使用JavaScript进行印度货币验证的正则表达式 [英] Regular expression for Indian Currency validation using JavaScript

问题描述

有人可以告诉我如何使用正则表达式检查文本框中输入的金额（印度货币）是否有效？

Can anyone please tell me how to check whether the entered amount (Indian currency) in a textbox is valid or not using regular expression?

我的条件很少。 。

1. 金额不应超过1个小数点，但可以只有一个小数点。


2. 如果有小数点，则后面应跟一个或多个数字。


3. 金额应该只有数字，最多只能有一个小数点。


4. 如果我输入类似10.000的金额，则不应接受它，因为它在小数点后有3个连续的零。但是应该接受56.8906。


5. 如果金额从零开始（即0123），则不应接受，但应接受0.0

1. The amount should not contain more than 1 decimal point, but can have a single decimal point.
2. If there is a decimal point then it should be followed by one or more digits.
3. The amount should have only numbers and at most one decimal point.
4. If I enter an amount like 10.000 then it should not be accepted because it has 3 continuous zeros after decimal point. but 56.8906 should be accepted.
5. If the amount starts with zero (ie 0123) it should not be accepted, but 0.0 should be accepted

推荐答案

^(?:0|[1-9]\d*)(?:\.(?!.*000)\d+)?$

应该做你想做的事。

说明：

^         # Start of string.
(?:       # Try to match...
 0        # either a 0
|         # or
[1-9]\d*  # an integer number > 0, no leading 0 allowed.
)         # End of integer part.
(?:       # Try to match...
 \.       # a decimal point.
 (?!      # Assert that it's not possible to match
  .*000   # any string that contains 000 from this point onwards.
 )        # End of lookahead assertion.
 \d+      # Match one or more digits.
)?        # End of the (optional) decimal part
$         # End of string.

在JavaScript中：

In JavaScript:

curRegExp = /^(?:0|[1-9]\d*)(?:\.(?!.*000)\d+)?$/;
