New to JSON/AJAX here but trying...
PHP page appears to be returning [{"id":"1"},{"id":2}] to my javascript. How would I convert it to something useful like a dropdown in html?
Code:
<script>
function show(str) {
if (str=="") {
var ajaxDisplay=xmlhttp.responseText;
var res=ajaxDisplay.split("#");
document.getElementById("ajax1").innerHTML=res[1];
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) {
var ajaxDisplay=xmlhttp.responseText;
var res=ajaxDisplay.split("#");
document.getElementById("ajax1").innerHTML=res[0];
}
}
xmlhttp.open("GET","get.php?q="+str,true);
xmlhttp.send();
}
</script>
<div id='ajax1'><b>ID dropdown will be listed here.</b></div>
