我正在使用jquery的计数器插件（http://wplayground.comuv.com/counter/）并在我们的页面中成功实现。但是我需要对它进行调整，我不确定应该去哪里。
基本上，脚本会对字符（或我们的单词）进行计数，并在用户达到目标时停止输入。这部分工作正常。但现在，我需要进行调整，以便在用户输入像example.com这样的URL时，该单词被计为3个单词而不是1.在我们网站的先前版本中，开发人员编写自定义javascript来完成任务，并考虑到URL的事情，他做了以下更改：
if(getWord.indexOf(".com")>=1 || getWord.indexOf(".net")>=1 || getWord.indexOf(".org")>=1 || getWord.indexOf(".biz")>=1 || getWord.indexOf(".gov")>=1 || getWord.indexOf(".edu")>=1 || getWord.indexOf(".mobi")>=1 || getWord.indexOf(".info")>=1 || getWord.indexOf(".ca")>=1 || getWord.indexOf(".us")>=1 || getWord.indexOf(".mil")>=1){///Email
pk1 = pk1+3;
所以，以下是新的jquery计数器。如何调整它来做同样的事情？

答案 0 :(得分：3)
在计数器插件文件的中间，有一行如下所示：
else{
new_length = $.trim($obj.val())
.replace(/\s+/g, " ")
.split(' ').length;
}
似乎这就是它的重要性。它抓住盒子里的文字，分隔空格，然后计算元素。
您可以在此处为网址添加某种检查（正则表达式），然后相应地增加new_length。
像这样（未经测试）：
else{
var str = $.trim($obj.val())
.replace(/\s+/g, " ");
new_length = str.split(' ').length;
var URLs = str
.match(/([^\s])+\.(com|net|org|biz|gov|edu|mobi|info|ca|us|mil)/g);
if(URLs != null && URLs.length > 0){
new_length += (URLs.length*2);
}
}
