Ensurepass 2018 PDF and VCE

When readyState is 4 and status is 200, the response is ready:

Example xmlhttp.onreadystatechange=function()

{

if (xmlhttp.readyState==4 amp;amp; xmlhttp.status==200)

{

document.getElementById(quot;myDivquot;).innerHTML=xmlhttp.responseText;

}

}

Note:

* readyState == 4

Holds the status of the XMLHttpRequest. Changes from 0 to 4: 0: request not initialized

1: server connection established 2: request received

3: processing request

4: request finished and response is ready

* status==200 200: quot;OKquot;

404: Page not found

The page contains the following JavaScript code. (Line numbers are included for reference only.)

Ensurepass 2018 PDF and VCE

The text on the canvas must rotate 90 degrees when a user clicks a button on the page. You need to ensure that the text rotates when the user clicks the button.

Which line of code should you add at line 03?

  2. context.content.getRotation(90);

  3. context.rotate(90);

  4. context.content.rotate (90);

Answer: C

Example

Rotate the rectangle 20 degrees:

JavaScript:

var c=document.getElementById(quot;myCanvasquot;); var ctx=c.getContext(quot;2dquot;); ctx.rotate(20*Math.PI/180); ctx.fillRect(50,20,100,50);

  • box-sizing

    The box-sizing property is used to tell the browser what the sizing properties (width and height) should include.

  • border-radius

The border-radius property is a shorthand property for setting the four border-*-radius properties.

border: 2px solid; border-radius: 25px;

}

Question No: 126 DRAG DROP – (Topic 3)

You are developing a shared library to format information. The library contains a method named _private.

* Here there is a basic example:

// our constructor

function Person(name, age){ this.name = name;

this.age = age;

};

// prototype assignment Person.prototype = (function(){

// we have a scope for private stuff

// created once and not for every instance function toString(){

return this.name quot; is quot; this.age;

};

// create the prototype and return them return {

// never forget the constructor … constructor:Person,

// quot;magicquot; toString method toString:function(){

// call private toString method return toString.call(this);

}

};

})();

* Example:

You can simulate private methods like this:

function Restaurant() {

}

Restaurant.prototype = (function() { var private_stuff = function() {

// Private code here

};

return { constructor:Restaurant,

use_restroom:function() { private_stuff();

}

};

})();

var r = new Restaurant();

// This will work: r.use_restroom();

// This will cause an error: r.private_stuff();

* onreadystatechange

When a request to a server is sent, we want to perform some actions based on the response.

The onreadystatechange event is triggered every time the readyState changes. The readyState property holds the status of the XMLHttpRequest.

Example xmlhttp.onreadystatechange=function()

{

if (xmlhttp.readyState==4 amp;amp; xmlhttp.status==200)

{

document.getElementById(quot;myDivquot;).innerHTML=xmlhttp.responseText;

}

}

* Send a Request To a Server

To send a request to a server, we use the open() and send() methods of the XMLHttpRequest object:

xmlhttp.open(quot;GETquot;,quot;xmlhttp_info.txtquot;,true); xmlhttp.send();
