vue-modified

A simple directive plugin for Vue 0.11.x that lets you know when your v-models have been modified. Based off of Vue Validator by Radovan Lozej.

Getting Started

With CommonJS:

var Vue = require('vue'),
    modified = require('vue-modified');

Vue.use(modified);

Standard Usage:

<script type="text/javascript" src="vue.modified.js"></script>

Usage

This plugin is only able to work with elements that you can use v-model with (input, select, textarea, etc) and components.

<input type="text" v-model="email" v-modified>

or with a component:

<mycomponent model="name" v-modified></mycomponent>

With components, you need to provide a special attribute called model with the same content you would place in any other v-model.

If you do not provide the v-modified attribute, this field will not be included in the checks and will not be reported when checking the status of the form.

v-modified Directive

<element v-model="MODEL_NAME" v-modified="GROUP_NAME"> <!-- With group name -->
<element v-model="MODEL_NAME" v-modified> <!-- Without group name -->

This directive may take one argument of a group name. When a group name is provided, it gives the ability to get modified status based on group name and reset the modified status based on group.

Exposed Methods

All exposed methods are available under the create Vue instance that have at least 1 element that contains the v-modified flag.

vm.$modified([group])

Returns Boolean

Whether the form has been modified. Optional group argument may be used to get the modified status for only the fields in that group.

vm.$modified();
vm.$modified('myGroup'); // by group name

vm.$touched([group])

Returns Boolean

Whether any of the fields have been touched on the form. Touching means the value has been at least changed once, even if it is reverted back to it's original value by the user. Optional group argument may be used to get the touched status for only the fields in the provided group.

vm.$touched();
vm.$touched('myGroup'); // by group name

vm.$resetModified([group])

Returns undefined

Resets the modified status of the fields on the form. When the status is reset, it will set modified: false under each field in vm.vmodified along with resetting the internal variable that stores the original value to the fields current value. This is useful if the form is saved via AJAX or an external method is used for resetting/clearing the values in the form. Optional group argument may be used to reset the modified status for only the fields in the provided group.

vm.$resetModified(); // Resets the modified status for entire form
vm.$resetModified('groupName'); // By group only

vm.$modifiedItems([group])

Returns Array

Returns a list of the items being watched by Vue Modified from vm.vmodified. Optional group argument may be used to only return items for that provided group name. If there are no items found, it will return an empty array.

vm.$modifiedItems();
=> [...]

vm.$modifiedItems('groupName'); // By group only
=> [...]
