Retrieving Value Of Dynamically Generated Form Fields In Firefox?
Mar 1, 2009
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();
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.
There can be any number of 'groups' but I would want to apply some validation for each item in a group. I can only see that the validation is done by specifying a id? however as the id's are going to be dynamically created how can I do this? can you validate for a css class?
I am working on an MLA citation PHP script for books, and I already finished that part. I have the page set up so that the user may add as many authors as needed. However, when I use the back button, I notice that if I have more than one author, the dynamic text fields are gone and all data after the dynamic text fields are not loaded back into the proper fields.I've spent the entire day searching for solutions, and I tried saving the code to a textarea, then using that code to insert it back into the page on loading. However, I couldn't get it to work.[code]
I'm having a problem with the page at http://www.bathfringe.co.uk/contributors2011_2.php The user is able to add new performances to the form. This functionality is provided by cloning elementsPart of the code should add a 'counter' array key to the names of the cloned form inputs (full code obviously available at the page linked above):
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.
And I doing some validation like this. function checkvalue() { var f = document.forms['formA']; var eLen = f.elements.length; for (var i=0; i<eLen; i++) { if(f.elements[i].name == "text_" + i) { alert ( f.elements[i].name); } else { alert (f.elements[i].name); } }
It never goes into first part of if statement.. Is there a way I can access these kind form elements..
Is there a way to access a form element that was created using AJAX?I've had no luck when using 'document.getElementById( elementID )' as the element doesn't appear to be recognised.
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?
I am trying to write a Greasemonkey script using jQuery to automate various processes on a web site. One of them involves automatically filling in a form located in a dynamically generated iframe. When the frame is generated I can do $('#NewFrame').length and get 1 confirming it is now available. However, when I do $('#NewFrame #TheForm').length I always get 0 even though I can clearly see the form there in the iframe.
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.
At this point I have been able to add the row. But what I want to do and am having trouble with is alternating the row colour to the dynamically added row element.
Sample of code I am using:
Code: var tbody = document.getElementById('tableItems');
var td1 = document.createElement("td"); td1.appendChild(document.createTextNode(qty)); td1.setAttribute("class","qty"); row.appendChild(td1); tbody.appendChild(row); One thing that puzzles me, is that even after adding a row the table my table.rows.length still = 0.
Does anyone know how I can determine the appropriate amount of rows so that I can apply the appropriate class?
Or is there just something blatantly wrong in my approach?
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" />"; $(this).before(new_field); });});
As you can see I create the field using javascript and just insert it before the add field button. However I have seen lots of other sites have a smiler sort of function but they seem to make an ajax call for the field as they use a loading-type animation during the few seconds it takes for the field to be added. My questions are : Which is a better way of doing this type of thing? And why is one better than the other? If it is better to create the field client-side should I change how I am doing it? Instead of creating a string representing html and appending it should I be doing it a different way?
Below is the html and js I have so far to dynamically place form fields on the form when a certain radio button is marked (Fixed hours). Problem is I can't get the fields to go away if the other radio button is marked (Variable hours). Solutions on what code my js needs to remove the fields when the opposite radio button is marked?
I have a form with 3 fields that will allow a user to search a database of clients by either name, email, or client id number. However, I would like the user to only be able to put information in one field. It can be done be either deleting the other two fields when the user inputs information into a different field, or by disabling the other two fields when the user enters information in one (and also frees up all fields if the user ends up deleting what they entered).
Below is a start of what I had. Basically, it will disable the fields when I mouse out of them but won't re-enable them when I mouse back in. As you can see, I tried various combinations of events. (My code below also doesnt null out the other fields when the user opts to use a different field than the one they first began to enter info in).
<html> <head> <script type="text/javascript"> function makeDisable($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?
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.
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 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)
If I try to access the value of this dynamically generated field (i.e. $("#field").val()), I don't have any value returned. I understand this may be because jquery doesn't detect it as being a part of the DOM or something along those lines.
We are facing a problem with alt attribute in Java script. While retrieving alt attribute in IE its working fine but in FireFox we are getting as undefined. How to retrieve the alt attribute in firefox.
Please find the below code for how I am retrieving... <html> <head> <script type="text/javascript"> window.onload = function(){ var els= document.forms[0].elements; var compcode =""; for(var i= 0; i < els.length; i++){ if (els[i].id!="") { alert(els[i].id); alert(els[i].title); alert(els[i].alt); }}}
</script> </head> <form action="#"> <select name="test" id="testing" alt="test|001" title="test|ddd"> </select> </form> </html> The above code is working fine in IE but not in firefox.
I spent several hours struggling with dynamic form fields added with appendChild or innerHTML not POSTing on submit in Firefox. The only way I found to make it work is to append any created fields to a DIV within the form. Code:
