I have a script, that takes the value from two select tags, and then do a simple math multipy to calculate a price. The thing I need, but cannot figure out is, how to get that calculated price, and use it as an php variable in a POST form.

由于计算出的价格是动态的，我该如何归档？

As the calculated price is dynamic, how can I archive this?

推荐答案

如果要将该值直接发送给a PHP脚本，你可以使用jQuery post 方法：

If you want to send that value directly to a PHP script, you can use the jQuery post method:

$.post("yourScript.php", { price: yourPriceVar }, function(data) {
    //Success! Do something interesting
});

或者，您可以设置值计算值的隐藏输入元素，以便可以与表单的其余部分一起提交：

Alternatively, you could set the value of a hidden input element to your calculated value, so that it can be submitted along with the rest of your form:

$("#hiddenInput").val(yourPriceVar);

HTML：

<input type="hidden" id="hiddenInput" name="price" />
