serialization

问题 I am using $(this).serialize() when submitting a form. It works well, except in times when I (for some reason) have 2 fields with same name (one visible, and one not, and I am not talking about type="visible" but display:none )... But of course serialize has no regard for this... it just takes them all. I tried this var $disabled_list = $(this).find('input:hidden,select:hidden,textarea:hidden').attr('disabled', 'disabled'); $(this).serialize(); $disabled_list.attr('disabled',''); and It is

问题 Just like the way we save the instance variables using serialization, is there any way by which I can save the state of static members? If there is a situation, where getting back the state of static members is necessary to restore something, how would one do that? 回答1: The easiest option that comes to my mind is to use a singleton rather than static fields. The singleton object can be serialized and deserialized, and you can manage its lifetime, while you preserve the 'global state' that

问题 I'm planning to build a WCFservice that returns generic dictionary objects serialized to JSON. Unfortunately, serialization fails, as object is potentially always different. KnownTypes can't help, because property type is Dictionary, and I can't say KnownType, as the class will potentially be always different. Any ideas if it's possible to serialize an 'unknown type'? I don't mind to specify DataContract/DataMember for each of my classes, but (at least for prototype version) I don't want to

问题 I have a form on my site like this: <form id="myform" action="" method=""> <input type="text" name="name[1][first]"> <input type="text" name="name[2][first]"> <input type="text" name="name[3][first]"> </form> I want to simply grab all the data and send it to a webservice so have this js: $fields = $('#myform').serializeArray(); Problem is, it creates the json with all the brackets shown in the input names so I get a parse error. How can I use serializeArray and get proper json? The resulting

问题 If you want to make CLOS objects in common lisp printable (print readably), how do you go about doing this without using anything but print and read. 回答1: There are two parts to doing this, at least in my solution, however you will need this function (thanks to the guys at cl-prevalence for this ( warn LLGPL ) (defun get-slots (object) ;; thanks to cl-prevalence #+openmcl (mapcar #'ccl:slot-definition-name (#-openmcl-native-threads ccl:class-instance-slots #+openmcl-native-threads ccl:class

问题 I'm looking through some existing code in a project I'm working on, and I found a class that is implemented as: public class ThingOne { private int A; private int B; [NonSerialized] private System.Timers.Timer timer1; } Shouldn't it look more like this? [Serializable] public class ThingOne { private int A; private int B; [NonSerialized] private System.Timers.Timer timer1; } Or is there some additional benefit to adding [NonSerialized] even when the class itself is not Serializable? 回答1:

问题 I have a javascript file serializing and sending a form to the php function: function call_ajax(){ var data2 = jQuery('#newIdeaForm').serialize(); // <--- Important jQuery.ajax({ type: 'POST', url: myAjax.ajaxurl, data: ({action : 'savedata',data : data2}), success: function() { alert(data2); } }); }; The thing is that I don't know how to receive this form in this php function: function savedata(){ $my_post = array( 'post_title' => 'data.name', 'post_content' => 'data.idea', 'post_status' =>

问题 I want to parse to JSON this: Map<Pair<String, Date>, Product> Since JSON cannot have a Pair has key it obviously gives me something like this: {"android.util.Pair@a24f8432":{"Name:"name","Brand":"brand"....}} At this point to achieve my goal I'll have to create my Pair<String, Date> Object Serialize and Deserialize methods. This is where I need your help, I have no idea how to do this. Do I have to create MyPair class extending Pair and implementing JsonSerializer<Pair<String, Date>> ...?

问题 I'm serializing an object graph in the android code and pass result to GAE servlet. While deserializing I sometimes get the following exception: java.io.StreamCorruptedException: invalid type code: 71 I traced the problem down to one of the fields. If I set it to null or mark as transient the problem disappears. But, if I serialize/deserialize only this field - I don't see any problems as well. Any ideas? 回答1: I suggest to use JSON or Google Protocol Buffers instead of own serialization code.
