Question: 1

You are validating user input by using JavaScript and regular expressions.

A group of predefined regular expressions will validate two input fields:

An email address in a function named validateEmail (for example, firstname@contoso.com)

A nine-digit number that allows optional hyphens after the second and fifth character in a function named validateSSN(for example, 555555555 or 555-55-5555)

You need to use the correct expression to validate the input.

Which expression should you insert into each function? (To answer, drag the appropriate regular expression statement to the correct location. Each regular expression statement may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.)

Question: 4

DRAG DROP

You are developing a form that captures a user’s email address by using HTML5 and jQuery.

The form must capture the email address and return it as a query string parameter. The query string parameter must display the @ symbol that is used in the email address.

You need to implement this functionality.

How should you develop the form? (To answer, drag the appropriate code segment to the correct target or targets in the answer area. Each code segment may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.)

Answer:

Explanation:

* The serialize() method creates a URL encoded text string by serializing form values.

You can select one or more form elements (like input and/or text area), or the form element itself.

The serialized values can be used in the URL query string when making an AJAX request.

Example: $(“form”).serialize());

* decodeURIComponent

The decodeURIComponent() function decodes a URI component.

Return Value:A String, representing the decoded URI

Incorrect:

Not decodeURI:

decodeURI is intended for use on the full URI.

decodeURIComponent is intended to be used on .. well .. URI components that is any part that lies between separators (; / ? : @ & = + $ , #).

The data being retrieved is a custom binary datatype named bint. The data can also be represented in XML.Two existing methods named parseXml() and parseBint() are defined on the page.The application must:Retrieve and parse data from the web service using binary format if possibleRetrieve and parse the data from the web service using XML when binary format is not possibleYou need to develop the application to meet the requirements.What should you do? (To answer, select the appropriate options from the drop-down lists in the answer area.) Answer: * accepts : ‘application/bint, text/xml’accepts:’application/bin,text/xml’ to accept only XML and binary content in HTML responses.* Use the following condition to check if the html response content is binary: If(request.getResponseHeader(“Content-Type”)==”application/bint”* var request = $.ajax({ uri:’/’, accepts: ‘application/bint, text/xml’, datafilter: function(data,type){ if(request.getResponseHeader(“Content-Type”)==”application/bint”) return parseBint(data); else return parseXml(); }, success: function (data) { start(data); } }); Question: 9You are developing a customer web form that includes the following HTML.A customer must enter a value in the text box prior to submitting the form.You need to add validation to the text box control.Which HTML should you use?

Question: 12 You are creating a class named Consultant that must inherit from the Employee class. The Consultant class must modify the inherited PayEmployee method. The Employee class is defined as follows.function Employee() {}Employee.prototype.PayEmployee = function ( ){alert(‘Hi there!’);}Future instances of Consultant must be created with the overridden method.You need to write the code to implement the Consultant class.Which code segments should you use? (Each correct answer presents part of the solution. Choose two.) A. Consultant.PayEmployee = function (){alert(‘Pay Consulant’);}B. Consultant.prototype.PayEmployee = function (){alert(‘Pay Consultant’);}C. function Consultant () {Employee.call(this);}Consultant.prototype = new Employee();Consultant.prototype.constructor = Consultant;D. function Consultant() {Employee.call(this); }Consultant.prototype.constructor = Consultant.create; Answer: B, C * Object.prototype.constructorReturns a reference to the Object function that created the instance’s prototype. Note that the value of this property is a reference to the function itself, not a string containing the function’s name. The value is only read-only for primitive values such as 1, true and “test”.* The constructor property is created together with the function as a single property of func.prototype.Reference: Object.prototype.constructor Question: 13 You are modifying an existing web page.
