JAVASCRIPT Code

let myFormEl = document.getElementById("myForm");

let nameEl = document.getElementById("name");

let nameErrMsgEl = document.getElementById("nameErrMsg");

let passwordEl = document.getElementById("password");

let passwordErrMsgEl = document.getElementById("passwordErrMsg");

let resultErrMsgEl = document.getElementById("resultMsg");

nameEl.addEventListener("blur", function(event) {

  if (event.target.value === "") {

    nameErrMsgEl.textContent = "Required*";

  } else {

HTTP Requests & Responses

Background Image:

https://assets.ccbp.in/frontend/dynamic-webapps/book-search-bg.png

Books URL: https://apis.ccbp.in/book-store

Example:

https://apis.ccbp.in/book-store?title=IndiaQuery ParameterValuetitleValue of the searchInput element. Example: India

Method: GET

It should pass test conditions:

When a value is provided in the HTML input element with id searchInput and Enter Key is pressed, an HTTP GET request should be made to the Books URL with the query parameter 'title' as the value of the searchInput element

When the HTTP GET request is successful, then the searchResults element should consist of HTML image elements with src attribute value as the value of key 'imageLink' and HTML paragraph elements with text content as the value of key 'author' from HTTP response

Library Management

In this assignment, let's build a Library Management page by applying the concepts we learned till now.

Product of array Items

given an array integers,write JS program to get the product of the integers in the given array.

input

the input will be containing single line integers.

output

the output should be single line containing the product as shown in sample outputs.

input1

[1,2,3]

output1

[1 * 2 * 3 = 6]

input2

[-1, -2, -3]

output2

[-1*-2*-3 = -6]

Note: The Output should be displayed as [1 * 2 * 3 = 6]

"use strict";

process.stdin.resume();

process.stdin.setEncoding("utf-8");

let inputString = "";

let currentLine = 0;

process.stdin.on("data", (inputStdin) => {

 inputString += inputStdin;

});

process.stdin.on("end", (_) => {

 inputString = inputString

  .trim()

  .split("\n")

  .map((str) => str.trim());

 main();

});

function readLine() {

 return inputString[currentLine++];

}

function main() {

 let integers = JSON.parse(readLine());

 /* Please do not modify anything above this line */

 /* Write your code here and log the output */

}

1. Test cases:
2. when the HTML input element with id name lost the focus, if the value of HTML input element with id name is empty, then the text content in the HTML paragraph element with id name ErrMsg should have the error message otherwise it was an empty string
3. when the HTML input element with id password lost the focus, if the value of HTML input element with id password empty, then the text content in the HTML paragraph element with id name passwordErrMsg should have the error message otherwise it was an empty string
4. when the HTML button element with attribute type submit is clicked, if the values of the HTML input elements with ids name and password are not empty then the text content in HTML paragraph element with id resultMsg should be displayer "Login Success"
