how to validate input field which has name in array type using jquery.validate.min.js

Question

I have input tag fields which has name attribute in array for i.e.

<div class="form-group">
    <label class="col-sm-2 control-label">
        <span style="color: red;">*</span>
        Title</label>
    <div class="col-sm-8 general-title tooltip-demo">

<input type="text" name="form[1][title]" id="title" value="" size="64" class="form-control" data-toggle="tooltip" data-placement="top" data-html="true" title="" required="required" data-original-title="Enter Notification Title">    </div>
</div>
 <div class="form-group">
    <label class="col-sm-2 control-label">
        <span style="color: red;">*</span>
        Title 2</label>
    <div class="col-sm-8 general-title tooltip-demo">

<input type="text" name="form[2][title]" id="title" value="" size="64" class="form-control" data-toggle="tooltip" data-placement="top" data-html="true" title="" required="required" data-original-title="Enter Notification Title">    </div>
</div>

I know, i can do validation like

$(document).ready(function() {
    $("#frmforgot").validate({
        rules: {
            form[1][title]: {
                required: true
            },
            form[2][title]: {
                required: true
            }
        }
    });
});

But i don't want to separate each validation rule, because i have 30 different fields so i don't want to write 30 * 2 rules.

If anyone know easy way, please suggest me.

Thanks in advance

You can use the .rules() method to assign any rules to the fields in bulk.

It's this simple...

$(document).ready(function() {

    $("#frmforgot").validate();

    $('input[name^="form"]').each(function() {
        $(this).rules('add', {
            required: true
        });
    });

});

In your case, it does not matter that the naming is using array format. The input[name^="form"] selector is looking for any input with a name starting with the letters form.

It's a moot point since you already have required="required" on those input elements, so you do not need to assign this rule again. The jQuery Validate plugin will simply use any HTML5 attribute to assign the corresponding rule automatically.

You could create your rules before you pass them into the validate function -

var rules = {};
$('input[name^=form]:text').each(function() {
    rules[this.name] = { required: true };
});

$(document).ready(function() {
  $("#frmforgot").validate({
    rules: rules
  });
});

what if i have email field and required, email validation. Also in your answer "input[name^=form]" which is not in array format so i don't thinks it works

dmoo Over a year ago

Why would it be in array format? rules is an object, even in your example. If you have additional requirements, please update the question.
