如何将按钮更改为而不是将div从可见更改为不可见，以做相反的事情？

Question

I have a button that changes the visibility of a div. It turns it from being visible to hidden and then back every time it's pressed. How can I make the div stay hidden and make the button show it when it's pressed.

 <script> function Hide() { var x = document.getElementById("box"); if (x.style.display === "none") { x.style.display = "block"; } else { x.style.display = "none"; } } </script> <button id="Hidden" onclick="Hide()">Click me</button> <div id="box"> Sample text. </div> 

Answer 1

将样式添加到div- <div id="box" style ="display: none;">...</div>

Answer 2

CSS - #box{display: none} //this will keep the element hidden on page load

function toggle() {
    var state = document.getElementById("box").style.display;
    if (state === "none") {
        state = "block";
    } else {
        state = "none";
    }
} 

<button id="Hidden" onclick="toggle()">Click me</button>
<div id="box"> 
 Sample text.
 </div>

You can also add <script> tag at the end of the HTML code with calling the Hide() func Like this:

 <script> function Hide() { var x = document.getElementById("box"); if (x.style.display === "none") { x.style.display = "block"; } else { x.style.display = "none"; } } </script> <button id="Hidden" onclick="Hide()">Click me</button> <div id="box"> Sample text. </div> <script>Hide();</script> 

Answer 4

you can also add the inline display none as below

 <script> function Hide() { var x = document.getElementById("box"); if (x.style.display === "none") { x.style.display = "block"; } else { x.style.display = "none"; } } </script> <button id="Hidden" onclick="Hide()">Click me</button> <div id="box" style="display:none"> Sample text. </div>
