javascript - 包含文本区域的行跨度表 td

Question

到目前为止，我已经能够将表格行与 td 中的文本合并，但文本区域中的文本尚未通过。我的 table

Column1 | column2 | column3 | Column4
--------------------------------------
 Assay  |  Source | label  |   3%
-------------------------------------
 Assay  |  Source | label  |   10%
-------------------------------------

我想完成什么

Column1 | column2 | column3 | Column4
--------------------------------------  //Note that Column1 has
        |        |         |   3%       //no textarea, just td text
 Assay  - Source -   label -----------  //While all the rest have
        |        |         |   10%      //textareas in the tds
-------------------------------------   // from column 2 - 4

我的这段代码仅适用于没有文本区域的 tds。如何合并具有相同数据的文本区域的行？

function merge() {
  $('.result_table').each(function() {
    var Column_number_to_Merge = 1;

    // Previous_TD holds the first instance of same td. Initially first TD=null.
    var Previous_TD = null;
    var i = 1;
    $("tbody", this).find('tr').each(function() {
      // find the correct td of the correct column
      // we are considering the table column 1, You can apply on any table column
      var Current_td = $(this).find('td:nth-child(' + Column_number_to_Merge + ')');

      if (Previous_TD == null) {
        // for first row
        Previous_TD = Current_td;
        i = 1;
      } else if (Current_td.text() == Previous_TD.text()) {
        // the current td is identical to the previous row td
        // remove the current td
        Current_td.remove();
        // increment the rowspan attribute of the first row td instance
        Previous_TD.attr('rowspan', i + 1);
        i = i + 1;
      } else {
        // means new value found in current td. So initialize counter variable i
        Previous_TD = Current_td;
        i = 1;
      }
    });
  });
}

Answer 1

我不完全确定你要做什么，但它看起来像这样:

if (Current_td.text() == Previous_TD.text())

可以更改为:

 if (Current_td.text() == Previous_TD.text()
      || Current_td.find("textarea").val() == Previous_TD.find("textarea").val())
