當我在選擇onchange事件中選擇ALL時,while循環未執行。當我選擇全部時如何顯示所有記錄
dropdown.php
<script>
function showUser(str)
{
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","getuser.php?q="+str,true);
xmlhttp.send();
}
</script>
<?php
$mysqli = new mysqli("localhost", "root", "", "app");

我身體設置爲showuser(STR = 「ALL」),但就像在圖片時,我選擇所有的while循環ISN不執行。問題是什麼?
太棒了!謝謝:)另外一件事。當鼠標懸停時,我的表格有一個腳本,排序和行的顏色。但這不起作用。我認爲我的腳本在上面影響其他腳本getuser.php –
