I have following simple HTML Form & i tried to submit the form automatically during page load.
Below Javascript code is not automatically submitting the form.
HTML :
<form action="SSL.php" method="POST" name="TForm" id="transactionForm">
<input type="hidden" name="merchantTxnId" id="merchantTxnId" value="test">
<input type="submit" name="submit" id="submit" value="submit" style="visibility:hidden">
</form>
Redirecting ... Please wait...
Java script:
<script>
window.onload = function(){
alert(1); // this is working..
document.getElementById("transactionForm").submit(); //nothing is happening with this line . form is not getting submitted
}
</script>
I found following error in Chrome console mode says:
Kindly suggest me where the problem is...
You may not use submit as the name or id of any of your form elements.
The reason is, that you can reach each child of your form via document.getElementById('form').nameOfTheChild where nameOfTheChild is the name of the child. If you have a child with the name submit, document.getElementById('form').submit is a shortcut to address that child.
The documentation of .submit() says that :
Forms and their child elements should not use input names or ids that
conflict with properties of a form, such as submit, length, or method.
Name conflicts can cause confusing failures.

I am trying to get a hyperlink element to act as a form submit button. This sort of question has been answered multiple times over the years but, for some reason, I am not able to get it to work even with cut-n-pasted code and I'm wondering if I'm missing something trivially simple that my eyes are too bugged out to see. The full code is here:
<html>
<head>
<script language="JavaScript" type="text/javascript">
<!--
function signup() {
alert("Form is " + document.signup_form);
document.signup_form.submit() ;
}
-->
</script>
</head>
<body>
<?php
echo("Submit is [" . $_POST['submit'] . "]");
?>
<form method="post" name="signup_form" id="signup_form" action="" >
<input type="text" name="from_email" placeholder="e-mail address"><br>
<input type="submit" name="submit" value="Send Email">
Sign Up!<br>
</form>
</body>
</html>
The input submit element ("Send Email") works fine. The hyperlink ("Sign Up!") also works fine and calls the javascript function so that the alert() box in the function shows up.
So, it's just the submit() call that's not doing anything--I even printed out document.signup_form in an alert() box to confirm that it's defined (it is). So what am I missing here?
Thanks for any help!
There is a weird thing with how forms work with Javascript - each field is accessible by using formElement.fieldName. Unfortunately, that means that if you name a field input submit, all of a sudden the built-in formElement.submit() function is replaced by your input element. So in your code, document.signup_form.submit() is failing because it is calling the element, not the method, and you can't call an element as a function. See this SO QA for details.
The fix is easy - change:
<input type="submit" name="submit" value="Send Email">
to:
<input type="submit" name="submitBtn" value="Send Email">
Also, as others have noted, you will want to give your form a valid action. Also, in general it might be preferred to access things by id (document.getElementById()) instead of by things like document.signup_form.
Your <form> element is missing a value in it's action attribute. Quoting the specs:
You also have to specify the URL of the service that will handle the
submitted data, using the action attribute

Require attribute on the input field doesn't work when i implement google recaptcha. When the input is empty, the form is supposed not to be submitted. But the form gets submitted when input is empty. I followed google's guide to implement that in its simplest form.
<?php if (isset($_POST['code']) && ($_POST['code'] == "whatever")) //do stuff?> ?>
What i want to do is to make the recaptcha execute only when the input is not empty, else prevent form submit and recaptcha execution.
<form id="form1" method="post" >
<input name="code" type="text" required>
<button data-sitekey="xxx"
data-callback='onSubmit' type="submit" class="g-recaptcha" >Let me in</button>
</form>
</div>
<script>
function onSubmit(token) {
document.getElementById("form1").submit();
}
</script>
<script src="https://www.google.com/recaptcha/api.js" async defer></script>
Looking over the documentation you linked to, you are probably better off getting rid of the required attribute and adding a check to your script to not submit the form if the I put field is null.
So JavaScript would be checking if the field is empty and then give a validation alert or however works best for your situation.
The reason it submits is your JavaScript function is calling submit directly, which is bypassing the HTML5-only validation. The submit button being a type of 'submit' will do the submission for you automatically so you don't need it.
I have many forms in a webpage.
Form id is given by php like:
<FORM method="post" id="<?php echo $idform;?>">
In every form the submit button is:
<input name="inoltro" value="Book" type="button" onclick="mySubmit(<?php echo $idform;?>)">
Submit function is:
function mySubmit(FormToSubmit)
{
show_message();
document.getElementById(FormToSubmit).submit();
}
Console javascritp error says it cannot submit null form.
Where am I wrong?
many thanks for your kind help
You can get form object in on* events by passing this.form as a parameter.
Just like that:
function mySubmit(form) {
console.log(form);
}
<form method="post" action="?">
<input type="text" name="test">
<input type="button" name="inoltro" value="Book" onclick="mySubmit(this.form)">
</form>
Press Ctrl+Shift+J in Chrome to see developer's console.
The form you are trying to submit does not exist ...
please check again you are echoing correct values in id attribute of the form ...
onclick="mySubmit('<?php echo $idform;?>')"
make sure this code is outputting something ... use google chrome's inspect element to check the echoed values
I have two forms. I want to submit both forms with 1 button. Is there any method that can help me do it?
Example:
<form method="post" action="">
<input type="text" name="something">
</form>
<form method="post" action="">
<input type="text" name="something">
<input type="submit" value="submit" name="submit">
</form>
I want both forms to be submitted with 1 submit button. Any help would be appreciated.
The problem here is that when you submit a form, the current page is stopped. Any activity on the page is stopped. So, as soon as you click "submit" for a form or use JavaScript to submit the form, the page is history. You cannot continue to submit another page.
A simplistic solution is to keep the current page active by having the form's submission load in a new window or tab. When that happens, the current page remains active. So, you can easily have two forms, each opening in a window. This is done with the target attribute. Use something unique for each one:
<form action='' method='post' target='_blank1'>
The target is the window or tab to use. There shouldn't be one named "_blank1", so it will open in a new window. Now, you can use JavaScript to submit both forms. To do so, you need to give each a unique ID:
<form id='myform1' action='' method='post' target='_blank1'>
That is one form. The other needs another ID. You can make a submit button of type button (not submit) that fires off JavaScript on click:
<submit type='button' onclick="document.getElementById('myform1').submit();document.getElementById('myform2').submit();" value='Click to Submit Both Forms'>
When you click the button, JavaScript submits both forms. The results open in new windows. A bit annoying, but it does what you specifically asked for. I wouldn't do that at all. There are two better solutions.
The easiest is to make one form, not two:
<form action='' method='post'>
<input type='text' name='text1'>
<input type='text' name='text2'>
<input type='submit' value='Submit'>
</form>
You can place a lot of HTML between the form tags, so the input boxes don't need to be close together on the page.
The second, harder, solution is to use Ajax. The example is certainly more complicated than you are prepared to handle. So, I suggest simply using one form instead of two.
Note: After I submitted this, Nicholas D submitted an Ajax solution. If you simply cannot use one form, use his Ajax solution.
You have to do something like that :
button :
<div id="button1">
<button>My click text</button>
</div>
js
<script>
$('#button1').click(function(){
form1 = $('#idIFirstForm');
form2 = $('#idISecondForm');
$.ajax({
type: "POST",
url: form1.attr('action'),
data: form1.serialize(),
success: function( response ) {
console.log( response );
}
});
$.ajax({
type: "POST",
url: form2.attr('action'),
data: form2.serialize(),
success: function( response2 ) {
console.log( response2 );
}
});
});
</script>
You could create a pseudo form in the background. No time to write the code, jsut the theory. After clicking submit just stop propagation of all other events and gather all the informations you need into one other form you append to document (newly created via jquery) then you can submit the third form where all the necesary infos are.
Without getting into why you want to use only 1 button for 2 forms being submitted at the same time, these tools that will get the input data available for use elsewhere:
Option 1...
Instead of using <form> - collect the data with the usual Input syntax.
ex: <input type="text" name="dcity" placeholder="City" />
Instead of using the form as in this example:
<form class="contact" method="post" action="cheque.php" name="pp" id="pp">
<label for="invoice">Your Name</label>
<input type="text" id="invoice" name="invoice" />
<button class="button" type="submit" id="submit">Do It Now</button>
</form>
use:
<label for="invoice">Your Name</label>
<input type="text" id="invoice" name="invoice" />
<button type="button" onclick="CmpProc();" style="border:none;"><img src="yourimage.png"/> Do It Now</button>
Then code the function CmpProc() to handle the processing/submittion.
Inside that function use the Javascript form object with the submit() method as in...
<script type="text/javascript">
function submitform() {
document.xxxyourformname.submit();
}
</script>
Somehow I suspect making the two forms into one for the POST / GET is worth reconsidering.
Option 2...
Instead of POST to use the data to the next page consider using PHP's $_SESSION to store each of your entries for use across your multiple pages. (Remember to use the session_start(); at the start of each page you are storing or retrieving the variables from so the Global aspect is available on the page) Also less work.
Look man. This is not possible with only HTML. weither you gether the inputs in one form or else you use jquery to handle this for you.
I have a JSP page which is included in the main page..Within the JSP page, I have given a HTMLform which I want to submit() once the user clicks it using Jquery?
<form id="orderBean1" name="myForm" action="/Auto/Item" method="post">
<input id="filename" name="filename" value="" />
</form>
First,
Suprisingly, this form is not recognized within the page..
When I give $('#orderBean1') in my console it does not give the form object whereas $('#filename') gives me the filename input element.
Second ,
As the form is not recognized it does not get submitted...
$("#vehreport").click(function(e) {
e.preventDefault();(I have given this stmt even after the submit() and still not working...
$("#orderBean1").submit();
alert("formsubmnittted");
})
Question -
Why doesn't the form element is recognized in my page?
I set up a JSbin here.
As you can see, #orderbean1 is recognized, and submits.
The error is likely elsewhere is your JS or markup, though if I'm misunderstanding the question please clarify
