我假设您正在寻找类似的东西:

I assume you looking for something like that:

$('#login-form').ajaxForm({  
    success: function( data) { 
    $("#panel").html( data);//Will insert new content inside div element.
    } 
});

FIX:

$('#login-form').ajaxForm({ 
    target: '#panel', //Will update the "#panel"
    success: function( data) { 
    alert( "Success");
    } 
});
