I can't tell what I have done wrong here.
This part seems to be working, or at least it fires, because a breakpoint set with the debugger breaks in the code.
<script>
jQuery("#contactForm").validationEngine();
</script>
But it doesn't seem to be hooked up to the form fields and doesn't attempt to validate, or validates improperly, when used like this:
<form class = "contactform" id = "contactForm">
<fieldset>
<div class="contactform-email contactform-field">
<label class="contactform-label" for="contactform-email">Email Address:
<br>
</label>
<input class="validate[required,custom[email]] contactform-input" type="email" id="contactform-email" name="email" />
</div>
<input class="contactform-button" type="submit" name="submit" value="Send"/>
</fieldset>
</form>
Is there something I've mis-configured?

OK, I finally solved it.
The thing is that this code is running within the Meteor JavaScript framework and it expects code such as
jQuery("#contactForm").validationEngine();
To be in a Template.myTemplate.rendered function to execute properly and at the right time.
Still learning...

I'm very new to JS. But basically, I'm creating a form. Using JavaScript, how do I take a form so that you must fill in form data?
Thanks!
HTML:
<form>
<p>First Name:</p>
<input type="text" name="firstname" class="form">
<p>Last Name:</p>
<input type="text" name="lastname" class="form">
<p>Email:</p>
<input type="text" name="email" class="form">
<p>Questions / Concerns:</p>
<textarea name="concerns" rows="5" cols="30"></textarea>
<br>
<input type="submit" name="submit" value="Submit">
<input type="reset" name="reset" value="Reset">
</form>
There are multiple ways of solving this particular problem.
The easiest way would be to use the required tag in elements:
<input type="text" name="firstname" class="form" required>
Edit: This may not work in very old browsers.But I don't believe you need to worry about that now.
Use required tag in all of your input elements which you need filling compulsorily.
Once you have your basic problem solved, look at using javascript functions for validation. Ref: https://www.w3schools.com/js/js_validation.asp
Once you know this, you can safely progress to reading on how validation is done on large projects- https://validatejs.org/
use document.getElementByTagName to get the input tag
Use addEventListner with first parameter as blur to detect input leave
Use this.value within if statement to check if empty
Alert something
var element=document.getElementByTagName(input);
element.addEventListner("blur",myFunction);
function myFunction(){
if(this.value==''){
alert ("write something");
}
}
I am trying to validate the fields using CFINPUT and then calls a popup window function to do more stuff BEFORE submitting the form but it's not working. The onclick function seems to take precedent over the CFINPUT validation. As soon as I click on the Submit button it's calling the popup window function first without validating the fields. I need it to:
first validate the fields
call the popup function
then submit the form after the popup closes itself
(p.s. I see other similar case on here but there is no answer given)
The code looks like this:
<cfform action="register.cfm" method="post">
<cfinput type="text" name="username" size="50" maxlength="100" required="yes" autofocus="on" validate="noblanks">
<cfinput type="text" name="address" size="50" maxlength="100" required="yes" validate="noblanks">
....
<input type="submit" value=" Send " onclick="popup()">
....
Please help. Thank you.
This is an old blog posting so not sure how accurate things are today but it shows how you can run the CFFORM validation via the _CF_checkTaskForm() function. So it seems like if you change the submitting of the form to a button via <input type="button" value="Send" onclick="popup(this.form)" /> then change the popup function to first validate the form via the _CF_checkTaskForm() and if that passes to proceed with the other JS you are doing.
http://www.neiland.net/blog/article/triggering-cfform-validation-when-using-ajax/
To expand on that, I just looked at a CF8 and CF11 installations and looks like the function in those is _CF_checkCFForm_1 if using that version of CF then something like this should get you in the correct direction:
<script>
popup = function(formreference) {
var check = _CF_checkCFForm_1(formreference);
if (!check) {
//if the rules failed then do not submit the form
return false;
} else {
// Do the popup
}
}
</script>
<cfform action="register.cfm" method="post">
<cfinput type="text" name="username" size="50" maxlength="100" required="yes" autofocus="on" validate="noblanks">
<cfinput type="text" name="address" size="50" maxlength="100" required="yes" validate="noblanks">
<input type="button" value=" Send " onclick="popup(this.form)" />
</cfform>
The cfinput validation you're attempting to do is the client-side equivalent to
<cfif len(trim(string)) gt 0>
(Edit: That is not to imply that you should depend wholly on client side validation. Client-side validation is more of a feature to help your visitors. Server side validation is still important.)
Which I have to say is really weak validation. Anything consisting of at least 1 non-whitespace character will pass the test. People will be able to have usernames like "!" which isn't fanstastic, but that's just some information.
On the jQuery Validate link you provided, they show an example form (along with a link of the same form in action)
<form class="cmxform" id="commentForm" method="get" action="">
<fieldset>
<legend>Please provide your name, email address (won't be published) and a comment</legend>
<p>
<label for="cname">Name (required, at least 2 characters)</label>
<input id="cname" name="name" minlength="2" type="text" required>
</p>
<p>
<label for="cemail">E-Mail (required)</label>
<input id="cemail" type="email" name="email" required>
</p>
<p>
<label for="curl">URL (optional)</label>
<input id="curl" type="url" name="url">
</p>
<p>
<label for="ccomment">Your comment (required)</label>
<textarea id="ccomment" name="comment" required></textarea>
</p>
<p>
<input class="submit" type="submit" value="Submit">
</p>
</fieldset>
</form>
<script>
$("#commentForm").validate();
</script>
This very basic example shows how simple Validate can be to install, and a simple format of
<input name="ele" type="text" required>
is exactly the same level of validation you're attempting. So, to begin with, you can almost copy and paste the code. (Aside from from the different requirements you can make, setting minlength requires a certain number of characters and requires that at least one not be whitespace).
jQuery Validate can get quite extensive but is very easy to basically install and once you become familiar, make custom classes as needed
As a final note, don't disregard the disdain for CFForm elements. It may seem like others are disregarding your question, but that's not the case.
To be honest, they began to be introduced at a different time in the life of the internet, but have always been kind of finicky to work with. Expansion to them, in the opinions of many, have not been done well and have frequently exasperated the flaws.
It's super attractive to be able to say <cfinput...required> but the tags become a nuisance and you don't easily have the fine control over them that you might desire. They're a crutch, and a rusty crutch at that.
You might check out CFUI The Right Way # Github or this hosted version for some great insight and examples.
I hope someone can assist with this. I dont have access to the website backend, so I cant change the js script uploaded there. What I am trying to achieve is make a simple form to submit an issue report and then display a "Thank you" popup and redirect back to main page of the account on our page.
So I can make a form no problem. I copied one of the functioning forms by going to Edit link and clicking on Show Source in Page Body. But I can't stop the default behavior of it going to another page after Submit button is pressed. I suspect it is in js script on the back end. I'll copy code below.

I tried searching and suggestions here didnt seem to work:
How to redirect user to another page after Ajax form submission
How to redirect user to another page after Ajax form submission?
http://learn.jquery.com/about-jquery/how-jquery-works/
The first thing you have to look at is action="/Modules/SendForm" - this is what does the redirection. If you don't want to redirect, set this to the name of the page you have the form. Obviously there is a whole lot more to forms and redirection (and some other js code might influence this too, nonetheless we don't see what the function setupAjaxForm is supposed to do here), but this is really the first thing to check / get right.
EDIT: I think I understand it more now: basically if you don't have access to the /Modules/SendForm page (where most probably, among others, like form validation, the redirection also happens, then you can't do much to change the redirection.
I created an update form wherein you can update each field individually. One of my fields is for password reset. I've been trying to use the jquery function validate to make validations for this field. I've tested in jsfiddle and the code works perfectly. Strangely however, when I run my actual php script, the validation messages don't appear to work. My the code in jsfiddle, is pretty much the same as the one in my php script (Except for the value of the password field. Here's the snippet from my script:
<form method="POST" id="update_password">
<div>
<label>Password:</label>
<input type="password" id="user_password" name="user_password" value="if(isset($_POST['user_password'])){ echo $_POST['user_password']; } else { echo $session_username; }" />
<input type="submit" value="Submit" id="submit_password"/>
</div>
</form>
So my question is pretty much simple, how come this code snippet works on jsfiddle but not on my actual php script when I run it in localhost? Can someone please point me to the right direction?
I think you forgot to put the PHP opening and closing tags.
<form method="POST" id="update_password">
<div>
<label>Password:</label>
<input type="password" id="user_password" name="user_password" value="<?php if(isset($_POST['user_password'])){ echo $_POST['user_password']; } else { echo $session_username; }?>" />
<input type="submit" value="Submit" id="submit_password"/>
</div>
</form>
Also I'm not sure why you would want to print the "session_username" in the password field...
I would like to fill out and a submit a form explicitly with JavaScript. First, I thought I had to use window.open but it's certainly wrong because if it gets loaded, the left of my scripts written for example in a html file would be ignored.
Do I have to create a .js file and fire that one?
uhhhh...not exactly sure how this relates to injections...you can do this with jQuery in a handful of lines of code.
say you have the following form:
<form id="theForm" name="testForm" action="whatever.php" method="get">
<input type="text" name="cow" />
<input type="text" name="sheep" />
<input type="text" name="pig" />
<input type="submit" value="Submit" />
</form>
If you have jQuery loaded, all you need to do is this:
function submitForm(){
var cowVal="Cows go moooo!";
var sheepVal="Sheep go baaaaaaah!";
var pigVal="pigs go sooooeeeeeeeh!";
$("#theForm input").eq(0).val(cowVal).next().val(sheepVal).next().val(pigVal).parent().submit();
}
Hope that helps!
