I have a button example below
<button id="startrunning">go</button>
There is no form or anything I'm using on the same page java script to detect it's click. It will work like I want it to when I click it. I want to see when the page is loaded it will automatically submit it's self is there a way?
Thank you
jsFiddle: http://jsfiddle.net/QEu84/10/
<script type="text/javascript">
function submit()
{
document.getElementById("startrunning").click(); // Simulates button click
document.submitForm.submit(); // Submits the form without the button
}
</script>
<body onload="submit()">
<form id="submitForm">
<button id="startrunning">go</button>
</form>
</body>
You can automatically click it when the page loads, using the code below, but you need a form to submit something (you submit a form, not a button)
<body onLoad="document.getElementById('startrunning').click();">

I'm working with an embedded app on our dev site and when I click the submit button inside the iframe, I am triggering a manual submission event on another form (not in an iframe) on that page. If I manually click the submit button for the form, my data posts and everything works correctly. However, I want to eliminate an extra user click and submit the external form automatically when a user submits the other form inside the iframe.
I've got everything working correctly on a base level. When a user clicks the submit button in the iframe, I am using JQuery to grab values from inside the iframe and set values in this external form. Using the jquery 'submit()' event, I am then able to submit that external form. The problem is, the page refreshes and the data doesn't go anywhere. If I remove the 'submit()' event and manually click the submit button, the form posts and in this case, adds a product with custom data to the product cart.
As a proof of concept, this is my 'iframed' HTML.
<!DOCTYPE html>
<html>
<head></head>
<body>
<h1>Proof of Concept</h1>
<p>Total cost: $<span id="cust_price">222.22</span> plus shipping.</p>
<p>Quote number: <span id="quot_num">1546751962211</p>
<form method="POST" enctype="multipart/form-data" id="newQuoteForm">
<button type="submit" class="btn btn-primary" name="new-app-btn">Add to Cart</button>
</form>
</body>
<footer>
</footer>
</html>
Here is my on-page form that is OUTSIDE the iFrame.
<form method="POST" enctype="multipart/form-data" id="outer-quote-form" action="/checkout/">
<label class="quote_number">Quote Number:
<input type="text" id="quote_number" name="quote_number" value="">
</label>
<label class="custom_price">price:
<input type="text" id="custom_price" name="custom_price" value="">
</label>
<button type="submit" class="btn btn-primary" name="ws-add-to-cart">Add to Cart</button>
</form>
Then, I have JQuery working to grab the iframed values and puts them in the exterior form. Afterwards, it fires a 'submit()' event on that form.
<script>
jQuery('#newQuoteApp').load(function() {
var iFrameDOM = jQuery("iframe#newQuoteApp").contents();
jQuery('#newQuoteApp').contents().find('#newQuoteForm').submit(function() {
jQuery("input#custom_price").val(jQuery('#newQuoteApp').contents().find('#cust_price').text()); // updated
jQuery("input#quote_number").val(jQuery('#newQuoteApp').contents().find('#quot_num').text());
jQuery("#outer-quote-form").submit();
return true; //return false prevents submit
});
});
</script>
Except when the jquery submit() event fires, the form appears to submit and the page refreshes but no data is posting as it does when I manually submit the form. Is there an extra step here or a better way to fire the form submit with post data?
Edit: Adding the PHP function that isn't firing on jquery submit() for context.
if (isset($_POST['ws-add-to-cart'])) {
add_action( 'init', 'add_product_to_cart' );
function add_product_to_cart() {
global $woocommerce;
global $product;
$product_id = 138;
$woocommerce->cart->add_to_cart($product_id);
}
header("Location:https://www.devsite.com/checkout/");
}
The reason for the form not submitting because you are submitting the whole form without the submit button which is <button type="submit" class="btn btn-primary" name="ws-add-to-cart">Add to Cart</button> which you have declared in php to get a post request like this
if (isset($_POST['ws-add-to-cart'])) {...
When you call submit(); on the form via the get method, you see '/new-quote/?quote_number=1546751962211&custom_price=222.22'
but where's ws-add-to-cart, it's not submitting and that's the reason why php isn't getting your request
The fix will be to add .click() on the submit button instead of submitting the form
<script>
function enterVals($val){
var price = $val.price;
document.getElementById("quote_number").value = $val.num
document.getElementById("custom_price").value = $val.price
document.getElementsByName("ws-add-to-cart").click();
}
</script>
Or in your script in case you want to use jquery, this is the fix
<script>
jQuery('#newQuoteApp').load(function() {
var iFrameDOM = jQuery("iframe#newQuoteApp").contents();
jQuery('#newQuoteApp').contents().find('#newQuoteForm').submit(function() {
jQuery("input#custom_price").val(jQuery('#newQuoteApp').contents().find('#cust_price').text()); // updated
jQuery("input#quote_number").val(jQuery('#newQuoteApp').contents().find('#quot_num').text());
jQuery("button[name=ws-add-to-cart]").click();
return true; //return false prevents submit
});
});
</script>
This is definitely the answer and sorry for my stupidity, i didn't pay required attention before
try removing return true from your js code
if that doesn't work, try changing the <form method="POST" to <form method="GET" to debug the values in the url just for checking that the form actually fires up with values
Alternative method: Old school method
code for page OUTSIDE the Iframe
<script>
function enterVals($val){
var price = $val.price;
document.getElementById("quote_number").value = $val.num
document.getElementById("custom_price").value = $val.price
document.getElementById("outer-quote-form").submit();
}
</script>
code for the Iframe file
<script type="text/javascript">
$('#newQuoteForm').on('submit', function(event) {
var Page = window.parent;
var allVals = {
price:$('#cust_price').text(),
num:$('#quot_num').text()
}
Page.enterVals(allVals);
event.preventDefault();
});
</script>
Explanation
window.parent refers to the parent window where the iframe is loaded on, with reference to this we can trigger functions that are in the parent window so by this, we created a variable and added the information which is sent by the function enterVals() to the window
The enterVals() function just puts the values and submits the form without any jQuery.
What is the proper way to submit a form with JS?
This might not be the 'best' way to submit a form with js but is cross-browser which is good
I have a web-form written in ASp.Net MVC5 which is used to gather some details from the user. However, before I get them to submit the form, I want them to have the option to look at another web-page (in a new window or tab) which gives them more information if they need it prior to submitting the page. To that end, on the web-form, I have a form with the following buttons:
<form action="/Application/MyAction" method="post" id="myForm">
// various fields ...
<button onclick="getMoreInfo()">More Information</button>
<button type="button">Submit Form</button>
</form>
Then, at the bottom of the page I have the following javascript defined:
<script>
function getMoreInfo()
{
var urlToUse = 'http://some-other-page.html';
window.open(urlToUse);
return false; // trying to stop the form submission from occurring
}
</script>
My problem is that when this "More Information" button is clicked, it has the effect of submitting the form [which I don't want to do yet] - since there is a separate submit button for doing that task. Is there a way to use a button to jump to another page without actually submitting the current form?
thanks heaps,
David.
I found that answer #3 at this question helped me:
How do I cancel form submission in submit button onclick event?
My solution was to change the code thus:
I changed the button code to look like this:
<form action="/Application/MyAction" method="post" id="myForm">
// various fields ...
<button id="moreInformationButton" >More Information</button>
<button type="button">Submit Form</button>
</form>
And then I changed the javascript to look like this:
$("#moreInformationButton").click(function (event) {
event.preventDefault(); // This stops the submit form being triggered
var urlToUse = 'http://some-other-page.html';
window.open(urlToUse); // open the help page
});
This allowed me to open up another window or tab with more information without actually submitting the form.
I have been building a chrome extension and I have been using content scripts to listen for the form submit event. I was testing my extension and it works pretty well, until I tested on a site that didn't work. The reason it didn't work is because the form button isn't really a form button with the submit action. It's actually an <a> tag with an href tag that links to "javascript:;", so the submit event doesn't trigger. The link is inside a form, it's just not a button tag with the submit action. How can I make sure that my content script triggers whenever a user tries to submit a form?
It seems simple at a glance, but there's no surefire way to achieve what you're asking.
Consider this:
document.getElementById('myform').addEventListener('submit', function(e) {
e.preventDefault();
console.log(document.getElementById('sometext').value);
console.log('form submitted');
});
document.getElementById('notasubmitbutton').addEventListener('click', function(e) {
console.log(document.getElementById('sometext').value);
});
<form id="myform">
<input type="text" id="sometext">
<input type="submit">
<button id="notasubmitbutton" type="button">Submit 2</button>
</form>
There's the regular submit button that will trigger the submit event. Then there's another button, that will just collect all the data from the form, but will not submit it in the traditional sense.
There's absolutely no way you could foresee all the possible ways someone could build their form, so what you're asking for can't be done.
I have the following piece of code:
<form name="ProjectButtonBar_deleteProject_LF_3" action="" method="post">
<a class="buttontext" href="javascript:document.ProjectButtonBar_deleteProject_LF_3.submit()">...</a>
As you can see, clicking the link causes "hard" submit of the form. Instead of this, I would like to trigger submit event. It is so, because in another file there is a code executed in reaction to submit event. With the code shown in this example, this code is being ignored. I can't change the href attribute by hand, beause whole "a" tag is generated by framework.
How should I do this using jQuery? I suppose I have to modify href somehow, but how? Or maybe there is another solution?
Instead of triggering the click event on the submit button, use jQuery to trigger the submit action on the form.
$('form').trigger('submit');
This will trigger any event that's been attached to the form via .on('submit')
Using jquery you can do it easily:
<form name="ProjectButtonBar_deleteProject_LF_3" id="form1" action="" method="post">
<input type="submit" id="btnSubmit"/>
</form>
<a class="buttontext">...</a>
$('.buttontext').on('click',function(e){
e.preventDefault();
$('input#btnSubmit').click();
});
or submit form programmatically:
$('.buttontext').on('click',function(e){
e.preventDefault();
$('form#form1').submit();
});
i am trying to load a html page with the results of a "get" from another link.The idea is when I open the page, I should see the results of the get displayed.
I tried the following with javascript but with no success. The problem is I always get a submit button on the page. I want the submit to be "pre" done!
Please help. Here is what I have:
<body onLoad ="subMe()">
<script>
function subMe(){
document.getElementById("formButton").submit();
}
</script>
<div align="center">
<div style="display: hidden;">
<form action="http://localhost:8000/getusers/" method="get">
<input type="submit" id="formButton" />
</form>
</div>
..
</body>
Any idea? This is linked to my previous post:Cgi C program return value to main HTML and display result
The problem is that you are submitting a button, not the form.
Try:
function subMe() {
document.getElementsByTagName('form')[0].submit();
}
Since you have no need for the submit button, there is also no harm in removing it from the html.
I believe that you have to submit the form, not the button.
document.getElementsByTagName('form')[0].submit();
submit() should be called on the form element, not on a submit button.
