Odoo javascript onclick event

Question

Is it possible create my own button and this button click call javascript function? Like simple onclick javascript method?

If the answer is yes, how can I do that?

I want to use "Add an item" button or create my own button that calls the same function like I click on "Add an item" button.

Answer 1

First Create button where ever you want to create with some modifications.

<button string="Click" custom="click"/>

Then create one JS file that will contain following code.

odoo.define('YOUR_MODULE.FILENAME', function (require) {
"use strict";

var form_widget = require('web.form_widgets');
var core = require('web.core');
var _t = core._t;
var QWeb = core.qweb;

form_widget.WidgetButton.include({
    on_click: function() {
         if(this.node.attrs.custom === "click"){

            // YOUR CODE

            return;
         }
         this._super();
    },
});
});
