Kindly share the solution for the Question #169775
In this assignment, let's build a Book Search page by applying the concepts we learned till now.
Instructions:
By following the above instructions, achieve the given functionality.
ask the user to enter three of their favourite television shows. once they have entered there shows,display the results. Use an array to store the three favourite television shows.
what do you wish to calculate:
area perimeter
enter values ______ submit<----button
the page allows the user calculate area or perimeter of a parallelogram. First user will select an option, then enters necessary parameters separated by comma. write a JavaScript function called shapeFormulas(0 to calculate and display area or perimeter in an alert.
the function should display an error if user does not follow the required input format.
Area : base x height
perimeter : 2 x (side1+side2)
example one
user select area
input:5,10
output: the area is : 50
example two
user select perimeter
input:5,10
output:the perimeter is:30
example three
user select Area
input: 2 3
output: Invalid parameters
Consider the following HTML page:
<html><head></head>
<body>
<form id="form1" name="form1" method="post" action="">
Enter a value
<label for ="txtString"></label>
<input type="text" name="txtString" id="txtString"/>
<input type="submit" name="button" id="button" value="Submit"/>
</form></body></html>
Assume that the page accept a string .Write a JavaScript function called printString() to to display every other word in a new line.the output will be displayed as an alert.

Book Search
In this assignment, let's build a Book Search page by applying the concepts we learned till now. .When a value is entered in the HTML input element with id searchInput and press on Enter key, Get title, imageLink, author (HTTP response with key search_results) by making HTTP request using fetch with URL https://apis.ccbp.in/book-store?title=kalam&maxResults=30, Set imageLink in the HTML img element and set author in the HTML paragraph element, When a value is entered in the HTML input element with id searchInput and an option is selected in the drop down, Make a HTTP GET request to fetch the books based on the title entered and maximum number of results, If search results not equal to zero, then append the search results to the HTML container element with id searchResults, If search results equal to zero, thendisplay"Noresultsfound".
Develop User Interface as mentioned below as per the requirements:
Button One: Activate Button Two: Deactivate
Button One is pressed two fields and a button appear
Field 1: From Number Field 2: To Number
Button: Activate
Field 1 should auto-populate with the number queried from DB. And should not be changeable. The reason to still have a field is just to make it explicit what is happening.
When the Activate Button is pressed execute some action with parameter as below.
CALLACTION = "Call Forwarding On"
PHONENUMBER = From Number (From Field 1)
TOLLNUMBER = To Number (From Field 2)
Button Two is pressed a prompt and two buttons appear.
Prompt: "Are you sure you would like to deactivate the <Telephone Number>?" Where <Telephone Number> is the number initially queried.
Button 1: Yes Button 2: No
