jquery pop-up modification window

In web development, pop-up modification windows are a common functional requirement. This functionality can be easily achieved using jQuery. This article will introduce how to use jQuery to implement a pop-up modification window.

1. HTML structure

First, we need to create an HTML structure to describe the appearance and elements of the pop-up window. Generally speaking, a popup window should contain a title, form, submit button, and close button. The following is a simple HTML structure example:

<div id="modify-popup">
    <div class="popup-content">
        <h2>修改信息</h2>
        <form>
            <label>名称：</label>
            <input type="text" name="name" />
            <br/><br/>
            <label>年龄：</label>
            <input type="text" name="age" />
            <br/><br/>
            <input type="submit" value="提交" />
        </form>
        <a class="close" href="#">关闭</a>
    </div>
</div>

2. CSS Style

Next, we need to set the CSS style to make the pop-up window look beautiful. The following is a basic CSS example:

#modify-popup {
    position: fixed;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    background-color: rgba(0, 0, 0, 0.8);
    z-index: 9999;
    display: none;
    transition: opacity 0.3s ease-in-out;
}

.popup-content {
    background-color: #fff;
    width: 600px;
    height: 350px;
    margin: 10% auto;
    padding: 20px;
    border-radius: 10px;
    text-align: center;
    position: relative;
    overflow: auto;
}

.popup-content h2 {
    font-size: 32px;
}

.popup-content form label {
    font-size: 22px;
}

.popup-content form input[type="text"] {
    width: 90%;
    height: 30px;
    font-size: 20px;
    padding: 5px;
    margin-bottom: 10px;
    border-radius: 5px;
    border: 1px solid #ccc;
}

.popup-content form input[type="submit"] {
    width: 40%;
    height: 40px;
    font-size: 22px;
    background-color: #0066cc;
    color: #fff;
    border-radius: 5px;
    border: none;
    margin-bottom: 20px;
}

.popup-content .close {
    position: absolute;
    top: 15px;
    right: 15px;
    font-size: 22px;
}

3. jQuery code

Now that we have prepared the HTML and CSS code, the next step is to implement the jQuery code for the pop-up window. First, we need to bind a click event to the open button of the pop-up window:

$('#open-popup').click(function() {
    $('#modify-popup').fadeIn();
});

Then we need to bind a click event to the close button:

$('#modify-popup .close').click(function() {
    $('#modify-popup').fadeOut();
});

Finally, we need to bind a click event to the submit button Define a click event to handle the form submission operation:

$('#modify-popup form').submit(function(event) {
    event.preventDefault(); // 禁止表单提交
    // 处理表单提交逻辑
    $('#modify-popup').fadeOut();
});

4. Complete sample code

The following is the complete sample code:

HTML code:

打开弹出窗口
<div id="modify-popup">
    <div class="popup-content">
        <h2>修改信息</h2>
        <form>
            <label>名称：</label>
            <input type="text" name="name" />
            <br/><br/>
            <label>年龄：</label>
            <input type="text" name="age" />
            <br/><br/>
            <input type="submit" value="提交" />
        </form>
        <a class="close" href="#">关闭</a>
    </div>
</div>

CSS code:

#modify-popup {
    position: fixed;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    background-color: rgba(0, 0, 0, 0.8);
    z-index: 9999;
    display: none;
    transition: opacity 0.3s ease-in-out;
}

.popup-content {
    background-color: #fff;
    width: 600px;
    height: 350px;
    margin: 10% auto;
    padding: 20px;
    border-radius: 10px;
    text-align: center;
    position: relative;
    overflow: auto;
}

.popup-content h2 {
    font-size: 32px;
}

.popup-content form label {
    font-size: 22px;
}

.popup-content form input[type="text"] {
    width: 90%;
    height: 30px;
    font-size: 20px;
    padding: 5px;
    margin-bottom: 10px;
    border-radius: 5px;
    border: 1px solid #ccc;
}

.popup-content form input[type="submit"] {
    width: 40%;
    height: 40px;
    font-size: 22px;
    background-color: #0066cc;
    color: #fff;
    border-radius: 5px;
    border: none;
    margin-bottom: 20px;
}

.popup-content .close {
    position: absolute;
    top: 15px;
    right: 15px;
    font-size: 22px;
}

jQuery code:

$('#open-popup').click(function() {
    $('#modify-popup').fadeIn();
});

$('#modify-popup .close').click(function() {
    $('#modify-popup').fadeOut();
});

$('#modify-popup form').submit(function(event) {
    event.preventDefault(); // 禁止表单提交
    // 处理表单提交逻辑
    $('#modify-popup').fadeOut();
});

With the above code, we can easily realize the pop-up modification window function. In actual development, we can modify and optimize the layout, style and logic of the pop-up window as needed.
