How to use the reset method in jquery to clear the input box (code example)

JQuery is a JavaScript framework that has been widely used and popular. The framework makes working with JavaScript easy and provides powerful and flexible features, making the web development process more efficient.

During the development process, sometimes we need to clear the input box in the form after the form is submitted. At this time, you can use JQuery's reset method.

The JQuery reset method is a basic method for resetting a form, which can be easily referenced and used in JavaScript.

In order to use the JQuery reset method, you need to first obtain a reference to the form element to be reset, and then call the reset() method.

The following is an example:

<form id="myForm" method="post" action="submit.php">
    <input type="text" name="fullname" value="John Doe">
    <input type="text" name="email" value="johndoe@example.com">
    <input type="submit" value="Submit">
</form>

<button id="resetBtn">Reset Form</button>

<script>
    $(document).ready(function() {
        $("#resetBtn").click(function() {
            $("#myForm")[0].reset(); //使用reset方法清空表单
        });
    });
</script>

In the above example, we define a form that contains two input boxes fullname and email and a submit button. We also define a button resetBtn, whose click event will call the reset method to clear the form.

Before clicking the button, we also need to use JQuery's document.ready() method to ensure that the entire document has been loaded and ready for use.

Once the user clicks the "Reset" button, the JavaScript code above will clear the form by calling the reset() method.

Of course, the JQuery reset method also has some limitations. For example, if the form's values ​​are set dynamically through JavaScript code, the reset method will not reset those values ​​to their original state.

In short, the JQuery reset method is a very useful method. It can help us easily clear the form after the form submission is completed. It also has powerful and flexible functions, making the web development process simpler and more efficient.
