逗号分隔十进制的Javascript正则表达式

Question

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

即。 '1000'，'1000,0'和'1000,00'

但我需要使用javascript工作：

 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));

只是语法检查：你是否忘记了第二次作业中的正斜杠？
