Question

我需要能够输入以下任何类型的信息到一个文本字段。

客户名称（即名字和姓氏）。
客户电话号码。（包括区号）
客户电子邮件地址。
客户服务票号。
客户产品序列号。

到目前为止它的工作原理是我有5个不同的PHP文件每种类型的信息都要输入一个。

如果我不断更改函数requestCustomerInfo（），这适用于每个。

我正在使用Ajax XHR请求 - 下面的工作示例：这是在 index.php 页面中。

function handleHttpResponse() {    
    if (http.readyState == 4) { 
      if(http.status==200) { 
         var results=http.responseText; 
         document.getElementById('divCustomerInfo').innerHTML = results; 
      } 
    } 
}



function requestCustomerInfo() {      

   //look up info by customer name
   var url = "GetCustomerName.php?name="; // The server-side script
   var sName = document.getElementById("CustomerId").value; 
   http.open("GET", url + escape(sName),  true);  


   //look up info by customer email 
   //var url = "GetCustomerEmail.php?email="; // The server-side script 
   //var sEmail = document.getElementById("CustomerId").value;
   //http.open("GET", url + escape(sEmail), true);


   //look up info by customer phone number
   //var url = "GetCustomerPhone.php?phone="; // The server-side script
   //var sPhone = document.getElementById("CustomerId").value; 
   //http.open("GET", url + escape(sPhone), true);  


   //look up info by customer product serial number
   //var url = "GetProductSerialNumber.php?serial="; // The server-side script 
   //var sSerial = document.getElementById("CustomerId").value; 
   //http.open("GET", url + escape(sSerial), true);


   //look up info by customer product service ticket number 
   //var url = "GetServiceTicket.php?ticket="; // The server-side script
   //var sTicket = document.getElementById("CustomerId").value;
   //http.open("GET", url + escape(sTicket), true);


    http.onreadystatechange = handleHttpResponse; 
    http.send(null); 
 } 

 function getHTTPObject() { 
    var xmlhttp; 

    if(window.XMLHttpRequest){ 
         xmlhttp = new XMLHttpRequest(); 
    } 
    else if (window.ActiveXObject){ 
         xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); 
         if (!xmlhttp){ 
             xmlhttp=new ActiveXObject("Msxml2.XMLHTTP"); 
         } 
   } 
   return xmlhttp; 
 } 

 var http = getHTTPObject(); // We create the HTTP Object

这是选择用户js文件：用于传递信息以获取用户的选择下拉列表。

// JavaScript Document
var xmlhttp;

function showUser(str)
{
xmlhttp=GetXmlHttpObject();
if (xmlhttp==null)
  {
  alert ("Browser does not support HTTP Request");
  return;
  }
var url="getuser.php";
url=url+"?q="+str;
url=url+"&sid="+Math.random();
xmlhttp.onreadystatechange=stateChanged;
xmlhttp.open("GET",url,true);
xmlhttp.send(null);
}

function stateChanged()
{
if (xmlhttp.readyState==4)
{
document.getElementById("txtHint").innerHTML=xmlhttp.responseText;
}
}

function GetXmlHttpObject()
{
if (window.XMLHttpRequest)
  {
  // code for IE7+, Firefox, Chrome, Opera, Safari
  return new XMLHttpRequest();
  }
if (window.ActiveXObject)
  {
  // code for IE6, IE5
  return new ActiveXObject("Microsoft.XMLHTTP");
  }
return null;
}

这是 getuser js 文件：用于填充生产信息部分。

<?php

//database information 
$sDBServer = "localhost"; 
$sDBName = "customers"; 
$sDBUsername = "root"; 
$sDBPassword = "root";

$q=$_GET["q"];

$con = mysql_connect($sDBServer, $sDBUsername, $sDBPassword);
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db( $sDBName );

$sql="SELECT * FROM serviceTicket WHERE id = '".$q."'";  

//$sql="SELECT * FROM serviceTicket WHERE id = 3";  

$result = mysql_query($sql);

while($row = mysql_fetch_array($result))
  {
  echo '<div class="productInfo">Product Information </div>';

  echo  "Product : " . $row['product'].'<br/>' ;

  echo  "Serial number : " . $row['serial'] .'<br/>';
  echo  "Model number : " . $row['model'].'<br/>' ;

  echo "Computer brand : " . $row['computer'] .'<br/>';
  echo "Operating system  : " . $row['os'].'<br/>';

  echo '<div class="productIssue">Issues and Resolution documents </div>';

  echo "Product issues" .'<br/>'. $row['issue'].'<br/>';

  echo "Knowledge base docs : " . $row['docs'] .'<br/>';
  echo "Customer service order : " . $row['cso'].'<br/>';

  }

mysql_close($con);
?>

以上所有内容都有效，但我希望能够查找一个字段客户信息。

任何帮助将不胜感激。

Answer 1

某种正则表达怎么样？您将测试某个表达式是否为真。

你可以使用很多预先制作的表达方式。

电子邮件你可以谷歌一个，电话号码取决于他们将如何输入。（10位数或xxx-xxx-xxxx）如果它是固定长度的串行，但有数字和字母名字和姓氏将是两个字母或两个字母之间的空格票号也可以是固定长度的号码。

您可以检查并查看它匹配哪一个，然后将其传递给正确的文件。

单个文本字段用于数据库查询
