        if (input.toLowerCase().indexOf(alphabets[i]) == -1) {
            isPangram = false;

Draw a line from x,y with a given angle and length

Draw a line from x,y with a given angle and length. DEMO Fiddle

function drawLine(x1,y1,r,theta){
    ctx.clearRect(0, 0, c.width, c.height);    
    ctx.beginPath();
    ctx.moveTo(x1, y1);
    ctx.lineTo(x1 + r * Math.cos(Math.PI * theta / 180.0), y1 + r * Math.sin(Math.PI * theta / 180.0));   
    ctx.closePath();
    ctx.stroke();
  }

Angular Bind Model to Model

I had a scenario, i have to show 4 inputs. In which 4th input is the sum of other 3. this should be easy, but the challenging factor is that i have to save the last input value in a model. So the scenario changed to “Give value for a model from another three model” and the change should be dynamic. Here is the solution i found for that. 🙂 DEMO

<input type="text" ng-model="textInput1" id="textBoxval1" value="temp2"/>
<input type="text" ng-model="textInput2" id="textBoxval2" value="temp2"/>
<input type="text" ng-model="textInput3" id="textBoxval3" value="temp2"/>
<input type="text" ng-model="textInputT" id="textBoxvalT" 
value = "{{textInputT=textInput1 +'-'+ textInput2 +'-'+ textInput3}}"/>
