jquery - 拆分和计算字符？

Question

我正在尝试根据特定字符拆分字符串，然后计算每个部分中的字符数。有没有办法做到这一点？

所以，我有：

HTML

<a href="#" class="splitMe" title="Testing | this out">blah</a>

jquery的

$(document).ready(function() {
   $('.splitMe').each(function() {
      var item = $(this).attr('title');
      var characters = item.split("|");

      // Here's where I get stuck... 
      // Tried various methods of length, but haven't been able to get it to work

      // Most recent version that failed miserably... 
      var first = characters[0].text().length;
      var second = characters[1].text().length;

      alert(first+" "+second); //Yields characters[0] is not a function
   });
});

你脑子里有太多的jQuery：

var first = characters[0].length;
var second = characters[1].length;

characters是一个字符串的数组，而不是jQuery对象。字符串没有.text()方法，它们已经是文本。只需访问他们的length财产。
