Link types are actions that can be taken on click of a link or button. The following link types are available by default.

Each of these generate a URL with required input from the user. For example, Open Website asks the user for a URL and Target.

Adding a New Link Type

You can add your own link types. Every link type has the ability to add a URL to href or a JavaScript function to the onClick method of the link or button HTML tag. This could be a simple static URL, or a URL generated with user input.

You have to define the following parameters for each link type.

Parameters

Name	Description
name	Unique name for the link type
label	Display label for the link type
attrs	An object where we define the link value. For URL based links, it will have href and target. For JavaScript links, this will have onClick.
fields	This is where we will define the input fields that the user can fill to generate the URL. Check the input field parameters below.

Input Field Parameters

If you need to get input from users to create the URL for your link, this is how you can define the fields.

Name	Description
name	Unique name for the input field
label	Display label for the input field
defaultValue	Default value for the input field
inputType	Input type for the field. This is the HTML input type. Examples: `text`, `email`, `number`, etc.
placeholderText	Placeholder text for the input field
options	Only required for dropdown. An array of objects containing all the option labels and values.

Examples

Here are a few examples that demonstrate different link types.

Static Link

In this example, we will add a simple https://google.com static link as an available link type. If a user selects this action, the button will simply open Google in a new tab.

unlayer.setLinkTypes([
  {
    name: "static_google_link",
    label: "Go to Google",
    attrs: {
      href: "https://google.com/",
      target: "_blank"
    },
  }
]);

Input Generated Link

In this example, we will ask the user to enter an email and choose a country to generate the link URL. The link would look like: https://mycustomlink.com/[email protected]&country=usa

For this, we will have to define these 2 input fields.

unlayer.setLinkTypes([
  {
    name: 'my_custom_link_type',
    label: 'Custom',
    attrs: {
      href: 'https://mycustomlink.com/?email={{email}}&country={{country}}',
      target: '_blank',
    },
    fields: [
      {
        name: 'email',
        label: 'E-mail',
        defaultValue: '',
        inputType: 'email',
        placeholderText: null,
        options: [],
      },
      {
        name: 'country',
        label: 'Country',
        defaultValue: 'usa',
        inputType: null,
        placeholderText: null,
        options: [
          { value: 'usa', label: 'United States' },
          { value: 'other', label: 'Other' },
        ],
      },
    ],
  }
]);

JavaScript onClick Link

In this example, we will define a link type that uses JavaScript onClick instead of href. This is useful if you are using our landing page builder.

unlayer.setLinkTypes([
  {
    name: 'my_custom_alert',
    label: 'Show Alert',
    attrs: {
      onClick: 'alert("Hello World")'
    }
  }
]);

Disable Defaults

You can disable the default link types.

unlayer.setLinkTypes([
  {
    name: 'phone',
    enabled: false
  },
  {
    name: 'email',
    enabled: false
  },
  {
    name: 'sms',
    enabled: false
  }
]);
