Question

我正在使用ajax。我必须使用ajax在名为index.php的另一个页面内调用名为chart.php的页面。当我运行index.php时，不会调用chart.php文件而不能正常工作。但如果我只运行chart.php，它的工作原理。所以我认为编码是完美的..但我仍然无法找到错误

的index.php

    <head>

<script>
function selectMonth(str) { 
  if (str=="") {
    document.getElementById("month").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("month").innerHTML =xmlhttp.responseText;
    }
  }
  xmlhttp.open("GET","chart.php?q="+str,true);
  xmlhttp.send();
}
</script>
</head>


<body>
       <div class="col-lg-3">
                <select class="form-control" name="month"  onChange="selectMonth(this.value)">
