使用ng-pattern的正则表达式仅用于数字(无空格或特殊字符) [英] Regex for numbers only (no spaces or special chars) using ng-pattern

问题描述

我有一个输入字段，仅当它只包含数字，没有特殊字符且没有空格时才有效.我在Angular中使用ng-pattern来验证输入.

I have an input field that should only be valid if it contains only digits and no special characters and no spaces. I am using ng-pattern in angular to validate the input.

我尝试使用:

/^\d+$/

/^\d*$/

/^[0-9]+$/

这些操作可防止出现特殊字符和字母，但对空格不执行任何操作.有谁知道将空格视为无效字符的正则表达式?我试图避免阻止使用keyCode进行输入.

These work to prevent special characters and letters, but do nothing about the spaces. Does anyone know a regex that would consider spaces an invalid character? I am trying to avoid preventing the input using keyCode.

很抱歉是否已经有这个话题.我发现了很多类似的东西，但是没有任何帮助.

I apologize if there's already a thread for this. I found many similar ones but nothing that helped with the spaces.

即使正则表达式被认为可以正常防止空格，它似乎也无法与ng-pattern一起使用:

Even if the regex is supposed to prevent spaces normally, it is does not seem to be working with ng-pattern:

<input type="tel" maxlength="10" ng-pattern="/^[0-9]+$/" placeholder="(1234567890)" />

如果我输入空格，仍在输入上返回 ng-valid-pattern 类.

Is still returning the ng-valid-pattern class on the input if I type a space.

推荐答案

此模式应起作用:/^ \ d + $/

This pattern should work: /^\d+$/
