Use the [`:not()`](http://api.jquery.com/not-selector/) selector.

    $(&#39;.funding-plan-container:not([data-timestamp])&#39;)

---

This, by the way, is a valid [*Selectors API*](http://www.w3.org/TR/selectors-api/) selector, so it isn&#39;t specific to jQuery. It&#39;ll work with `querySelectorAll()` and in your CSS *(given [browser support][1])*.

You can filter the selector by using **[.not()][1]** or **[:not()][2]** selector.

    $(&#39;.funding-plan-container:not([data-timestamp])&#39;).

OR

    $(&#39;.funding-plan-container&#39;).not(&#39;[data-timestamp]&#39;)

Try it with the `:not()` pseudo-class selector: http://api.jquery.com/not-selector/

    $(&#39;.funding-plan-container:not([data-timestamp])&#39;)

I am using the [`requests` module][1].
I have figured out how to submit data to a login form on a website and retrieve the session key, but I can&#39;t see an obvious way to use this session key in subsequent requests.
Can someone fill in the ellipsis in the code below or suggest another approach?

    &gt;&gt;&gt; import requests
    &gt;&gt;&gt; login_data =  {&#39;formPosted&#39;: &#39;1&#39;, &#39;login_email&#39;: &#39;me@example.com&#39;, &#39;password&#39;: &#39;pw&#39;}
    &gt;&gt;&gt; r = requests.post(&#39;https://localhost/login.py&#39;, login_data)
    &gt;&gt;&gt; 
    &gt;&gt;&gt; r.text
    &#39;You are being redirected &lt;a href=&quot;profilePage?_ck=1349394964&quot;&gt;here&lt;/a&gt;&#39;
    &gt;&gt;&gt; r.cookies
    {&#39;session_id_myapp&#39;: &#39;127-0-0-1-825ff22a-6ed1-453b-aebc-5d3cf2987065&#39;}
    &gt;&gt;&gt; 
    &gt;&gt;&gt; r2 = requests.get(&#39;https://localhost/profile_data.json&#39;, ...)

How would you implement the Cartesian product of multiple arrays in JavaScript?

As an example,

    cartesian([1, 2], [10, 20], [100, 200, 300]) 

should return

    [
      [1, 10, 100],
      [1, 10, 200],
      [1, 10, 300],
      [2, 10, 100],
      [2, 10, 200]
      ...
    ]

I can find a div that has an attribute like so:

    $(&#39;.funding-plan-container[data-timestamp]&#39;)

But if I try to find a div that does not have that attribute, I get an error - my code is:

    $(&#39;.funding-plan-container[!data-timestamp]&#39;)

Is there a &quot;does not have attribute&quot; selector in jQuery?

For reference, the use case here is that any div that does not have a timestamp attribute was not added dynamically, and hence is useful.

Thanks!

jQuery &quot;Does not have attribute&quot; selector?

The following code initializes a leaflet map. The initialize function centers the map based on user location. How do I change the center of the map to a new position after calling the initialize function?

    function initialize() {
	map = L.map(&#39;map&#39;);
	L.tileLayer(&#39;http://{s}.tile.cloudmade.com/BC9A493B41014CAABB98F0471D759707/997/256/{z}/{x}/{y}.png&#39;, {
		maxZoom: 18,

	}).addTo(map);

	map.locate({setView: true, maxZoom: 8});	
    }

I found the following snippet in Twitter&#39;s JavaScript files. Why do they need to call the `hasOwnProperty` function to see `dict` has the `key` property? The *for* loop is running for each &#39;key&#39; in &#39;dict&#39; which means &#39;dict&#39; has &#39;key&#39;. Am I missing a point?

    function forEach(dict, f) {
        for (key in dict) {
            if (dict.hasOwnProperty(key))
                f(key, dict[key]);

I checked here https://github.com/Microsoft/TypeScript/blob/master/doc/spec.md which is the [TypeScript Language Specifications][1] but I couldn&#39;t find how I can declare a return type of the function.

I showed what I was expecting in the code below: `greet(name:string): string {}`

```ts
class Greeter {
  greeting: string;
  constructor(message: string) {
    this.greeting = message;
  }
  greet(): string {
    return &quot;Hello, &quot; + this.greeting;
  }
}
```

I know I can use `(name:string) =&gt; any` but this is used mostly when passing callback functions around:

```ts
function vote(candidate: string, callback: (result: string) =&gt; any) {
  // ...
}
```

I&#39;m assuming that WebRTC is an API that decodes/encodes audio and video, although the communication between the server and the clients is done via web sockets, or some other network protocol? I&#39;m a bit confused. Does WebRTC have its own communications protocol?

WebRTC and Websockets. Is there a difference

Can I add any random attribute to &#39;window&#39; object in javascript? Some thing like:

    window.my_own_attr = &quot;my_value&quot;

Does it have any side effects with any libraries? And is it cross-browser compatible?

`.offset([coordinates])` method set the coordinates of an element but only relative to the document. Then how can I set coordinates of an element but relative to the parent?

I found that `.position()` method get only &quot;top,left&quot; values relative to the parent, but it doesn&#39;t set any values.

I tried with 

    $(&quot;#mydiv&quot;).css({top: 200, left: 200});

but does not work.

In jQuery how can I set &quot;top,left&quot; properties of an element with position values relative to the parent and not the document?
