[英]regular expresstion to match [/ , .] in ng-pattern
I am trying to create a expression so that input string must not contain forward slash, comma or a dot. 我正在尝试创建一个表达式,以便输入字符串不得包含正斜杠,逗号或点。
<form name="myForm">
<div class="col-sm-4">
<input class="form-control"
type="text"
data-ng-model="model_name"
name="modelName"
ng-pattern="/^[\/,.]/" required>
<div ng-messages="myForm.$submitted && myForm.modelName.$error" role="alert">
<div class="alert alert-danger" ng-message="pattern">Special characters [/ , .] are not allowed.</div>
<div class="alert alert-danger" ng-message="required">This field is required.</div>
</div>
</div>
</form>
The regular expression /^[\\/,.]/
properly matches all the characters inside the square brackets but the problem is that it is not allowing me to input normal strings such as abc or abc_def or any other strings. 正则表达式
/^[\\/,.]/
正确匹配方括号内的所有字符,但是问题在于它不允许我输入普通字符串,例如abc或abc_def或任何其他字符串。 I don't have deep knowledge of regex and I am not getting any idea how to solve this problem. 我对正则表达式没有很深的了解,我也不知道如何解决此问题。 Please help.
请帮忙。
Your regex
is wrong, ^
must be inside []
in order to match all characters except /.,
put them in a [^/.,]
, in regex, when using ^
inside a block []
will match anything but what is inside the []
. 您的
regex
是错误的, ^
必须位于[]
内才能匹配/.,
以外的所有字符/.,
将它们放在regex中的[^/.,]
中,当在块中使用^
时, []
会匹配除内部内容以外的任何字符[]
。
