javascript - jQuery $.post-function | data-processing function does not work -

-

i new in web development, having years of experience in traditional development, e.g. using java, c , abap, under belt.

i trying create pretty simple login-functionality, struggling jquery's $.post()-functionality.

in below seen code, alert("test")-function in data-processing part of $.post() doesn´t seem executed, after submit form form_login. guess problem how connected javascript-function login_attempt() submitting of form form_login.

<!doctype html>  <html>  <head>  	<title>login</title>    	<script src="jquery-2.2.4.min.js"></script>    	<script>  	function login_attempt(){  		$.post("login.php", $("#form_login").serialize(), function(data){alert("test");},html);  	}  	</script>    </head>  <body>  	<h1>login-form</h1>	  	<form id="form_login" method="post" onsubmit="return login_attempt()">  		<p><label for="id_username">username: </label><input id="id_username" name="username" type="text" width="20"></label></p>  		<p><label for="id_password">password: </label><input id="id_password" name="password" type="password" width="10"></label></p>  		<p><input type="submit" name="submit_login"></p>  	</form>    		  </body>  </html>

the function login_attempt triggered when submitting form , after form submitted since login_attempt function not tell form stop submitting in regular way. therefor page reloads before actual callback of post method anything.

add return false; last line of login_attempt function tell form should not submit in regular way.

this error has shown on many times, seems. prominent answer issue seems restkit 0.20 — coredata: error: failed call designated initializer on nsmanagedobject class however, solution posted doesn't work me. let's start beginning: i want upload file server. want parse response make sure uploaded. if not, try again later. model has boolean variable called nsnumber *senttoserver purpose (in coredata, bool saved nsnumber ) . because don't know whether sending going successful, save entity coredata model first before sending via restkit. when post request successful, server returns json string this: {"id":14,"created":true} notice that, of course, id not set on coredata model yet, both id , created new informations model. here's model: @interface recording : nsmanagedobject @property (nonatomic, retain) nsstring * audiofilepath; @property (nonatomic, retain) nsdate * createdat; @property (nonatomic, retain) nsstring * deviceid; @
