使用JQuery的Dev Tools Chrome可以启用/禁用内容

Question

I just figured something out.

I'm using Chrome browser, and if a website is using JQuery you can then use Chrome dev tools to execute javascript to alter the website ie Enable buttons which shouldn't be enabled.

if you run the normal code document.getElementById('myId').disabled = false or document.getElementById('myId').enabled = true then it does nothing.

But as soon as you run $('#myId').attr('disabled', false); then the component actually enables and you are then able to click it.

Is it possible with JQuery to block out these type of executions?

Answer 1

So are you asking if you can use jQuery to prevent people from running additional javascript/jQuery from the browser console? No, you cannot do this, the console is built into the browser for developers to test and experiment with by running additional javascript after/while javascript on the page is running. Same thing goes for other browsers as well.
