AddEventListener: onmousedown

提问by Ryan Hawdon

I am creating a Chrome Extension which checks to see if there is "onmousedown" attribute and if so I will execute some code.

我正在创建一个 Chrome 扩展程序,它检查是否有“onmousedown”属性,如果有,我将执行一些代码。

I have tried this however it isn't working.

我试过这个,但它不起作用。

document.addEventListener("onmousedown", function() {

});

回答by Lorenzo Cinque

is "mousedown" not "onmousedown".

是“mousedown”而不是“onmousedown”。

object.addEventListener("mousedown", myScript);
