JS数组中怎么不区分大小写排序？

[yi_piao]

var a=["c","B","a","f","E"];

数组a怎么排序，使其变成a=["a","B","c","E","f"],最好告诉我用Array.sort()方法应该怎么写代码?

[lihaoran8577]

将其转化数组全部转化为大写或小写,在进行排序！？

不理解，有代码没?

[Mr-Jee]

var a=["c","B","a","f","E"];
alert(a.sort(function(i,j) {
return j.toLowerCase() < i.toLowerCase();
}));

var arr=["c","B","a","f","E"];
arr.sort(function(a,b){return a.toLowerCase()>b.toLowerCase()?1:-1;});
alert(arr);

这个不对！！！！

["c","B","a","f","E"].sort(function(a,b){
	return a.toLowerCase().localeCompare(b.toLowerCase());						   
})
