我有一份商店物品清单。每个项目都以一种形式显示其价值。
<?php
if($statement->execute())
{
$result = $statement->fetchAll();
$output = '';
foreach($result as $row)
{
$output .= '
<div class="col-md-3" style="margin-top:12px;">
<div class="item-content" align="center">
<div class="img-container">
<img src="../administrar/application/admin/productos/'.$row["image"].'" class="img-responsive" /><br />
<h4 class="text-info">'.$row["name"].'</h4>
<h4 class="text-danger">$ '.$row["price"] .'</h4>
<input type="text" name="quantity" id="quantity' . $row["id"] .'" class="form-control" value="1" style="text-align:right;"/>
<input type="hidden" name="hidden_name" id="name'.$row["id"].'" value="'.$row["name"].'" />
<input type="hidden" name="hidden_price" id="price'.$row["id"].'" value="'.$row["price"].'" />
<div class="input-group">
<span class="input-group-btn">
<button type="button" class="btn btn-danger btn-number" name="restar" id="'.$row["id"].'" " >
<span class="glyphicon glyphicon-minus"></span>
</button>
</span>
<span class="input-group-btn">
<button type="button" class="btn btn-success btn-number" name="sumar" id="sumar"">
<span class="glyphicon glyphicon-plus"></span>
</button>
</span>
</div>
我需要确定用户何时单击某个表单项中的“重新启动”按钮。
这是我当前的脚本,但它没有启动预期的警报。
<script type="text/javascript">
$(document).ready(function(){
var product_id = $(this).attr("id");
$('#restar'+'product_id+').on('click', function(event) {
alert("ssssspp2");
});
});
</script>
