How to jump to a page in html? Tips sharing

HTML jump refers to the process of jumping from one web page link to another web page. It can also be a jump within the same page, such as jumping from the top to the bottom of an article. Let's take a look at the methods and techniques of HTML jump.

1. Hyperlink jump

Hyperlink is the most common way to jump in HTML. By adding the hyperlink tag in HTML, users can click Links jump to other web pages or other locations on the same page.

The syntax format of HTML hyperlink jump is as follows:

链接文本

Among them, "href" represents the target address of the link, which can be the URL of other web pages or the location ID within the same page.

1. Jump to other web pages

If you want to jump a link to other web pages, you only need to specify the URL of the target web page in the "href" attribute.

For example:

前往百度

Clicking the "Go to Baidu" link will jump to the Baidu homepage.

2. Jump to the internal anchor position of the same page

The method of adding anchor points in HTML documents allows users to jump by clicking on the link Go to another location on the same page.

The syntax format of HTML anchor is as follows:

跳转文本

Among them, the "id" attribute is the name of the anchor, which can be a string of English letters or numbers.

For example:

第一部分
第二部分
第三部分

The above code defines 3 anchor points, corresponding to different chapters in the document.

When we need to jump to a certain part of the document, we only need to specify the anchor name in the link.

For example:

跳转到第二部分

Click the "Jump to the second part" link, and the page will automatically slide to the second part.

2. JavaScript jump

In addition to hyperlinks, we can also use JavaScript code to implement page jumps. This method is more flexible and can achieve more complex jump requirements.

There are two methods for JavaScript jump. One is to use the location attribute of the window object to implement page redirection, and the other is to use the hyperlink onClick event to implement internal page jump.

1. window.location jump

window.location object contains the URL information of the current window. We can achieve page jumps and redirections by modifying its attribute values. .

In JavaScript, use the location.replace() method to achieve page jumps and redirections.

For example:

window.location.replace("http://www.baidu.com");

After executing the above code, the page will immediately jump to the Baidu homepage.

2. Hyperlink onClick event jump

In addition to using hyperlink jump, we can also add onclick events to hyperlinks and pass JavaScript in the event handler function Code to implement page jump.

For example:

前往百度

The onclick event in the above code sets the window.location.href property to the redirected URL and prevents the default link jump behavior by returning false.

3. HTML jump techniques

In addition to the jump methods introduced above, there are also some techniques that can make HTML jump more convenient and flexible.

1. Jump with parameters

Sometimes we need to bring some parameters when jumping to the page, such as search keywords, user ID, etc. At this time, we can use the URL Implemented in the form of parameters.

For example:

window.location.href="http://www.baidu.com/search?key=HTML";

In the above code, the search keyword "HTML" is used as the value of the URL parameter "key". When the page is redirected, it will jump to the Baidu search page and default Search for "HTML".

2. Jump timer

Sometimes we need to add a countdown to the page and jump to the page after the time is reached. At this time, we can use JavaScript timer accomplish.

For example:

var timer = setTimeout(function(){
    window.location.href = "http://www.baidu.com";
}, 5000);

The above code uses the setInterval method to jump to the Baidu homepage after 5 seconds.

4. Prevent repeated submissions

In operations such as form submission, sometimes users may submit multiple times quickly, which will cause unnecessary pressure on the server. , and even data anomalies may occur. To prevent repeated submissions, we can disable the submit button immediately after submitting the form, or use JavaScript to jump to the page.

For example:

    提交表单

In the above code, in the click event of the form submit button, the submit button is first disabled, and then the form submission operation is performed. After the form is submitted successfully, use window.location.href to jump to the Baidu homepage.
