Tampermonkey clicking a button by class

Question

So i have a school issue where i need to access a site but this site requires me to go through around 4 portals to get there and am hoping to just write a quick script to do this for me. Problem comes where the site is very sloppy and are written with names being the same on certian buttons so I would like to click the buttons based on class the classes are readit2, readit23, readit239, and readit2394 ``` $(function(){ document.getElementByClassName(readit2).click(); }); ``` the above code i thought would click it as soon as it loads the first page but does not. any help would be great ``` // ==UserScript== // @name dumb spider web // @namespace =============== // @version 0.1 // @description gets me through this dumb stuff // @match =============== // @copyright 2012+, You // @require http://code.jquery.com/jquery-latest.js // ==/UserScript== ``` edit ^ added the header stuff more edits: it works through the console now but through tamper monkey OR grease monkey I can not get it to a…

Accepted Answer

I started looking at all the wrong things, your original code:

```
$(function(){
    document.getElementByClassName(readit2).click();
});
```

The issue with this is that the call should be `getElementsByClassName` (plural "Elements"), since class is usually a shared property. That also returns an array, so if you are positive that there is only 1 ever:

```
$(function(){
    document.getElementsByClassName("readit2")[0].click();
});
```

If not, I'd suggest getting the text and verifying that it contains something that you expect.

Edit: Added quotes.
