You need to ensure that the values that users enter are only numbers, letters, and underscores, regardless of the order.

Which code segment should you insert at line 04?

Ensurepass 2018 PDF and VCE

  1. Option A

  2. Option B

  3. Option C

  4. Option D

Answer: A Explanation: Example:

Sometimes situations arise when user should fill a single or more than one fields with alphabet characters (A-Z or a-z) in a HTML form. You can write a JavaScript form validation script to check whether the required field(s) in the HTML form contains only letters. –

Javascript function to check for all letters in a field view plainprint?

function allLetter(inputtxt)

{

var letters = /^[A-Za-z] $/; if(inputtxt.value.match(letters))

{

return true;

}

else

{

alert(quot;messagequot;); return false;

}

}

To get a string contains only letters (both uppercase or lowercase) we use a regular expression (/^[A-Za-z] $/) which allows only letters. Next the match() method of string object is used to match the said regular expression against the input value.

Object Properties

The name:values pairs (in JavaScript objects) are called properties.

var person = {firstName:quot;Johnquot;, lastName:quot;Doequot;, age:50, eyeColor:quot;bluequot;};

Question No: 103 DRAG DROP – (Topic 3)

You develop an HTML application that calls a web service to retrieve JSON data. The web service contains one method named GetFullName that returns an Object named data. The data object contains two properties named GivenName and Surname.

You need to load data from the web service to the webpage.

How should you complete the relevant code? (To answer, drag the appropriate code segment or code segments to the correct location or locations in the answer area. Use only code segments that apply.)

Question No: 104 DRAG DROP – (Topic 3)

A company asks you to create a function that displays loan amounts to their customers.

You must create the function by using JavaScript to meet the following requirements:

-> Display three different loan amounts to each customer.

-> Display loan amounts in order starting with the greatest amount and ending with the least amount.

You need to implement the function.

How should you complete the relevant code? (To answer, drag the appropriate command or commands to the correct location or locations in the answer area. Use only commands

that apply.)

Answer:

Ensurepass 2018 PDF and VCE

Explanation:

Ensurepass 2018 PDF and VCE

  • The innermost assignment to the loanAmount variable should be the highest.

  • Local variables have local scope: They can only be accessed within the function. Example

// code here can not use carName function myFunction() {

var carName = quot;Volvoquot;;

// code here can use carName

}

* A variable declared outside a function, becomes GLOBAL.

A global variable has global scope: All scripts and functions on a web page can access it.

Example

var carName = quot; Volvoquot;;

// code here can use carName function myFunction() {

// code here can usecarName

}

* The alert() method displays an alert box with a specified message and an OK button.

An alert box is often used if you want to make sure information comes through to the user.

An XML file named message.xml resides on a web server. The structure of the file is as follows:

Ensurepass 2018 PDF and VCE

You are developing a code-based solution to parse the contents of the XML file and display the information on the page.

The solution must work on both modern and older browsers.

You need to display the information from the XML file onto the page.

How should you create the JavaScript code? (Develop the solution by selecting the required code segments and arranging them in the correct order. You may not need all of the code segments.)

Note:

Parse an XML Document

Example. The following code fragment parses an XML document into an XML DOM object: if (window.XMLHttpRequest) {// code for IE7 , Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); }else {// code for IE6, IE5 xmlhttp=new ActiveXObject(quot;Microsoft.XMLHTTPquot;);

}xmlhttp.open(quot;GETquot;,quot;books.xmlquot;,false);xmlhttp.send();xmlDoc=xmlhttp.responseXML;

Question No: 106 – (Topic 3)

You develop an HTML5 application that allows users to upload files from their local computers.

The user interface must remain responsive during the upload.

You need to implement the file upload functionality for the application.

Which two actions should you perform? (Each correct answer presents a complete solution. Choose two.)

  1. Use an HTML form with a file type INPUT element that targets a hidden IFRAME element.

  2. Use a file type INPUT element, and then use the Web Storage API to upload the file.

  3. Use a FormData object and upload the file by using XMLHttpRequest.

  4. Register the file protocol by using protocol handler registration API and then upload the file by using XMLHttpRequest.

  5. Use the FileSystem API to load the file, and then use the jQuery post method to upload the file to the server.

Answer: B,D

Explanation: B: Example (notice the web storage api upload.aspx):

lt;!DOCTYPE htmlgt;

lt;htmlgt;

lt;headgt;

lt;titlegt;Upload Files using XMLHttpRequest – Minimallt;/titlegt;

lt;/headgt;

lt;bodygt;

lt;form id=quot;form1quot; enctype=quot;multipart/form-dataquot; method=quot;postquot; action=quot;Upload.aspxquot;gt;

lt;div class=quot;rowquot;gt;

lt;label for=quot;fileToUploadquot;gt;Select a File to Uploadlt;/labelgt;lt;br /gt;

lt;input type=quot;filequot; name=quot;fileToUploadquot; id=quot;fileToUploadquot; onchange=quot;fileSelected();quot;/gt;

lt;/divgt;

lt;div id=quot;fileNamequot;gt;lt;/divgt;

lt;div id=quot;fileSizequot;gt;lt;/divgt;

lt;div id=quot;fileTypequot;gt;lt;/divgt;

lt;div class=quot;rowquot;gt;

lt;input type=quot;buttonquot; onclick=quot;uploadFile()quot; value=quot;Uploadquot; /gt;

lt;/divgt;

lt;div id=quot;progressNumberquot;gt;lt;/divgt;

lt;/formgt;

lt;/bodygt;

lt;/htmlgt;

D:

  • Because we#39;re using XMLHttpRequest, the uploading is happening in the background. The page the user is on remains intact. Which is a nice feature to have if your business process can work with it.

  • The XMLHttpRequest object has gotten a facelift in the Html5 specifications. Specifically the XMLHttpRequest Level 2 specification (currently the latest version) that has included the following new features:

Handling of byte streams such as File, Blob and FormData objects for uploading and downloading

Progress events during uploading and downloading Cross-origin requests

Allow making anonymous request – that is not send HTTP Referer The ability to set a Timeout for the Request

Question No: 107 – (Topic 3)

You develop an HTML5 web application. The web application contains a form that allows users to enter only their month of birth.

The value that the users enter must be numbers between 1 and 12, inclusive. You need to implement the form element for the month of birth.

Which element should you use?

  1. lt;input type=quot;timequot; options=quot;monthquot; /gt;

  2. lt;input types=quot;submitquot; value=quot;monthquot; /gt;

  3. lt;input type=quot;rangequot; min=quot;1quot; max=quot;12quot; /gt;

  4. lt;input type=quot;monthquot; itemscope=quot;numericquot; /gt;

Answer: C Explanation: Example:

lt;/headgt;

lt;bodygt;

lt;input type=quot;rangequot; name=quot;rangeInputquot; min=quot;0quot; max=quot;100quot; onchange=quot;updateTextInput(this.value);quot;gt;

lt;input type=quot;textquot; id=quot;textInputquot; value=quot;quot;gt;

lt;/bodygt;

lt;/htmlgt;

  • text-shadow

  • hyphens: auto

Words can be broken at appropriate hyphenation points either as determined by hyphenation characters) inside the word or as determined automatically by a language- appropriate hyphenation resource (if supported by the browser or provided via

@hyphenation-resource).

Conditional hyphenation characters inside a word, if present, take priority over automatic resources when determining hyphenation points within the word.

Question No: 110 – (Topic 3)

You are creating a page that contains detailed employee information for a company portal. The page uses a jQuery library. The page contains a hidden button named btnEdit that is defined by the following code.

lt;button id=quot;btnEditquot; style=quot;display: none;gt;Editlt;/buttongt; The button is not displayed by default.

The button must be displayed only if the user is logged on.

You need to add code to the document.ready() function to meet the requirements for the button.

Which line of code should you use?

  1. $ (‘#btnEdit’).appear ();

  2. $ (‘#btnEdit’).visible = true;

  3. $ (‘#btnEdit’).show();

  4. $ (‘#btnEdit’).Visible();

Answer: C

Explanation: With jQuery, you can hide and show HTML elements with the hide() and show() methods:

Example

$(quot;#hidequot;).click(function(){

$(quot;pquot;).hide();

});

$(quot;#showquot;).click(function(){

$(quot;pquot;).show();

});
