来电和来电是两个文本字段输入电话号码，他们有以下验证。

号码丢失

标签必须只包含数字和最大字段长度18

不能是1212121212或1234567890

不能拥有所有相同的数字

不能与调用相同的价值



如果C​​alling To：验证失败，当用户选择完成后，将显示以下错误消息：



无效拨打电话号码。

拨打号码：

- 长度必须为10到18个字符且仅限数字。

- 不能与呼叫来源相同。

- 不能包含所有相同的数字（例如7777777777）。

calling to and calling from are two text fields to enter phone numbers and they have following validations.
Number is missing
tag must contain only numbers and a maximum field length of 18
cannot be 1212121212 or 1234567890
cannot have all the same digits
cannot be the same value as Calling From

"If the Calling To: validation fails the following error message will be shown when the user chooses done:

"Invalid Calling to phone number.
The Calling To Number:
- Must be 10 to 18 characters in length and numeric only.
- Cannot be the same value as the Calling From.
- Cannot consist of all the same numbers (for example 7777777777).
- Cannot have a format like 1212121212 or 1234567890."

It would be really helpful if someone could help me out on this code.

推荐答案

您可以使用substr和indexOf将数字视为一个字符串，只需几个循环即可获得解决方案。另一种选择只是使用正则表达式。从网上获取一个并改变它。



我假设不允许JQuery。



在发布您的代码之前，您不会得到编码答案。

You could use substr and indexOf to treat the numbers as a string and with a few loops you''ll have your solution. The other option is simply to use a regular expression. Get one from the web and alter it.

I''m assuming JQuery is not allowed.

You won''t get a coded answer until you post the code you have.

使用SubString，Length函数。

Use SubString, Length functions.
