逗号分隔小数的 Javascript 正则表达式

Question

我需要一个匹配货币值的正则表达式，类似于此处:Regex for Money

即'1000'、'1000,0' 和 '1000,00'

但我需要它才能使用 javascript:

 var RE = /^-{0,1}\d*\.{0,1}\d+$/; //validates decimal format such as 1000.50
    if (locale == "fr") {
        RE = \d+(?:,\d{1,2})? //this line fails when validated using the javascript below
    }
    return (RE.test(valueToValidate));

Answer 1

javascript 中的文字正则表达式应该用 / 围绕模式定义

var RE = /^-{0,1}\d*\.{0,1}\d+$/; //validates decimal format such as 1000.50
if (locale == "fr") {
    RE = /\d+(?:,\d{1,2})?/ //this line fails when validated using the javascript below
}
return (RE.test(valueToValidate));
