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 $('#my_field').removeAttr('value') to clear the field before it was submitted.
I'm building a template editor and changing some of the variables.
Part 1.
Only at DEALERNAME. Must present coupon at time of write-up. Cannot be combined with any other offer. 1 coupon per customer per transaction. Expires: 00/00/00.s
I need to be able to fill out two fields to change DEALERNAME and 00/00/00. I found a way to do this but it required the output to be in a field. I need it the output to look no different than before.
Part 2.
I'm using this to change some text via radio button but I would like an option to select how many details are there is the first place. Say they only want 1 or 2 details and not 3.
Head <script language="javascript" type="text/javascript"> function detail1a(){ document.getElementById("detail1").innerHTML = "Up to 5 Quarts"; }
but this isn't quite optimal, cause if the user mouses out, it changes back to fade, and the user can't quite see what he's entering. So I would like the div to have opacity=1 when one of the textfields in it is active and opacity=0 when it's not. Is there a way to do that?
How do I change the value of "id" of a text input field?I am using the function attr (), but it seems every time I call the function adds an id.$ ("input.buscaf.") attr ('id', obj);"obj" is the value of the id which will be exchanged.I have to change the value of the id because I'm using masks values.
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>
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:
I'm writing a dynamic form that allows users to add fields. Thesefields are contained in a table.I have this function to clone the rows (my table has an ID of
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.
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?
I currently have a normal link like Code:<a href="http://sitepoint.com" class="link">sitepoint</a> and when a user clicks on it I want to be able to change the "link" class to a different class. However, I don't want to add anything to the actual link html. Is it possible to do this using javascript without modifying the original link code?
I'm working on implementing watermark in datepicker text field (JQuery V1.8.9). I have a datepicker field with watermark set (dd/mm/yyyy). Watermark text displaying in gray color. When I select a date, the text field still having the gray color instead of changing to black color. but, when i key in the date and focus out, it's working fine. Also, this is working fine in Chrome but not with Firefox. I'm not sure the exact cause...
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?
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 ?
I have a table with a list of items which currently show 8 items per page. I want to have an input box at the top of the page so if I want a different amount of items to be shown i enter the number and the page alters the pagination to what ever number is entered.
However, the problem is that it also changes the value of the input form Submit button. How can I change the code so that it only changes the input box of a certain ID?
I have a button that needs to increase/decrease the value of a text field when clicked. This code is working in Internet Explorer and Chrome, but not Firefox.
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.
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:
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?
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:
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?
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?
