检查文本字段的正则表达式代码正在工作，直到给出“输入” [英] Regex code to check textfield is working until a 'enter' is given

问题描述

我们在检查文本字段时遇到麻烦。我们在这里尝试做的是检查默认文本是否已更改。如果不是这样，那么表单末尾会出现一个警告。



一切正常，直到文本字段包含'return'（回车）在文中。即使默认文本消失，输入也将导致正则表达式代码失败..



这里使用的代码：



^（（？！\ b这包含默认文字）。）* $



请告诉我，如果你可以帮我在这里



我尝试过：



几个代码......对不起，我已经没有了。我们还用验证器检查了代码。

Hi, we are having troubles whit checking a textfield. What we try to do here is to check if the default text has changed. If that is not the case, then a warning will appear at the end of the form.

Everything is working fine until a textfield contains a 'return' (enter) in the text. Even when the default text is gone, the enter will be responsible for the regex-code to fail..

Here the code i have used:

^((?!\bThis contains the default text).)*$

Pleas let me know if you can help me out here

What I have tried:

several codes... Sorry, i don't have them anymore. We also checked the code with a validator.
