jquery adds jump path

jQuery is a very popular JavaScript library that can make JavaScript more concise and convenient. In web development, jump is a common behavior. When using jQuery, adding a jump path is a very simple operation.

First, add a link element in the HTML, for example:

<a href="#" id="myLink">点击跳转</a>

This is a simple link element with its href attribute set to "#" because we need a valid but empty href value. We also give it an id attribute so we can use it in jQuery.

Next, we need to write a jQuery code block to perform a jump action when the link is clicked:

$(document).ready(function() {
    $('#myLink').click(function(e) {
        e.preventDefault(); // 禁用默认链接行为
        window.location.href = 'https://www.example.com'; // 执行跳转
    });
});

In this code, first use $(document).ready( ) function ensures that the entire document has been loaded before executing the code. Then, use the click() function to bind the click event to the link element. In the click event, we use the e.preventDefault() function to disable the default link behavior so that we can perform the jump ourselves. Finally, we use the window.location.href property to jump the browser to the specified URL.

You can add different jump paths according to your own needs, for example:

window.location.href = 'https://www.example.com/page1.html';

or:

window.location.href = 'https://www.example.com/page2.html#section2';

In more complex web applications, you may need to Perform other operations before transferring. In this case, you can use jQuery's ajax() function.

For example, if you want to send a POST request to the server before jumping:

$(document).ready(function() {
    $('#myLink').click(function(e) {
        e.preventDefault(); // 禁用默认链接行为
        $.ajax({
            type: 'POST',
            url: 'https://www.example.com/myscript.php',
            data: {
                name: 'John',
                email: 'john@example.com'
            },
            success: function(response) {
                // 服务器响应成功后执行跳转
                window.location.href = 'https://www.example.com';
            }
        });
    });
});

In this example, we use the ajax() function in the click event to send a POST request to the server, Then execute the jump after the server responds successfully. In the ajax() function, we specify the request type, URL, POST data and success callback function.

In actual development, adding a jump path is a very common operation. When using jQuery, this operation is very easy to use and can be done in a few lines of code. If you want to learn more about jQuery, check out the jQuery official documentation.
