JQuery :: Changing The Value Of An Input Field With Val() Is Not Changing The Posted Value?

Feb 2, 2011

I am trying to dynamically clear the value of a form input field and then submit the form.When I used $('#my_field').val('') to clear the field, it was cleared on the screen but when the form was submitted the original value of the input field was posted.My browser is FireFox and I can see using FireBug that when the field is cleared, firebug is still showing the html code with the old value. E.G. <input type="text" value="old_value" />The same situation occurred if I used $('#my_field').attr('value', '') to clear the field.The same situation occurred if I actually changed the value of the field rather than just clearing it.To work around this problem I ended up using the $('#my_field').removeAttr('value') to clear the field before it was submitted.

Changing A Bit Of Text Via Field Input?

Aug 18, 2009

I'm building a template editor and changing some of the variables.

Part 1.

Only at DEALERNAME. Must present coupon at time of write-up. Cannot be combined with any other offer. 1 coupon per customer per transaction. Expires: 00/00/00.s

I need to be able to fill out two fields to change DEALERNAME and 00/00/00.
I found a way to do this but it required the output to be in a field. I need it the output to look no different than before.


Part 2.

I'm using this to change some text via radio button but I would like an option to select how many details are there is the first place. Say they only want 1 or 2 details and not 3.

Head
<script language="javascript" type="text/javascript">
function detail1a(){
document.getElementById("detail1").innerHTML = "Up to 5 Quarts";
}

[Code].....

Changing Opacity Of A Div If The Text Input Field In It Is Active?

Nov 4, 2010

Yeah that was a loooong title. Hopefully it's clear enough :D Right now, my div changes opacity if it's moused over qua the following code:

style="opacity:0.3;filter:alpha(opacity=30)" onmouseover="this.style.opacity=1;this.filters.alpha.opacity=100" onmouseout="this.style.opacity=0.3;this.filters.alpha.opacity=30

but this isn't quite optimal, cause if the user mouses out, it changes back to fade, and the user can't quite see what he's entering. So I would like the div to have opacity=1 when one of the textfields in it is active and opacity=0 when it's not. Is there a way to do that?

JQuery :: Changing Value Of Hidden Field Inconsistent?

May 29, 2010

I am working on bringing my existing website to the iphone/ipod using jqtouch and jquery.

I am stuck using the following code to change the value of a form's hidden field with the value of a clicked link. It works for the first two clicks then no matter what other link is clicked the form's hidden field value is changed to the value of the first or second clicked link?

Is there a more robust, reliable way of achieving my aim?

...$(document).ready(function(){ $('a[name]').click(function() { var str_id = $(this).attr("value"); $("#bookingperiod").val(str_id); }); });...<div class="info">Thu Jun 3rd 2010</div>

JQuery :: Changing Form Field Attributes

Feb 3, 2009

I've got a set of input fields of type text, that I want to change to hidden. The fields are identified by the class name .navtitle. Here is the code I've written to try and change the fields:

Code JavaScript:
$(".navtitle").each(function() {
this.type = "hidden";
});

This works fine in Firefox, but doesn't work in IE, and worse still, breaks all of the other JQuery code I've got as well.

JQuery :: Autocomplete -changing Value Of Hidden Input

Jan 30, 2009

I'm using Jrn's autocomplete jQuery plugin and I'm having trouble changing the value of my hidden input.

The first part works fine - it searches the array and I can select any of the results. However, I'm trying to grab the "id" key value from the array and use it as the value of my hidden input.

Here's my test page.

(I'm using a "GET" form, so submit the form and you'll see that the "account" value submits as empty)

Here's my array:

Code:

And the part that (I believe) should be putting the value of #account into my hidden input:

Code:

Basically, select "Account Five" from the auto-complete, and it should change the value of my hidden input to "0005".

Seems like it should be a relatively simple solution, but I'm still fairly new to JS and jQuery.

JQuery :: Changing Text Field And Invoking The Onchange Event?

Mar 16, 2010

I have a text field on my page, whose value I am setting through the jQuery cal

$('#Expandable').val("fefefe");

However, when I normally type into the text field, certain events occur as the text field value changes. These events do not occur when I set the value like above. So my question is, after I set the value, how do I invoke any onChange handlers?

Changing Text With Changing Random Images?

May 7, 2009

I am a complete novice when it come to Javascript. I copied the script for displaying random images at a specific interval (from javascriptkit.com). I would appreciate knowing whether the following is possible:

The pages are based on tables, so the parts that change are all cells.

1. Can I define text instead of an image in the array? i.e. can I have the image change to say an apple in one cell and the next cell have text explaining what an apple is?

2. Would it be possible to put a countdown timer for when the image/text is going to change?

Image Changing And Changing InnerHTML With JS : Query

Jul 6, 2011

Ive got a small image of a power button and when pressed the inner section on the button changes to yellow, but when its pressed down Im also trying to get part of my H1 (main header logo title) to change to yellow.

Ive created a span with an id surrounding the letters of the H1 that I want to change, the id being : "power";

The javascript that I have come up with so far and works is as follows:

<img id="poweron" src="http://www.sitepoint.com/forums/images/power.png" alt="Power on button" onmousedown="this.src='images/poweron.png';" onmouseup="this.src='images/power.png';"/>

I understand Im not really supposed to be using inline JS, and I know Ive got to create a function for the onmousedown event to trigger changing the H1 text, so am I under the right impression that the JS so far written is redundant and will have to be re-written so thats contained within a script placed just before the closing </body> and an external script for invoking the main function ?

Changing Input Type In IE?

Oct 18, 2005

This code:

if (stealth)
{
document.searchme.query.type = 'password'
}
else
{
document.searchme.query.type = 'text'
}

works in FF but not in IE 6. It fails with "Error: Could not get the
type property. This command is not supported."

A previous post mentioned that in IE type is 'read only'.

Are there any work around for changing input type dynamically in IE?

Changing <options> Within <select> On Input

Jul 23, 2005

I'm making a <select></select> with lots of <option></option>. It
contains all possible options. Because of the length of the list, I
also have an <input type="text">.

This is what I wish to do:

onKeyDown I want all options that don't contain (or begin with, it
doesn't matter which one) the typed letters to be removed from the
<select>.

My problem is that I don't know of any code to find words and identify
letters.

Changing A Background Image Using An Input Box?

Apr 23, 2009

I am using PHP and Javascript to create a user generated page editor. I have everything working except one thing. The user can select the background color of the page using preselected colors. They can also enter in a hexadecimal code to change the color of the background if the color they want isn't one of the preselected ones. These two things work good, but when it comes to them entering in a web address to make an image the background instead of a color, I can't get the background image to change. I have tested it out and when I enter in a predetermined url in the javas source code to test if the pic will display it does, but it doesn't go away after being displayed. So my question is using the code below, how can I get the change the background image using an input box and how can I make it go away when a color is selected instead of an image. Explained below:

Changing Values Input In A Text Box?

I'm a beginner with this stuff, so I'm not sure what sort of code I should use.

Basically I want users to put in words and every time "x" letter goes in, I want it to turn into "y" when they hit a button.

I think arrays would be a good way to go, but I'm not quite sure how I'm going to make it translate S:

Changing Value Of Hidden Input Onclick

Jun 6, 2011

I would like to change the value of a single hidden input onclick. The possible values are text, email and URL.I've tried all kinds of "ways" (inline and in function in a variety of ways,) but nothing. I stripped it down one last time to give it another go, but realize I'm out of ideas, so the code below is simply where I've thrown in the towel.Can someone make this work with a JS function, so that each link may be clicked and change the hidden input's value to the respective value?

Changing Input Image State

Sep 4, 2006

I have some inputs with images that I'm changing the source for onmouseover and onfocus. I want to move the js from the HTML and use a script that does the same thing for all instances of the buttons throughout the site (there's only two at the moment). So far I've got this:

function buttons() {     var goBtn = document.getElementById("go-btn");     var subBtn = document.getElementById("submit-btn");     goBtn.onmouseover=function() { action(this,"go","on"); }     goBtn.onfocus=function() { action(this,"go","on"); }     goBtn.onmouseout=function() { action(this,"go","off"); }     goBtn.onblur=function() { action(this,"go","off"); }     subBtn.onmouseover=function() { action(this,"submit","on"); }     subBtn.onfocus=function() { action(this,"submit","on"); }     subBtn.onmouseout=function() { action(this,"submit","off"); }     subBtn.onblur=function() { action(this,"submit","off"); }          function action(ID,name,state) { ID.src='/images/'+name+'-button-'+state+'.gif' } } window.onload=buttons;

That doesn't look very lean and it works erratically. On a page where both buttons exist, it works in Firefox but only one of the buttons works in IE (the second one) and in Firefox the script won't work if the first button is not present on the page. So what would be the best way to do it?

Changing Attributes Of Input Tag In Cloned Row?

Jun 24, 2010

I'm extending the number of rows of a table by cloning the last row (=newLastRow). Each row has a single input tag in it, with a name which includes the row number and an onclick function call which passes the row number to the function:<input type='text' class='clickable' name='inp8.1' size='20' value='xyx' onclick='toggle("table8");'>The new cloned row has an input tag with the same parameter value as the cloned one, obviously. I need to increment this: name='inp9.1', 'toggle("table9")'.y question is simple but I'm just starting with DOM: how do I refer to the input tag in the newLastRow so I can change these values?
