I am trying to remove a required attribute from an input on the fly. The general idea is I have a field that is set to required, this field has custom validation with the pattern attribute. When the user clicks a button I am attempting to remove the required field.
I have put together a fiddle here:
https://jsfiddle.net/paulmatos/t1p1wub3/
HTML:
<form>
<input type="text" oninvalid='this.setCustomValidity("Enter a number in the Specified Range");' oninput="try{setCustomValidity('')}catch(e){}" pattern="[0-9]" required="required" name="password" id="password" />
<input type="text" required="required" name="temp" />
<input type="submit" class="btn btn-primary form-control" value="Submit" />
<div class="btn btn-default removeReq">Remove Required</div>
</form>
Jquery:
$('.removeReq').click(function() {
$('#password').removeAttr('required');
});
The issue I am experiencing has to do with the order of submission.
If you click remove required, and then submit the form you will see that it works as intended.
However, if you do those steps in reverse order, click submit first, then remove and try and submit again, you will notice I am still getting the validation error on the first input.
Is there anyway to get around this with this intended functionality, I am trying to get this to work just with the html5 validation.
I did have a look at the fiddle and the only way I could get the behaviour you wanted was by literally detaching, cloning and reinserting the field. Works tho.
$('.removeReq').click(function() {
var password = $('#password').removeAttr('required oninvalid oninput pattern').detach().clone();
$('form').prepend(password);
});

Think you are getting this due to the code in the oninvalid handler. Try this.
$('.removeReq').click(function() {
$('#password').removeAttr('required oninvalid');
});
You can try this instead of removeAtt():
$('.removeReq').click(function() {
$('#password').prop('required', false);
});
I have a simple form
<form action="#" method="GET" class="parsleyVal">
<div class="input-group input-group-lg">
<input type="email" name="email" class="form-control input-email"
placeholder="Enter your email"
data-parsley-required-message="Please enter your email address"
data-parsley-required title="Please enter your email address"
auto-complete="off" data-parsley-trigger="submit" />
<span class="input-group-btn">
<button class="btn btn-orange" type="submit" data-parsley-trigger="click touch">
Sign up
</button>
</span>
</div>
</form>
Validation starts when the sign-up button is clicked.
However, if there is no email specified, an error is shown:
enter your email.
When users start typing their email address, parsley.js does the automatic validation and shows that email must be valid.
I'd like parsley.js to re-validate the email field when submit button is clicked again but not on the fly.
I have tried xCodexInlinexPlacexHolderx on the input field - does not help.
Looks like I finally figured out what I wanted.
Might be not ideal way to do it, if anyone could recommend something else.
$('.parsleyVal input[type=email]').on('keyup keydown', function () {
$('.filled').removeClass('filled');
$('.parsleyVal').parsley().destroy();
})
Script removes class to hide error message and destroy parsley validation, which will be triggered again on sign-up button click.
You can control what triggers the validation with two different settings:
data-parsley-trigger
Setting for what triggers the validation the first time. The default is null which basly means on submit
data-parsley-trigger-after-failure
Setting for what triggers a revalidation after the first failure. The default is input which means that the field will be revalidated after each change on the field.
The setting you need is: data-parsley-trigger-after-failure
Example:
<input type="email" id="profile-email"
data-parsley-required="true"
data-parsley-trigger-after-failure="submit"/>
I have a very simple form as follows. I want to make it so that the Submit button is disabled, and only enabled after the user has successfully completed the ReCaptcha.
I'm assuming I'm going to need some Javascript / jQuery to do this.
Google's documentation on ReCaptcha 2.0 seems really sparse and dense (to me, anyway). I'd appreciate some pointers:
<form action="something.php" method="post">
Name: <input type="text" size="40" name="name"><br><br>
<div class="g-recaptcha" data-sitekey="############-#####"></div>
<input type="submit" value="Submit" >
</form>
i did the same thing on my test site. however, i used a button instead of submit, so here:
you must add the property data-callback="enableBtn" data-callback property executes the function specified after accomplishment of recaptcha.
<div class="g-recaptcha" data-sitekey="############-#####" data-callback="enableBtn"></div>
and set the id of the button to whatever id you want to and set it to disabled:
<input type="button" value="Submit" id="button1" disabled="disabled">
then on javascript make a function to enable the button
function enableBtn(){
document.getElementById("button1").disabled = false;
}
I have applied ParsleyJS validation to a form that has multiple submit buttons that perform various tasks. I only want the validation to occur for one of the submit buttons, is this possible? if so, how?
For a pared down example:
<form name="aspnetForm" method="post" action="page.aspx" id="aspnetForm" data-validate="parsley">
<input type="text" id="text_for_example" data-required="true"/>
<input type="text" id="text_for_example2" data-required="true"/>
<input type="text" id="text_for_example3" />
<input type="submit" id="ClearsTheTextBoxes"/>
<input type="submit" id="SavesData" />
</form>
Ideally I want it to validate only on the "SavesData" submit, not on the "ClearsTheTextsBoxes". is this possible using ParsleyJS?
Thanks!
Note:
I cannot change the type any of the submit buttons to function differently; please do not suggest this. The "ClearsTheTextsBoxes" must remain a submit button.
to do so, you'll have to remove data-validate="parsley" from your form tag, and add a custom js function on click on the desired button. Then in this function, simply to a $('aspenetForm').parsley('validate');

I'm working on a simple javascript login for a site, and have come up with this:
<form id="loginwindow">
<strong>Login to view!</strong>
<p><strong>User ID:</strong>
<input type="text" name="text2">
</p>
<p><strong>Password:</strong>
<input type="password" name="text1"><br>
<input type="button" value="Check In" name="Submit" onclick=javascript:validate(text2.value,"username",text1.value,"password") />
</p>
</form>
<script language = "javascript">
function validate(text1,text2,text3,text4)
{
if (text1==text2 && text3==text4)
load('album.html');
else
{
load('failure.html');
}
}
function load(url)
{
location.href=url;
}
</script>
...which works except for one thing: hitting enter to submit the form doesn't do anything. I have a feeling it's cause I've used "onclick" but I'm not sure what to use instead. Thoughts?
Okay yeah so I'm well aware of how flimsy this is security-wise. It's not for anything particularly top secret, so it's not a huge issue, but if you guys could elaborate on your thoughts with code, I'd love to see your ideas. the code i listed is literally all I'm working with at this point, so I can start from scratch if need be.
There are several topics being discussed at once here. Let's try to clarify.
1. Your Immediate Concern:
(Why won't the input button work when ENTER is pressed?)
Use the submit button type.
<input type="submit".../>
..instead of
<input type="button".../>
Your problem doesn't really have anything to do with having used an onclick attribute. Instead, you're not getting the behavior you want because you've used the button input type, which simply doesn't behave the same way that submit buttons do.
In HTML and XHTML, there are default behaviors for certain elements. Input buttons on forms are often of type "submit". In most browsers, "submit" buttons fire by default when ENTER is pressed from a focused element in the same form element. The "button" input type does not. If you'd like to take advantage of that default behavior, you can change your input type to "submit".
For example:
<form action="/post.php" method="post">
<!--
...
-->
<input type="submit" value="go"/>
</form>
2. Security concerns:
#Ady mentioned a security concern. There are a whole bucket of security concerns associated with doing a login in javascript. These are probably outside of the domain of this question, especially since you've indicated that you aren't particularly worried about it, and the fact that your login method was actually just setting the location.href to a new html page (indicating that you probably don't have any real security mechanism in place).
Instead of drudging that up, here are links to related topics on SO, if anyone is interested in those questions directly.
Is there some way I can do a user validation client-side?
Encrypting Ajax calls for authentication in jQuery
3. Other Issues:
Here's a quick cleanup of your code, which just follows some best practices. It doesn't address the security concern that folks have mentioned. Instead, I'm including it simply to illustrate some healthy habits. If you have specific questions about why I've written something a certain way, feel free to ask. Also, browse the stack for related topics (as your question may have already been discussed here).
The main thing to notice is the removal of the event attributes (onclick="", onsubmit="", or onkeypress="") from the HTML. Those belong in javascript, and it's considered a best practice to keep the javascript events out of the markup.
<form action="#" method="post" id="loginwindow">
<h3>Login to view!</h3>
<label>User ID: <input type="text" id="userid"></label>
<label>Password: <input type="password" id="pass"></label>
<input type="submit" value="Check In" />
</form>
<script type="text/javascript">
window.onload = function () {
var loginForm = document.getElementById('loginwindow');
if ( loginwindow ) {
loginwindow.onsubmit = function () {
var userid = document.getElementById('userid');
var pass = document.getElementById('pass');
// Make sure javascript found the nodes:
if (!userid || !pass ) {
return false;
}
// Actually check values, however you'd like this to be done:
if (pass.value !== "secret") {
location.href = 'failure.html';
}
location.href = 'album.html';
return false;
};
}
};
</script>
Put the script directly in your html document. Change the onclick value with the function you want to use. The script in the html will tell the form to submit when the user hits enter or press the submit button.
<form id="Form-v2" action="#">
<input type="text" name="search_field" placeholder="Enter a movie" value=""
id="search_field" title="Enter a movie here" class="blink search-field" />
<input type="submit" onclick="" value="GO!" class="search-button" />
</form>
<script>
//submit the form
$( "#Form-v2" ).submit(function( event ) {
event.preventDefault();
});
</script>
Instead of <input type="button">, use <input type="submit">. You can put your validation code in your form onsubmit handler:
<form id="loginwindow" onsubmit="validate(...)">
it's because it's not a form submitting, so there's no event to be triggered when the user presses enter. An alternative to the above form submit options would be to add an event listener for the input form to detect if the user pressed enter.
<input type="password" name="text1" onkeypress="detectKey(event)">
Maybe you can try this:
<form id="loginwindow" onsubmit='validate(text2.value,"username",text1.value,"password")'>
<strong>Login to view!</strong>
<p><strong>User ID:</strong>
<input type="text" name="text2">
</p>
<p><strong>Password:</strong>
<input type="password" name="text1"><br>
<input type="submit" value="Check In"/>
</p>
</form>
As others have pointed out, there are other problems with your solution. But this should answer your question.
Surely this is too unsecure as everyone can crack it in a second ...
-- only pseudo-secure way to do js-logins are the like:
<form action="http://www.mySite.com/" method="post" onsubmit="this.action+=this.theName.value+this.thePassword.value;">
Name: <input type="text" name="theName"><br>
Password: <input type="password" name="thePassword"><br>
<input type="submit" value="Login now">
</form>
My Thought = Massive security hole. Anyone can view the username and password.
More relevant to your question: - You have two events happening.
User clicks button.
User presses enter.
The enter key submits the form, but does not click the button.
By placing your code in the onsubmit method of the form the code will run when the form is submitted. By changing the input type of the button to submit, the button will submit the form in the same way that the enter button does.
Your code will then run for both events.
