I use bootstrap in my html form as below. It has a user name input field with a simple validation rule which is length must between 1 and 16 characters. I wonder how I can put more validation rules on this field. For example, I want to check the username must not start with a number and doesn't include special characters like * # # etc. I am fine if it requires some jquery code. But I don't know how to inject the validation logic and make it works wit the with-errors div.
<div class="form-group">
<label for="user-username-input">User Name</label>
<input type="text" class="form-control" id="user-username-input" placeholder="User Name" maxlength="16" data-minlength="1" data-error="Required" required>
<div class="help-block with-errors"></div>
</div>
Use html5 input pattern attribute.
<form>
<div class="form-group">
<label for="user-username-input">User Name</label>
<input type="text" class="form-control"
id="user-username-input" placeholder="User Name"
pattern="[a-zA-Z]+[a-zA-Z0-9]{1,16}"
title="Username should be alphanumeric of length upto 16 characters and first character can not be number."
required>
<div class="help-block with-errors"></div>
<input type="submit" value="submit">
</div>
</form>

is there a way to validate minlength on my field in IE11? seems like is being ignored, I am using bootstrap 4.5 to validate my form also.
<input class="form-control" id="portVal" required="" type="text" pattern="[0-9]*" data-dpmaxz-eid="5" minlength="6">
However, seems like email pattern is validating email correctly, how can I update [0-9]* to configure a minimum number?
<input class="form-control" id="sEmail" required="" type="text" pattern="[a-z0-9._%+-]+#[a-z0-9.-]+\.[a-z]{2,4}$" data-dpmaxz-eid="4" data-nl-label="Email" data-nl-bindto="xpath" data-nl-ismandatory="true" data-nl-xpath="#email">
IE doesn't support the minlength attribute. You'll have to use the regex .{6,}, which matches 6 or more characters:
<form>
<input class="form-control" id="portVal" type="text" pattern=".{6,}" data-dpmaxz-eid="5" required>
<button>Submit</button>
</form>
I need someone to please tell me how to remove this auto-suggested text below the input field. I have tried autocomplete="off" , autocomplete="false". I've also placed <form autocomplete="off"></form> in form tag.
Anyone with a solution please help.
<div class="col-md-6">
<div class="form-group">
<span class="label">Enter Postal Code</span>
<input type="text" class="form-control" id="search_input" autocomplete="off" placeholder="Type postal code ..." required>
</div>
</div>
Here you can see which browsers support the autofill attribute CaniUse. Here is a simple work around from this source: Turning off form-autocompletion.
You can work around with autofill="new-password"
"If you are defining a user management page where a user can specify a new password for another person, and therefore you want to prevent autofilling of password fields, you can use autocomplete="new-password"."
<form method="post" action="/form">
<div>
<label for="cc">Enter Postal Code:</label>
<input type="text" id="cc" name="cc" autocomplete="new-password">
</div>
</form>
Lastly, instead of pairing a <span> with the input element, it is common practice to use the <label> element. Please read more here label
Apply autocomplete="off" to your form not the input box.
I am making a simple template-driven form with 'Email Validation' in it (Not by Reactive Forms). So, required, minlength, maxlength are working fine. But, when I try email to be valid, its failing. Can someone help me out?
abc.component.html
<form #customForm="ngForm" (ngSubmit)="alpha(customForm)">
<input type="text" name="firstName" ngModel #firstName ="ngModel" required minlength="3" maxlength="10"><br/>
<div *ngIf="firstName.touched">
<p *ngIf="firstName.errors?.required">First Name is Required!!!</p>
<p *ngIf="firstName.errors?.minlength">First Name minimum 3 characters are required!!!</p>
<p *ngIf="firstName.errors?.maxlength">First Name max length is 10!!!</p>
</div>
<input type="email" name="email" ngModel #email="ngModel" required><br/>
<div *ngIf="email.touched">
<p *ngIf="email.errors?.required">Email is a required field!</p>
<p *ngIf="email.errors?.email">This is not a valid Email!!!</p>
</div>
<button type="submit" [disabled]="customForm.invalid">Submit</button>
</form>
Note: Though required validation of email is taking place, but as the
pattern or data entered is not correct, the 2nd validation in email
validation div must give error.
Result: (Email valid and its pattern not automatically giving error)
You could add an email attribute to your Email Input. But then that would not in-validate it for something of the pattern xxx#xxx which I think would not be a valid email in your case.
I suggest you use pattern="[a-z0-9._%+-]+#[a-z0-9.-]+\.[a-z]{2,4}$" instead. Then, where you're showing the error message, you should check for email.errors?.pattern instead.
Give this a try:
<input
type="email"
name="email"
ngModel
#email="ngModel"
pattern="[a-z0-9._%+-]+#[a-z0-9.-]+\.[a-z]{2,4}$"
required>
<br/>
<div *ngIf="email.touched">
<p *ngIf="email.errors?.required">Email is a required field!</p>
<p *ngIf="email.errors?.pattern">This is not a valid Email!!!</p>
</div>
Try both the approaches on this Sample StackBlitz and use the one that suits you better.
Replace this line
<input type="email" name="email" ngModel #email="ngModel" required>
with
<input type="email" name="email" ngModel #email="ngModel" required email>// add email attribute
use "pattern = regrex" in input tag and use validation email?.errors?.pattern
This is my first time using this plugin. I am using jQuery v-1.10. I am also using the migrate plugin. I have added the js file. I have added all of these using prepros. But still the plugin is not working.
No error is also showing in the console; only a warning is showing saying:
event.returnValue is deprecated. Please use the standard event.preventDefault() instead.
My form and the JS code is given below.
<form id="login-form" method="post" action="#" novalidate>
<label for="login-email" class="control-label">Email : </label>
<input id="login-email" class="form-control" name="email" type="email" placeholder="Email..." required><br>
<label for="login-password" class="control-label">Password : </label>
<input id="login-password" class="form-control" name="password" type="password" placeholder="Password..." required><br>
<input class="btn btn-default" name="submit" type="submit" value="Submit">
</form>
$("#login-form input").not("[type=submit]").jqBootstrapValidation();
You must use proper controls in your markup for this to work.
Ex.
<form ...>
<div class="control-group">
<label ...>Email</label>
<div class="controls">
<input ... />
<p class="help-block"></p>
</div>
</div>
</form>
And personally I believe the better way of handling the javascript is to create a "validated" class because not all fields will require validation. But I suppose this really depends on your form elements: you may indeed require the entire form to be validated but in most of the forms I've worked with, only certain elements require validation and therefor creating a class to call in your javascript is better so that jqBootstrapValidation.js isn't scanning the entire form.
Ex.
/* assigned by class */
$(function(){$(".validated").jqBootstrapValidation();});
/* assigned by element */
$(function(){$("input,select,textarea").not("[type=submit]").jqBootstrapValidation();});
Then simply add your "validated" class to anything you need validated:
<input type="email" class="form-control validated" name="email" id="email" placeholder="Email Address" required />
Hope this helps!

Basically I need to add more validation to not allow less then 3 letters but i have no idea where this is coming from and how do i alter...ideas?
This is coming from the HTML5 browser capabilities. Meaning this validation only works on modern browsers that support validation attributes such as "required", check out some examples here.
If you want browser compliant validation i suggest this plug in. Just remember people can disable JS so if you have sensitive data validate it server-side.
Remove the required="true" from your <input> tags to get rid of that validation.
if you click submit without filling any of the fields you get three
validations but i have no js files included so where is this coming
from
It looks like you are using HTML5 forms code here.
It uses required="true" or required
HTML5 browsers are interpreting this correctly.

If you need some simple validation, you could do something like this
$('#first_name').blur(function(){
if($(this).val().length < '3'){
alert('You must enter three characters');
}
});
Example: http://jsfiddle.net/jasongennaro/ZEjEq/
This is just an example. You could do something like this on submit().
Also, you should validate content on the server side, too. Just to be sure!
