Angular-Xeditable e-pattern not accepting valid regular expression

Question

I am trying to validate the user input of a text field using e-pattern from the angular-xeditable directive. I have built the regular expression using an online regex builder/tester and it does exactly what I want however angular-xeditable doesn't seem to recognize the expression as being valid. It shows the below even when the expression is valid.

requirements:

• Value must be >= 0.0 or <= 1.0
• Value can have one or two decimal places
• First decimal place can be a digit between 0-9
• Second decimal place should be either 0 or 5

valid entry: 0.5, 0.95, 0.40, 1.0

regex:

 ^((0+(\.[0-9][05]?))|1+(\.0))$

code:

<span e-pattern="/^((0+(\\.[0-9][05]?))|1+(\\.0))$/" e-required ng-show="!tableform.$visible" editable-text="user.available" e-form="tableform" onbeforesave="checkAvailable($data)">{{ user.available}} </span>

message:

Is there anything I'm missing or need to amend to the expression or span tag?

Answer 1

失败了，我只是想出了一个问题，它非常简单的电子模式在表达式之前或之后不需要/ ^或$ /，应改为：

 e-pattern="((0+(\.[0-9][05]?))|1+(\.0))"
