I have a total of two input values. Only one value passes to the url of the next page, but both should. What's causing this?
JSFiddle: http://jsfiddle.net/p8dCC/
HTML:
<!--form action="device" onSubmit=" get_search(); return false;" id="search-form-4" method="get" target="_top"-->
<div class="fix">Brand</div>
<input class="inputs" type="text" id="search_id" name="q3" placeholder="Send this" required="required" />
<br/><br/>
<div class="fix">Model</div>
<input class="inputs" type="text" id="search_id" name="q4" placeholder="And send this one too" required="required" />
<br/><br/>
<input id="search-button" class="" type="submit" value="continue" data-target="http://www.google.com/?item-description" />
<!--/form-->
You have two elements with the same id in html. So when you do this $('#search_id').val() only one of them will get evaluated and not both. Ids are supposed to be unique
After testing your code in a test page, I found that both inputs were in fact being passed through the URL.
You have commented out the form tags which I'm not sure if you did just for purposes on here.
kjs is correct as well, though using the same id would only effect the HTML. Using get as the method would bypass this issue as it would be passed the unique "name" attribute.
A form tag is required if you expect the html submission mechanism to work correctly on its own.
In the Javascript you posted though, you are treating document.location as an html element, wrapping it with jquery, then trying to use jquery's attr method on it. This won't work. Just access "location.href" directly without using jquery.
Additionally, as pointed out by another answer, your ids should all be unique.

I have many forms on my page that are DYNAMICALLY added and I have a button that I want to trigger a reset to all the forms on the page except one.
An example of a dynamically added form is:
<form>
<label for="code">Question code:</label>
<input type="text" id="code" name="code" maxlength="25" class="used"/>
<div class="clear"></div>
<label for="title">Question:</label>
<input type="text" name="titl" name="title" maxlength="255" class="used"/>
<div class="clear"></div>
<label for="hint">Hint:</label>
<input type="text"id="hint" name="hint" class="used"/>
<div class="clear"></div>
<input type="hidden" name="type" value="tapper" class="used">
<input type="hidden" name="optionsType" value="none" class="used">
<input type="reset" value="Cancel" class="delete-button">
<input type="button" value="Add" class="action-button" onclick="pushQuestion(this);">
</form>
Also, after each form is dynamically added, I call:
$('form').on('submit', function (e) {e.preventDefault()});
Now, when I want to reset the forms, I call the following:
$('form').trigger('reset');
When entering this into the console, I get an array back with all the DOM forms. Some forms get reset, but others are unaffected. There are no errors being reported. Does anyone have any thoughts as to why some get reset while others do not?
EDIT Thanks for the help, but the issue has been resolved. See the problem in the comments below
After a few hours of tinkering, it was discovered that the issue was the result of the way the forms were cloned.
I was doing a deep clone of the existing forms which was yielding an odd state of the form which means that when .trigger('reset') was "triggered", it would reset the form to the default state of the clone which may or may not have included some original data yielding a reset that did not appear to be doing anything.
A workaround was to first fire a loop over all the inputs with .attr(value,'') to clear the attribute value after cloning. Then the .trigger('reset') functioned as expected.
I've noticed some inconsistencies with form handling among the various browsers. One gotcha is that the less standards-compliant browsers require an input or button with type=submit for some things to function correctly. I know this is that case at least with submitting a form by pressing the enter key in any text field.
Maybe try adding an <input type='submit'/>?
At some point during the development of my app, AngularJS forms stopped working... Yes that means they used to work. That is, form elements are supposed to create their own scope with every <input /> by their name. However all my forms are now completely empty, as if I had no input elements with the name attribute. Now I can't make any sort of form validation. I've tried even the most trivial forms and still nothing:
<form name="form>
<input type="text" name="input" required />
</form>
Any suggestions as to how to debug this?
Hi to do validation your input have to have model directive please see here: http://jsbin.com/deref/1/edit
<form name="form">
<input type="text" name="foo" required ng-model="input.model"/>
<span ng-show="form.foo.$error.required">required</span>
</form>
Try console.log on the scope
console.log($scope.form);
If you have your controllers set up correctly, your form should be attached to the scope of controller.
I'm new to html and JS and I have a form with a few fields that I need posted to a URL.
<form>
<div>
<label style="font-size:16px" for="title">Title:</label>
<input type="text" id="title" maxlength="128"/>
</div>
<div>
<label style="font-size:16px" for="description">Description:</label>
<textarea id="description" maxlength="1999"></textarea>
</div>
<div>
<label style="font-size:16px" for="idnumber">IDNumber:</label>
<input type="number" id="idnumber"/>
</div>
</form>
I need the values entered into this form to be posted to a URL that already knows how to process the input. I'm sure this is easy to do but I'm new and I'm having trouble finding a solution. Apologies for any incorrect terminology. Thanks!
You can use the action attribute:
<form action="some/url" method="post">
<!-- ... -->
<input type="submit" value="Submit" /> <!-- Submit button -->
</form>
You have to add an action to your form tag that points to a server side script.
<form action="myscript.php" method="post">
Alternatively, you can use JavaScript to post it as an AJAX request which submits the request without a page refresh.
I'd say you're on the right track. This would be perfectly easy using basic HTML: Add an action="mySubmitPage.php" to the form element. It sounds like you want to do it without refreshing/changing the page, though (at least, that's how it sounds by "with Javascript")
That will involve an "asynchronous" submit. The fancy term is "AJAX". That part can be a lot easier using some form of Javascript framework, especially if you want to support all browser quirks. Here's an example of doing it using JQuery, for instance:
jQuery - Send a form asynchronously
I know that may sound silly, but I'm trying to submit a form on a page inside an iFrame, from the parent site.
Here's an example of the form:
<form action="/add_email" method="post">
<div class="field">
<label for="newEmailAddress" style="width: auto">Add new email address</label>
<input type="text" id="newEmailAddress" name="email" value="null" class="text-field" />
<input type="hidden" name="__app_key" value="null"/>
<input type="submit" value="Add address and send activation email">
</div>
</form>
As you can see, the Submit button, and the form itself both lack a proper name or id, this is not something I have control over. (It's on an external website.)
Any suggestions?
When no name is given to the form then form has the default form name in a form of array
ie form[]
hence one can create as many forms in script, the default name's index will increase.
Hence one can use it accordingly.
Since it is an external website — no. The Same Origin Policy prevents it.
If it was the same website then you could communicate across frames and then access the form via its numerical index in the forms object (but you would also likely be able to give it an id and use that instead).
I came to see that form file input field value cannot be set with javascript for security reasons.
I just want to copy a FILE input to another form and post it, I searched for a work around and could not find anything, is it possible?
UPDATE: my code:
function prepareUpload( filevalue ){
document.getElementById('logo').value =filevalue;
var mform = document.getElementById('sleeker');
ajaxUpload( mform,'<?php echo base_url(); ?>'); // a methods to upload...
}
<input class="input-file-upload" type="file" size="20" name="logodummy" id="logodummy" onchange="prepareUpload( this.value );" />
<form action="" method="post" name="sleeker" id="sleeker" enctype="multipart/form-data" onbeforesubmit="return false;">
<p><input type="hidden" name="logo" id="logo" /></p>
</form>
Anything other thatn file input are working fine, and I could receive with $_POST, but $_FILES doesn't have values. And this code alone working fine too. I think this coe is enough?
Yes, you can place the <input type="file"> outside your HTML form, and then use the onChange event to fill an <input type="hidden"> within the form that gets posted:
<input type="file"
onchange="document.getElementById('hidden_file').value = this.value;" />
<form method="POST">
<input type="hidden" id="hidden_file" value="" />
<input type="submit" />
</form>
However in modern browsers, you will only be able to access the file name, and not the full path. You may want to check the following Stack Overflow posts for further information on this topic:
Can’t get the complete address while uploading a file
How to get the file path from HTML input form in Firefox 3
UPDATE:
The original question made me think that you only needed to copy the "file name" to another HTML form, and not the whole <input type="file"> representation.
Further to the update, I assume you meant something like this:
<input type="file"
onchange="document.getElementById('hidden_file').value = this.value;" />
<form method="POST">
<input type="file" id="hidden_file" value="" />
<input type="submit" />
</form>
Unfortunately the above does not work. Firefox will return "Security error code: 1000" if you try the above example.
As for some workarounds, you may want to the check David Dorward's suggestions:
Using cloneNode
Moving the input field with appendChild before submitting the form
You could move the file input to the other form (with appendChild or insertBefore), submit the form, and then move it back.
I haven't tested this in depth, but it appears to work in Firefox.
Use cloneNode
var copy = file_input.cloneNode(1);
form2.appendChild(copy);
Very much similar to cloneNode except in jQuery
In an xulrunner browser (like firefox) I have successfully used something like the following:
$('input:file').clone().appendTo($('#mainform'));
This should copy all file input objects into the form with id=mainform.
Avoid using the id attribute in the objects to be cloned. id's should always be unique.
I realised that this might be late to the party, but with HTML5, you can use the "form" attribute to target a form, like [form id="the_form"]...[/form]....[input form="the_form type="file" ... /]
