客户端的Residentail Address字段验证的JavaScript过滤器 [英] JavaScript Filter for Residentail Address field validation on client side

问题描述

我想在他只能输入的限制范围内验证用户的住址。

字母，数字，冒号，连字符，正斜杠和全数停止。如果他进入该领域的任何其他东西，那么它将给出错误。

请参阅我使用此代码





var address = document.getElementById（address）; //文本区域的ID

var errAddress = document.getElementById（errAddress）; //我希望显示错误的跨度的ID。



var addressFilter = / ^ \w + $ /;

var test_bool_Address = true;

I want to validate the user's residential address within the constraints that he can enter only
alphabets, numbers,Colon,hyphen,forward slash and fulls- stop only. and if he enters any thing else in this field so it will give error.
See I am using this code


var address=document.getElementById("address"); //id of text area
var errAddress=document.getElementById("errAddress"); //id of span where I want to show error.

var addressFilter= /^\w+$/;
var test_bool_Address= true;

if(address.value=="" || address.length >500)
    {
        errAddress.innerHTML='Invalid address!';
        address.focus();
        return false;
    }
    else
    {
         test_bool_Address = filter.test(address.value);

        if(!test_bool_Address){
            errAddress.innerHTML='Invalid address!';
            errAddress.focus();
            return false;
        }
        else
        {
            errAddress.innerHTML='';
        }
    }

推荐答案

/;

var test_bool_Address = true;

/;
var test_bool_Address= true;

if(address.value=="" || address.length >500)
    {
        errAddress.innerHTML='Invalid address!';
        address.focus();
        return false;
    }
    else
    {
         test_bool_Address = filter.test(address.value);

        if(!test_bool_Address){
            errAddress.innerHTML='Invalid address!';
            errAddress.focus();
            return false;
        }
        else
        {
            errAddress.innerHTML='';
        }
    }
