Change element text value using jquery not work

I have one form generated from rails. I tried to change to the input order_bill using Jquery in the firefox firebug console, but it does not work. I am new to jQuery.
<form class="edit_order" id="edit_order_1" action="/orders/1" accept-charset="UTF-8" method="post">
<input name="utf8" type="hidden" value="✓" /><input type="hidden" name="_method" value="patch" />
<input type="hidden" name="authenticity_token" value="1IBaRCZ4S1hYp1" />
..
<div id="bill", class="field">
<label for="order_应付款项">应付款项</label><br>
<input type="text" value="4200" name="order[bill]" id="order_bill" />
</div>
<div class="actions"> .. </div>
<div class="actions">
</div>
</form>
In the firebug JS console,
$('#order_bill').html("asdasdddddddddddddddd");
$('#order_bill').html("asdasdddddddddddddddd");
$('#order_bill').html("asdasdddddxx");
$('#bill').html("asdasdddddxx");
But none change on the Html page. Am I wrong?

Try this:
$('#order_bill').val("asdasdddddddddddddddd");
instead of html();
because the value you want to change is present in value attribute of tag.

You may need to make sure you import a jquery library in your html page
http://code.jquery.com/jquery-2.2.4.min.js
if you want to get value just Type
$('#order_bill').value
and set the value
$('#order_bill').value = "enter Value"
But if You Want to add a text in div using jquery
$('#order_bill').html("Value");

Automatically show form value on page load or submit using .innerHTML

I'm trying to find the simplest, non-expert-coder solution to displaying a search query.
I have a search form where onclick of the submit button it displays the form value underneath. This is the code:
<input type="text" name="searchfield" id="searchfield" value="" />
<input type="submit" name="submit" id="submitSearch" value="Submit" onclick="document.getElementById('output').innerHTML = document.getElementById('searchfield').value" />
<div id="output"></div>
The page reloads on submit rather than going to another page.
Is there a simple way to manipulate my code do display the value in the output div automatically upon page load, rather than onclick?
So whatever was placed in the search box will automatically be displayed once the page loads after refresh or submit. If nothing was entered, then nothing will show.

There are many ways to achieve this, but this would do the job:
<input type="text" name="searchfield" id="searchfield" value="" />
<button onclick="document.getElementById('output').innerHTML = document.getElementById('searchfield').value">Submit</button>
<div id="output"></div>
And using PHP,
<input type="text" name="searchfield" id="searchfield" value="" />
<input type="submit" name="submit" id="submitSearch" value="Submit" />
<div id="output">
<?php
if($_GET['searchfield'])
echo $_GET['searchfield'];
?>
</div>

Redirecting after form submission in Javascript

I hope someone can assist with this. I dont have access to the website backend, so I cant change the js script uploaded there. What I am trying to achieve is make a simple form to submit an issue report and then display a "Thank you" popup and redirect back to main page of the account on our page.
So I can make a form no problem. I copied one of the functioning forms by going to Edit link and clicking on Show Source in Page Body. But I can't stop the default behavior of it going to another page after Submit button is pressed. I suspect it is in js script on the back end. I'll copy code below.
<center>
<b>App Issues Report Form</b>
<br>
</center>
<form action="/Modules/SendForm" method="post" class="form" id="NewForm">
<input name="formFields" value="CONTACTID,AgentName,Notes" type="hidden">
<input name="formLabels" value="Contact ID:,Agent Name:,Notes:" type="hidden">
<input name="fromAddress" value="no-reply#callcenter.com" type="hidden">
<input name="toAddress" value="name#CallCenter.com" type="hidden">

class="validate[required] xlarge" value="##LOGGEDIN_AGENT_FIRST_NAME##
##LOGGEDIN_AGENT_LAST_NAME##" type="text">
</div>
</div>
<div class="clearfix">
<label>Notes:</label>
<div class="input"><textarea id="Notes" name="Notes"
class="validate[required] xxlarge"></textarea>
</div>
</div>
<div class="clearfix grey-highlight">
<div class="input no-label">
<input class="button blue" value="Submit" type="submit">
<input class="button grey" value="Reset" type="reset">
</div>
</div>
</form>
<script type="text/javascript">
$(document).ready(function() {
$("NewForm").click(function( event ) {
alert( "Thank you for your feedback" );
event.preventDefault();
});
});
</script>
It used to have only this at the end when I copied the code:
<script type="text/javascript">
$(document).ready(function () {
new setupAjaxForm('NewForm'); });
</script>
I tried searching and suggestions here didnt seem to work:
How to redirect user to another page after Ajax form submission
How to redirect user to another page after Ajax form submission?

The first thing you have to look at is action="/Modules/SendForm" - this is what does the redirection. If you don't want to redirect, set this to the name of the page you have the form. Obviously there is a whole lot more to forms and redirection (and some other js code might influence this too, nonetheless we don't see what the function setupAjaxForm is supposed to do here), but this is really the first thing to check / get right.
EDIT: I think I understand it more now: basically if you don't have access to the /Modules/SendForm page (where most probably, among others, like form validation, the redirection also happens, then you can't do much to change the redirection.

html form trying to http get when a button is pressed

Ive got a html form with a few select lists and a text box in it. I also have a submit button which is outside of the form. The reason for this is I want to construct the parameters myself, as I dont want the content of all of the select lists. The problem I am having is, that when I press my submit button,The form automaticly trys to redirect to the same page, but with a ? at the end with all the contents of the form. I am also having problems where window.location.href is not working inside the submit() javascript method, but I am not sure if this is caused by the form issue or not. Example code:
<form>
<input name="cName" type="text" class="input-xlarge" id="input01" placeholder=
"Enter title" />
<div class="control-group">
<hr />
<label class="control-label" for="select01">Select box 1</label>
<div class="controls">
<select id="select01" name="type" onChange="reportModification(this.value)">
<option>One</option>
</select>
</div>
</div>
</form>
<button class="btn btn-primary" onClick="next()">Next</button>
This is not the exact code from the page, just a replica.So it might not be valid html in some places. Thanks for the help :)

The reason you get parameters in the url is that a get request is used instead of a post request. you should use:
<form method="POST" action="">
Also why is your button outside the form? you could have this instead:
</div>
<input class="btn btn-primary" type="submit" value="Next" onClick="next()" />
</form>

I think your button has to be inside the form element. You could use an onsubmit in the form element to intercept the form before it gets sent to the server. Here you could manipulate the values before they go. You would also need an action attribute in the form. If your function returns true, the data will be submitted, false and it won't.

jQuery modal window removes elements from my form

jQuery, when i use it to create a modal window which contains form elemets,
it takes out those elements when i submit the form.
example of the form:
<form enctype="multipart/form-data" action="/system/article/add/" class="from" method="post">
<label for="article_title" class="required">Title:</label>
<input class="formfield" id="article_title" name="article_title" value="" type="text">
<label for="url" class="required">Url:</label>
<input class="formfield" id="url" name="url" value="" type="text">
<div id="add_photo" style="width: auto;" class="ui-dialog-content ui-widget-content" title="Add Photo">
<label for="photo_title" class="optional">Photo title:</label>
<input class="formfield" id="photo_title" name="photo_title" value="" type="text">
<label for="photot" class="optional">Photo thumb:</label>
<input type="file" name="photot" id="photot" class="formfield">
<label for="photo_checkbox" class="optional">Include lighbox?</label>
<input name="photo_checkbox" value="0" type="hidden">
<input class="checkbox" id="photo_checkbox" name="photo_checkbox" value="1" type="checkbox">
<label for="photo_big" class="optional">Photo:</label>
<input type="file" name="photo_big" id="photo_big" class="formfield">
</div>
</form>
exaple of JS:
<script>
$(document).ready(function(){
$("#add_photo").dialog({
autoOpen: false,
buttons: {
"Ok": function() {
$(this).dialog("close");
}
}
});
});
So what i nocited during the inspetion via firebug, is that jquery actually removes my form elements within #add_photo and puts them outside the form in DOM, so even tough in html the modal dialog is within my form, in DOM it isn't ....
An this is the reason why i'm having the issue!
Have anyone encountered simmilar problem?
Any solution?! Thank you very much!

I just had the same problem. I solved it by adding another
<div id="beforesubmit" style="display:none"></div>
at the end (but inside) of the form and then you have to add this to jQuery:
$("form").submit(function() {
$("#add_photo").prependTo("#beforesubmit");
});
This will make sure that before the form is submit your dialog div will be put back in between the form tags. Thanks to arnorhs I came to this solution.
Cheers!

I'm not sure what dialog box plugin you're using, but I would suspect that the dialog box plugin is pulling the DIV out of the form and placing it into the body of the page, so It can bring the box in front of the page, outside of the form element.
So to rephrase, in order for the dialog box plugin to make your dialog appear in front of all the content on your page, it needs to remove it from whatever element it is sitting in, no matter if it's a form or anything else.

The form needs to be inside the div. That's how it is in all the Dialog examples. Not sure how you're going to do that with the title and url inputs not being on the dialog. Couldn't you put them on it too?
This wouldn't have the problem:
<div id="add_photo" style="width: auto;" class="ui-dialog-content ui-widget-content" title="Add Photo">
<form enctype="multipart/form-data" action="/system/article/add/" class="from" method="post">
<label for="article_title" class="required">Title:</label>
<input class="formfield" id="article_title" name="article_title" value="" type="text">
<label for="url" class="required">Url:</label>
<input class="formfield" id="url" name="url" value="" type="text">
<label for="photo_title" class="optional">Photo title:</label>
<input class="formfield" id="photo_title" name="photo_title" value="" type="text">
<label for="photot" class="optional">Photo thumb:</label>
<input type="file" name="photot" id="photot" class="formfield">
<label for="photo_checkbox" class="optional">Include lighbox?</label>
<input name="photo_checkbox" value="0" type="hidden">
<input class="checkbox" id="photo_checkbox" name="photo_checkbox" value="1" type="checkbox">
<label for="photo_big" class="optional">Photo:</label>
<input type="file" name="photo_big" id="photo_big" class="formfield">
</form>
</div>

This article describes how to solve your problem:
You’ll see that the content we had mid-way through our page has been marked up with additional classes and, most importantly, placed at the bottom of the page immediately before the closing tag. Why is this important? Because it also means that any ASP.Net controls you place within this dialog will also appear at the bottom of the page, outside of the page’s tag. This means you won’t be able to get a handle to them on postback.
What’s the solution? Well, there are two options:
Move the elements back to the form, and manually submit when the button is clicked
Clone the elements when you create the dialog, then clone the values back, trigger click on the original button (or, if you only have one or two values to post back, simply assign the values to an ASP.Net hidden field control).

From http://blog.coreycoogan.com/2010/12/01/jquerys-dialog-and-form-problems/
Tie it to the form by doing $("mydialog").parent().appendTo($("form:first")).
Note that you have to this call after you already called $("mydialog").dialog()

As seen in the answer for this question, jQuery dialog has a field appendTo, that can be used to configure where to put your dialog (div-wise) on initialization.
This seems to be the least ninja-workaround version to tackle the problem.
