Question

我试图让txtHint每次通过时都是唯一的或不同的。任何有关创建计数器或增量的帮助都将非常感激。感谢

  <script type="text/javascript">
  function showCustomer(str)
  {
      var xmlhttp;    
      if (str=="")
      {
           document.getElementById("txtHint").innerHTML="";
           return;
      }
      if (window.XMLHttpRequest)
      {
           // code for IE7+, Firefox, Chrome, Opera, Safari
           xmlhttp=new XMLHttpRequest();
      }
      else
      {
           // code for IE6, IE5
           xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
      }
      xmlhttp.onreadystatechange=function()
      {
           if (xmlhttp.readyState==4 && xmlhttp.status==200)
           {
                document.getElementById("txtHint").innerHTML=xmlhttp.responseText;
           }
      }
      xmlhttp.open("GET","***.php?q="+str,true);
      xmlhttp.send();
 }
 </script>

Answer 1

<script type="text/javascript">
    var count = 0;
    function showCustomer(str) {
        count++;

然后将"txtHint"替换为"txtHint" + count

创建唯一的getElement ID
