[Serialize][1] *does* include all enabled `input` elements **with a `name` attribute**.


  [1]: http://docs.jquery.com/Ajax/serialize

Maybe combining the two in a single selector would work?

    $(&quot;:input,:hidden&quot;).serialize();

edit: I just tried the above and it worked. but, $(&quot;form&quot;).serialize(); should automatically take all inputs as others have mentioned.

You need set the name attribute and check the **disabled** attribute! The disabled field also not serialized.

Just ran into this problem myself, and hacked out a solution.

The problem has to do with the way JQuery picks up hidden html information. It will not pick up the TEXT of a hidden field as its value, you must use the value= property.

To set it in JQUERY use `$(field).val(yourvalue);`

you should add name to all elements for serialize function to work properly

I had this problem as well.  Out of habit I close my input fields with /&gt;.  I found that hidden input does not work when closed this way.

    &lt;input type=&quot;hidden&quot; name=&quot;someName&quot; value=&quot;someValue&quot; /&gt; 

 

does not work.

    &lt;input type=&quot;hidden&quot; name=&quot;someName&quot; value=&quot;someValue&quot; &gt;

  

does work.

A long question, please bear with me.

We are using Spring+JPA for a web application. My team is debating over injecting `EntityManagerFactory` in the `GenericDAO` (a DAO based on Generics something on the lines provided by APPFUSE, we do not use `JpaDaosupport` for some reason) over injecting an `EntityManager`. We are using &quot;application managed persistence&quot;.

The arguments against injecting a `EntityManagerFactory` is that its too heavy and so is not required, the `EntityManager` does what we need. Also, as Spring would create a new instance of a DAO for every web request(I doubt this) there are not going to be any concurrency issues as in the same `EntityManager` instance is shared by two threads.

The argument for injecting EFM is that its a good practice over all its always good to have a handle to a factory.

I am not sure which is the best approach, can someone please enlighten me?

Using JQuery animate I would like to operate with css classes, defined somewhere in .css file, not to have to  give all styles params to jquery.animate() explicitly.

I can create a fake (e.g. invisible) element with such a class, read its css properties and give them to jquery.animate()  - does anybody know a better way?

I run serialize on a form, where on of the fields is hidden - and it&#39;s a very important field, which should be posted. Is there any way to easily serialize it through jQuery or should I write my own function?

I would like to move one DIV element inside another. For example, I want to move this (including all children):

    &lt;div id=&quot;source&quot;&gt;
    ...
    &lt;/div&gt;

into this:

    &lt;div id=&quot;destination&quot;&gt;
    ...
    &lt;/div&gt;

so that I have this:

    &lt;div id=&quot;destination&quot;&gt;
      &lt;div id=&quot;source&quot;&gt;
        ...
      &lt;/div&gt;
    &lt;/div&gt;

How to move an element into another element?

I have an select box:

    &lt;select id=&quot;selectBox&quot;&gt;
      &lt;option value=&quot;0&quot;&gt;Number 0&lt;/option&gt;
      &lt;option value=&quot;1&quot;&gt;Number 1&lt;/option&gt;
      &lt;option value=&quot;2&quot;&gt;Number 2&lt;/option&gt;
      &lt;option value=&quot;3&quot;&gt;Number 3&lt;/option&gt;
      &lt;option value=&quot;4&quot;&gt;Number 4&lt;/option&gt;
      &lt;option value=&quot;5&quot;&gt;Number 5&lt;/option&gt;
      &lt;option value=&quot;6&quot;&gt;Number 6&lt;/option&gt;
      &lt;option value=&quot;7&quot;&gt;Number 7&lt;/option&gt;
    &lt;/select&gt;

I&#39;d like to set one of the options as &quot;selected&quot; based on it&#39;s selected index.

For example, if I am trying to set &quot;Number 3&quot;, I&#39;m trying this:

    $(&#39;#selectBox&#39;)[3].attr(&#39;selected&#39;, &#39;selected&#39;);

But this doesn&#39;t work.  How can I set an option as selected based on it&#39;s index using jQuery?

Thanks!

It is quite easy to load HTML content from your custom URLs/Web services using JQuery or any other similar framework. I&#39;ve used this approach many times and till now and found the performance satisfactory.

But all the books, all the experts are trying to get me to use JSON instead of generated HTML. How&#39;s it much more superior than HTML? 

**Is it very much faster?&lt;br /&gt;
Does it have a very much lesser load on the server?**

On the other side I have some reasons for using generated HTML.

1. It&#39;s simple markup, and often just as compact or actually more compact than JSON.
2. It&#39;s less error prone cause all you&#39;re getting is markup, and no code.
3. It will be faster to program in most cases cause you won&#39;t have to write code separately for the client end.

Which side are you on and why?

Why is it a bad practice to return generated HTML instead of JSON? Or is it?

How can I trigger a change event on a [jQuery UI slider](http://docs.jquery.com/UI/Slider)?

I thought it would be 

	$(&#39;#slider&#39;).trigger(&#39;slidechange&#39;);

but that does nothing.

*Full example script follows:*


    &lt;link href=&quot;http://jqueryui.com/latest/themes/base/ui.all.css&quot; rel=&quot;stylesheet&quot; type=&quot;text/css&quot;&gt; 
    
    &lt;script src=&quot;http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.js&quot; type=&quot;text/javascript&quot;&gt;&lt;/script&gt; 
    &lt;script src=&quot;http://jqueryui.com/latest/ui/ui.core.js&quot; type=&quot;text/javascript&quot;&gt;&lt;/script&gt; 
    &lt;script src=&quot;http://jqueryui.com/latest/ui/ui.slider.js&quot; type=&quot;text/javascript&quot;&gt;&lt;/script&gt; 
    
    &lt;body&gt;
    
    &lt;div id=&quot;slider&quot;&gt;&lt;/div&gt;
    
    &lt;script type=&quot;text/javascript&quot;&gt;
    
    $().ready(function()
    {
    	$(&#39;#slider&#39;).slider({change: function() { alert(0); }});
    
    	// These don&#39;t work
    	$(&#39;#slider&#39;).trigger(&#39;change&#39;);
    	$(&#39;#slider&#39;).trigger(&#39;slidechange&#39;);
    });
    &lt;/script&gt;

I would expect this to alert &quot;0&quot; when the page loads

How would I use the JQuery Validate plugin to have one error message for say 3 fields. For example 3 dob fields. By default I will get 3 error messages if all 3 fields are left blank. I only want one error linked to 3 fields. If any are blank the error comes up.

I get an xml from the 3rd party and I need to deserialize it into C# object. This xml may contain attributes with value of integer type or empty value: attr=”11” or attr=””. I want to deserialize this attribute value into the property with type of nullable integer. But XmlSerializer does not support deserialization into nullable types. The following test code fails during creation of XmlSerializer with InvalidOperationException {&quot;There was an error reflecting type &#39;TestConsoleApplication.SerializeMe&#39;.&quot;}.

    [XmlRoot(&quot;root&quot;)]
    public class SerializeMe
    {
        [XmlElement(&quot;element&quot;)]
        public Element Element { get; set; }
    }

    public class Element
    {
        [XmlAttribute(&quot;attr&quot;)]
        public int? Value { get; set; }
    }

    class Program {
        static void Main(string[] args) {
            string xml = &quot;&lt;root&gt;&lt;element attr=&#39;&#39;&gt;valE&lt;/element&gt;&lt;/root&gt;&quot;;
            var deserializer = new XmlSerializer(typeof(SerializeMe));
            Stream xmlStream = new MemoryStream(Encoding.ASCII.GetBytes(xml));
            var result = (SerializeMe)deserializer.Deserialize(xmlStream);
        }
    }

When I change type of &#39;Value&#39; property to int, deserialization fails with InvalidOperationException:

&gt;There is an error in XML document (1, 16).

Can anybody advise how to deserialize attribute with empty value into nullable type (as a null) at the same time deserializing non-empty attribute value into the integer? Is there any trick for this so I will not have to do deserialization of each field manually (actually there are a lot of them)?

Update after comment from ahsteele:

 1. [Xsi:nil attribute][1] 

 As far as I know, this attribute works only with XmlElementAttribute - this attribute specifies that the element has no content, whether child elements or body text. But I need to find the solution for XmlAttributeAttribute. Anyway I cannot change xml because I have no control over it.

 2. [bool *Specified property][2]

 This property works only when attribute value is non-empty or when attribute is missing. When attr has empty value (attr=&#39;&#39;) the XmlSerializer constructor fails (as expected).

        public class Element
        {
    	    [XmlAttribute(&quot;attr&quot;)]
    	    public int Value { get; set; }

    	    [XmlIgnore]
    	    public bool ValueSpecified;
        }

 3. [Custom Nullable class like in this blog post by Alex Scordellis][3]

 I tried to adopt the class from this blog post to my problem:

        [XmlAttribute(&quot;attr&quot;)]
        public NullableInt Value { get; set; } 

 But XmlSerializer constructor fails with InvalidOperationException:

 &gt;Cannot serialize member &#39;Value&#39; of type TestConsoleApplication.NullableInt. 

 &gt;XmlAttribute/XmlText cannot be used to encode types implementing IXmlSerializable }

 4. Ugly surrogate solution (shame on me that I wrote this code here :) ):

        public class Element
        {
            [XmlAttribute(&quot;attr&quot;)]
            public string SetValue { get; set; }
    
            public int? GetValue()
            {
                if ( string.IsNullOrEmpty(SetValue) || SetValue.Trim().Length &lt;= 0 )
                    return null;
    
                int result;
                if (int.TryParse(SetValue, out result))
                    return result;
    
                return null;
            }
        }

 But I don’t want to come up with the solution like this because it breaks interface of my  class for its consumers. I would better manually implement IXmlSerializable interface.

Currently it looks like I have to implement IXmlSerializable for the whole Element class (it is big) and there are no simple workaround…

Deserializing empty xml attribute value into nullable int property using XmlSerializer

What are the advantages and disadvantages of storing JSON data in MySQL database vs. serialized array?

JSON vs. Serialized Array in database

I would like to XML serialize an object that has (among other) a property of type *IModelObject* (which is an interface).

    public class Example
    {
        public IModelObject Model { get; set; }
    }

When I try to serialize an object of this class,  I receive the following error: &lt;br/&gt;
&quot;Cannot serialize member Example.Model of type Example because it is an interface.&quot;

I understand that the problem is that an interface cannot be serialized. However, the concrete *Model* object type is unknown until runtime.

Replacing the *IModelObject* interface with an abstract or concrete type and use inheritance with XMLInclude is possible, but seems like an ugly workaround.

Any suggestions?

I would like to deep clone a List. for that we are having a method

    // apache commons method. This object should be serializable
    SerializationUtils.clone ( object ) 

so now to clone my List i should convert that to serializable first. Is it possible to convert a List into Serializable list?
