在JavaScript的getElementbyId上转义连字符

Question

I want to pass -webkit-background-clip property with javascript.

Because of the hyphen at start, I cant seem to get it right. Tried it with [, ", ' etc. How do I escape dash?

document.getElementById("menu").style.-webkit-background-clip = "text";

Answer 1

You can use bracket notation...

document.getElementById("menu").style["-webkit-background-clip"]

...or use camel case...

document.getElementById("menu").style.webkitBackgroundClip 

jsFiddle .

Note that JavaScript resolves these to different names, but the browser supports both.

Answer 2

尝试document.getElementById("menu").style["-webkit-background-clip"] = "text";
