Javascript check of a form, not waiting for ajax response
- by Y.G.J
this is a part of the check in my form
function check(theform) {
var re = /^\w[0-9A-Za-z]{5,19}$/;
if (!re.test(theform.username.value)) {
alert("not valid username");
theform.username.focus();
return false;
}
$.ajax({
type: "POST",
url: "username.asp",
data: "username="+theform.username.value,
success: function(msg){
username = msg;
if (!username) {
alert("username already in use");
return false;
}
}
});
var re = /^\w[0-9A-Za-z]{5,19}$/;
if (!re.test(theform.password.value)) {
alert("not valid password");
theform.password.focus();
return false;
}
}
for some reason of sync... it check the username then duplicated username with the ajax and not waiting for respond and jump to the password check.
i don't want to insert the rest of the code to isreadystate (or what ever it is) because i might move the username duplicate check to the end... and then the function will end before the ajax anyway
what should i do?
