jquery.validateWrapper v1.19.1

This validateWrapper plugin will run above the JQuery Validate Plugin.

Basically, the validateWrapper plugin will help you to validate form elements by adding a few lines of code. Just use the form selector and call the validateWrapper plugin and the form will start validating. This will help the developers to maintain a single file for all the form. It will also help the developers in terms of code redundancy, latency, and many other aspects.

Below is the documentation please follow them to get started with Jquery.validateWrapper.

    //Your logic comes here.
    },
});

unhighlight. If you want to unhighlight any element when the field is validation is successful, then you can add that logic here.

$('form').validateWrapper({
    unhighlight : function (element, errorClass, validClass) {
        //Your logic comes here.
      },
});

invalidHandler. Invalid field handling is done here.

$('form').validateWrapper({
    invalidHandler  : function (form, validator) {
        //Your logic comes here.
      },
});

errorPlacement. If you want to place the error as per your convenience then you can write the logic here.

validateOnLoad If you want to validate the form on load then you need to set it as true.

$('form').validateWrapper({
    validateOnLoad    : true
});

validateOnClick. If you want to validate the form on click of an element then you need to set it as true and add class _validate_oc to the element on which you want to trigger validation.

<button type="button" name="Button" class="btn btn-primary _validate_oc">Button</button>

$('form').validateWrapper({
    resetValidator    : true
});

<button type="reset" name="reset" class="btn btn-primary _reset_validator">Reset Button</button>
<button type="button" name="button" class="btn btn-primary _reset_validator">Button</button>

destroyOnCallback If you want to destroy the Validator once the callback function is executed, then you need to set it as true.

$('form').validateWrapper({
    destroyOnCallback    : true
});

addToValidator If you want to add any other validation functions which are not present in the wrapper or you want to set your own validation functions, then you have to create a method and add the method to addToValidator.

$('form').validateWrapper({
    addToValidator  : function (form,validator) {
        additionalMethods(form,validator);
    },
});

//function name can be anything.
function additionalMethods(form,validator){
    //adding color to the filled element in the form
    $( "input:filled, textarea:filled, select:filled" ).css( "background-color", "#bbbbff");
}

$('form').validateWrapper({
    onComplete  : function (form,event) {

    },
});

messages If you want to add new error messages or modify the existing messages then it has to be set here.

$('form').validateWrapper({
    messages: {
        required    : "Please don't keep the field empty.", //modifying the message.
        valid_email : "Please enter valid email."  //adding new validator Message for custom validation method.
      },
});

groups If you want to have a group validation then it can be done using groups. Please follow the steps to set up group validation.

Step 1: Create a groupName in groups and add the fields you want to group together against the groupName.

$('form').validateWrapper({
    groups: {
        g_name_group: "first_name last_name" //g_name_group is a groupName
    }
});

Step 2: Set the groupName as a class into the fields which are grouped together.

<input type="text" class="form-control g_name_group " id="first_name" name="first_name" required="true" />

<input type="text" class="form-control g_name_group " id="last_name" name="last_name" required="true" />

Step 3: Add class group-in-one to all the elements which are grouped together.

<input type="text" class="form-control g_name_group group-in-one" id="first_name" name="first_name" required="true" />

<input type="text" class="form-control g_name_group group-in-one" id="last_name" name="last_name" required="true" />

Step 4: Adding custom messages to each group.

$('form').validateWrapper({
    messages: {
        g_name_group: "Group message"
    }
});

Note: You can have multiple groups with unique groupName. So to keep them unique so we follow a convention to set up groups. So the group name will start with a 'g_' followed by group_name.

require_from_group Sometimes you need to validate only a few fields from the group then you can use require_from_group option to do that. require_from_group ensures a given number of fields in a group are complete. To set up require_from_group validation you have to follow below steps.

Step 1: Add class require_from_group to all the elements on which you want to perform require_from_group rules.

<select class="form-control require_from_group" name="day" >
    <option value="">--Please Select--</option>
</select>
<select class="form-control require_from_group" name="month" >
    <option value="">--Please Select--</option>
</select>
<select class="form-control require_from_group" name="year" >
    <option value="">--Please Select--</option>
</select>

Step 2: Create a groupName in require_from_group and add the number of fields you want to validate from the group.

$('form').validateWrapper({
    require_from_group:{
        rfg_dob_group : 2,
    },
});

Step 3: The groupName which is created above, add that groupName as a class for the elements. This will identify each group uniquely.

<select class="form-control rfg_dob_group require_from_group" name="day" >
    <option value="">--Please Select--</option>
</select>
<select class="form-control rfg_dob_group require_from_group" name="month" >
    <option value="">--Please Select--</option>
</select>
<select class="form-control rfg_dob_group require_from_group" name="year" >
    <option value="">--Please Select--</option>
</select>

Step 4: Adding custom messages to each group.

$('form').validateWrapper({
    messages: {
        rfg_dob_group: "Group message"
    }
});

Note: group name has to be unique so we follow a convention to setup require_from_group rule. So the group name will start with an 'rfg_' followed by group_name.

showErrors Show Errors will add the message to the element programmatically.

$('form').validateWrapper({
    showErrors: {
        "first_name": "First Name should be written in 'Pete Pete' format."
    }
});

Included additional validation methods.

age Age validation is added in this validateWrapper plugin. This will allow the user to enter only numbers and the number cannot be greater than 3 digits.

<input type="number" class="form-control" id="age" name="age" age="true" />

ckeditor_required To validate ckeditor using Jquery validator it is not straight forward. You have to do some settings to validate ckeditor. This wrapper will skip that step for you and allow you to validate ckeditor by just adding an attribute ckeditor_required as true.

<textarea name="content" ck-editor="true" id="content" ckeditor_required="true" ></textarea>

hide-validation-message If you don't want to display the error message when the field is validated then you can use hide-validation-message = true as an attribute for the element.

<input type="text" class="form-control" hide-validation-message=true id="username" name="username" required="true" />

append-msg-to-parent By default, the error message will be appended to the element. But in certain case you want the error message to be appended to its parent element, then you can set append-msg-to-parent as an attribute to the element and set the value to true.

<input type="text" class="form-control" append-msg-to-parent=true id="username" name="username" required="true" />

Setting other jQuery Validator options. You can set all the jQuery Validator options in the validateWrapper plugin.
