<!DOCTYPE html>
<html>
<body>
<button onclick="myFunction()">Copy text</button>
<script>
function myFunction() {
var copyText = "myText";
copyText.select();
document.execCommand("copy");
alert("Copied the text: " + copyText.value);
}
</script>
</body>
</html>
The reason it wasnt working is because you cant do to a varaible .select(); 它不起作用的原因是因为您不能对变量.select();进行操作。 so when you do a document.execCommand("copy");
因此,当您执行document.execCommand(“ copy”);时, your copying any other selected text try putting the stuff in a input box and then try .select();
您复制任何其他选定的文本时,请尝试将内容放入输入框,然后尝试.select();。
<!DOCTYPE html>

<body>
<input id="myId" value="myText"> </input>
<button onclick="myFunction()">Copy text</button>

var copyText = document.getElementById("myId");
copyText.select();
document.execCommand("copy");
alert("Copied the text: " + copyText.value);
}
</script>
