如何使用jQuery或Javascript将货币字符串转换为double？ [英] How to convert a currency string to a double with jQuery or Javascript?

问题描述

我有一个文本框，其中包含一个货币字符串，然后我需要将该字符串转换为double以对其执行某些操作。

I have a text box that will have a currency string in it that I then need to convert that string to a double to perform some operations on it.

$ 1,100.00 - > 1100.00

"$1,100.00" -> 1100.00

这需要在所有客户端进行。我别无选择，只能将货币字符串作为货币字符串作为输入，但需要将其转换/转换为double以允许一些数学运算。

This needs to occur all client side. I have no choice but to leave the currency string as a currency string as input but need to cast/convert it to a double to allow some mathematical operations.

推荐答案

删除所有非点数/数字：

Remove all non dot / digits:

var currency = "-$4,400.50";
var number = Number(currency.replace(/[^0-9.-]+/g,""));
