Can a OnChange event call a PHP function?
Currently an OnChange event on a listbox I want to pass the value (a path) to a PHP function.
Not sure if this can be done...
Currently I have captured the path... now I need to get the path into a PHP Function!
THIS WORKS:
<html><head><script type="text/javascript">
function recalc() {
alert ('Entering recalc().');
}
[Code]....
The first example works, which shows that the recalc function can be called. The second example works, which shows that onchange will trigger an alert box. BUT, the third example doesn't work. Why can't I trigger a call to the recalc function from the onchange event?
The above 3 code postings are the entire programs. Nothing has been left out or modified.
I am using IE 8.0.6001.18702.
I create some iputs using this code :
Code:
And i would like to call this function on the onchange.
function c(group,position){
I'm building a form in PHP. One of the fields needs to generate information based on another selected input. The first input is for "phase" and based on that I need to count how many entries there are in the database for that phase, then display posible positions(ie 1 per entry including the entry being edited/added). I know that this can't be done with only PHP.
I don't work with Javascript normally so I am struggling. I have read many similar topics, but can't find the answer I am looking for.
I thought that the solution could be to call an include file when a selection for phase is made, but I don't know how to pass the information to the PHP script.
I'd prefer not to have to reload the page or form.
Here's the code that I have so far:
Code:
<html>
<head>
<body>
<form action="edit-category.php?id=<?php echo $id; ?>" method="post"
[Code]....
I have a <div> like
<div id="test2">
Name : <input type="text" name="test3">
<select name="test4">
<option>A</option>
<option>B</option>
<option>C</option>
[Code]...

I want to call a method from java class using onchange in SELECT
View 5 Replies View Related<button onClick="return popup('<span onClick='selectShape(1, 1, 1)'>test<span>');" tabindex=Ɖ' onFocus="setFocusColor(0,3)">....</button>
This will work perfectly, but as soon as I need to pass Strings inside the selectShape function, I get stuck.
So the question is, how can I create the following and have it working
......selectShape(2, 'Tricky', ཤx5°').....
I'm currently facing a weird issue with the onchange event. I have a web application where each blur event makes a call the webserver to store the value of the textfield. I only want to trigger that ajax call when something has changed, so i track the onchange event on each textfield to set a flag if something has changed.
The onchange event always fires to first time when i click outside of a textfield even if i didn't change anything in the field.
I narrowed it down to the following: A prefilled textfield always fires the onchange-event the first time you leave the textfield. An initially empty textfield does not fire the onchange event.
Sample code (IE 8 on Windows 7 computer):
script:
HTML:
I was working on a site that uses Google Checkout buy now buttons, and
I wanted the product picture to change based on what was picked. I was
able to have it change the picture, but if you pick a new item after
that, it keeps the same picture. Here;s the code:

update the data of array when i would have change data in a text box.?
I have a dropdown that when the user selects an item, a function is called. Right it is giving me an error of 'object expected'. Can someone please take a look at my code below and let me know where I am going wrong? When I change the filldesc to an alert, it works fine and returns the correct values.
function filldesc(inputlevel1)
{
alert(inputlevel1);
}
<!-- Level one Headings -->
<select name='level1'

I'm trying to write a form and I need to allow the user to select more than one option from a list of options, if the last option is selected I have a hidden DIV that displays.This all works fine unless the user selects more than one option AND the final option "other" (ie using the control key to make the selection)... the code is below:
HTML Code:
<table>
<tr>
<td width="160">Select your color:</td>
[code]....
I'm having some difficulty in accessing an 'external' function from my onchange event. It will work when the function is included 'inline,' but it's not working when the function is 'stand alone.'Additionally, when it works, the variable isn't being passed - the alert I use says "[object Event]"
Code:
<head>
function nameTextBox2(selectBoxName)
[code]....
I am using a javafunction (onclick in select) in which i am calling a
function in php (thats why i send this to both php and javascript
newsgroups).
in the onclick i call the function "Place_Selected" with the value from the
select (naam_keuze.value)
in the function the value becomes the $zoek_id and searches in the database
for the record with the id of $zoek_id
the naam_keuze.value does not give the value to $zoek_id When i replace naam_keuze.value for a number (15) i works great.
WHAT AM I DOING WRONG? Code:
i need to display selected item from dropdown menu into text box. what i want to do is when user select the item it will display on textbox call programme (java script) and also when button search is click it will display the total number of particular programme (php). for now, selected programme is function but the other one is not.

I'm trying to build a t-shirt creator application w/ php and ajax.You can see where I'm at here.Thus far, I've successfully passed the first parameter from the form via a function called from an onchange event, which uses a php script to pass simple text (for the time being, 'til i get this figured out), which you can see working on the page.trying to update the output w/ each change they make via the form. For every step, the output on the right needs to update.Should I be calling the same function for each onchange, or different functions? Here's what I'm using as far as AJAX/form goes:

I have the following form working with on onsumbit function, but I would like to change it so that instead of having to click the purchase button to see total price, you only have to change the quantity text box input. I just can not seem to get it to work.

var succesful = false;

numQuantity = parseInt(frm.Quantity.value);

numTotalPrice = numQuantity * 4;
frm.TotalPrice.value = numTotalPrice; //new String(numTotalPrice);
successful = true;
} else {
alert("Sorry must order more than 0");
successful = false;
} return succesful;
}

In our class we were assigned a project to create a Web page with 5 text boxes, each with a value attribute of zero. When the user changes the values, it is supposed to call a caclAvg() function. How do I pass 5 values to the calcAvg() function? It specifically states in our book to create an onChange event handler for each textbox. Wouldn't it be easier to somehow create a variable onChange, then after all 5 textboxes have changed, pass the 5 variables along to the function? I know the following code is a mess, I've tried so many ways now. I'm sure this is an easy, routine procedure for most of you.
function calcAvg(value1) {
var functionValue = value1;
}
<form action="" method="post" name"values">
<input type="text" name="value1" value="0" onchange="calcAvg(this.value)" />
<input type="text" name="value2" value="0" onchange="calcAvg(this.value);" />

I have the following code as js for <a href="http://www.oxbowcreations.com/wedding/personalize.php">this</a> site.
Code:
// JavaScript Document
function setQty(id)
{
[code]....
$('#newPrice').change(function() {
this.value = this.value.replace(/[^0-9.]/g,'');
checkPrice();
[Code].....
Ok, so the above code will do the regex when the contents of the textbox changes, but it does not seem to call the checkPrice function I've placed after it does the regex.
I have the above on Change code in a .keyup event and it works as expected.
