I want to create asynchronous username validation, where upon change of the value of the username input, the database is accessed to see if that username is valid for use. So far I have this code, which doesn t seem to work. Please help me in finding out where things went wrong. Thanks!
我的超文本:
<div>Username</div>
<input type="text" name="id" id="id">
<div id="idval"></div>
我的文体:
<script>
function CheckId() {
$.get( /signup/ , {username: $(this).val()},
function(data){
if(data == "True"){
$( #idval ).html("You may use this ID");
} else {
$( #idval ).html("Unavailable");
}
});
}
function onChange(){
$("#id").change( function() {CheckId()});
}
$(document).ready(onChange);
</script>
我的看法:
def signup(request):
if request.method == "GET":
p = request.GET.copy()
if p.has_key( username ):
name = p[ username ]
if User.objects.filter(username__iexact=name):
return HttpResponse(False)
else:
return HttpResponse(True)
