Get Form Data Befor Submit - Populate A Simple Table With A Few Text Boxes In There
Oct 25, 2011
Im working on a backend panel where i populate a simple table with a few text boxes in there so they can update some values. I also have at the end of every row in the table an Edit, Delete & Save button. When i hit the save button i would like to update that entry in the database.
My Problem is that i need a value from the table before hitting a submit button, and the element names are dynamically created meaning ill likely need a variable sent from php to javascript and once i have the value in javascript ill need to send it back over to the php to manipulate and send to the server.
From wat i can gather using 'document.form.element.value' is the best way to go, hence why i posted this in javascript when most of my code is php.

Below is the code I use to populate a textboxes (compaddress) when I select the compname from the dropdown. I would like to be able to populate other textboxes such as the compdescription, compmaincontact and others when I select the compname from the dropdown. I think that I need an array but I really would like some advice on how to do it as all of my attempts have failed so far
Code:
<script type="text/javascript">
function showname(what)
{
what.form.textfield.value=what.options[what.selectedIndex].title
}
window.onload=function() {
showname(document.form1.number)
}
[Code]...

I was trying to create JavaScript error handling for a form, and I was trying to get an error message to show up underneath the field where there was an error. (I am trying to avoid alert boxes.) I only have two fields, and my problem is that only one field is showing an error message. If I place an error in the input for the second field, the error shows up under the first field. How can I get the error messages to show up under the correct form field?
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "[URL]">
<html xmlns="[URL]">
<head>
<meta http-equiv="Content-type" content="text/html;charset=UTF-8" />
<title>Carrots</title>
<style>
.qty {
width: 25px;
text-align: right;
}.blank {
display: none;
} .....

I have 4 text boxes that are supposed to load 4 seperate values of data from one field in one table from a database. The field is called interface_cropsettings (from the interface table) and these values have been concatenated and comma seperated in this field.
Code:
Once the form is filled out and saved, the data is inserted into the database and the values from these 4 text boxes are concatenated, comma seperated and inserted into that one field correctly.
(Example)
If the 4 text boxes have the following values:
In the database field they become:
However, if the form is closed and then re-opened, each text box displays the entire database field rather then each value seperated in the corresponding text box.
(Example)
All 4 text boxes display this:
I already know why the data appears like this in the form, my problem is that I'm not sure how to write the javascript to seperate the values into the correct corresponding fields, assuming javascript is what I should be using!
Also, this is kind of irrelevant but just in case you're wondering, this form is part of a cold fusion application!

I have a page that runs a lot of calculations.The math is computed on the fly using java scriptwhen all the calcs are in, prior to form submission the user needs to evaluate which numbers they prefer, and from there, once they select them, the form, based on those choices, will perform one last calclets say we have 3 result fields
r1 = 2000
r2 = 3000
r3 = 4000
what i want to do is have a select field be able to display those values at the bottom of the page;for example
<select name="s1">
<option value=[field contents of r1 above]>[field contents of r1 above]</option>
<option value=[field contents of r2 above]>[field contents of r2 above]</option>

I am developing a web application in java (jsp's and servlets). For the project I am working on I will need to develop an html data entry screen and the code to load data into the screen, and then save the data back to the back-end database.
How to do the following:
Read the data out of the database (JDBC, no problem) in a servlet.
Put the data into the appropriate form for returning to the data entry screen, which will be a jsp. (Is JSON the right choice for passing the data from the servlet to the jsp?)
In the jsp, parse the returned data and populate the HTML form elements (text fields and combo boxes). When a button is clicked, pull the data out of the form elements and return to a servlet for saving back in the database.

I'm a CSS and PHP developer, finding myself using jquery and AJAX more and more, of course, and learning a little about it as i go. but only a little. :o)i have a client who's asked me to add an image upload feature to a simple comments post script i've "built". i can see, kind of, how this jquery is posting the form text inputs, but have no idea if this thing can even be made to post a file at the same time.Hoping someone might add a function for me to do this if it can be done?
$(document).ready(function(){
/* The following code is executed once the DOM is loaded */
/* This flag will prevent multiple comment submits: */

Let me start out by saying that this is for a small-time page with absolutely zero valuable information. PHP or server-side is way beyond the scope of my goals for the project.
Basically, I have a form on a page which I want to use to submit a password. However, I have realized that using the form submit always makes the browser return to the page with the form.
Well, that's not good when I want to redirect using javascript!
My javascript is:
Code:
My form HTML is:
Code:
How can I get this to stop going back to the page with the form after I submit it?

I have a product select page that is really slow to use because 6 dropdowns must be populated and the page reloads after selecting each box, to get the options for the next box.I want to speed it up as follows:
1) User selects one of 50 products from a dropdown list.
2) Page reloads, and all the possible options for the remaining 5 dropdown boxes are now populated (ie. list options all stored client side)
3) User can freely input the remaining 5 dropdowns without the page reloading.

I've been ask to produce a new upload form that can allow multiple files to be uploaded with each article i was thinking of adding an upload form field than when text is added to the text field an extra file name description and upload text box would appear on the page via javascript.
So the more files that add to the form the more dynamically produced form text boxes are added, i have been looking to find if this could be done or what way is better, if anyone could help with telling where to look or how to dynamically produce more text areas. Or could you let me know another solutions to this.
I have seen it work on my mobile when added new contacts, you type in mobile number and then the home text box appears below it, then you type in home number and then the work text box appears. etc..

I'm getting an incredible behaviour of internet explorer.
I have a generated html page with one form and many input of checkbox
type.
Those checkbox are grouped in 4 lists and each list of checkbox
contain checkboxs with the same name so I can easily retrieve on my
server side (java) wich checkbox are checked with a
request.getParameterValues(). (Each checkbox has a value corresponding
to the id of the row)
Anyway that's not on the server that the problem is.
Here it comes. When more than 132 checkboxes are checked, my form
submit generate a javascript error. When 132 or less checkboxes are
checked it submit without problem.
I tested the page with firefox, the problem is not here with that
browser and it can submit liek for example 400 checkboxes.
Then I tried to make a workaround, on submiting I browse the elements
list of my document and I create a big string containing all the ids
checked and then I uncheck all checkboxes and submit. there again it
fail to work.
I'm really affraid I'm looking at a nasty bug of Internet explorer
here and I'm going to engineer a more deep workaround if noone can
point out a solution to me.
I should precise that I have no iframes on that page. I indeed saw
that some people got 'access is denied' on submit form but in my case
it works when not too much data is going to be submited !

Been racking my brain all day trying to figure out how to duplicate this code with the limited javascript knowledge I have been trying to learn.This code is a Dropdown menu of Yes or No, than a Select button that Opens up a Text Input directly below the dropdown. So far, It works great. My problem is I need at least two of these on the same page and I do not know how to go about it. I have tried changing values to accommodate adding another on the same form, but than both stop working.
