Question

我制作了一个按钮，在悬停时显示文字，但我想在用户点击按钮后显示文本，并在用户再次点击按钮后消失。代码基本上是一个按钮和文本，在设置为.80不透明度的黑框中显示“HELLO”。有什么建议吗？

Answer 1

当我理解你的问题是正确的时，你需要一个按钮，当用户点击它时悬停是不同的？

你可以通过在按钮上添加一个类来处理点击的CSS。

$('button').on('click', function () {
     $(this).addClass('clicked');
});

和css

button { background: red; }
button:hover { background: green; }
button.clicked { background: orange; }
button.clicked:hover { background: black; }

Answer 2

使用innerText和innerHTML 在检查代码时，您似乎使用了一些WISIWYG工具。

你问题上的标签只显示了javascript和html，css（你真正的工作环境），所以我假设这是用javascript和html，css。

以下是您可以复制和测试的代码段

<!doctype html>
<head>
<script>
function changeButtonText(el){
 if (el.value == "HELLO")
   el.value = "GOOD BYE";
 else el.value="HELLO";

 el = document.getElementById("concerned_ptag");
 if (el.innerText == "HELLO")
   el.innerText = "GOOD BYE";
 else el.innerText="HELLO";
}
</script>
</head>
<body>
<p id="concerned_ptag">
HELLO
</p>
<input type="button" value ="HELLO" id="concerned_button" onclick="changeButtonText(this);">
</body>
</html>

为p标签设计样式对您来说更容易。否则，再次ping。

Answer 3

当用户点击按钮时，会出现文字，再次点击时，会消失吗？

$(document).ready(function(){
    $('.bt').click(function(){
        $(this).find('span').fadeToggle();
    });
});

<a class="bt"><span>Button Text</span></a>
