I've got a problem regarding my contact form page. I did callback after clicking the submit button. I tried not to fill name textbox but form still submits.
My code:
function sendFeedback() {
alert("Thank you for the feedback :)");
}
<form>
<p class="font3">Name:</p>
<input name="name" type="text" maxlength="50" size="30" required/>
<br />
<p class="font3">Email:</p>
<input name="email" type="email" placeholder="" required/>
<br />
<p class="font3">Subject:</p>
<input name="subject" type="text" required/>
<br />
<p class="font3">Message:</p>
<textarea name="comment" row="80" cols="30" required></textarea>
<br>
<br>
<input type="submit" value="Submit" onclick="sendFeedback()">
<input type="reset" value="Reset">
</form>
You should change <form> to <form onsubmit="test()",where test() would go something like this:
test(e){
e.preventDefault();
/* do some validations here */
document.querySelector("form").submit();
}
Hope it helps
The form submitting and your alert triggering are two completely different things. The required attributes you have on the inputs are working correctly. If you leave any of the required inputs blank, the form will not submit to the server, instead you'll trigger standard error messaging in whatever browser you're using (usually a red outline and a popover).
The bit of JavaScript you have (i.e. your alert) will trigger regardless of whether the form submits successfully or not since it's executed BEFORE the submit goes through. You need to either do something like e.preventDefault() or return false at the end of your function, but that will prevent the form from being submitted altogether.
As #dvenkatsagar said, your best option is to change your onclick to onsubmit.

JS Fiddle FROM EXAMPLE
I want to send an email using a webservice on the onclick event of a button, but noticed that the event is triggered regardless the form validation, so the question is, is there a way to trigger the onclick event only if the form is valid without using javascript? perhaps HTML5 has something new to offer
I think the problem is that you are attaching an action to the button click not the form submit. So, two things are happening here:
You are atually using javascript in onclick="alert('whatever')"
You are binding this script to the button click not the form submit
Your validation is working fine for the submit action. Consider use the action parameter in form not the onclick param in the input button.
EDIT:
To be more precise the <input type="submit" value="Submit"> default click action is submitting the form.
Hope it helps!
When I need some extra validation I change submit input to an element 'a' with an 'id' that I can check on a jquery click function. So I validate and I fire a submit manually. Example: $('#formId').submit ().
The best possible way is to bind the action to onsubmit event of the form rather than onclick event of button as user onepopcorn mentioned. It can be done by using
<form action="" method="post" onsubmit=alert('whatever')>
instead of using onclick for the submit button.
I have a very simple form:
<form>
<fieldset>
<input id="in1" type="text" data-validate="required">
</fieldset>
<fieldset>
<input id="in2" type="text" data-validate="required">
</fieldset>
<input id="btn" type="button" value="Insert your datas" onclick="insert()">
</form>
If third input (id:"btn") had type="submit", notify/verify would work well.
I don't need to submit this form (because I have to launch an insert() function on button onclick),
so I deleted the submit type of my button and unfortunately no notifications appear on my page now.
I may add an handler (like this: $(".elem-demo").notify("Hello Box")) as notify docs suggest, but that is a custom notification, good, but I want to take advantage of verify.js data-validate..no extra-code required for a simple validation like "required" or "number".
How can I fix that?
I wish I was clear of my issue and thanks to answer me.
You can keep the button type submit and can override the default form submission behavior on submit button click via event.preventDefault()
<form id="my-form" onSubmit="myFunction(event)">
<fieldset>
<input id="in1" type="text" data-validate="required">
</fieldset>
<fieldset>
<input id="in2" type="text" data-validate="required">
</fieldset>
<input id="btn" type="submit" value="Insert your datas" onclick="insert()">
</form>
This your function which will be called on form submission.Access the form via its id and call validate to check form for errors.
Calling validate will trigger validation on every element in the form. It accepts a callback function callback(success) which will be called after validation.
function myFunction(e){
e.preventDefault();
$("#my-form").validate(callbackFunction);
// call your other function
}
I need to have a form with a button which on submit, check for required field but does not refresh the page.
<form>
<fieldset>
<input type="text" id="firstname" placeholder="First Name" required/>
<input type="submit" value="Send"/>
</fieldset>
</form>
If I disable on submit for form, it wont check for required fields anymore. I need all the functionality of onSubmit but without refreshing the page.
I will appreciate any help.
I'm unsure why you are getting an error. The code provided should work. Try adding an action and a method just in case as follows:
<form action="" method="POST" onsubmit="myFunction()">
<fieldset>
<input type="text" id="firstname" placeholder="First Name" required>
<input type="submit" value="submit">
</fieldset>
</form>
You can then add a function called myFunction down below as follows:
<script>
function myFunction() {
alert("Form was submitted");
}
</script>
For example, I have this form:
<form action="destination.jsp" method="POST">
<input type="text" name="Productqty1"/>
<input type="text" name="Productqty2"/>
<input type="text" name="Productqty3"/>
<input type="submit" name="RecalculatePrice" value="Recalculate Price"/>
<input type="text" name="ZipCode"/>
<input type="submit" name="RecalculateShipping" value="Recalculate Shipping"/>
<input type="text" name="Offercode"/>
<input type="submit" name="RecalculateDisc" value="Recalculate Discount"/>
<input type="submit" name="CheckOut"/>
</form>
I need that if the user press enter on Productqty1, Productqty2, or Productqty3, then the default action is suppressed, and button RecalculatePrice is clicked instead.
And the same goes with if user press enter on ZipCode, the RecalculateShipping button gets clicked instead. The same with Offercode input and RecalculateOffercode button.
But if the user press on CheckOut button, the whole form must be still submitted. That's why they're on the same form, multiple submit button on the same form.
I also need to suppress the default action of enter key, because IE8 did not sent button submit value along with the form submit, so let's disable it altogether to avoid confusion.
How can I find a unified solution for this? It's okay if it has to be made in multiple javascript function, just as long as I can understand the solution pattern, because form with multiple submit button and user can press enter on any input field is confusing me. JQuery solutions are welcomed. Thanks.
EDIT: sorry for the poor choice of words that lead to confusion. What I mean with suppress default action is that when you press enter, the form get submitted, using any (random?) button submit. That is the default behavior I want to suppress.
I have added classes and id for each submit button(added id) and text box(added class).
Try this
<form action="destination.jsp" method="POST">
<input type="text" name="Productqty1" class="class1"/>
<input type="text" name="Productqty2" class="class1"/>
<input type="text" name="Productqty3" class="class1"/>
<input type="submit" name="RecalculatePrice" value="Recalculate Price" id="class1"/>
<input type="text" name="ZipCode" class="class2"/>
<input type="submit" name="RecalculateShipping" value="Recalculate Shipping" id="class2"/>
<br><br>
<input type="text" name="Offercode" class="class3"/>
<input type="submit" name="RecalculateDisc" value="Recalculate Discount" id="class3"/>
<input type="submit" name="CheckOut"/>
</form>
Script
$(document).ready(function () {
$(".class1").keypress(function (event) {
if (event.which == 13) {
event.preventDefault();
$('#class1').click();
}
});
$(".class2").keypress(function (event) {
if (event.which == 13) {
event.preventDefault();
$('#class2').click();
}
});
$(".class3").keypress(function (event) {
if (event.which == 13) {
event.preventDefault();
$('#class3').click();
}
});
});
Fiddle Demo
I would argue that CheckOut is your special scenario here. While you could certainly catch the enter key and invoke different actions, there are primarily two reasons why I don't find that to be the optimal solution here:
Your IE8 concern seems to negate the entire prior discussion, and in my mind, this should advise you to look in another direction. Don't do a special solution for IE8, do something that all supported browsers can understand.
There is no field for which CheckOut should be the default action on enter.
I suggest that you make different forms, and use different actions, rather than checking which button was clicked by inspecting the name parameter of the button.
On click of the CheckOut-button, which should never be triggered by an enter key, you should submit all forms. You can serialize their combined values and post them like so:
$('#product-form, #zip-form, #offer-form').serialize();
You can use jquery/javascript function to change the form.action before submitting the page.
Submit type should submit the form to default form action, which has been added on form declaration.
<form action="destination.jsp" method="POST">
<input type="text" name="Productqty1"/>
<input type="text" name="Productqty2"/>
<input type="text" name="Productqty3"/>
<input type="button" name="RecalculatePrice" value="Recalculate Price"/ onClick="callDefault();">
<input type="text" name="ZipCode"/>
<input type="button" name="RecalculateShipping" value="Recalculate Shipping"/ onClick="callRecalculateShipping();">
<input type="text" name="Offercode"/>
<input type="button" name="RecalculateDisc" value="Recalculate Discount"/ onClick="callRecalculateDisc();">
<input type="button" name="CheckOut"/ onClick="callCheckout();">
</form>
<javascript>
function callCheckout(){
form.action="<some value>";
form.submit();
}
...so on with other functions...
</javascript>
Change input types to button .
I've searched for a solution to this issue all over the web. After no success, here I am. I have a form that where I have 3 fields that should contain data. Field 1 is the Zip Code, Field 2 and 3 are City and State respectively.
The JS function getCityByZipHome and getStateByZipHome dynamically return the city and state and insert the values into the the city2 and state2 input fields.
For whatever reason, when I submit the form via mouse-click.. I see the data via $_POST. If the users presses ENTER, the data is never captured and I never see that data from the hidden fields.
Any idea what's wrong here? Note, I've tried almost all the event handlers onblur, onclick, onchange..etc.
<form method="post" name="something" action="xxSome.php">
<div class="s_row">
<label for="zippy">Enter Zip Code</label>
<input id="zipcode_home" tabindex="2" type="text" onkeypress="javascript:getCityByZipHome(document.getElementById('zipcode_home').value, this.form.elements['city3']);javascript:getStateByZipHome(document.getElementById('zipcode_home').value, this.form.elements['state3']);" name="zipcode_home"/>
<input id="state3" name="state3"type="hidden"/>
<input id="city3" name="city3" type="hidden"/>
<input type="submit" value="Start Now!"/>
</div>
</form>
I've tried adding onsubmit # the form level as such:
<form method="post" name="something" action="xxSome.php" onsubmit="javascript:getCityByZipHome(document.getElementById('zipcode_home').value, this.form.elements['city3']);javascript:getStateByZipHome(document.getElementById('zipcode_home').value, this.form.elements['state3']);">
<div class="s_row">
<label for="zippy">Enter Zip Code</label>
<input id="zipcode_home" tabindex="2" type="text" name="zipcode_home"/>
<input id="state3" name="state3"type="hidden"/>
<input id="city3" name="city3" type="hidden"/>
<input type="submit" value="Start Now!"/>
</div>
</form>
And I've tried onblur without any luck # the input level as such:
<form method="post" name="something" action="xxSome.php">
<div class="s_row">
<label for="zippy">Enter Zip Code</label>
<input id="zipcode_home" tabindex="2" type="text" onblur="javascript:getCityByZipHome(document.getElementById('zipcode_home').value, this.form.elements['city3']);javascript:getStateByZipHome(document.getElementById('zipcode_home').value, this.form.elements['state3']);" name="zipcode_home"/>
<input id="state3" name="state3"type="hidden"/>
<input id="city3" name="city3" type="hidden"/>
<input type="submit" value="Start Now!"/>
</div>
</form>
After all the messing around, I actually never solved the issue; rather, I disabled the ENTER key as a submit method.
I have some pretty serious time constraints, but I'm sure this will come up later and I will definitely come back to this issue.
You should do the getcitybyzip and getstatebyzip in the form onSubmit.
Change the type of the submit to button and then add on onClick method to it. ie instead of make it but you need an id on the form to do that. I would be interested though in finding the cause of what is going wrong. Did you try firebug?
