Go language (Golang) is a simple, efficient and reliable programming language, especially suitable for web application development. HTML (Hypertext Markup Language) is a standard markup language used to create web pages. In the Go language, we can easily jump to an HTML page, and this article will introduce how to achieve it.

First, we need to use Go’s built-in web server. In Go 1.11 and above, you can use go modules to create web applications. We can add a file called go.mod in the project directory and add the following code in it:

module mywebapp

go 1.11

Then, we can create a main.gofile to write our web application. In this file, we need to import the net/http package and the html/template package:

package main

import (
    "html/template"
    "net/http"
)

Now, we can define a file called rootHandlerHttp handler function. In this function, we can use the html/template package to render the HTML template to be able to display the desired content in the browser:

func rootHandler(w http.ResponseWriter, r *http.Request) {
    tpl, _ := template.ParseFiles("home.html")
    tpl.Execute(w, nil)
}

In the above example, we use The template.ParseFiles function to parse an HTML template named home.html and render it to the http.ResponseWriter# using the tpl.Execute function ##middle.

Next, we need to define a route. A route is a map that links URLs to handler functions. We can use the

http.HandleFunc function to define routes:

func main() {
    http.HandleFunc("/", rootHandler)
    http.ListenAndServe(":8080", nil)
}
In the above example, we define a route that maps the root URL to the

rootHandler function handler program. The http.ListenAndServe function starts the built-in web server and binds it to port 8080.

After completing the above steps, we can create an HTML file named

home.html for displaying content in a web browser. We can use HTML markup language to define the content of this page:

<!DOCTYPE html>
<html>
<head>
    <title>My Web App</title>
</head>
<body>
    <h1>Welcome to My Web App</h1>
    <p>This is an example of how to jump to another HTML file.</p>
    <a href="/contact">Contact Us</a>
</body>
</html>
In the above HTML code, we use the

tag to create a hyperlink that points to URL/contact. This will trigger the route we defined and map the URL to the relevant handler function.

Finally, we need to create another HTML file called

contact.html that will be loaded when the user clicks on the hyperlink:

<!DOCTYPE html>
<html>
<head>
    <title>Contact Us</title>
</head>
<body>
    <h1>Contact Us</h1>
    <p>Feel free to contact us at any time.</p>
</body>
</html>
In this example , the

contact.html file only contains some simple text. In real applications, you can use any HTML tag to create rich, beautiful pages.

Through the above steps, we have successfully implemented the function of jumping to HTML pages using Go language. We can use similar principles to create more complex web applications, such as mapping URLs to database queries or other API calls.

In short, the Go language provides a simple and powerful way to create web applications, including jumping to HTML pages. On your next web development project, try using Go to build efficient and reliable applications.
