I have an idea for a little script.....I'm just stuck on one little part: When a user changes the value in a input or textarea box, I want it to change the value of a certain hidden input tag too.
Here's what I have so far:
function getNewValue(inputhidden, textinput) {
var data = document.getElementById(inputhidden);
var text = document.getElementById(textinput);
data.value = text.value;
[Code]....
I've got a select box that, when you choose any option besides #5, it changes the value of a related input box from 0 to 1. This works great except when I hide() the div that wraps this input box. My overall goal is to have the input (and surrounding div) hidden via hide(), and then update this input box when a select is changed.
Here is my code:
$(document).ready(function(){
$("div#edit-qty-56-wrapper").hide();
function enterQty() {
var attrValue = $( "select#edit-attributes-56-1" ).val();
if (attrValue !== '5') {
$("input#edit-qty-56").val('1');
} else {
$("input#edit-qty-56").val('0');
}}
$("select#edit-attributes-56-1" ).change(enterQty);
enterQty();
});
I have the php code working to produce the drop menu and use the
Code:
onChange="flagmastcountryflag(this.value)"
to pass the value to javascript for process.
Code:
<?php
// Creates a pull-down list of flagmastcountries
function get_flagmastcountry_list($name, $selected = '', $parameters) {

I'm using Javascript to create some dynamic content on my website. Basically it's looping through some values and updating an input field with the values.
What I'm wondering is, do I have to do this using a form and an input field? Is there a way I can get Javascript to update the content inside a DIV for example?
Can I target the element and base an onChange outside of directly calling it in the element tag?
Due to the nature of my script, the best I can do is wrap a tag around the element.
example of what I am trying to do
Code:
<script>
document.form.field1.onchange = function();
<script>
And if this might work, can I call it in the head or must it come after the element.
I have a PHP page that generates a list box with several options in it.
I would like to have a "view" link next to the list box. When the user
changes the contents of the list box, I would like the view link to
update to point to the image representing that selection. So for
example, if the list box held names of images I would want the view link
to always point at the correct image.
To further complicate this matter, the selections of the listbox are in
PHP variables.
I basically have little to no experience with javascript and could use
some guidance in figuring this out.
Specifically, assume I have a div tag of absolute dimensions. I need
to figure out, first, whether or not the text inside the div tag is
partially hidden by the overflow setting, and if so, what the hidden
text is.
Is this even possible? Obviously, the rendering engine in the browser
"knows" this information, but is it accessible through Javascript?
I am trying to update the textarea with the checkboxvalues.
When checkboxa is checked, checkbox1, checkbox2, checkbox3 are checked and their values should be shown in textarea like 1,2,3
If checkbox1 is unchecked the textarea should show 2,3 same thing applies to checkbox2 and checkbox3
Below is the code where i attempted to do it.
I have a php function that displays a dropdown menu of values pulled from a mysql database. I want the selected menu item to be inserted into the 2 text areas automatically. Now, if I use a <a href tag it works fine but if I have it in a dropdown, it doesnt Code:
View 7 Replies View RelatedI'm trying to update a textarea's value with Javascript. The code is similar to:
console.warn("Before set, value is " + document.getElementById('myTextArea').value);
document.getElementById('myTextArea').value = 'OMGWTFBBQ';
console.warn("After set, value is " + document.getElementById('myTextArea').value);
Although the Firefox and Chrome consoles show that the value property is updated, this is not reflected in the page itself.The specific function is invoked from an onfocus handler of another element. The textarea itself is lazily initialised from the same method, by using:
var messageText = document.createElement('textarea');
messageText.id = 'myTextArea';
someParent.appendChild(messageText);
Obviously if I use the console rather than let the script run it does work.
I have a page with 2 forms on, namely form1 and form2!!
In form1 there is a listbox with a drop down of IDs. Now if the user selects a different ID in that list, form2 hidden variable (qualstatus) needs to be updated with the new ID which was selected in form1. I have tried the following.
function changequal() {
document.form2.qualstatus.value = document.form1.qualstatus.value
}
with a
<select name="qualstatus" id="qualstatus" onChange="changequal()">
however this does not seem to update the value of
<input name="qualstatus" type="hidden" id="qualstatus" value="<%=(rsAction.Fields.Item("qualStatusID").Value)%>">
i have a select box, when user select value other than 'H' then the hidden <DIV> element will showed up, and when user select value 'H' the <DIV> element will hide again

<option value="H">Is Hidden</option>
<option value="S">Show me the DIV</option>

I am very new to jquery and I am trying to set the value of a textarea which is not in a form, into a hidden field which is in a form. In the text area, I have given it an id called refnote and ive used the text() to get the text in it. However, the problem is setting the retrieved text in a hidden form field.
$('form').submit(function(){
alert ($('#refnotes').text());
return false;
});

I have a site that writes a checkout table/cart from one window to another. Just to be current I've decided to allow the customer to change the quantity of the item ordered by putting an input type text in each rows 'quantity' column. The idea is that they can change the number of that rows particular item they wish to order. The onchange of the input element should multiply the new 'quantity' value by the 'cost' innerHTML of the cost column and then set the 'subtotal' innerHTML in the footer row to match. An 'onmouseover' changes the 'rowsubtotal' to match the footer 'subtotal' innerHTML. Unfortunatley the 'qtymultipl()' function called by input onchange only results with 'onmouseover' changing the 'rowsubtotal' and footer 'subtotal' to 0.00.

I have two input fields and I want the second updated every time I change a value in the first. I wrote this function but it doesn't work until the first element lost focus (for example I clic anywhere or press

I'm trying to append an onChange attribute to an element created through javascript. The following doesn't work. The select is created and has the proper name and id but no onChange..

sel.id = 'size[' + i + ']';
sel.onchange = "changeMini();";
I have a small HTML form that has a textfeild which when clicked on open a calender, this works fine. I also want to display the selected date in another textfeild using "OnChange". This is what I am working with:
TEXTFEILD
Code:
<input name="startDate" type="text" class="bodytext" id="startDate" size="10" maxlength="10" onclick='scwShow(this,this);' onchange="PrintValues3();" target="_parent._top" onmouseclick="this.focus()">
[code]....
The result2 is then displayed in a textfeild called "result2" but in my case its not.
Is it possible to use both "OnClick" and "Onchange" together?
