我试图从动态表中删除行。我成功地从JavaScript中删除了新行。
的JavaScript
$(document).ready(function() {
// table #pos add-row
$(".add-row").keypress(function(e) {
if (e.which == 13) {
var barcode = $("#barcode").val();
$.ajax({
type: "post",
url: "production/ajax/load.php",
dataType: "json",
data: {
barcode: $("#barcode").val()
},
success: function(data) {
$("#pos tbody").append(data['content']);
}
});
}
});
// Find and remove selected table rows
$(".delete-row").click(function(){
alert('Success');
$("#pos tbody tr").remove();
});
})
load.php
<?php
if (isset($_POST['barcode'])) {
require '../controller/connection/connection-management.php';
$barcode = $_POST['barcode'];
$status = false;
$sql = "SELECT code, title, wri_name, pub_name, year, main_category.main_category, category.category, call_number, pusat_penerbit, mrican, paingan, selling_price, discount FROM product, writer, publisher, main_category, category WHERE product.writer = writer.writer AND product.publisher = publisher.publisher AND product.main_category = main_category.main_category AND product.category = category.category AND code = '{$barcode}' ORDER BY title";
$result = mysqli_query($conn, $sql);
if (mysqli_num_rows($result) == 1) {
while($row = mysqli_fetch_assoc($result)) {
$barcode = $row['code'];
$title = $row['title'];
$sellingPrice = number_format($row['selling_price'], 0, ',', '.');
$quantity = 1;
$discount = $row['discount'];
$total = number_format((($row['selling_price'] - ($row['selling_price'] * ($discount / 100))) * $quantity), 0, ',', '.');
$append = "<tr class='pointer'>
<td align='right'><a href='javascript:;' class='delete-row'><i class='fa fa-trash'></i></a></td>
<td><small>{$barcode}</small></td>
<td><div style='text-align: justify'><strong>{$title}</strong></div></td>
<td align='right'>{$sellingPrice}</td>
<td align='center'><input id='quantity' type='text' class='form-control' style='text-align:center' value='1'></td>
<td align='center'><input type='text' class='form-control' style='text-align:center' value='{$discount}'></div></td>
<td align='right'>{$total}</td></td>
</tr>";
}
$status = true;
}
$data = array(
"status" => $status,
"content" => $append
);
echo json_encode($data);
}
?>
pos.php 它的html表格
<div class="x_title">
<div class="input-group">
<span class="input-group-btn">
<button type="button" class="delete-row btn btn-primary"><i class="fa fa-pencil-square-o"></i></button>

<input name="barcode" id="barcode" type="text" class="add-row form-control" placeholder="Enter item name or scan barcode">

</div>
<div class="x_content">

所以当我在表格中添加新行时,一切都很好,就像这张图片一样:
但是当我点击带有class =&#39; delete-row&#39;的垃圾桶图标时,该功能无效。所以我认为,当我将数据附加到表tbody时,它不会从新行读取类或id。
请有人帮忙。我找不到像我这样的类似问题。我只是想知道,当我点击JavaScript中的垃圾桶图标时如何删除表格行。
答案 0 :(得分:4)
这里有两个问题(这就是为什么我没有投票以复制方式结束)。首先,您需要在.delete-row
元素上使用委托事件处理程序,因为它在加载后附加到DOM。当您尝试在元素存在之前附加事件处理程序时,您当前的代码不执行任何操作。
其次,您需要使用DOM遍历来删除仅单击按钮的父tr
。目前,您的代码将删除所有行。试试这个:
$('#pos').on('click', '.delete-row', function() {
$(this).closest('tr').remove();
});

您是否尝试过委托?
$(document).delegate('.delete-row', 'click', function(){
//your remove code here
});
您也可以使用on(对于jquery版本1.7.1 +)
$(document).on('click', '.delete-row', function(){
//your remove code here
});
