使用js数组进行不区分大小写的排序

Question

我今天写了这个并且工作正常，但是，我注意到大写在排序方面优先考虑...如何在保留原始字符串的同时对这个不区分大小写进行排序？

// original data
var data = 'keyword,another,test,546,Hello';

//if keywords then split them by comma into an array
var keyArray = new Array();
keyArray = data.split(",");

// sort the new array alpha
keyArray.sort();

// now output as nice display
var keyOut = '';
var keyLength = keyArray.length;
for (var i = 0; i < keyLength; i++) {
    //create output
    var keyOut = keyOut.concat('<span class="label label-default">'+keyArray[i]+'</span> ');
}

return keyOut;

编辑：

在找到一个快速示例并按预期工作后回答了我自己......

keyArray.sort(function (a, b) {
    return a.toLowerCase().localeCompare(b.toLowerCase());
});

您可以这样做：

// original data
var data = 'keyword,another,test,546,Hello';

//if keywords then split them by comma into an array
var keyArray = new Array();
keyArray = data.split(",");

// sort the new array
keyArray.sort(function(a, b) {
        var textA = a.toUpperCase();
        var textB = b.toUpperCase();
        return (textA < textB) ? -1 : (textA > textB) ? 1 : 0;
    });

// now output as nice display
var keyOut = '';
var keyLength = keyArray.length;
for (var i = 0; i < keyLength; i++) {
    //create output
    var keyOut = keyOut.concat('<span class="label label-default">'+keyArray[i]+'</span> ');
}

return keyOut;
