字串首字母大寫

//這個我也一直在糾結，英文標題，即使是首字母大寫，也未必每一個單詞的首字母都是大寫的，但是又不知道哪些應該大寫，哪些不應該大寫
//ecDo.titleCaseUp('this is a title')
//"This Is A Title"
titleCaseUp: function (str, splitType) {
    var _splitType = splitType || /\s+/g;
    var strArr = str.split(_splitType),
        result = "", _this = this
    strArr.forEach(
 
function (item) {
        result += _this.changeCase(item, 1) + ' ';
    })
    return this.trim(result, 4)
}

字串找出最長單詞

//ecDo.longestWord('Find the Longest word in a String')
//result：7
//ecDo.longestWord('Find|the|Longest|word|in|a|String','|')
//result：7
longestWord: function (str, splitType) {
    var _splitType = splitType || /\s+/g,
        _max 
 
= 0,_item='';
    var strArr = str.split(_splitType);
    strArr.forEach(function (item) {
        if (_max < item.length) {
            _max = item.length
            _item=item;
        }
    })
    return {el:_item,max:_max};
}
