sorry for stupid question, but my head is not working anymore today and I have to finish this soon.
I have button to call AJAX:
<button onclick="showUser(this.value)" value="' . $row2["xxx"] . '">' . $row2["xxx"] . '</button>`
and function:
<script>
function showUser(str) {
if (str=="") {
document.getElementById("txtHint").innerHTML="";
return;
}
if (window.XMLHttpRequest) {
// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
} else {
// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function() {
if (this.readyState==4 && this.status==200) {
document.getElementById("maintext").innerHTML=this.responseText;
}
}
xmlhttp.open("GET","maintext.php?q=" +str,true);
xmlhttp.send();
}
</script>
so far so good. if I want to use this function with variable from php, how? Or I could write new function with the same purpose, but where to put variable? I tried:
if (isset($_GET['info'])) {
echo '<script> function showUser(' . $_GET["info"] . ') </script>';
}
...but it doesn`t work.
Thanks for help
You are re-defining the function. You just have to call it after (!) you defined it.
Replace
if (isset($_GET['info'])) {
echo '<script> function showUser(' . $_GET["info"] . ') </script>';
}
with
if (isset($_GET['info'])) {
echo '<script> showUser("' . $_GET["info"] . '") </script>';
}
Additionally you have to insert quotes ( " "
) or Javascript won't take the input as a string.
