html - 如何使用 JQuery 从动态 html 表中获取选定的行值？

问题描述

我有一个使用 laravel 框架从数据库动态填充的 html 表。

在此处输入图像描述

我在行标题和一个Save Entry按钮中放置了一个复选框。我只想获取表格的选中行值，包括指示计算摘要的表格页脚。

在此处输入图像描述

像这样的东西：

arrbreakdown = []; //push here the checked row values.
arrsummary = []; //push here the calculation summary.

可重现的例子：

<table class="table table-bordered" id="purchasetable">
    <thead>
        <tr>
            <th colspan="7" class="bg-secondary">
                Item Breakdown
            </th>
        </tr>
        <tr class="text-center">
            <th scope="col"><input type="checkbox" onclick="checkallcabin(this)" name="checkall"
                    id="checkall"> </th>
            <th scope="col">Item Name</th>
            <th scope="col">Description</th>
            <th scope="col">Qty</th>
            <th scope="col">UM</th>
            <th scope="col">Item Price</th>
            <th scope="col">Total Price</th>
            <script>
                function checkallcabin(bx) {
                    for (var tbls = $('#purchasetable'), i = tbls.length; i--;)
                        for (var bxs = tbls[i].getElementsByTagName("input"), j = bxs.length; j--;)
                            if (bxs[j].type == "checkbox")
                                bxs[j].checked = bx.checked;
                    setselect();
                }
            </script>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td> <input onchange="enablereqinfo()" id="row1" type="checkbox" name="dtrow"></td>
            <td>TEST 1</td>
            <td><input type="text" style="width:100%" value="TEST DESC 1"></td>

            <td class="totalprice text-right">0.00</td>
        </tr>
        <tr>
            <td> <input onchange="enablereqinfo()" id="row2" type="checkbox" name="dtrow"></td>
            <td>TEST 2</td>
            <td><input type="text" style="width:100%" value="TEST DESC 2"></td>

        <tr>

            <th class="text-right subtotal">0.00</th>
        </tr>
        <tr>
            <th colspan="6">Discount</th>
            <th class="text-right"><input style="max-width:100px;" onkeyup="calculatetotals()" type="number" value="0.00"
                    class="discount text-right"></th>

        <tr>

        </tr>
        <tr>

            <th class="text-right grandtotal">0.00</th>
        </tr>
    </tbody>
</table>

这是我的HTML：

<table class="table table-bordered" id="purchasetable">
    <thead>
        <tr>
            <th colspan="7" class="bg-secondary">
                Item Breakdown
            </th>
        </tr>
        <tr class="text-center">
            <th scope="col"><input type="checkbox" onclick="checkallcabin(this)" name="checkall"
                    id="checkall"> </th>
            <th scope="col">Item Name</th>
            <th scope="col">Description</th>
            <th scope="col">Qty</th>
            <th scope="col">UM</th>
            <th scope="col">Item Price</th>
            <th scope="col">Total Price</th>
            <script>
                function checkallcabin(bx) {
                    for (var tbls = $('#purchasetable'), i = tbls.length; i--;)
                        for (var bxs = tbls[i].getElementsByTagName("input"), j = bxs.length; j--;)
                            if (bxs[j].type == "checkbox")
                                bxs[j].checked = bx.checked;
                    setselect();
                }
            </script>
        </tr>
    </thead>
    <tbody>

    </tbody>
</table>

和我的jQuery：

function getpurchasereqinfo(prid) {
    var val = (prid.value || prid.options[prid.selectedIndex].value);

    $.ajax({
            type: 'POST',
            url: '/dashboard/purchasing/quotation/get-prrequestinfo',
            data: {
                "refid": val,
                "transtype": $('#reqtype').val()
            },
            encode: true,
            dataType: 'json',
            headers: {
                'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
            },
        })
        .done(function (data) {
            var cnt = 0;
            $("#purchasetable > tbody").empty();

            for (i in data.prrequestinfo) {

                cnt = cnt + 1;
                $("#purchasetable > tbody").
                append("<tr>" +
                    "<td> <input onchange='enablereqinfo()' id='row" + cnt +

                    "</tr>"
                );
            }

}

任何想法？谢谢

解决方案

您可以遍历使用循环检查的所有复选框，each然后使用或推送values数组中的行.val().text()

演示代码： 

$("#save").click(function() {
  var arrbreakdown = []; //push here the checked row values.
  var arrsummary = []; //push here the calculation summary.
  //loop through checked checkbox
  $("tbody input[type='checkbox']:checked").each(function() {
    var selector = $(this).closest('tr'); //get closest row
    //push values in array
    arrbreakdown.push({
      "Name": selector.find('td:eq(1)').text(),
      "Description": selector.find('td:eq(2) input').val(),
      "Qty": selector.find('td:eq(3)').text(),
      "UM": selector.find('td:eq(4)').text(),
      "Item_Price": selector.find('.iprice').val(),
      "Total": selector.find('td:eq(6)').text()
    })

  })
  //for summary
  arrsummary.push({
    "Sub_Total": $(".subtotal").text(),
    "Discount": $(".discount").val(),
    "taxtotal": $(".taxtotal").text(),
    "netamount": $(".netamount").text(),
    "grandtotal": $(".grandtotal").text()
  })
  console.log(arrsummary)
  console.log(arrbreakdown)

})
