Custom Search Button

You may also specify any clickable DOM element as a trigger to lookup a postcode.

Identify your custom input via the button property.

JavaScript

 
PostcodeLookup.setup({
  context: "#lookup_field",
  apiKey: "ak_test",
  button: "#customButton"
  outputFields: {
    line_1: "#first_line",
    line_2: "#second_line",
    line_3: "#third_line",
    post_town: "#post_town",
    postcode: "#postcode"
  },
});

    <h1>Address Form</h1>
