jQuery method: Implement the switching effect of the check box selected state

In web development, the use of check boxes is often involved. Sometimes we need to achieve the switching effect of the selected state of a check box when it is clicked. In this case, we can use jQuery to achieve this. This article will introduce how to use the jQuery method to achieve the switching effect of the selected state of the check box, and provide specific code examples.

First, we need to add a simple checkbox element to the HTML file, as shown below:

<input type="checkbox" id="myCheckbox"> 点我切换状态

Next, we introduce the jQuery library into the HTML file, which can be introduced through CDN ：

<script src="https://cdn.bootcdn.net/ajax/libs/jquery/3.6.0/jquery.min.js"></script>

Then, we write jQuery code to achieve the switching effect of the checked state of the check box. The code is as follows:

$(document).ready(function(){
    $("#myCheckbox").click(function(){
        if($(this).prop("checked")){
            $(this).attr("checked", false);
        } else {
            $(this).attr("checked", true);
        }
    });
});

The above code illustrates that when the check box element is clicked, jQuery is used to detect its current selected state. If it is selected, the selected state is removed; if it is not selected, the selected state is added. This achieves the switching effect of the selected state of the check box.

Finally, we add styles to the CSS file to set different style effects for the selected and unselected states:

/* 选中时的样式 */
input:checked {
    background-color: #00FF00;
}

/* 未选中时的样式 */
input {
    background-color: #FF0000;
}

Through the above steps, we successfully implemented the jQuery method to achieve complex effects. The switching effect of the selected state of the marquee. In this way, when users click on the check box, they will see an obvious switching effect between the selected and unselected states, which improves the user experience.
