Javascript onClick 的 2 个函数只运行最后一个

Question

I have a problem using AJAX. The 2 functions that are called via the onclick event, post each value toggle AJAX and back data in two divs. If only put one function in one onclick. it runs well. but put 2, only run the last one ajax2('".$data."','".$num2."'); . Where is the problem?

echo "<a OnClick=\"ajax1('".$data."','".$num1."');ajax2('".$data."','".$num2."');\">" click </a>";

two js code, function is similar. just function number, processing page and ruturn div is not same.

function1

function ajax1(data,number) {
      HttPRequest = false;
      if (window.XMLHttpRequest) {
         HttPRequest = new XMLHttpRequest();
         if (HttPRequest.overrideMimeType) {
            HttPRequest.overrideMimeType('text/html');
         }
      } else if (window.ActiveXObject) {
         try {
            HttPRequest = new ActiveXObject("Msxml2.XMLHTTP");
         } catch (e) {
            try {
               HttPRequest = new ActiveXObject("Microsoft.XMLHTTP");
            } catch (e) {}
         }
      } 
      }
        var url = 'page1.php';
        var pmeters = "data=" + data + "&number=" + number;
        HttPRequest.open('POST',url,true);
        HttPRequest.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
        HttPRequest.send(pmeters);
        HttPRequest.onreadystatechange = function()
        {
             if(HttPRequest.readyState == 4) 
              {
               document.getElementById("return1").innerHTML = HttPRequest.responseText;                 
              }
        }
   }

function2

function ajax2(data,number) {
      HttPRequest = false;
      if (window.XMLHttpRequest) {
         HttPRequest = new XMLHttpRequest();
         if (HttPRequest.overrideMimeType) {
            HttPRequest.overrideMimeType('text/html');
         }
      } else if (window.ActiveXObject) {
         try {
            HttPRequest = new ActiveXObject("Msxml2.XMLHTTP");
         } catch (e) {
            try {
               HttPRequest = new ActiveXObject("Microsoft.XMLHTTP");
            } catch (e) {}
         }
      } 
      }
        var url = 'page2.php';
        var pmeters = "data=" + data + "&number=" + number;
        HttPRequest.open('POST',url,true);
        HttPRequest.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
        HttPRequest.send(pmeters);
        HttPRequest.onreadystatechange = function()
        {
             if(HttPRequest.readyState == 4) 
              {
               document.getElementById("return2").innerHTML = HttPRequest.responseText;                 
              }
        }
   }

Answer 1

Change the first line of both functions to var HttPRequest = false; . This makes the httprequest private to each function.
