正则表达式验证以包含带有jquery的enter键

i am using the jQuery.validationEngine i need to mod one property so that i can use it with a text area

rite now the regex is

"onlyNumberSp": {
                    "regex": /^[0-9\ ]+$/,
                    "alertText": "* Numbers only"

it allows numbers only and a space, i need to take out the space and include a return key.

Change your regular expression to disallow spaces and allow newlines:

"regex": /^[0-9
]+$/
