如何在 JavaScript 中将字符串转换为浮点数? [英] How to convert string into float in JavaScript?

问题描述

我正在尝试解析数据网格中的两个值.这些字段是数字，当它们有逗号时(例如 554,20)，我无法获取逗号后的数字.我试过 parseInt 和 parseFloat.我该怎么做?

I am trying to parse two values from a datagrid. The fields are numeric, and when they have a comma (ex. 554,20), I can't get the numbers after the comma. I've tried parseInt and parseFloat. How can I do this?

推荐答案

如果它们是单独的值，试试这个:

If they're meant to be separate values, try this:

var values = "554,20".split(",")
var v1 = parseFloat(values[0])
var v2 = parseFloat(values[1])

如果它们是一个单一的值(比如在法语中，一半写成 0,5)

If they're meant to be a single value (like in French, where one-half is written 0,5)

var value = parseFloat("554,20".replace(",", "."));
