Javascript: Automatically clicking a button?
提问by KingPolygon
I'm learning how to write a chrome extension, and I'm fairly new to javascript.
我正在学习如何编写 chrome 扩展程序,而且我对 javascript 还很陌生。
Here's some html:
这是一些html:
<div class="button data" style="">
<a class="button1 whiteColor" href="http://link1.com">VIEW This</a>
<a class="button2 redColor" href="http://link2.com">VIEW That</a>
</div>
What I want to do is open link2.com by automatically clicking button2 using javascript.
我想要做的是通过使用 javascript 自动单击 button2 来打开 link2.com。
I'm using the following, but it's not working :/
我正在使用以下内容,但它不起作用:/
document.getElementByClassName("button2 redColor").click();
Any help would be appreciated!!
任何帮助,将不胜感激!!
