Use [`:not`][1] CSS pseudo-class:

    document.querySelectorAll(&#39;span.test:not(.asd)&#39;);

Use the [CSS&#39;s negation pseudo-selector, `:not()`][1]:

    document.querySelectorAll(&#39;span.test:not(.asd)&#39;);

&gt; The negation pseudo-class, `:not(X)`, is a functional notation taking a simple selector (excluding the negation pseudo-class itself) as an argument. It represents an element that is not represented by its argument.

Element by tagName and ignore or exclude element that have a specific class:
```
document.querySelectorAll(`svg,div:not([class*=&quot;background&quot;]`)

I&#39;m using rails 4.1.5 with postgresql 9.1 under Debian 7, and I&#39;m not able to create a database in my development environment. When I run

    bin/rake db:create

I get

    home/rs/.rvm/gems/ruby-2.1.2/gems/activerecord-4.1.5/lib/active_record/connection_adapters/postgresql_adapter.rb:898:in `rescue in connect&#39;: FATAL:  database &quot;direct-dev&quot; does not exist
    Run `$ bin/rake db:create db:migrate` to create your database (ActiveRecord::NoDatabaseError)
	from /home/rs/.rvm/gems/ruby-2.1.2/gems/activerecord-4.1.5/lib/active_record/connection_adapters/postgresql_adapter.rb:888:in `connect&#39;
    from ...

I am trying to create the database so, naturally, it does not exist. However rails should create it ... Here&#39;s my config/database.yml:

    default: &amp;default
      adapter: postgresql
      encoding: unicode
      pool: 5
    
    development:
      &lt;&lt;: *default
      database: direct-dev

And here&#39;s a part of the postgresql log:

    2014-09-01 19:30:40 CEST LOG:  connection received: host=[local]
    2014-09-01 19:30:40 CEST LOG:  connection authorized: user=rs database=direct-dev
    2014-09-01 19:30:40 CEST FATAL:  database &quot;direct-dev&quot; does not exist

Do you have any pointers? I&#39;ve been at this for more than an hour, and still can&#39;t understand why this is happening ...

Thanks!

rake db:create throws &quot;database does not exist&quot; error with postgresql

I have to create a custom `UIView` that will have round corners, a border, a shadow and its `drawRect()` method is overridden to provide custom drawing code with which several straight lines are drawn into the view (I need to use a fast, lightweight approach here since many of these views may be rendered).

The problem I&#39;m currently facing is that the shadow doesn&#39;t apply anymore to the round corners as soon as I override `drawRect()` in the view class (even without any custom code yet in it). See the attached image for the difference:

![enter image description here][1]


In the view controller I&#39;m using the following code:

		view.layer.cornerRadius = 10;
		view.layer.masksToBounds = true;
		
		view.layer.borderColor = UIColor.grayColor().CGColor;
		view.layer.borderWidth = 0.5;
		
		view.layer.contentsScale = UIScreen.mainScreen().scale;
		view.layer.shadowColor = UIColor.blackColor().CGColor;
		view.layer.shadowOffset = CGSizeZero;
		view.layer.shadowRadius = 5.0;
		view.layer.shadowOpacity = 0.5;
		view.layer.masksToBounds = false;
		view.clipsToBounds = false;

In the overridden `drawContext()` I would use something like:

		var context:CGContext = UIGraphicsGetCurrentContext();
		CGContextSetStrokeColorWithColor(context, UIColor.redColor().CGColor);
		// Draw them with a 2.0 stroke width so they are a bit more visible.
		CGContextSetLineWidth(context, 2.0);
		CGContextMoveToPoint(context, 0.0, 0.0); //start at this point
		CGContextAddLineToPoint(context, 20.0, 20.0); //draw to this point
		CGContextStrokePath(context);

But as said above, the shadow problem occurs even without this code added.

Is there any other/better way to draw lightweight elements onto a view other than this approach that is compatible with round corners and shadows? I don&#39;t want to add any unnecessary extra views or image contexts to the view since these need to be light and performant.

How can I exclude tag elements that have a specific class name?

    &lt;span class=&quot;test&quot; /&gt;
    &lt;span class=&quot;test asd&quot; /&gt;
    
    document.querySelectorAll(&#39;span.test&#39;); //how to exclude all spans with &quot;asd&quot; as class name?

I have a route.js which looks like this:

    module.exports = function(app) {

      app.get(&#39;/tip&#39;, function(req, res) {
        res.render(&quot;tip&quot;);
      });

      app.get(&#39;/article&#39;, function(req, res) {
       res.render(&quot;article&quot;);
      });

      app.get(&#39;/article1&#39;, function(req, res) {
       res.render(&quot;article1&quot;);
      });

      app.get(&#39;/article2&#39;, function(req, res) {
       res.render(&quot;article2&quot;);
      });

      app.get(&#39;/article3&#39;, function(req, res) {
       res.render(&quot;article3&quot;);
      });

      app.get(&#39;/modules/:name&#39;, function(req, res) {
        var name = req.params.name;
        res.render(&#39;modules/&#39; + name);
      });

      app.get(&#39;/modules/esaver/:name&#39;, function(req, res) {
        var name = req.params.name;
        res.render(&#39;modules/esaver/&#39; + name);
      });

    };

Considering i have over 200 different routes to create, i would end up with stuff like &#39;article1&#39;, &#39;article2&#39; etc

and my app.js is like:

    var express = require(&#39;express&#39;)
      ,http = require(&#39;http&#39;)
      ,fs = require(&#39;fs&#39;)
      ,path = require(&#39;path&#39;);

    var app = express();

    html_templates = __dirname + &#39;/html_templates&#39;;

    app.set(&#39;views&#39;, html_templates + &#39;/views&#39;);
    app.set(&#39;view engine&#39;, &#39;jade&#39;);

    app.use(&#39;/Core&#39;, express.static(__dirname + &#39;/Core&#39;));


    app.listen(3000, function () {
     console.log(&quot;express has started on port 3000&quot;);
    });

    require(&#39;./html_templates/controller/routes.js&#39;)(app);

Is there any dynamic way to create this?

I want to have the exact distance between the Y-coordinate of an element an the Y-value=0, which I consider as the top of the document.

    myElement.getBoundingClientRect().top;

But the value of getBoundingClientRect() seems to change while scrolling. How can I get the real distance between myElement and the Y-coordinate=0 (top of document)?

If I do:
				

    var number = 3500;
    alert(number.toLocaleString(&quot;hi-IN&quot;));

I will get `३,५००` in Hindi.

But how can I convert it back to `3500`.
I want something like:

    var str=&#39;३,५००&#39;;
    alert(str.toLocaleNumber(&quot;en-US&quot;));

So, that it can give `3500`.

Is it possible by javascript or jquery?

I&#39;ve written some code to render repeating elements in ReactJS, but I hate how ugly it is.

    render: function(){
      var titles = this.props.titles.map(function(title) {
        return &lt;th&gt;{title}&lt;/th&gt;;
      });
      var rows = this.props.rows.map(function(row) {
        var cells = [];
        for (var i in row) {
          cells.push(&lt;td&gt;{row[i]}&lt;/td&gt;);
        }
        return &lt;tr&gt;{cells}&lt;/tr&gt;;
      });
      return (
        &lt;table className=&quot;MyClassName&quot;&gt;
          &lt;thead&gt;
            &lt;tr&gt;{titles}&lt;/tr&gt;
          &lt;/thead&gt;
          &lt;tbody&gt;{rows}&lt;/tbody&gt;
        &lt;/table&gt;
      );
    } 

Is there a better way to achieve this?

How can I render repeating React elements?

I need to pass and recieve two parameters to the state I want to transit to using `ui-sref` of ui-router.

Something like using the link below for transitioning the state to `home` with `foo` and `bar` parameters:

    &lt;a ui-sref=&quot;home({foo: &#39;fooVal&#39;, bar: &#39;barVal&#39;})&quot;&gt;Go to home state with foo and bar parameters &lt;/a&gt;

Receiving `foo` and `bar` values in a controller:

    app.controller(&#39;SomeController&#39;, function($scope, $stateParam) {
      //..
      var foo = $stateParam.foo; //getting fooVal
      var bar = $stateParam.bar; //getting barVal
      //..
    });     

I get `undefined` for `$stateParam` in the controller.

Could somebody help me understand how to get it done?

**Edit:**

    .state(&#39;home&#39;, {
      url: &#39;/&#39;,
      views: {
        &#39;&#39;: {
          templateUrl: &#39;home.html&#39;,
          controller: &#39;MainRootCtrl&#39;
    
        },
    
        &#39;A@home&#39;: {
          templateUrl: &#39;a.html&#39;,
          controller: &#39;MainCtrl&#39;
        },
    
        &#39;B@home&#39;: {
          templateUrl: &#39;b.html&#39;,
          controller: &#39;SomeController&#39;
        }
      }
    
    });
