我正在生成一个包含待售产品的表格,一个用于选择产品数量的输入,以及一个用于处理每行购买的按钮。然后我正在进行AJAX调用以处理所有这些数据,并显示一个显示数据的模态对话框。
类似的东西:
产品单位价格编号
产品A 12 [输入金额] [购买按钮]
我打算获得一个模式,“你已经为$ *购买了*项目。”
工作正常,但当我尝试捕获输入值以显示项目数时,这一切都会被破坏。
这是表格主体:
<?php
foreach ($result as $doc) {
$price = $doc['2'];
$name = $doc['1'];
$rd_price = round($price, 2);
?>
<tr>
<td><?php echo $name; ?></td>
<td class="product_price"><?php echo $rd_price; ?></td>
<td><input type="text" name="qty" class="product_qty" value="0"></td>
<td class="amount_sub_total">0</td>
<td><button data-toggle = "modal" data-target = "#myModal" id="<?php echo $name; ?>" value="<?php echo $rd_price; ?>" onclick="showDetails(this)">
<i class="fas fa-shopping-cart"></i>
</button></td>
</tr>
<?php } ?>
</tbody>
脚本:
<script>
function showDetails(button) {
var customerNumber = button.id;
var customerPrice = button.value;
var selectedAmount = $(.product_qty).val();
$.ajax({
url: "customer.php",
method: "GET",
data: {"customerNumber": customerNumber, "customerPrice": customerPrice, "selectedAmount": selectedAmount},
success: function(response){
$("#value").text(response);
}
});
}
</script>
如果有人能帮助我,我会非常感激。

你错过了报价&#34;&#34;。 改变这个
$(".product_qty").val();
到这个
id
如果您使用class
代替product_qty
css选择器
类似于将button_id与$("#product_qty_"+button.id).val();
<input type="text" name="qty" class="product_qty" value="0" id="'product_qty_'+<?php echo $name; ?>">
并将html更新为
if keydown in [enter, ","]:
// logic of function "doneTyping"
text = parse(text) // get text from textarea and grab latest value
if text is valid:
renderTag(text) // put the text in a tag element
updateHiddenForm(text) // update the hidden form to include the tag
else:
notifyUserOfInvalidTag(text) // alert user
else:
// logic of function "stillTyping"
suggest = bloodhoundSearch(text) // use twitter typeahead
updateSuggestionBox(suggest) // display results from typeahead

你遗漏了一些东西。
