    <script> eval("x=10;y=20; document.write(x*y)");

    • 200

    • 20

    • 10

    • None of above

    Correct Answer
    A. 200
    Explanation
    The given script uses the eval() function to evaluate the JavaScript code as a string. It assigns the values 10 to x and 20 to y, and then calculates the product of x and y using the document.write() function. Therefore, the output of the script is 200.

    Rate this question:

  • 3. 

    <script> document.write("<br>" + eval("2+2"));

    • 2

    • 4

    • 2+2

    • None of above

    Correct Answer
    A. 4
    Explanation
    The given code snippet is using the eval() function to evaluate the expression "2+2" and then printing the result using the document.write() method. The expression "2+2" evaluates to 4, so the output of the code will be 4. Therefore, the correct answer is 4.

  • 4. 

    <script type="text/javascript"> var username = "someAgent"; if(username == "SomeAgent")                document.write("Welcome special agent"); else                document.write("Access Denied!"); for getting output"Welcome special agent" can we use .toUpperCase () or .toLowerCase () ??

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The correct answer is true because the .toUpperCase() or .toLowerCase() methods can be used to convert the value of the variable "username" to either all uppercase or all lowercase letters. Since the comparison in the if statement is checking for an exact match with "SomeAgent", using either of these methods would result in a match and the output "Welcome special agent" would be displayed.

    <html> <head> <title>JavaScript String indexOf() Method</title> </head> <body> <script type="text/javascript"> var str1 = new String( "This is string one" ); var index = str1.indexOf( "string" ); document.write("indexOf found String :" + index );

    • IndexOf found String :8

    • IndexOf found String :11

    • None of above

    Correct Answer
    A. IndexOf found String :8
    Explanation
    The correct answer is 8 because the indexOf() method in JavaScript returns the index of the first occurrence of a specified string within another string. In this case, the string "string" is found at index 8 in the string "This is string one".

    Rate this question:

  • 7. 

    var value = Math.min(100); document.write("<br />Fourth Test Value : " + value ); 

    • Fourth Test Value : 100

    • Fourth Test Value : 1

    • Fourth Test Value : 0

    • None of above

    Correct Answer
    A. Fourth Test Value : 100
    Explanation
    The Math.min() function is used to find the minimum value among a set of numbers. In this case, the function is called with only one parameter, which is 100. Since there are no other numbers to compare it to, the minimum value is simply 100. Therefore, the output is "Fourth Test Value : 100".

    Rate this question:

  • 8. 

    var value = Math.pow(0, 10); document.write("<br />Fourth Test Value : " + value ); Type question here

    • Fourth Test Value : 0

    • Fourth Test Value : 1

    • Fourth Test Value : 10

    • None of above

    Correct Answer
    A. Fourth Test Value : 0
    Explanation
    The correct answer is "Fourth Test Value : 0". The Math.pow() function is used to calculate the power of a number. In this case, 0 raised to the power of 10 is equal to 0. Therefore, the value variable will be assigned the value of 0.

    • None of above

    Correct Answer
    A. Third Test Value : -45
    Explanation
    The Math.ceil() function returns the smallest integer greater than or equal to a given number. In this case, the given number is -45.95. Since -45 is the smallest integer greater than or equal to -45.95, the value returned by Math.ceil(-45.95) is -45. Therefore, the correct answer is "Third Test Value : -45".

    • True

    • False

With the advent of e-commerce and online shopping, consumers now have the ability to access a global marketplace and choose from a much wider range of products.

    <html> <head> <title>JavaScript String charAt() Method</title> </head> <body> <script type="text/javascript">    var str = new String( "This is string" );    document.writeln("str.charAt(0) is:" + str.charAt(0));    document.writeln("<br />str.charAt(1) is:" + str.charAt(1));

    • Str.charAt(0) is:T

    • Str.charAt(0) is:i

    • Str.charAt(1) is:h

    • Str.charAt(1) is:s

    Correct Answer(s)
    A. Str.charAt(0) is:T
    A. Str.charAt(1) is:h
    Explanation
    The charAt() method is used to return the character at a specified index in a string. In this code snippet, the variable "str" is a string "This is string". The charAt(0) method is called on the string "str", which returns the character at index 0, which is "T". Similarly, the charAt(1) method is called on the string "str", which returns the character at index 1, which is "h". Therefore, the correct answer is "str.charAt(0) is:T ,str.charAt(1) is:h".

    <script type="text/javascript"> var visitorName = "Chuck"; var myOldString = "Hello username! I hope you enjoy your stay username."; var myNewString = myOldString.replace(/username/g, visitorName);   document.write("<br />New string = " + myNewString);

    Correct Answer(s)
    New string = Hello Chuck! I hope you enjoy your stay Chuck.
    Hello Chuck! I hope you enjoy your stay Chuck.
    Explanation
    The given code snippet uses the `replace()` function in JavaScript to replace all occurrences of the word "username" in the `myOldString` variable with the value of the `visitorName` variable, which is "Chuck". The `/username/g` is a regular expression pattern that matches all occurrences of "username" in the string. The resulting new string, stored in the `myNewString` variable, is then displayed using the `document.write()` function. The answer shows the new string after the replacement has been made, which is "Hello Chuck! I hope you enjoy your stay Chuck." repeated twice.

    <script type="text/javascript"> var aURL = "http://www.tizag.com/www.html"; var aPosition = aURL.indexOf("www");   document.write("The position of www  =  " + aPosition);

    • The position of www = 7

    • The position of www = 8

    • The position of www = 6

    • None of above

    Correct Answer
    A. The position of www = 7
    Explanation
    The correct answer is "The position of www = 7" because the indexOf() method in JavaScript returns the position of the first occurrence of the specified value within a string. In this case, the value "www" is found at index 7 in the string "http://www.tizag.com/www.html".

    Rate this question:

  • 16. 

    <script type="text/javascript"> var myRegExp = /Alex|John/; var string1 = "Today John went to the store and talked with Alex."; var matchPos1 = string1.search(myRegExp);   if(matchPos1 != -1)                document.write("There was a match at position " + matchPos1); else                document.write("There was no match in the first string");

    • There was no match in the first string

    • There was a match at position 6

    • There was a match at position 7

    • None of above

    Correct Answer
    A. There was a match at position 6
    Explanation
    The regular expression /Alex|John/ is used to search for either "Alex" or "John" in the given string. In this case, the string "Today John went to the store and talked with Alex." is searched. The matchPos1 variable stores the position of the first occurrence of a match. Since "John" is found at position 6 in the string, the condition matchPos1 != -1 is true and the message "There was a match at position 6" is displayed.

    The charCodeAt() method is used to return the Unicode value of the character at a specified index in a string. In this code snippet, the variable "str" is a string that says "This is string". The charCodeAt(0) method is used to get the Unicode value of the character at index 0, which is "T". The Unicode value of "T" is 84. Similarly, the charCodeAt(1) method is used to get the Unicode value of the character at index 1, which is "h". The Unicode value of "h" is 104.
