How to jump to the web page and print in javascript

With the rapid development of the Internet, web page production is becoming more and more complex. JavaScript is required to implement some advanced operations, such as page jumps and printing functions.

In websites, we often need to use the jump function. For example, clicking a button on the page will jump to another page. This requires the use of the jump function in JavaScript.

The JavaScript jump function is very simple. You only need to use the location.href attribute to change the URL address of the current page to achieve the jump. The following is a sample code:

function jumpToPage(url) {
    location.href = url;
}

The above code definition A function named jumpToPage is created, which accepts a parameter url, which represents the URL address of the page that needs to be jumped to. When the user calls this function, the page will jump to the specified URL address.

For example, if we want to jump to Baidu's homepage, we can use the following code:

jumpToPage("https://www.baidu.com/");

In addition to using JavaScript to implement the jump function, we can also use hyperlinks to implement page jumps. Just use the <a> tag in HTML, for example:

<a href="https://www.baidu.com/">跳转到百度首页</a>

When the user clicks on this link, it will jump to the Baidu homepage.

In addition to page jumps, we also need to frequently use the printing function, such as printing out the content of the current page to facilitate users to save or share. JavaScript also provides functions to implement printing functions.

In JavaScript, we can use the print method of the window object to implement the printing function. The following is a sample code:

function printPage() {
    window.print();
}

The above code defines a function named printPage, which will print the contents of the current page when the function is called.

We can also add a print button to the page, allowing the user to click it to trigger the print operation. The code is as follows:

<button onclick="printPage()">打印</button>

When the user clicks the button, the page content will be printed.

In general, it is very simple to implement page jump and printing functions in JavaScript. You only need to master a few basic JS functions and properties to achieve it. In actual projects, we need to combine HTML, CSS, JavaScript and other technologies for development based on specific needs to continuously improve the user experience and interactivity of the page.
