Menu
I'm developing a PhoneGap application with jQuery Mobile 1.3.1 & jQuery JavaScript Library v1.9.1. I have a login form with a username and a password. There is a JSON api which can send and receive JSON data for processing the login.
I use the following JavaScript for the ajax login.
$('#submit').bind('click', function(e) {
e.preventDefault();
$.ajax({
type : "POST",
url : "http://domainx/public/login",
xhrFields : {withCredentials: true},
crossDomain: true,
beforeSend : function() {$.mobile.showPageLoadingMsg();},
complete : function() {$.mobile.hidePageLoadingMsg();},
data : {username : 'subin', password : 'passwordx'},
dataType : 'json',
success : function(response) {
console.error(JSON.stringify(response));
},
error : function() {
console.error("error");
}
});
});
Here is my html code for the login form.
<div data-role="content">
<form id="login-form" data-ajax="false" method="post">
<fieldset>
<input type="text" name="username" id="username" value="subin" placeholder="Username">
<input type="password" name="password" id="password" value="passwordx" placeholder="Password">
<input type="button" data-theme="b" name="submit" id="submit" value="Enter" data-icon="plus">
</fieldset>
</form>
</div>
But this just don't work. The server returns login failure error, although it works fine for other apps.

You have several error is your code:
Change date to data
data : {username : 'subin', password : 'passwordx'},
Remove this line, it will prevent Phonegap from successful posting:
xhrFields : {withCredentials: true},
In your beforeSend and complete use this function to show loader:
$.mobile.loading('show');
and
$.mobile.loading('hide');
your current ones are deprecated in jQuery 1.2+.
Your final code should look like this:
$.ajax({
type : "POST",
url : "http://domain/public/login",
crossDomain: true,
beforeSend : function() {$.mobile.loading('show')},
complete : function() {$.mobile.loading('hide')},
data : {username : 'subin', password : 'passwordx'},
dataType : 'json',
success : function(response) {
//console.error(JSON.stringify(response));
alert('Works!');
},
error : function() {
//console.error("error");
alert('Now working!');
}
});
Proof that it is working, just run it from the disk and not from a server because you will get a CROSS domain error:

You have a type here:
date : {username : 'subin', password : 'passwordx'},
//--^^^^----this should be named data
try changing to this:
data : {username : 'subin', password : 'passwordx'},
