JavaScript is a common programming language that can be used for website creation and interaction design. Among them, click-to-hide is a relatively basic feature in JavaScript and a very practical function.

At the same time, add an ID name to the outer div of the element so that subsequent JavaScript code can find this element.
For example, add a div element with the ID "target" in the HTML page:
<div id="target">
<button onClick="hide()">隐藏</button>
</div>The second step is to create a JavaScript function. The function name can be defined by yourself, and the function of the function is Achieve click-to-hide effect.

For example, add a function named "hide" in JavaScript:
function hide() {
let target = document.getElementById("target");
target.style.display = "none";
}The third step is to add code that references JavaScript in the HTML page so that it can be loaded automatically when the page is loaded. JavaScript code. In this example, we need to add a script tag to the head of the HTML page and introduce the JavaScript file using the src attribute.
For example, the method of adding reference JavaScript code in an HTML page is as follows:
<head>
<script src="script.js"></script>
</head>The fourth step, save the HTML and JavaScript files, and open the HTML file in the browser, you can see Click to hide the effect.
To sum up, it takes four steps to implement the click-to-hide function: create an element in HTML and add an onClick attribute; create a function in JavaScript to achieve the click-to-hide effect; reference the JavaScript file in HTML ;Save the file and view the effect in your browser.
