javascript - How can I execute js functions onClick just after form is loaded -

i have form , 2 buttons:

<input type="button" name="btn" onclick="a()" value="--->"><br> <input type="button" name="btn" onclick="b()" value="<---"> 

in javascript.js file have:

function a(){ console.log("a"); } function b(){ console.log("b"); } 

i want call function (just when click buttons) when document loaded. how can do?

code included inside $( document ).ready() run once page document object model (dom) ready javascript code execute.

$(document).ready(function(){      a(); //executes function on dom load      b(); // executes function b on dom load }); 

you can use $( window ).load(), gets executed after entire page (images or iframes), not dom, ready.

$(window).load(function(){      a(); //executes function on page load      b(); // executes function b on page load });
