好的,如果客户在下拉菜单中选择1个礼品,1个产品和英国,价格加起来为18.48英镑,但当他们输入某个邮政编码(列在数组中)时,它应该额外增加2.00英镑它总共使得20.48英镑。但是当按下结帐时它只能带来18.48英镑....这是因为数组没有被添加到下面的公式总额中吗?

var firsttwo = pc.substr(0, 2);
firsttwo = firsttwo.toUpperCase();
//alert(firsttwo);
var a = postcode_arr.indexOf(firsttwo);
if (a != -1) {
var amt = parseFloat(document.getElementById("amount").value);
amt += 2;
document.getElementById("amount").value = amt;

document.getElementById("demo").innerHTML = a;

答案 0 :(得分:0)
很难理解这里发生了什么,但似乎myFunction
仅在邮政编码元素的模糊上被调用。意味着必须先选择它,然后取消选择,这会触发模糊。
我猜这个触发器不会发生。因此,您必须确保使用邮政编码输入元素的当前值调用-s EXPORT_NAME="'SomeModuleName'"
。
