JS_驼峰式和连字符式的转换

1.驼峰转连字符:

   var s = "fooStyleCss";
  s = s.replace(/([A-Z])/g,"-$1").toLowerCase();

//利用正则进行替换,简洁明了,很棒

2.转驼峰

var s1 = "foo-style-css";
s1 = s1.replace(/\-(\w)/g, function(all, letter){
          return letter.toUpperCase();
        });

//这段2看的不是很明白

于是自己写一个,^_^,这个很容易懂吧,就是代码多了点;

var s = "style-sheet-base";

var a = s.split("-");
var o = a[0];
for(var i=1;i<a.length;i++){
    o = o + a[i].slice(0,1).toUpperCase() + a[i].slice(1);
}

再写一个,这次用正则:

var s1 = "style-sheet-base";
s1 = s1.replace(/\-(\w)/g, function(x){return x.slice(1).toUpperCase();});

哈哈,有意思吧
