将两个参数传递给Javascript函数

Question

Really really silly question, but I can't get this to work:

http://jsfiddle.net/t4R46/

function showOne(parentid, childid){
alert(parentid);
alert(childid);
}

<a href="#" onClick=showOne('div1', 'div2')>91</a>

Basically I want two parameters to be passed to the function but I get: "Uncaught SyntaxError: Unexpected token }"

Is there any smart site to verify javascripts in? The error reporting in ie Chrome leaves a bit to be desired.

Answer 1

You need quotes around the attribute value:

<a href="#" onClick="showOne('div1', 'div2')">91</a>
<!--      here -----^   and here -----------^    -->

In HTML, an attribute value can only not have quotes if it doesn't have spaces (or a few other characters) in it. Since the value you want to set has a space in it, you need to put it in quotes.

You're looking for "lint" tools. Probably the most famous lint tool for JavaScript is Crockford's jslint . But it is heavily influenced by his personal style and opinions, so there's an active fork called jshint that's very popular. There are online and command-line versions of both. Some IDEs offer lint options as well, such as WebStorm from JetBrains.
