In one of my webpage i need to add PayPal payment button, in which value has to be entered by input.
i got this script to add PayPal button:
<script
async="async" src="https://www.paypalobjects.com/js/external/paypal-button.min.js?merchant=email#adress.com"
data-button="paynow"
data-amount="5"
data-currency="USD">
</script>
Now i have to change the value of "data-amount" every time by Input from User.
I tried to use onkeyup, setAttribute but both don't seem to work. Please suggest what should i do or where i'm making mistake.
<!DOCTYPE html>
<html>
<script>
function showMe(e) {
var x=e.value;
document.getElementsById("paypal").setAttribute("data-amount", "x");
}
</script>
<body>
Amount: <input type="number" name="amount" id="amount" onkeyup="showMe(this)" required>
<script id="paypal"
async="async" src="https://www.paypalobjects.com/js/external/paypal-button.min.js?merchant=payPalmerchantId"
data-button="paynow"
data-currency="USD">
</script>
<br><br><br>
<p>You will be redirected to Payment Gateway..</p>
</body>
</html>
try this..
function showMe(e) {
var x=e.value;
$("#paypal").attr("data-amount", x);
}
or doing everything in jquery
$("#amount").on('input', function() {
$("#paypal").attr("data-amount", $("#amount").val());
});
I'm not familiar with PayPal scripts, but as I know, such types of embedding set attributes and any other features at step of initializing...
So you have to reload your script.
You could also search for the ability to change attributes with the help of API provided by PayPal
Update:
I've just tried to insert your code into my local page...
Your script searches for element with id "paypal", but if you look at your code after tha page loads, you won't see even "script" tag which refers to the paypal js file. You'll see a form instead. Try to search for "script" word here and you won't find that tag. At least this reason is why your script doesn't work.

I'm very new to coding, so please forgive me if this is a dumb question.
I'm working on an assignment where I have to add functionality and styles to an existing bootstrap HTML doc. The purpose is to allow people to enter a dollar amount into an input field either by typing in an amount or by clicking buttons that populate the field with set amounts. One of my instructions was to update the donate submit button so that it appends the chosen donation amount to the "/thank-you" URL.
This is what I have for the input field:
<form id="amountSend">
<input type="text" class="form-control donation-amount-input" placeholder="Other" id="other-amount"/>
</form>
This is what I have for the button:
<button id="donateBtn" type="submit" action="/thank-you"
method="get">DONATE<span class="metric-amount"></span></button>
And I was thinking that the jQuery would look something like this, though the submit function is not currently giving me any visible results.
$("#donateBtn").click(function() {
if (!$.isNumeric($("#other-amount").val())) {
$("#dataWarning").show();
$(".metric-amount").hide();
$(".metric-message").hide();
} else {
$("#amountSend").submit(function() {
var url = "/thank-you";
$(".metric-amount").appendTo("url");
});
}
})
I also got some decent results using a PHP method:
<form id="amountSend" method="post" action="/thank-you.php">
<input type="text" class="form-control donation-amount-input" placeholder="Other" id="other-amount" name="donation"></input>
</form>
<button id="donateBtn" type="submit">DONATE<span class="metric-amount"></span></button>
<script>
$("#donateBtn").click(function() {
if (!$.isNumeric($("#other-amount").val())) {
$("#dataWarning").show();
$(".metric-amount").hide();
$(".metric-message").hide();
} else {
$("#amountSend").submit();
}
});
</script>
This one will open the PHP file I set up (/thank-you.php, which i have stored just in the same root folder as my main HTML doc), but all the browser gives me is the raw HTML code of the PHP file. Here's the code I have in the PHP file:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Untitled Document</title>
</head>
<body>
Thank you for your donation of
<?php echo $_POST["donation"]; ?><br>
</body>
</html>
Anyway, I guess I'm wondering if I'm on the right track? Should I pursue the jQuery or PHP method? Can I even do this using only jQuery? I've seen a few posts on this subject already, but I thought I'd make a new one since the ones I've seen are all fairly vague, I haven't seen the same answer twice, and I'm not sure I fully understand exactly what I'm trying to accomplish, in terms of a visual confirmation of results.
Thanks!
First of all, you have several issues with your code.
Number one: The formulary you have there is bad coded, the form tag needs to have the action and method attributes, not the submit button.
And in top of that, the submit button needs to be inside the form tag, if is not in there, it will not have and kind of effect.
Number two: If you are gonna submit the formulary to a php file and handle the request there ,you need the file to be running on a server (local or whatever). PHP is a server language, if you open the file directly in a browser, it will show you the code it has inside and will not work.
Hope it helps!
I am new to java script. I have created an input which is requires the user to input some text to enable the submit button.
<input class="param" name="test" id="test" required ng-model="test">
How can I fill in the input text box using Java Script so I can submit the form (as if the user has entered the text). Currently, when I use for example the following script to update the value, the submit button on the form is not active.
document.getElementById("test").value =1
Could you update the attribute that ng-model is bound to? That should apply the value to the text field correctly.
I have created this example code:
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript">
function updateValue() {
document.getElementById("test").value = 'test';
}
window.onload = function () {
updateValue();
}
</script>
</head>
<body>
<form action="" method="post">
<input type="text" id="test" name="test" required>
<input type="submit" value="Okay">
</form>
</body>
</html>
This is what Phani Kumar M and Claies were asking for. I tested it on Windows 10 in Firefox 55.0.3 and Chrome 60.0.3112.113. In both browsers it works correctly. The form can be submitted without adding anything to the field.
Others can check other platforms. As mentioned, the required attribute will not work in Safari.
Your problem is somewhere else. I don't know anything about AngularJS, which you seem to be using without even mentioning it, but it might be there.
Let's keep this short and sweet.
Here is my header:
<head>
<title>4JSB Assignment</title>
<link rel="stylesheet" type="text/css" href="css/style.css">
<script type="text/javascript" src="javascript/form.js"></script>
</head>
Note: <script type="text/javascript" src="javascript/form.js"></script>
Does not appear to be working.
I have a Submit button in the body that is part of a form. Here it is, located at the end of the aforementioned form:
<input type=submit name="submitForm" id="submitForm" onclick="submitForm()">
Here is my external javascript:
function submitForm() {
alert("Working");
}
Alas, "Working" never appears.
My folder structure is as follows:
root
css
....style.css
javascript
....form.js
form.html
The answer is more than likely trivial, but has had me stuck on this assignment for hours because of this one requirement that the javascript be linked from an outside source. I appreciate any attempt to point out this mundane and unfortunate mishap to me.
The issue is that you have id="submitForm" and function submitForm
Not sure why browsers do this, but any id is available as a global object
so,
console.log(submitForm);
would show the input element, rather than the function!!
use a different name for the id, or for the function
console.log(submitForm) actually shows the function!! but it's still a name conflict in the end.
Try changing the name and id of your submit button to something like "submitButton" so that it isn't exactly the same as your javascript function. I believe there is a name conflict.
It depends on what do you want to acomplish:
If you add a onclick function on your submit button it wont work for submit the form, so it will be pointless to have it as that.
If you want execute a javascript function before submit the form and or want to perform some validations that may or may not prevent the form for being submitted . The best way to do it:
<form onsubmit="return submitform();">
....
<input type=submit name="submitFormAny" id="submitFormAny">
</form>
Also as other contributors were saying, be careful, you can't have elements and functions with same id's
I have written this code for Firefox:
<html><head><title>No</title>
<script type="text/javascript" src="jquery-1.4.2.js"></script>
</head>
<body>
<form action="javascript:void(alert('Yes'));">
<input type="submit" value="Submit">
</form>
<script>$($('form').submit())</script></body></html>
It correctly displays the alert box.
However, when i run this inside an iframe, with this code:
<html><body><iframe src="click.php"></iframe></body></html>
i don't get the alert box, not even if i click the submit button myself.
What is going on exactly? The same code works in Chromium
Well, don't do that then!
It doesn't make any sense to submit a form to a javascript: URL. Use a submit event handler to pick up the form submission and execute script, eg using jQuery:
$('#someform').submit(function() {
alert('Yes');
return false;
});
A good rule of thumb about when to use javascript: URLs is: never.
It looks like it's a problem with FF4 so I'll discuss it on their bugzilla if it's really their fault. I have modified the source so I'm not even sure it is a bug...
UPDATED - please read further details below original question
I have a select form element with various urls, that I want to open in a new window when selected - to do this I have the following code in the element's onchange event:
window.open(this.options[this.selectedIndex].value,'_blank');
This works fine. But I also want to submit the form when changing this select element value - I've tried various things, but I can't seem to get it to work.
I have jquery, so if it's easier to achieve via that then that's fine.
Update - I've just realised there is another issue with the above, because some of the urls are actually used to generate and output pdfs, and these do not work - they open and then immediately close (at least in IE7).
UPDATE 07/05/09 - I've now opened a bounty for this question as I really need to come up with a working solution. I did originally get around the issue by displaying links instead of a form select element, but this is no longer feasible.
The reason I need the above is that I have a large number of files that might need to be viewed / printed, too many to reasonably display as a list of links. I need to submit the form to record the fact a particular file has been viewed / printed, then display a log of the file history on the form - I'm comfortable with achieving this side of things, so don't require assistance there, but I thought it would help to place the context.
So, to clarify my requirements - I need a form select element and 'View' button that when clicked will not only launch a file download in a new window (note the above issue I faced when these files were PDFs), but also submit the form that contains the select element.
Here ya go
<script type="text/javascript">
$(function() {
$("#selectElement").change(function() {
if ($(this).val()) {
window.open($(this).val(), '_blank');
$("#formElement").submit();
}
});
// just to be sure that it is submitting, remove this code
$("#formElement").submit(function() {
alert('submitting ... ');
});
});
</script>
<form id="formElement" method="get" action="#">
<select id="selectElement">
<option></option>
<option value="http://www.deviantnation.com/">View Site 1</option>
<option value="http://stackoverflow.com/">View Site 2</option>
<option value="http://serverfault.com/">View Site 3</option>
</select>
</form>
You can use this.form.submit() to trigger the form submit:
<script language="javascript">
function myChangeHandler() {
window.open(this.options[this.selectedIndex].value, '_blank');
this.form.submit();
}
</script>
<select onchange="myChangeHandler.apply(this)">
...
</select>
Just tested Aron's example and it works fine, so I would suggest the error you are getting is from code outside of your onchange event. Try the below working example and see if you get the same error.
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
<HEAD>
<TITLE> Example onchange and submit </TITLE>
<script language="javascript">
function myChangeHandler()
{
window.open(this.options[this.selectedIndex].value, '_blank');
this.form.submit();
}
</script>
</HEAD>
<BODY>
<form id="myform1" action="test.html">
<select onchange="myChangeHandler.apply(this)">
<option>Please select....</option>
<option value="http://stackoverflow.com">Stackoverflow</option>
<option value="http://twitter.com">Twitter</option>
</select>
</form>
</BODY>
</HTML>
Basede on what you've described, your markup probably looks something like this:
<form ...>
<input name="submit" ...>
...
</form>
Because browser tradition is to add to the form element's object (as properties) inputs' names, the "submit" property from the input masks the form's inherent "submit" property or method. You can correct this by renaming, even temporarily, the input element (assuming there's just the one):
form_object.elements['submit'].name = 'notsubmit';
form_object.submit();
If there are more than one -- eg, a series of radio buttons named "submit" for some reason -- then .elements['submit'] should be an element collection, which is like an array, which you can loop over to do the same thing.
You know you can set a target attribute for the form?
<form target="_blank" method="post">
<select onchange="load()">
...
</select>
</form>
<script>
load() {
document.forms[0].action = this.value;
document.forms[0].submit();
}
</script>
Forgive the probably bad Javascript. I tend to do more jQuery these days so I'm rusty on vanilla Javascript. But you get the general idea.
While I'm not familiar with jQuery, you should be able to do something like this (Prototype-style):
$('select-field').observe('change',function(event){
window.open(this.options[this.selectedIndex].value,'_blank');
this.form.submit();
}
Though I have had a few odd issues with submitting forms with Javascript before, so if that doesn't work you could try calling click() or the equivalent of fireEvent('click') on your form's submit button, like so:
$('submit-button').fireEvent('click');
