如何使用javascript排序日期对象tablesorter？

Question

我想排序表中的一个表中的javascript日期对象。日期的格式为mm/dd/yyyy hr：min a.m.当我尝试按日期排序时，点击标题，什么也没有发生。我可以根据其他列进行排序。 console.log语句是为了调试目的而添加的 - 您可以忽略这些语句。

$.tablesorter.addParser({ 
     id: "customDate", 
     is: function(s) { 
      //return false; 
      //use the above line if you don't want table sorter to auto detected this parser 
      //else use the below line. 
      //attention: doesn't check for invalid stuff 
      //2009-77-77 77:77:77.0 would also be matched 
      //if that doesn't suit you alter the regex to be more restrictive 
      var passes = /\d{1,2}\/\d{1,2}\/\d{1,4}\s\d{1,2}:\d{1,2}\s[ap]\.m\./.test(s); 
      return passes; 

     }, 
     format: function(s) { 
      s = s.replace(/\-/g," "); 
      s = s.replace(/:/g," "); 
      s = s.replace(/\./g," "); 
      s = s.replace(/\//g," "); 
      s = s.replace(/a\sm/, 1); 
      s = s.replace(/p\sm/, 2); 
      s = s.split(" "); 
      console.log('am or pm: ' + s[5]); 
      console.log('hour == ' + s[3]); 
      if (s[3] == '12' && s[5] == 1){ 
       s[3] = 0; //convert 12am to 0 hours. 
       console.log('new hour -- 12am: ' + s[3]); 
      } 
      else if (s[5] == 2 && s[3] != '12'){ 
       s[3] = parseInt(s[3]) + 12; //convert p.m. hours to military time format if it isn't noon. 
       console.log('new hour -- pm: ' + s[3]); 
      } 
      console.log('minutes: ' + parseInt(s[4])); 
      console.log(); 

     return $.tablesorter.formatFloat(new Date(s[2], s[0], s[1], s[3], s[4],0,0,0)); 
     }, 
     type: "numeric" 
    }); 

Answer 1

嗯，我解决了我自己的问题。如果我在我的日期对象上调用getTime（），它会返回日期的数字值，并且我可以对其进行排序。

这行代码现在看起来像：

return $.tablesorter.formatFloat(new Date(s[2], s[0], s[1], s[3], s[4],0,0,0).getTime()); 

Answer 2

使用UTC date format：20111117，您可以按字母顺序对其进行排序。
