Question

我有一个动态的HTML表。我正在用JSON数据创建它。我要处理一张桌子有几个要求。

有一个按钮view，如果用户单击该按钮，它将显示所有非零行，但是当前它显示在我不想要的同一表中。

我要实现的目标

当用户单击view时，新表应并排填充或在主表下方填充
我已经用非零行数据过滤了现有表
现在，我想通过点击view
该用户可以看到他输入的内容，并可以重新检查他输入的记录

我还尝试了另一种方法，即当用户单击视图时，视图按钮将更改为edit，并且该表将填充非零行，但是当用户单击时，再次编辑表数据重置为0，我曾经并为此使用autocomplete=on，但是在单击“编辑”时，它只是将我的表格数据刷新为0

所以没有解决。现在，我有了一个新的想法，即并排填充一个表以进行查看，另一个并排进行编辑，只是在单击非零数据的查看按钮时面临创建新表的问题。

注意

我尝试使用的每种方法所面临的主要问题是，当用户单击view按钮时，为什么数据会重置为零。

Answer 1

您需要创建第二个表并将所需的行克隆到该表中。

因此您可以添加一个新表，如下所示：

<!-- Add a new table for results -->
<div class="table-responsive">
  <table class="w-100" id="table-result"></table>
</div>

浏览不为空的字段：

var quantityFields = $(".dataReset").filter(function() {
    return this.value!=0;
});

克隆行，将其添加到新表中，然后在第一张表中重置该行：

let row = Object.assign(quantityFields[i].closest(".item-row"));
tResult.append(row);

for (var i = 0; i < quantityFields.length; i++) {
  //COPY CURRENT ROW IN NEW TABLE
  let row = $(quantityFields[i].closest(".item-row")).clone();
  tResult.append(row);
  //RESET THE CURRENT VALUE IN FIRST TABLE
  quantityFields[i].value="0";
//}

}
