I have a form that uploads a file and targets an iframe on the page. When the user clicks submit, I want the file contents to "clear" out.
I tried this
$('#imageaddform').submit(function(){
$('#imagefile').val('');
});
But it clears the form before the submit, so nothing is ever uploaded.
Is how do I clear after submit?
If you have no other handlers bound, you could do something like this:
$('#imageaddform').submit(function(e) {
e.preventDefault(); // don't submit multiple times
this.submit(); // use the native submit method of the form element
$('#imagefile').val(''); // blank the input
});
Lonesomeday's solution worked for me but for Google Chrome I found it would still submit empty form data unless I added a timeout like this:
$('#imageaddform').submit(function(e) {
e.preventDefault(); // don't submit multiple times
this.submit(); // use the native submit method of the form element
setTimeout(function(){ // Delay for Chrome
$('#imagefile').val(''); // blank the input
}, 100);
});
You could do something like this:
$('#imageaddform').submit(function(){
setTimeout(function() {
$('#imagefile').val('');
},100);
});
How are u submitting the form? if this is normal form post then then page wont exist in that case i am wondering if u are looking to clear the form before the page refreshses so that when the user comes back he doesn't see the values populated.
If the form is submitted by ajax then you can
function(){
$('form1')[0].submit();
clearForm();
}
Did i miss the question?

I have two ways of using form on a page.
First one is standard way when user types something in input field and clicks the submit button.
Second one is that the form is automatically filled and submitted depending on if a query string is passed to a page. (www.website.com/contact?fillform=true)
Everything works fine except I need yet to trigger the submit button for when query string is passed but currently it just refreshes the page.
I have done part in PHP, I have checked variables and they are ok.
Here is Codepen, e.preventDefault() is commented out since it doesn't work on window load
$(window).load(function() {
// Function for submitting form
function submitForm(e) {
console.log('I am in');
e.preventDefault();
jQuery.ajax({
... // Submit form
})
}
// Normal way of submitting form, works ok
$contactForm.on('submit', function(e) {
submitForm(e);
});
// This should trigger form automatically
if(fillFormAutomatically) {
// Everything so far works ok
// I just need to trigger form without page refresh but none of these works
$submitBtn.trigger('click');
$submitBtn.triggerHandler('click');
$contactForm.submit(e);
$contactForm.submit(function(e) {
console.log(e); // nothing in console shows here
submitForm(e);
});
submitForm(); // This triggers function but I can't pass event?
}
});
I think there is a couple of problems.
.load() was depreciated in jQuery 1.8, so don't use that. See: https://api.jquery.com/load-event/
Secondly, when you call submitForm() on window.ready(), there is no event. So you're trying to call .preventDefault() on undefined. Just move it to the .submit() function.
Does that answer your question?
$(window).ready(function() {
var $form = $("#form");
var $submitBtn = $("#submitBtn");
// Send form on window load
submitForm();
// Normal way
$form.submit(function(e) {
e.preventDefault();
submitForm(e);
});
// Send form
function submitForm() {
$('#vardump').append('Sending form...');
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form action="" id="form">
<input type="text" value="Somedata">
<button id="submitBtn">Submit</button>
</form>
<div id="vardump"></div>
I'm facing a sort of dummy problem.
On my site there is an order form (simple html form) and I noticed that I get double commands from time to time.
I realized that if I clicked repeatedly few times the submit button (before the action page is loaded) I got as many commands as I have clicked.
So I wonder if there are simple solution to make form submission asyncronous?
Thanks
P.S. I added JQuery UI dialog on submit "wait please..." but I get still double commands.
UPDATE
As GeoffAtkins proposed I will:
disable submit after dialog is shown
make use of unique form's token (as it is already added by Symfony) Do not use Symfony token as unique form token as it is always the same for current session. Use just random or something like that.
I would consider doing this (jQuery since you said you used that)
$(function() {
$("#formId").on("submit",function() {
$("#submitBut").hide();
$("#pleaseWait").show();
});
});
if you submit the form and reload the page.
If you Ajax the order, then do
$(function() {
$("#formId").on("submit",function(e) {
e.preventDefault();
var $theForm = $(this);
$("#submitBut").hide();
$("#pleaseWait").show();
$.post($(this).attr("action"),$(this).serialize(),function() {
$theForm.reset();
$("#submitBut").show(); // assuming you want the user to order more stuff
$("#pleaseWait").hide();
});
});
});
NOTE that disabling the submit button on click of the submit button may stop the submission all together (at least in Chrome): https://jsfiddle.net/mplungjan/xc6uc46m/
Just disable the button on click, something like:
$("#my-button-id").on("click", function() {
$(this).attr("disabled", "disabled");
});
var bool = true;
function onclick()
{
if(bool)
{
//do stuff
bool = false;
}
else
{
//ignore
}
}
You could disable the button on the form when it is clicked, and then continue to perform the action. You would probably change the text to say "loading..." or some such.
You may also want to re-enable the button on fail or complete of the ajax request.
I've done this many times similar to this: https://stackoverflow.com/a/19220576/89211
For now it seems to work without problems but I was wondering...Let's say you have multiple forms (each on a different page) with each and one of them a different id.
Each form has a button with and id "btnSave". In the masterpage (template) I added all links to the ajax-formhandling-scripts working like this:
$(document).ready(function() {
// ignore the submit
$("#frmNews").submit(function() {
return false;
});
// catch the click-event
$("#btnSave").on("click", function() {
// input control
// ajax-request if input was ok
}
});
Before I continue to build I want to know sure using the same button-id won't give me problems. Am I working wrong here?
Repeated id attribute values are invalid - they must be unique. Use a class instead. Also, from a design point of view you should hang all logic off the submit event of the form. Try something like this:
$(document).ready(function() {
// ignore the submit
$(".frmNews").submit(function(e) {
// input control
if (input_control_ok) {
// $.ajax()...
}
else {
e.preventDefault(); // stop form submission
}
});
});
The .btnSave button should then have the type="submit" attribute added to it, assuming it doesn't already.
At management's request, I need to open the user's email client and submit a form on a button click. I initially had
window.location = "mailto:email#example.com";
as the callback to the click event for the submit input, but this doesn't work. It seems like the form submits to quickly.
Using window.open does work, but it creates a blank window that is undesirable.
I also had the idea to prevent and delay the form submission as in
window.location = "mailto:personalcounselor#gleim.com";
setTimeout(function () {
$(this).closest('form').trigger('submit');
}.bind(this), 1000);
e.preventDefault();
This also works, but it seems sketchy to me.
Is there any way to submit the form and open a mailto link at the same time?
I don't know if this will work, but I am sure with a bit of tweaking it should work and have the desired result which you are after (it was too long to fit in a comment, if it will not work I will gladly delete it!);
$("form").on("submit", function() {
window.onbeforeunload = function() {
window.location = "mailto:email#example.com";
};
});
Simply put when the form is submitted, set the onbeforeunload event to change the location to the mailto. I think doing it this way will only make the mailto open if the form is submitted rather than when a user just navigates away.
I don't know if this will work, or how hacky it is, but thought I would throw in my two cents!
UPDATE
On form submit, mailto from javascript with form values
This does seem to work and verified by others.
$("input[type=submit]").click(function(){
window.location.href = "mailto:email#example.com";
});
I have a confirm step in one of my pages.
Desired action:
user clicks 'submit' and an AJAX request is made that does the appropriate action and returns a confirm dialog
user 'confirms' and then the form is submitted using a standard post.
So for the first part I'm fine using the jQuery form plugin:
$('form').ajaxForm(...options...);
For the second part I'd like to submit the form again, but non-ajax. Basically I want to do this:
$('form').submit();
And have it do an actual browser post. The problem is that $('form').submit() just triggers the ajax submit.
Is there a way to use the form for both purposes?
$('forms-submit-button').click()
..does that work , for the second submit?
:) :)
Can't you just unregister the submit event handler after you've ajax-posted the results? Why do you need to post the same data twice, by the way? If the data haven't changed between the Ajax post and the regular one, why is the regular one needed?
You can try to change a value in the form (se some hidden value to 1), do another ajax request and finally do a redirect. It's not the same but it should work.
Note that it's very strange to submit the same data twice though..

$('forms-submit-button').click() ..does that work , for the second submit?
form onsubmit='ajaxCheck();'
...
/form
script
var ajaxCheck = function()
{
//do check
return confirm(); // if ok form submit normaly / if cancel form doesn't submit
}
/script
or something with a flag:
var flag = true;
var firstCheck = function()
{
if( flag )
{
//do the ajax Call which will fire an event,
// let's call it onData
$.post(url,{param1:val1,...,paramN:valN},onData);
return false;
}
return true;
}
var onData = function (data)
{
flag = !confirm(...);
//if user click ok and try to re-submit the form
//this time will just go
}
