How to use jQuery array to pop up window output

Apr 17, 2023 pm 03:01 PM

jQuery is a popular JavaScript library that makes it easier to quickly create interactive elements on web pages. In JavaScript, an array is a list of values ​​that makes it easy to process and manipulate data. In this article, we will discuss how to use jQuery arrays to generate pop-up output.

1. Create an array

In JavaScript, you can use array literals or array constructors to create arrays. For example:

var myArray = ["apple", "banana", "orange"];
Copy after login

or:

var myArray = new Array("apple", "banana", "orange");
Copy after login

When using jQuery, we can identify the array to be referenced and map it to a variable using an array literal. For example:

var fruits = ["apple", "banana", "orange"];
Copy after login

2. Use the alert pop-up window to output an array

Alert is a method of popping up a message box on a web page. To output an array using alert, you can use the join method in JavaScript to convert the array to a string. For example:

var fruits = ["apple", "banana", "orange"];
alert(fruits.join(", "));
Copy after login

This code will create a comma separated string containing the array elements and display them in a popup window.

3. Use console.log to output an array

Console.log is a method of outputting messages in the console window. To output an array in the console, you can use the forEach method in JavaScript to iterate over the array elements and print them out using the console.log method. For example:

var fruits = ["apple", "banana", "orange"];
fruits.forEach(function(item, index) {
  console.log(index + 1 + ". " + item);
});
Copy after login

This code will iterate over each element in the array and output its index and content.

4. Use jQuery plug-in pop-up window to output array

The jQuery plug-in is an extension that adds functions and effects to the jQuery library. There are many plugins available for popping up windows on web pages, such as Bootstrap Modal, jQuery UI Dialog, and SweetAlert2. Using these plugins, it is possible to output arrays in a beautiful window.

Taking Bootstrap Modal as an example, you can use the following code to output an array in the window:

var fruits = ["apple", "banana", "orange"];

var modalContent = "";
fruits.forEach(function(item, index) {
  modalContent += "

" + (index + 1) + ". " + item + "

"; }); $("#myModal .modal-body").html(modalContent); $("#myModal").modal("show");
Copy after login

This code will create an HTML code containing array elements and attach it to the modal window. in the content area. Finally, a modal window pops up to display the results.

Summary

This article discusses how to use array popup window output in jQuery. You can use the alert and console.log methods to output an array, or you can use a jQuery plugin to create a beautiful window and display the results in it. When working with data, arrays are a very useful data structure that can play a huge role when working with collections of data.
