如果从JSON文件（HTML）检索表数据，则来自两个不同表列的值的乘法不起作用

标签： javascript html json

我创建了一个包含静态数据的页面。我在一列中有一个输入框。然后我有一个函数将我在此输入框中输入的值乘以另一列的数字。结果是有效的，如下所示：

h1{
  font-size: 30px;
  color: #fff;
  text-transform: uppercase;
  font-weight: 300;
  text-align: center;
  margin-bottom: 15px;
}
table{
  width:100%;
  table-layout: fixed;
}
.tbl-header{
  background-color: rgba(255,255,255,0.3);
 }
.tbl-content{
  height:300px;
  overflow-x:auto;
  margin-top: 0px;
}

th{
  padding: 20px 15px;
  text-align: left;
  font-weight: 500;
  font-size: 12px;
  color: #fff;
  text-transform: uppercase;
}
td{
  padding: 10px;
  text-align: left;
  vertical-align:middle;
  font-weight: 300;
  font-size: 12px;
  color: #fff;

}

tr:nth-child(odd) td {
  background:#2cc3ce;
  color:#0d3852;
}

现在我正在尝试从JSON文件（url）中检索表数据，然后将单元格值相乘。我在下面创建了一个片段但是JSON数据在这里没有加载，可能是因为url是https。所以请检查LINK。您也可以轻松查看代码段中的代码。

答案 0 :(得分：2)

您正在添加具有相同ID（＆＃34; Memory1＆＃34;）的多个元素（trs），这些元素无效。取决于过滤器的＆＃34;脚本和乘法函数＆＃34;实际上，可能是原因。

编辑：根据您提供的链接，这就是发生的事情：

  1. js / multiply_cells脚本说＆＃34;将事件附加到所有匹配的INPUT＆＃34;

  2. AJAX请求正在更新页面，添加INPUT

    3. 你不希望那些事情按照这个顺序发生。在将INPUT添加到DOM之后调用第一个代码，或者查看event delegation。

    前者是位更简单;尝试这样的事情：

    $.getJSON('http://apolosiskos.co.uk/TEB/MOCK_DATA.json', function(data) {
    var tr;

    $.each (data, function (key, val) {
        tr = $('<tr/>');
        tr.append('<td class="stake"><input class="val1"/>' + '</td>');
        tr.append('<td class="odds">' + val.id + '</td>');
        tr.append('<td class="profit"><span class="multTotal">' +'0.00'+ '</span></td>');
        $('table').append(tr);
    });

    $("input").keyup(multInputs);
});

function multInputs() {
    var mult = 0;

    $("tr").each(function () {
        var $val1 = $('.val1', this).val();
        var $val2 = $('.odds', this).text();
        var $total = ($val1 * 1) * $val2 - $val1
        $('.multTotal', this).text($total.toPrecision(3));
        mult += $total;
    });

    $("#grandTotal").text(mult);
}
