My Goal is to validate a specific text field where this field is dependent to the value of the other element.
For example i have select tag and input text tag,
input text is required when select tag has a selected value.
hope someone could help.
Take a look at
In our project we are using, Backbone validator, integrated with Bootstrap
Sample of integration Backbone.validation & Bootstrap
[jsfiddle.net/thedersen/c3kK2/][1]
That is if you are using Backbone :)
For bootstrapvalidator there is a callback method for validation
http://bootstrapvalidator.com/validators/callback/
From example:
<input type="text" class="form-control" name="captcha"
data-bv-callback="true"
data-bv-callback-message="Wrong answer"
data-bv-callback-callback="checkCaptcha" />
And JS
function checkCaptcha(value, validator) {
// Determine the numbers which are generated in captchaOperation
var items = $('#captchaOperation').html().split(' '),
sum = parseInt(items[0]) + parseInt(items[2]);
return value == sum;
};
$(document).ready(function() {
// Return a random number between min and max
function randomNumber(min, max) {
return Math.floor(Math.random() * (max - min + 1) + min);
};
// Generate a sum of two random numbers
function generateCaptcha() {
$('#captchaOperation').html([randomNumber(1, 100), '+', randomNumber(1, 200), '='].join(' '));
};
generateCaptcha();
$('#callbackForm').bootstrapValidator();
});
You can implement arbitrary validation with it.
So your validation can be implemented through some global function
With HTML
<input type="text" class="form-control" name="captcha"
data-bv-callback="true"
data-bv-callback-message="Wrong answer"
data-bv-callback-callback="specialValidation" />
with JS
function specialValidation(value, validator) {
// Determine the numbers which are generated in captchaOperation
var items = $('#otherField').txt();
return value == sum;
};
And you need to be creative with element attributes, to link related elements correctly.
