Jquery :: Altering Dynamically Created Form Fields ?
Mar 3, 2011
The link below is a stripped down section of a form.
[url]
The problem I'm having is with altering the names of the fields. I'm trying to add an identifier on the end. "_X_1", "_X_2" after the new sections are added.
NOTES:
Incidentally, "_X_" is a delimiter so the key can be converted into an array on the back end to extract data from it.
I can't alter the "repeater" variable because it would be extremely complicated on the back end.
I want to give the user the abillity to add extra fields as needed. I've got it working in IE (surprsingly this works in IE but not in Firefox), however, basically I have an input field for a paragraph. If the user decides they want two paragraps then they can click an image and a new textarea field is show that allows them to add another paragraph. The fields are named as an array for example name="para[0]" the next one would then be name="para[1]". Firefox creates the field and shows it to the user however when you submit the form the new field does not come through. My array of paragraphs consists only of the original number I started with. Any added by the javascript are lost. Again IE this works fine, Firefox it works till you submit the form. Any ideas?
var inputCounter = 0; function addInput(divName){ var newdiv = document.createElement('div');
[Code].....
was working perfectly, until i did some minor changes to the script that was not even related to that part of the script, and it now shows Notice: Undefined index: f1 in C:Apache2.2htdocs sindex.php on line xxx meaning that the data is not set anymore. everything else is working perfectly. the fields are still added as before, but the data does not post. what might cause this not to work all of a sudden?
As you can see in the "action" attribute, I'm calling this function:
function SubmitEditedInvoice(invno) { $.post('output.php?mode=6&invno=' + invno, $('#formEditInvoice' + invno).serialize(), function(output){[code]....
The problem I'm having is that no data is passed to the PHP back end. I have verified that the variable invno is correctly passed to the javascript function, and have tested my .serialize() by using a hard-coded form ID, but I still get no data passed through.
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 site I am working on has a few forms that allow the user to add new form fields (textbox, textarea, etc.) dynamically. I am using a structure smiler to: <form> <label>Name : </label> <input type = "text" / > <label>Age : </label> <input type = "text" /> <span id = "add_field"> Add Field </span> </form>
<script type = "text/javascript"> $(function(){ //create a new field then append it before the add field button $("#add_field").click(function(){ var new_field = " <label>Name : </label> <input type = "text" / >"; new_field+="<label>Age : </label> <input type = "text" />"; $(this).before(new_field); });});
As you can see I create the field using javascript and just insert it before the add field button. However I have seen lots of other sites have a smiler sort of function but they seem to make an ajax call for the field as they use a loading-type animation during the few seconds it takes for the field to be added. My questions are : Which is a better way of doing this type of thing? And why is one better than the other? If it is better to create the field client-side should I change how I am doing it? Instead of creating a string representing html and appending it should I be doing it a different way?
I am using a combination of php and Javascript to create forms that allow users to edit entries from a MySQL db.[code]The problem is that the form is not submitting. I think it has to do with the fact that the input fields are created dynamically.
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++) {[code].....
I want to be able to access whatever the user types into my testCreation.html in a session created in testCheck.php. I then want that session to be accessed by testView.php. code...
what I am exactly trying to do is get data from a form, push that data into an array of objects and when a "display" button is clicked, to display the data in the form a div layer with a table in it for each object created. I have problems with dynamically creating the divs. Here's my code
My requirement is to submit html form with Attachment filesfor a web based email application.I have used javascript to achieve Attach more files functionality.When user clicks on ttach more files link, following HTML is dynamically generated using javascript:
<input type=file name=some_namesize=/>
The Javascript code is:
function addRow(tableID) { var table = document.getElementById(tableID); var rowCount = table.rows.length;
I'm having some trouble with my dynamically generated form fields.
As you can see I'm generating new form fields, but the problem lies within the grade field. I have it set up now so that when you change the grade the color of the <select> box changes relative to the grade. A-D are green, F is black with white text, Not Taken is just regular white with black text and In Progress is lightly shaded grey.
I want it so that each one can be changed individually, but I can't seem to be able to figure out how to do that. Heck if you change the first one's grade field, that colour follows the rest of the clones.
This is the jQuery I'm using to change the color of the thing.
I am not new to jQuery but I just want to ask the best way to approach this. Basically I have a textfield in which the user is going to type in a number (for example 20) and after this textfield lose focus jQuery will be triggered to create whatever number of textfields the user put before (in this case 20).
So, to illustrate: How many users do you have: [ 2 ](and after the field above lose focus, the below will be generated)
I created a form that contains about 10 form fields and would like to add the option to dynamically add more sets of those 10 fields if a user clicks a word or a button but I need help. I'm a beginner when it comes to JavaScript. This is what I need to generate dynamically.
I need to make a form in which I have to enter upto 20 email addresses. But I want to show only 5 fields first and then an Add More button. Upon pressing the Add More button it should add another field into the form and displayed. I have seen this type of thing on several websites but don't know how to do it.
Below is the html and js I have so far to dynamically place form fields on the form when a certain radio button is marked (Fixed hours). Problem is I can't get the fields to go away if the other radio button is marked (Variable hours). Solutions on what code my js needs to remove the fields when the opposite radio button is marked?
I have a form with 3 fields that will allow a user to search a database of clients by either name, email, or client id number. However, I would like the user to only be able to put information in one field. It can be done be either deleting the other two fields when the user inputs information into a different field, or by disabling the other two fields when the user enters information in one (and also frees up all fields if the user ends up deleting what they entered).
Below is a start of what I had. Basically, it will disable the fields when I mouse out of them but won't re-enable them when I mouse back in. As you can see, I tried various combinations of events. (My code below also doesnt null out the other fields when the user opts to use a different field than the one they first began to enter info in).
<html> <head> <script type="text/javascript"> function makeDisable($ID){ var x=document.getElementById($ID)
My client wants to upload multiple files to the server using the FILE type input of the form. Their requirement says that once they click the browse button of the FILE INPUT type , besides file browsing window another FILE FIELD is added at the bottom of this one. and when the user clicks the browse button of second, it adds another until the user clicks the UPLOAD button to submit the form.
I dont know it is possible or not ???? if yes then please tell me how.
The alternate way is to give drop down menu with number and when the USER chooses certain number then ..that amount of FILE FORM FIELDS will be added. i.e if user chooses 3 then three file fields are there to upload 3 files at a time.
I have written a script that i am pasting here, but when i choose the drop down menu and select value the FILE FIELDS are shown but the original drop down menu vanishes.. Please review my code and modify it or refer some script to me.
IF The first choice is possible, i mean adding each FILED by browse button click , then tell me its code, other wise modify this code that i am pasting or give me some link to download a premade script. Code:
I am trying to assign values to a bunch of form fields. However, I don't want to loop through EVERY field in the form, just a specific subset of fields. The fields I am trying to change are all named similarly myField1, myField2, myField3.So, my thought is that I would like to use a for loop and loop through the appropriate fields by simply incrementing a variable and appending it to the end of the string "myField" in order to change the appropriate field.How can I evaluate "myField + iterator" into a useable reference to change the value of said field?
So, I have a form that, when the user clicks on a link, uses J/S to generate extra form fields for extra information. I can retrieve the value of the dynamically generated fields using $_POST in I.E., but it doesn't work in Firefox (no value is returned). Retrieving values for the static fields is fine in both I.E. and Firefox.
Here's the code - is there a function I'm using that could be replaced with something more friendly to Firefox?:
<script type='text/javascript'> var i = 1; function addArea() { var newArea = addElement();
Currently, I have a php form with various inputs, and a div where I am embedding an (initially) empty open flash chart object.Right now, I am calling a php file on the submit of the form, which takes the form data, calls a python script to process the form data, and then creates an open flash chart object using the data the python script returns.There are a few problems with this:
1. When the submit on the form is called, it goes to a different page where the chart is displayed, when I would really just like to update the contents of the chart div where I initially embedded the empty chart.
2. The processing of the form in the python code can take some time, so what I would really like is to have the chart "check" the output of the python script periodically and update the chart each time, adding the new data points to the old ones.
I know I can do all of these things with javascript and Ajax, I just can't seem to find any tutorials or examples that are exactly what I am looking for.
i have created one simple login form with 5 fields namely username,email id,password,retype password and phone no.i have created alert message for each function,so that when there is an error it displays alert message..now i have to replace all alert messages with inline validation(displays errors beside textbox).
I dynamically create a textbox as follows, but I cannot retrieve the value entered by the user:
bp_boards = ' <tr id="hwNumberBoards"> <td>No. of modules:</td>[code]....
The dynamically created textbox shows up on the page but after the user enters a value, I cannot retrieve it from jquery(alert ($("#hwNumberBoards").val()) is "undefined")
I am creating Textboxes at Runtime with something like this code...
and what this function does it count the number of Characters that have been typed in a Textbox. so i am displaying the remaining characters. So that is working fine on my example because the Element is known at Early Binding. Now my question is what if the textbox is created dynamically ?
contentbox
this is the name of the Textbox in my example.
how do we use a J Query in Dynamically created Textbox.
