row of fields) over and over. Next to the plus button I have a minus button that I want to use to remove the cloned table. Here's my code for the add table button:
Basically what I need to do is write functionality for the remove button that when clicked removes the bottom most table. Is there functionality in jquery where you can say "find last occurrence of 'addrow' and remove it onclick"? [code]...

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 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.

I have form that asks a simple question: "How many XYZs do you want to create?" Then, for every XYZ, it should create several new labels/inputs in the form.
That is, every XYZ looks like this:
<div id="xyz">
<label>Whatever</label>
<input> blah blah blah </input
</div>
I looked into .each() and .live(), but I can't wrap my mind around how to do this.

It works perfectly but I need to add more fields than stated in the post. If I add in another field, only one field gets the increment. The other doesn't. Eg.
<form id="myForm" method="get" action="test.php">
<div id="input1" style="margin-bottom:4px;" class="clonedInput">
Name: <input type="text" name="name1">
Tel: <input type="text" name="tel1">
</div>

I am currently working on a site as part of a student work term. One of the features of this site is the ability to upload a resume. The resume can have a arbitrary number of "work experiences". I have set up a form and want the user to be able to add new input elements with a click of a button. Here is a very pared down(for simplicity) version of the form:

I have an entry form where a length needs to me entered. It can either be entered in meters (one input field) or feet and inches (two input fields).
I'd like to have the user select which units he wants to specify (with a selection tool) and then the form would automatically either display one text box or two.

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;

The code below will add new form elements when ever I click the add button. However when you add more elements the combo box element goes out of alignment.
multientry.js
function addValue(divname){
var newdiv = document.createElement('div');
newdiv.innerHTML = "<BR><INPUT TYPE='text' name='index1'>";

Is this something that is better suited for Javascript/DHTML or AJAX? I have not been able to find any tutorials on how to do this. Can anyone give any suggestions? I am very new to both Javascript, and of course AJAX, since with out Javascript there is no AJAX.

I have a page I am working and I am having some trouble with: I need to show and hide areas based on a radio selection. I initally started using the show / hide feature in Jquery but the problem is the elements need to be removed but then put back if the user selects the radio buttonagain as it has form elements that have validaion on them. The validation is still trying to validate the form elements becuase they are still on the page but just not showing. This is the radio group the user makes the selection from:
<input name="terms_usr" type="radio" id="terms_usr_1" value="1"/>
<label for="terms_usr_1">Credit Card</label>
<input type="radio" name="terms_usr" id="terms_usr_2" value="2"/>
<label for="terms_usr_2">C.O.D</label>

I'm created a set amount of dynamic elements based on some elements in another form to try to submit them when the current form is submitted and this just doesnt work. It creates all the elements succesfully and puts in their proper names and values, but on the next page they are not available in $_POST in php.Here's the exact javascript I'm using, I tried appendChild and innerHTML,
Code:
var elem = document.getElementById('submission_options').elements;
for(var k = 0; k < elem.length; k++)

Im using a JavaScript function to dynamically add rows of user-input data to a form, but Im having problems getting it to work properly with Firefox (works well in IE, though). We are using Struts 1.3 and JSPs, if that makes a difference.
The JavaScript function seems to work initially because the newly added row will show up on the JSP after the user enters their data and clicks a button that uses an onclick event to call the function. However, when I submit the form the new elements dont get included in the request. The result is that when I use the following code in my Struts Action Class to get all the parameter names submitted in the request, I dont receive the new form elements that were added by the JavaScript function and I cant process those newly added records:
Enumeration e = request.getParameterNames();
Here is the JavaScript code for the function that I call to dynamically add rows of data to the form.
function addData(tableId, distBedsCode, empCode, fte) {
var tbl = document.getElementById(tableId);
//grab how many rows are in the table
var lastRow = tbl.rows.length;
[Code].....
Ive tried using hiddenElem.setAttribute(name,) at the end of the above code, instead of something like hiddenElem.name = , but that didnt work. There is just some difference between the way Firefox handles things and the way IE handles them

I'm trying to allow users to add the text from a text input into a list, and then have the option of removing this list item. So far I have the code below which allows me to add a styled list item with a link in it which I would like to close the box when clicked but at the moment when I click it nothing is happening. I'm not sure if I'm approaching it correctly or if there is an error in my code.
jQuery(function(){
$('#addTask').click(function() {
var Task = $("#jobTasks").val();
if (Task == '') {
[Code].....
