jQuery getJSON - 可能的语法错误
好吧，我已经设法将各种示例中的以下内容放在一起，但是我什至不相信 javascript 函数被调用，下面是我的所有代码：
Javascript：
<script type="text/javascript" src="coding/jquery.js"></script>
<script type="text/javascript">
function showHint(quantity, price){
document.getElementById("txtcost").innerHTML="being called values" + quantity + price;
$.getJSON('http://website.com/ecommerce/coding/validation/calprice.php', {q: quantity, p: price}, function(data){
$('#txtcost').html('Total: ' + data.total);
$('#txtvat').html('VAT: ' + data.vat);
});
}
</script>
显示
<span id="txtcost" style="color:#060"></span>
<span id="txtvat" style="color:#060"></span>
PHP
<?php
echo "being called";
function data() {
$q = $_GET["q"];
$p =&$_GET["p"];
$total = $p * $q;
if($q >= 10)
{
$total = ($total / 10) * 9;
//echo '<strong>£ ' . $total . '</strong><span style="font-size:10px; font-weight:bold;"> Discount applied.</span>';
echo json_encode(array('total' => $total, 'vat' => '10.00'));
}
else{ echo '<strong>£ ' . $total . '<strong>'; }}
?>
希望有所帮助
注意：代码并不完美，我想让初始功能正常工作。
编辑：
到目前为止我已经设法建立：
该函数正在被调用 正确的值被传递到函数中
Well I've managed to put the following together from various examples, however I don't believe the javascript function is even being called, below is all my code:
Javascript:
<script type="text/javascript" src="coding/jquery.js"></script>
<script type="text/javascript">
function showHint(quantity, price){
document.getElementById("txtcost").innerHTML="being called values" + quantity + price;
$.getJSON('http://website.com/ecommerce/coding/validation/calprice.php', {q: quantity, p: price}, function(data){
$('#txtcost').html('Total: ' + data.total);
$('#txtvat').html('VAT: ' + data.vat);
});
}
</script>
Display
<span id="txtcost" style="color:#060"></span>
<span id="txtvat" style="color:#060"></span>
PHP
<?php
echo "being called";
function data() {
$q = $_GET["q"];
$p =&$_GET["p"];
$total = $p * $q;
if($q >= 10)
{
$total = ($total / 10) * 9;
//echo '<strong>£ ' . $total . '</strong><span style="font-size:10px; font-weight:bold;"> Discount applied.</span>';
echo json_encode(array('total' => $total, 'vat' => '10.00'));
}
else{ echo '<strong>£ ' . $total . '<strong>'; }}
?>
Hope that helps
Note: the code isn't perfect, I want to get the initial functionality working.
EDIT:
SO far I've managed to establish:
The function is being called
The correct values are being passed into the function

一方面，您需要使用 JavaScript 的点表示法来引用对象属性，而不是 PHP 的箭头运算符：
而不是
For one thing, you need to use JavaScript's dot notation to reference object properties, and not PHP's arrow operator:
instead of
我认为你在第 1 行的引用有问题，你似乎正在闯入 php，也许你需要使用更像是的东西：
但如果没有完整的代码很难说
i think a problem with your quotes on line 1 you seem to be breaking into php, maybe you need to use something more like:
but hard to say without full code
