常用的正则表达式总结,见regex.js

验证数字

    var reg = /^[0-9]*$/;<br>
    var texts = "12132";<br>
    if(reg.test(texts)){
      console.log("验证数字");
    }

贴几个自己常用到的(拿来即用)

  1. /^(\d+)(\.?)(\d{0,2})$/ // 输入整数或小数,保留2位小数
  2. /^[0-9.%]{1,}$/ // 输入百分数值
  3. /^1[34578]\d{9}$/ // 验证为手机号码
  4. /^(\/)[\/a-zA-Z0-9_-]+$/ // 以/开头的包含 / 数字字母 _ -
  5. /^[A-Za-z0-9]+$/ // 只能输入数字和字母
