本指南提供了可使用jQuery的.match()
函數可用的常見正則表達式(REGEXP)選擇器。 這對於在網頁中定位特定文本並根據這些發現或表單驗證實施操作是無價的。
數字的jQuery正則表達式:
// Select integers only var intRegex = /[0-9 -()+]+$/; // Match any IP address var ipRegex = /\b(?:\d{1,3}\.){3}\d{1,3}\b/; // Match number in range 0-255 var num0to255Regex = /^([01][0-9][0-9]|2[0-4][0-9]|25[0-5])$/; // Match number in range 0-999 var num0to999Regex = /^([0-9]|[1-9][0-9]|[1-9][0-9][0-9])$/; // Match integers and floating-point numbers/decimals var floatRegex = /[-+]?([0-9]*\.[0-9]+|[0-9]+)/; // Match any number from 1 to 50 inclusive var number1to50Regex = /(^[1-9]{1}$|^[1-4]{1}[0-9]{1}$|^50$)/gm;
jQuery驗證的正則表達式:
// Match email address var emailRegex = /^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$/; // Match credit card numbers (Note: This is a simplified example and may not cover all valid credit card formats) var creditCardRegex = /^(?:4[0-9]{12}(?:[0-9]{3})?|5[1-5][0-9]{14}|6(?:011|5[0-9][0-9])[0-9]{12}|3[47][0-9]{13}|3(?:0[0-5]|[68][0-9])[0-9]{11}|(?:2131|1800|35\d{3})\d{11})$/; // Match username var usernameRegex = /^[a-z0-9_-]{3,16}$/; // Match password var passwordRegex = /^[a-z0-9_-]{6,18}$/; // Match 8 to 15 character string with at least one uppercase letter, one lowercase letter, and one digit (useful for passwords) var passwordStrengthRegex = /((?=.*\d)(?=.*[a-z])(?=.*[A-Z]).{8,15})/gm; // Match elements that could contain a phone number var phoneNumber = /[0-9-()+]{3,20}/;
> URL的
> jQuery的正則表達式:// Match date (e.g., 21/3/2006) var dateRegex = /(\d{1,2}\/\d{1,2}\/\d{4})/gm; // Match date in MM/DD/YYYY format var dateMMDDYYYRegex = /^(0[1-9]|1[012])[- \/.](0[1-9]|[12][0-9]|3[01])[- \/.](19|20)\d\d$/; // Match date in DD/MM/YYYY format var dateDDMMYYYRegex = /^(0[1-9]|[12][0-9]|3[01])[- \/.](0[1-9]|1[012])[- \/.](19|20)\d\d$/;
>
元音,空格,域名,圖像和其他有用的示例的jQuery正則表達式:// Match a URL var urlRegex = /^(https?:\/\/)?([\da-z.-]+)\.([a-z.]{2,6})([\/\w .-]*)*\/?$/; // Match a URL slug (letters/numbers/hyphens) var urlslugRegex = /^[a-z0-9-]+$/; // Match a URL string (handles spaces and query strings) var urlRegex = /(https?:\/\/)?([\da-z.-]+)\.([a-z.]{2,6})([\/\w.-=?]*)*\/?/;
