How to Include JQuery via Inspect Console

One day you visit a website, maybe you want to scrape something, count how many elements, or any other thing you normally do easily with javascript. Right click > Inspect > Console tab > try simple command (in this example we want to change all p tag’s text)

$('p').text('hey')

Oops… Unfortunately the website don’t have jquery! Here is how you can inject jquery via the javascript console

var jq = document.createElement('script');
//You can change the JQUERY-VERSION
jq.src = "https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js";
document.getElementsByTagName('head')[0].appendChild(jq);
// ... give time for script to load, then type (or see below for non wait option)
jQuery.noConflict();

i got this trick from developer’s best friend stackoverflow

Now the jquery is available from “jQuery” command, if you’d rather dollar sign $ just assign it

$ = jQuery

The idea is, we create a new script element, and change the source attribute to jquery (or whatever library/js you need later).
