大家好，我需要帮助然后我有一个表单，通过一个javascript函数，我计算产品的总数，然后邮寄现在我想计算这个值的增值税，但它不起作用，我明白为什么，也许，给我的值是一个值而不是一个数字，例如，他给我100欧元…不是100，然后我想知道，这是一个将数字提取到那个值然后让他计算增值税的系统谢谢你
我想这就是你需要的。
尝试爆炸()。这个函数返回一个字符串数组。
$valueWithCurrency = "100 Euros";
$extractedValue = explode(' ', $valueWithCurrency); //space as a delimiter in first argument
echo $extractedValue[0]; //Here you go. "100"
echo $extractedValue[1]; //this contains "Euros"
对不起。这是我购买的插件代码

这是html
中的调用 // Attaches Simple Price Calc to form
$("#quoteform").SimplePriceCalc();
// Adds Total price and details to hidden inputs that can be used to e-mail data
$("form :input, form textarea, form select").change( function() {
setTimeout( function() {
var total=$('#simple-price-total-num').html();
var details=$('#simple-price-details').html();
$('#hiddentotal').val(total);
$('#hiddendetails').val(details);
}, 150);
});
使用this表示值
echo $_POST['hidden_total']
