javascript - 使用 jquery 迭代表格单元格

问题描述

我有一个 HTML 表格，我需要在其中获取表格所有行的值，在每个表格中都存在具有不同类的单元格。

预期的结果是

[
[false,"A text",12,"textboxvalueifpresent","2019-07-17T14:08:38.911Z","2019-07-04T12:00:00.000Z"],
[true,"B text",88,"","2019-07-17T14:08:38.913Z","2019-07-04T12:00:00.000Z"],
[false,"C text",24,"","2019-07-17T14:08:38.913Z","2019-07-04T12:00:00.000Z"]
]

我已经尝试过每个 Jquery

var items = [];
$("#tab1 tr").each(function() {
        items.push([$(this).find("input.checkbox").val(),
        $(this).find("input.material").val(),
        $(this).find("input.consign").val(),
        $(this).find("input.name").val(),
        $(this).find("input.dc").val(),
        $(this).find("input.do").val(),
        ]);
});
<table id="tab1" style="padding: 5px;width: 100%">
   <tr id="tr1">
      <td class="input checkbox" style="width:5%;cursor:default"><input type="checkbox" id="cb1"></td>
      <td style="width:30%;"><span style="width:100%;" class="input material" id="ma1">A text</span></td>
      <td style="width:10%;"><input type="number" style="width:90%;" class="input consign" id="co1" value="12" placeholder="Consign"></td>

      <td style="width:15%;"><span class="input do" id="do1">2019-07-04T12:00:00.000Z</span></td>
   </tr>

      <td style="width:30%;"><span style="width:100%;" class="input material" id="ma2">B text</span></td>

解决方案

复选框的值是它的value属性中的任何内容，它是否被选中并不重要。您可以使用.prop("checked")or.is(":checked")来判断它是否被选中。

您的复选框没有class="checkbox", so.input.checkbox won't work. I changed it to.input:checkbox`。

跨度不会被选择input器选择，你会得到文本.text()，而不是.val()。

你没有class="dc"在第五列，它是class="dr".

$("#button").click(function() {
  var items = [];
  $("#tab1 tr").each(function() {
    items.push([
      $(this).find("input:checkbox").prop("checked"),
      $(this).find("span.material").text(),
      $(this).find("input.consign").val(),
      $(this).find("input.name").val(),
      $(this).find("span.dr").text(),
      $(this).find("span.do").text(),
    ]);
  });
  $("#output").text(JSON.stringify(items, null, 2));
});
