got a problem and cant find the solution.
I am writing a chat. When a new user opens my site (a new session) a div popes out and the user is asked to fill in his name.
The form works fine when I use an input submit. I want it to work without the submit button, I want it to work when i press a div.
here is my code
html:
<form name="form" id="form" action="index.html" method="post">
<span id="nspan">First name:</span> <input type="text" id="firstname" name="name">
<div name="enter" id="enter">Submit</div>
</form>
the jquery:
$(document).ready(function(){
$("#enter").click(function () {
$("#form").submit();
});
});
nevermind is correct - no problem with that code.
Here's the JSFiddle to prove it: http://jsfiddle.net/8Xk7z/
Maybe you problem is that the id "form" is to general a name, and you already used it for another form.
Another thing, why not use a button or a link? You can style it like you want. Be careful when you use thing for what they are not suppose to be used for, it my give unexpected side effects.
In your case, you may only be able to login to you chat using a mouse, that would exclude blind people. You would also not be able to use the tabulater to get to the login "button". And last, if you are blind and uses a screen reader your would actually not know that there is at login "button", as the reader would not recognize the div as something you can click.
I would recomend using the button-tag like this
<button id="enter">Submit</button>
Or the a-tag like this
<a href id="enter">Submit</a>
If you don't like the predefined styling of them you may always override the styling.
try to define jquery at top of the page
<script src="https://code.jquery.com/jquery-3.2.1.js"></script>
Then put your script at next.
still issue.
Please check your other function on same page works fine or not.

I've wrote a simple 'add page' form to a small CMS I've built and I have a simple preview feature which submits a form and opens the front-end version of the page in a new window.
To achieve this up until now I've used:
<input type="submit" name="pagepreview" value="Preview" formtarget="_blank">
Apparently the formtarget which made this possible is depreciated (which I never actually knew) and it seems that Google may have removed this feature in their latest update as it's stopped working (but still works in Firefox).
What's my alternative here? The answers I've found all point back to formtarget or target but neither work any longer.
Ideally I'd want to avoid Javascript but if that isn't possible - how would I submit the form to a new window using Javascript or jQuery?
EDIT:
Apologies for not explaining well enough - I can't add the target attribute to the form as only one button allows a new window (the preview button) the others just submit on the same page. Javascript appears to be my only way to do this.
<form action="..." method="..." target="_blank">
<input type="submit" name="pagepreview" value="Preview">
</form>
If you need to change the target dynamically:
$('input[type="submit"]').click(function(event){
var $this = $(this);
var $form = $this.parents('form');
$form.attr('target',$this.attr('formtarget'));
$form.get(0).submit();
event.preventDefault();
});
like this: (add target = "_blank")
<form action="" method="" target="_blank">
<input type="text" />
</form>
I'm working with an old ASP WebForms page in which there is a link which opens in a new windo using javascript. This link includes a GET-parameter, like this:
<href="javascript:window.open(http://myurl.com?MyId=123).focus()">
Search for object
</a>
What I would like to do is replace this GET-parameter with a Post-variable in order to avoid the value of MyId being stored in the browser-history. Possibly something like:
<input type="hidden" id="MyId" name="MyId" value="123">
<a href="submitSearchCriteria()">
Search for object
</a>
Note: Since this is a webforms page, the whole contents of the page is within a pair of <form>...</form> tags which post back to the page itself, and I don`t want to mess with these. The page I would like to link to is another page.
My question: Is there some fairly simple, clean and safe way to pass along a Post-variable from within a link like this? I would prefer to do this without including any third-party java script libraries if possible (I want to minimize the necessary changes to an aging system).
Any ideas?
Add your MyId in your form:
<input type="hidden" id="MyId" name="MyId" value="123">
Then your hyperlink:
Search for object
Then use javascript to change your form action:
function submit(){
[Your Form].action = "[Your Action]";
[Your Form].submit();
}
The form submits but as the page refreshes, the form action goes back to what it was before. But this could depend to where you point back your new action. You could add something to handle the response. This is the easiest solution if you ask me. But for the cleanest, you should try reading about AJAX.
I have a html form, with a custom file upload field. And by that I mean that I have moved the actual file field beyond the borders of the page with css, that I have a custom input field and button in place, and that I have a jquery click event attached to that custom button to trigger the file input dialog.
It all works fine, in every browser.
But I need to submit the form through javascript. And I got somewhere that IE remembers my actions with javascript as a malicious manipulation of the file input field and blocks my access with an error "access denied" when I invoke document.formName.submit().
Is there a way around this, because I have gone completely mad by trying to search for a solution. I seriously don't want to use the default file input field, as every browsers renders it differently and messes up my design..
code:
<form name="thisForm" onsubmit="return false;" enctype="multipart/form-data" method="post" action="index.cfm/somepage">
<input type="file" class="hidden" name="hidden" id="hidden" />
<input type="text" name="shown" id="shown" />
<button id="button">browse..</button>
<input type="submit" id="submitForm" />
</form>
<script>
$('button').click(function(){
$('#shown').val($('#hidden').val());
});
$('submitForm').click(function(){
validateForm();
});
function validateForm()
{
//regular expression validation against all other input fields in the form
//not the file input field
validateVAT();
}
function validateVAT()
{
//connect to external service to check VAT
submitForm();
}
function submitForm()
{
document.thisForm.submit();
}
</script>
UPDATE:
I just tried to first upload the file, before submitting the form, through ajax, but that also gave me the acces denied error.. >_>
I was having the same problem, and I solved it by using a styled <label> tag with a slight workaround in Firefox.
http://jsfiddle.net/djibouti33/uP7A9/
The Goals:
allow user to upload a file by using standard html file input control
hide standard html file input control and apply own styling
after user selects file to upload, automatically submit the form
The Browsers:
Firefox, Chrome, IE8/9, Safari
IE7 didn't work, but it might if you add it to the workaround detailed below.
The Initial Solution:
Hide the file input by positioning it offscreen. Important not to display:none as some browsers won't like this.
Add another styled element to the page (link, button).
Listen for a click on that element, then programmatically send a click to the file input to trigger the native 'file explorer'
Listen for the file input's onchange event (occurs after a user chooses their file)
Submit the form
The Problem:
IE: if you programmatically send a click to a file input in order to activate it (2), programmatically submitting the form (5) will throw a security error
The Workaround Solution:
Same as above
Take advantage of the accessibility features built in to the label tag (clicking on a label will activate it's associated control) by styling
a label tag instead of a link/button
Listen for the file input's onchange event
Submit the form
For some reason Mozilla browsers won't activate a file input by clicking on it's label.
For Mozilla, listen for the click on the label and send a click event to the file input to activate it.
Hope this helps! Check out the jsfiddle for details on the html/js/css used to make it all work.
I found the answer myself, After 2 days of crazy trial&error. I hope I can help somebody with this..
I removed the hidden file input field from my coldfusion page and replaced it by an iframe tag. That iframe tag linked to another coldfusion page, containing another form with the removed file input field.
Now when I use javascript to click the file input field, which is still hidden from view, it still gives the browse file dialog without a hitch. But when I use javascript to submit the form, through the iframe, miraculously, it submits the form in the iframe, making it possible to upload the file in some serverside scripting of your preference.
iframe code:
<form id="formFileUpload" class="formFileUpload" name="formFileUpload" method="post" action="../actions/act_upload_file.cfm" autocomplete="off" enctype="multipart/form-data">
<input type="file" class="buttonFileHidden" id="inputFile" name="partnersLogo" />
</form>
iframe itself:
<iframe src="admin/dsp_file_upload.cfm" id="ifu" name="ifu" class="buttonFileHidden">
</iframe>
javascript click & submit:
ifu.document.formFileUpload.partnersLogo.click();
ifu.document.formFileUpload.submit();
If you're like me, and you don't want to use an iframe, and you weren't too keen on the label solution mentioned above, you can just position the original button above the styled button with an opacity of 0.
Using the example above, you would still have:
<input type="file" class="hidden" name="hidden" id="hidden" />
<input type="button" name="shown" id="shown" value="Add File" />
But .hidden would be defined like so:
.hidden {
position: absolute;
left: -150px;
opacity: 0;
filter: alpha(opacity=0);
}
Config: Set the opacity to 0.5 (or =50) to see the transparent element and tweak the left positioning.
Arguably just as hacky as the answers above, but a bootstrap-friendly solution, and in my case, the only one that worked.
I found a weird solution to solve this problem.
It thought about the js click thread. If it goes out of this thread, there no more security issues.
I chose to use window.setTimeout. see sample below:
<script type="text/javascript">
$(function () {
$("#<%= this.fuDoc.ClientID %>").bind('change', uploadFile);
$("#<%= this.btnUpload.ClientID %>").click(chooseFile);
});
function chooseFile() {
$("#<%= this.fuDoc.ClientID %>").click();
}
function uploadFile() {
var fu = $("#<%= this.fuDoc.ClientID %>");
if (fu.val() != "") {
window.setTimeout(function () {
<%= this.ClientScript.GetPostBackEventReference(this.btnUpload, "") %>;
}, 100);
}
}
</script>
<asp:FileUpload ID="fuDoc" runat="server" style="display: none;" />
<asp:Button runat="server" ID="btnUpload" Text="upload" OnClick="btnUpload_Click" />
<asp:Label ID="lbltext" Text="" runat="server" />`
then, no more acces denied!
This is an old post but the problem still arises. This may not be working because jQuery kindly fails silently. I was having this problem and wondering why my hidden form would not submit and the file get uploaded. I started off by using jQuery, but then I went vanilla. It still didn't work but looked as though an exception was being thrown in my .click() function.
Running
try {
document.getElementById('formid').submit();
} catch (e) {
alert(e);
}
showed that we indeed were throwing an error, and quick research showed that this was because IE DOES NOT SUPPORT SIMULATED CLICKS ON A FILE INPUT. This means that when the form went to be posted, IE would refuse to post the form
Excuse the bold caps, but I know many people will see text and not read it
Have you tried
$('button').click(function(){
$('form[name=thisForm]').submit()
});
You need to change onsumbit='return false;' to onsubmit='return validateForm()'.
Then have validateForm() return true if the form passes your validation checks, or false if it does not.
The onsubmit='return false' is preventing the form from submitting via document.thisForm.submit(); as well as when the user clicks the submit button.
I commented these lines in j query.form.js then every thing works fine for me. Don't ask me the reason even i don't have the solution for that but it works for sure.
if (io.contentWindow.document.execCommand) {
try { // #214
io.contentWindow.document.execCommand('Stop');
} catch(ignore) {}
}
let me start by saying it may look simple but im finding it extremely difficult.
ive made a search script that uses PHP and to fetch a result would look like this
search.php?term=alice&submit=Submit
Standard stuff.. problem is, i use an SPI with AJAX and PHP so my results would have to load dynamically into a div, whilst still keeping the hash value, as not to lose the page the user had visited previous to searching.
jQuery.history.js is the plugin i use for back button support, which requires links to be like such:
Home Page
this would load 'home.html' into a div named pageContent. as far as i know theres no way to call php files unless you develop a little hack, which i have,
here is my JavaScript/jQuery for my search form:
<script language="JavaScript">
$(document).ready(function() {
// bind form using ajaxForm
$('#search1').ajaxForm({
// target identifies the element(s) to update with the server response
target: '#pageContent',
// success identifies the function to invoke when the server response
success: function() {
$('#pageContent');
var hash = '#search.php?term='+($('#query').val()+'&submit=Submit').replace(/ /g, '+');
var stripped = hash.replace(/(<([^>]+)>)/ig,"");
update(window.location.hash = stripped);
}
});
});
</script>
Heres the form:
<form id="search1" action="search.php" method="post">
<input id="query" type="text" name="term" />
<input type="submit" name="submit" value="Submit" />
</form>
My problem is this:
ive tried this.form.reset(); this: Resetting a multi-stage form with jQuery , yet none of this works. please help me if you know a way of doing this..
$('#query').val(DefaultValue);
with this u can set your value to whatever you want, like blank: '';
I want to trigger the submit event of the form the current element is in. A method I know works sometimes is:
this.form.submit();
I'm wondering if there is a better solution, possibly using jQuery, as I'm not 100% sure method works in every browser.
Edit:
The situation I have is, as follows:
<form method="get">
<p><label>Field Label
<select onchange="this.form.submit();">
<option value="blah">Blah</option>
....
</select></label>
</p>
</form>
I want to be able to submit the form on change of the <select>.
What I'm looking for is a solution that works on any field within any form without knowing the id or name on the form. $('form:first') and $('form') won't work because the form could be the third on the page. Also, I am using jQuery on the site already, so using a bit of jQuery is not a big deal.
So, is there a way to have jQuery retrieve the form the input/select/textarea is in?
I think what you are looking for is something like this:
$(field).closest("form").submit();
For example, to handle the onchange event, you would have this:
$(select your fields here).change(function() {
$(this).closest("form").submit();
});
If, for some reason you aren't using jQuery 1.3 or above, you can call parents instead of closest.
this.form.submit();
This is probably your best bet. Especially if you are not already using jQuery in your project, there is no need to add it (or any other JS library) just for this purpose.
I have found that using jQuery the best solution is
$(this.form).submit()
Using this statement jquery plugins (e.g. jquery form plugin) works correctly and jquery DOM traversing overhead is minimized.
Similar to Matthew's answer, I just found that you can do the following:
$(this).closest('form').submit();
Wrong: The problem with using the parent functionality is that the field needs to be immediately within the form to work (not inside tds, labels, etc).
I stand corrected: parents (with an s) also works. Thxs Paolo for pointing that out.
You can always JQuery-ize your form.submit, but it may just call the same thing:
$("form").submit(); // probably able to affect multiple forms (good or bad)
// or you can address it by ID
$("#yourFormId").submit();
You can also attach functions to the submit event, but that is a different concept.
Your question in somewhat confusing in that that you don't explain what you mean by "current element".
If you have multiple forms on a page with all kinds of input elements and a button of type "submit", then hitting "enter" upon filling any of it's fields will trigger submission of that form. You don't need any Javascript there.
But if you have multiple "submit" buttons on a form and no other inputs (e.g. "edit row" and/or "delete row" buttons in table), then the line you posted could be the way to do it.
Another way (no Javascript needed) could be to give different values to all your buttons (that are of type "submit"). Like this:
<form action="...">
<input type="hidden" name="rowId" value="...">
<button type="submit" name="myaction" value="edit">Edit</button>
<button type="submit" name="myaction" value="delete">Delete</button>
</form>
When you click a button only the form containing the button will be submitted, and only the value of the button you hit will be sent (along other input values).
Then on the server you just read the value of the variable "myaction" and decide what to do.
In JQuery you can call
$("form:first").trigger("submit")
Don't know if that is much better. I think form.submit(); is pretty universal.
<form method="get">
<p><label>Field Label
<select onchange="this.form.submit();">
<option value="blah">Blah</option>
....
</select>
</label>
</p>
**<!-- <input name="submit" type="submit" /> // name="submit_new_name" -->**
</form>
<!--
this.form.submit == this.form.elements['submit'];
-->
