There is no such functionality in jQuery. Use `JSON.stringify` or alternatively any jQuery plugin with similar functionality (e.g [jquery-json](https://code.google.com/p/jquery-json/)).

I got some simple code:

    def find(str, ch):
        for ltr in str:
            if ltr == ch:
                return str.index(ltr)
    find(&quot;ooottat&quot;, &quot;o&quot;)

The function only return the first index. If I change return to print, it will print 0 0 0. Why is this and is there any way to get `0 1 2`?

I&#39;ve managed to generate a series of list-items based on one specified array within a matrix (i.e. an array within an array).

I would like to be able to pass a variable (representing an array) to a function so that it can spit out an unordered list filled with list-items based on the array passed into it.

**Problems:**

* The function only works with one array at a time
* It also produces commas in the markup (presumably, because it&#39;s converting the array to a string)

**The solution needs to:**

* assume that the unordered list does not exist in the DOM
* be able to accept different arrays passed into it (`options[0]`, `options[1]`, etc.)
* generate the list-items without commas

**JavaScript:**

&lt;!-- language: lang-js --&gt;

    var options = [
            set0 = [&#39;Option 1&#39;,&#39;Option 2&#39;],
            set1 = [&#39;First Option&#39;,&#39;Second Option&#39;,&#39;Third Option&#39;]
        ]
    
    function makeUL(){
        var a = &#39;&lt;ul&gt;&#39;,
            b = &#39;&lt;/ul&gt;&#39;,
            m = [];
    
        // Right now, this loop only works with one
        // explicitly specified array (options[0] aka &#39;set0&#39;)
        for (i = 0; i &lt; options[0].length; i += 1){
            m[i] = &#39;&lt;li&gt;&#39; + options[0][i] + &#39;&lt;/li&gt;&#39;;
        }
    
        document.getElementById(&#39;foo&#39;).innerHTML = a + m + b;
    }
        
    // My goal is to be able to pass a variable
    // here to utilize this function with different arrays
    makeUL();

I have a DOM element with some/all of the following effects applied: 

    #elem {
      -webkit-transition: height 0.4s ease;
      -moz-transition: height 0.4s ease;
      -o-transition: height 0.4s ease;
      transition: height 0.4s ease;
    }

I am writing a jQuery plugin that is resizing this element, I need to disable these effects temporarily so I can resize it smoothly. 

What is the most elegant way of disabling these effects temporarily (and then re-enabling them), given they may be applied from parents or may not be applied at all.

[wikipedia](http://en.wikipedia.org/wiki/Web_Sockets) appears to infers `websockets` are secure:

&lt;blockquote&gt;
For web browser support, a secure version of the WebSocket protocol is implemented in Firefox 6 (named MozWebSocket),[2] Google Chrome 14[3] and Internet Explorer 10 developer preview.
... Although there are no known exploits, it was disabled in Firefox 4 and 5...
&lt;/blockquote&gt;

but [w3](http://www.w3.org/TR/websockets/) states they are insecure:

&lt;blockquote&gt;
Following HTTP procedures here could introduce serious security problems in a Web browser context. For example, consider a host with a WebSocket server at one path and an open HTTP redirector at another. Suddenly, any script that can be given a particular WebSocket URL can be tricked into communicating to (and potentially sharing secrets with) any host on the Internet, even if the script checks that the URL has the right hostname.
&lt;/blockquote&gt;

1. are `http websockets` (ws:) secure or not?

2. are `https websockets` (wss:) secure or not?

3. if not #2, are there documented prophylactic measures?

So I have successfully gotten AJAX requests to work before but I have always had to use a form, and then at the end of the submit do return false so that it doesn&#39;t refresh the page.

I have also just recently moved my JavaScript into a separate file this has caused my @ commands to fail. Because of this I do not no how to set my URL to my route?

HTML:

    &lt;button id=&quot;saveAsDefaultButton&quot;&gt;Save as default&lt;/button&gt;

Playframework Java code:

    public static Result saveDefaultPhoneForUser(String handset) {
		User currentUser = User.findByName(session(&quot;name&quot;));
		currentUser.lastControlledHandset = theHandset;
		currentUser.save();
		return ok();
	}

routes:

    POST	/							controllers.Application.saveDefaultPhoneForUser(handset : String)

javascript:

    $(&#39;#saveAsDefaultButton&#39;).click(function(evt) {
			$(&#39;#errors&#39;).hide();
			$.ajax({
				type : &#39;POST&#39;,
				url : &quot;controllers.Application.saveDefaultPhoneForUser&quot;,
				data : $(&#39;#controlledPhone option:selected&#39;).text(),
				dataType : &quot;text&quot;,
				success : function(data) {
					//setError(&#39;Call succedded&#39;);
					//$(&#39;#test1&#39;).attr(&quot;src&quot;, data)
				},
				error : function(data) {
					setError(&#39;Make call failed&#39;);
				}
			});
			return false;
		});

I&#39;m sure there is a way to do this but I am just having no luck finding anything.

I have a filename that can have multiple dots in it and could end with any extension:

    tro.lo.lo.lo.lo.lo.png

I need to use a regex to replace the last occurrence of the dot with another string like `@2x` and then the dot again (very much like a retina image filename) i.e.:

    tro.lo.png -&gt; tro.lo@2x.png

Here&#39;s what I have so far but it won&#39;t match anything...

Here is my simple `User` POCO class:

&lt;!-- language: lang-cs --&gt;

    /// &lt;summary&gt;
    /// The User class represents a Coderwall User.
    /// &lt;/summary&gt;
    public class User
    {
        /// &lt;summary&gt;
        /// A User&#39;s username. eg: &quot;sergiotapia, mrkibbles, matumbo&quot;
        /// &lt;/summary&gt;
        public string Username { get; set; }
    
        /// &lt;summary&gt;
        /// A User&#39;s name. eg: &quot;Sergio Tapia, John Cosack, Lucy McMillan&quot;
        /// &lt;/summary&gt;
        public string Name { get; set; }
    
        /// &lt;summary&gt;
        /// A User&#39;s location. eh: &quot;Bolivia, USA, France, Italy&quot;
        /// &lt;/summary&gt;
        public string Location { get; set; }
            
        public int Endorsements { get; set; } //Todo.
        public string Team { get; set; } //Todo.
    
        /// &lt;summary&gt;
        /// A collection of the User&#39;s linked accounts.
        /// &lt;/summary&gt;
        public List&lt;Account&gt; Accounts { get; set; }
    
        /// &lt;summary&gt;
        /// A collection of the User&#39;s awarded badges.
        /// &lt;/summary&gt;
        public List&lt;Badge&gt; Badges { get; set; }
    
    }

And the method I&#39;m using to deserialize a JSON response into a `User` object (this actual [JSON call is here][1]):

&lt;!-- language: lang-cs --&gt;

    private User LoadUserFromJson(string response)
    {
        var outObject = JsonConvert.DeserializeObject&lt;User&gt;(response);
        return outObject;
    }

This fires an exception:

&gt; Cannot deserialize the current JSON object (e.g. {&quot;name&quot;:&quot;value&quot;})
&gt; into type
&gt; &#39;System.Collections.Generic.List`1[CoderwallDotNet.Api.Models.Account]&#39;
&gt; because the type requires a JSON array (e.g. [1,2,3]) to deserialize
&gt; correctly. 
&gt;
&gt; To fix this error either change the JSON to a JSON array
&gt; (e.g. [1,2,3]) or change the deserialized type so that it is a normal
&gt; .NET type (e.g. not a primitive type like integer, not a collection
&gt; type like an array or List&lt;T&gt;) that can be deserialized from a JSON
&gt; object. JsonObjectAttribute can also be added to the type to force it
&gt; to deserialize from a JSON object. Path &#39;accounts.github&#39;, line 1,
&gt; position 129.

Having never worked with this DeserializeObject method before, I&#39;m kind of stuck here.

I&#39;ve made sure that the property names in the POCO class are the same as the names in the JSON response. 

What can I try to deserialize JSON into this POCO class?

Using JsonConvert.DeserializeObject to deserialize Json to a C# POCO class

Is there a technical reason why unexported fields are not included by encoding/json? If not and it is an arbitrary decision could there be an additional back door option (say &#39;+&#39;) to include even though unexported?

Requiring client code to export to get this functionality feels unfortunate, especially if lower case is providing encapsulation or the decision to marshal structures comes much later than design of them.

How are people dealing with this? Just export everything?

Also, doesn&#39;t exporting field names make it difficult to follow suggested idioms. I think if a struct X has field Y, you can not have an accessor method Y(). If you want to provide interface access to Y you have to come up with a new name for the getter and no matter what you&#39;ll get something un-idiomatic according to http://golang.org/doc/effective_go.html#Getters

I am using JSON.NET in C# to parse a response from the Klout API. My response is like this:

As you see, it contains 5 `id` tags.  Maybe next time it would be 6 or 1 or some other number.  I want to iterate over the JSON and get the value of each `id` tag.  I can&#39;t run a loop without knowing how many there will be.  How can I solve this?

I&#39;m stringyfing an object like `{&#39;foo&#39;: &#39;bar&#39;}`

How can I turn the string back to an object?

Reverse of JSON.stringify?

I have a nested JSON object that I need to loop through, and the value of each key could be a String, JSON array or another JSON object. Depending on the type of object, I need to carry out different operations. Is there any way I can check the type of the object to see if it is a String, JSON object or JSON array?

I tried using `typeof` and `instanceof` but both didn&#39;t seem to work, as `typeof` will return an object for both JSON object and array, and `instanceof` gives an error when I do `obj instanceof JSON`.

To be more specific, after parsing the JSON into a JS object, is there any way I can check if it is a normal string, or an object with keys and values (from a JSON object), or an array (from a JSON array)?

For example:

JSON

    var data = &quot;{&#39;hi&#39;:
                 {&#39;hello&#39;:
                   [&#39;hi1&#39;,&#39;hi2&#39;]
                 },
                &#39;hey&#39;:&#39;words&#39;
               }&quot;;
Sample JavaScript

    var jsonObj = JSON.parse(data);
    var path = [&quot;hi&quot;,&quot;hello&quot;];
    
    function check(jsonObj, path) {
        var parent = jsonObj;
        for (var i = 0; i &lt; path.length-1; i++) {
            var key = path[i];
            if (parent != undefined) {
                parent = parent[key];
            }
        }
        if (parent != undefined) {
            var endLength = path.length - 1;
            var child = parent[path[endLength]];
            //if child is a string, add some text
            //if child is an object, edit the key/value
            //if child is an array, add a new element
            //if child does not exist, add a new key/value
        }
    }
How do I carry out the object checking as shown above?
