我正在尝试遍历表中的价格，并根据下拉菜单中选择的货币更新货币。
我需要能够即时更新价格，以允许用户在不同货币之间进行兑换。我正在使用openexchangerates api使用ajax来获取价格。在我的示例代码中，有硬编码的费率。
到目前为止，我已经能够获取价格字段并将其放入一个数组中，同时从每个价格字段中删除$。
我目前遇到的麻烦是创建一个侦听器，等待您选择一种货币，然后遍历表以执行值*利率的数学运算并相应地更新dom。

只需做（或代替）
jQuery(document).ready(function (t) {
只是
jQuery('#selector').change(function (t) {
// and so on....
