Question

下面的代码将每行的文本拆分为某个分隔符的新创建的行通过改变拼接方法的第二个参数，可以给出起点。起始分隔符出现后的所有内容都将被拆分并放在新的行上

如何仅拆分出界处的第n个出现？（即第二个）

期望的结果应该是这样的：在第二个＆＃39; /＆＃39;开始分裂。定界符：

此：
的 PMC37516JG / DMM / 1946P / C.Q4.DUMMY

变为：
的 PMC37516JG / DMM
1946P / C.Q4.DUMMY

$('#tbl tr').each(function(){
  var $this = $(this);
  var arr = $this.text().split('/');
  var firstTwo = arr.splice(0,2);
  var firstEl = firstTwo.join('/').trim();
  arr.unshift(firstEl);
  var len = arr.length;
  var i;
  var $previous = $this;
  for (i = 0; i < arr.length; ++i) {
    var $tr = $this.clone();
    $tr.find("td").text(arr[i]); 
    $previous.after( $tr );
    $previous = $tr;
  }
  $this.remove();
});

将您的脚本更改为低于1，请验证这是否适合您。

$('#tbl tr').each(function(){
      var tr = $(this).find('td').text().split('/');
    if (tr.length > 2){
    //you can change below code to split it by first '/'
        var p =tr.splice(0,2);
    $(this).replaceWith('<tr><td>' +p.join('/') +'</td></tr> <tr><td>'+tr.join('/') +'</td></tr>') 
    }

    });
