jquery – Internet Explorer,Closure Compiler和Trailing Commas

我正在使用html5boilerplate构建脚本并在缩小脚本时(使用Google Closure Compiler)

我收到了这个错误

-js.all.minify:
     [echo] Minifying scripts
     [copy] Copying 3 files to /Users/Username/Desktop/Web/intermediate/js
    [apply] /Users/Juan/Desktop/Web/js/plugins.js:117: ERROR - Parse error. Internet Explorer has a non-standard intepretation of Trailing commas. Arrays will have the wrong length and objects will not parse at all.
    [apply]                 },{ duration: 727 })
    [apply] 

             ^

但如果运行未编译,代码将在IE 8中运行.

这是代码

anim1.animate({
                    'left': '+=32px','filter': 'alpha(opacity=100)','-moz-opacity': '1','-khtml-opacity': '1','opacity': '1',},{ duration: 727 })

如何让这段代码通过Compulsure Compiler？

谢谢

anim1.animate({
    'left': '+=32px','opacity': '1'      // <-- No comma here.
},{ duration: 727 });  // <-- I'd also suggest a semicolon there.
