JS: regex for numbers and spaces?
提问by matt
I'm using happyJSand use the regex underneath for phone validation
我正在使用happyJS并使用下面的正则表达式进行电话验证
phone: function (val) {
return /^(?:[0-9]+$)/.test(val);
}
However this ONLY allows numbers. I want the user to be able to enter spaces as well like
但是，这仅允许数字。我希望用户也能够输入空格
238 238 45383
Any idea why return /^(?:[0-9 ]+$)/.test(val);is not doing the trick?
知道为什么return /^(?:[0-9 ]+$)/.test(val);不这样做吗？

This is my suggested solution:
这是我建议的解决方案：
/^(?=.*\d)[\d ]+$/.test(val)
The (?=.*\d)asserts that there is at least one digit in the input. Otherwise, an input with only blank spaces can match.
该(?=.*\d)断言有在输入的至少一个数字。否则，只有空格的输入才能匹配。
Note that this doesn't put any constraint on the number of digits (only makes sure there are at least 1 digit), or where the space should appear in the input.
请注意，这不会对位数（仅确保至少有 1 位数）或空格应出现在输入中的位置施加任何限制。

Try
尝试
phone: function (val) {
return /^(\s*[0-9]+\s*)+$/.test(val);
}
At least one number must be present for the above to succeed but please have a look at the regex example here

Try
尝试
/^[\d ]*$/.test("238 238 45383")
console.log(/^[\d ]*$/.test("238 238 45383"));回答by amit pandya
You can try the below regex for checking numbers and spaces.
您可以尝试使用以下正则表达式来检查数字和空格。
function isTextAndNumberSpaceOnly(text) {
var regex = /^[0-9 ]+$/;
if (regex.test(text)) {
return true;
} else {
return false;
}
}

Personally I use this code and it works properly:
我个人使用此代码并且它可以正常工作：
function validateMobile(mob)
{
var re = /^09[0-9]{9}$/
if(mob.match(re))
return true;
else
return false;
}
