Hello experts,
I cannot findout how I can write to global variables in a a JQUERY function.
In the following script code you will understand my problem.
I appreciate your help.
<script type="text/javascript">
function checkusername (username ) {
$.post("http://example.com/index.php", {action: 5, username: username }, function(xml) {
result = $("apot", xml).text(); //<-- this variable is not global... why ??
message = $("message", xml).text(); //<-- this variable is not global... why ??
alert(message); //<--here variables are shown ok
alert(result);
});
alert(message); //<--here variable is NULL !!
alert(result); //<--here variable is NULL !!
}
</sctipt>
