如何在javascript中验证接受数字和字母但不应该只接受数字和特殊字符“/” [英] how to validate in javascript to accept numbers and alphabets but should not accept only numbers and special character "/"

问题描述

如何在javascript中验证接受数字和字母但不应仅接受数字和特殊字符/示例：它可以是12/90，annanagar但它不应该是12 /或 12..任何人都可以帮助我在javascript中执行此操作





我试过的代码：

< pre lang =cs> var addresspat = / ^（ @ [^ \d\ /]）$ /;
var address = document.getElementById（ <％= txtAddr.ClientID％>）。 value ;
var matchArray = address.match（addresspat）;
if （matchArray == null ）
{
}
else {
alert（ 输入正确的地址）;
document.getElementById（ <％= txtAddr.ClientID％>）。焦点（）;
return false ;
}

解决方案

/;
var address = document.getElementById（ <％= txtAddr.ClientID％>）。 value ;
var matchArray = address.match（addresspat）;
if （matchArray == null ）
{
}
else {
alert（ 输入正确的地址）;
document.getElementById（ <％= txtAddr.ClientID％>）。焦点（）;
return false ;
}

你好Nityasri，



你的地址是非常重要的必须从数字开始，然后是斜线，然后是数字？如果是，请尝试使用

  var  PAT_CHECK = /(\d+\/\d+).*/g 
  var  ret = val.match（PAT_CHECK）; 
  if （ret ==  null ）
 alert（ 地址无效！）; 

问候，

Hello Nityasri,

Is it very much essentials that your address must start with numbers followed by a slash then numbers? If so then try with

var PAT_CHECK = /(\d+\/\d+).*/g
var ret = val.match(PAT_CHECK);
if (ret == null)
    alert("Invalid address!");
