when you click manually, you can copy the specified content to the pasteboard, and add an automatic loading page on this basis, how to achieve it?
< hr ><body>
<input type="text" id="inputText" value="444"/>
<input type="button" id="btn" value=""/>
<hr>
<textarea rows="4"></textarea>
<script type="text/javascript">
var btn = document.getElementById("btn");
btn.addEventListener("click", function(){
var inputText = document.getElementById("inputText");
var currentFocus = document.activeElement;
inputText.focus();
inputText.setSelectionRange(0, inputText.value.length);
document.execCommand("copy", true);
currentFocus.focus();
alert("");
});
</script>
<script type="text/javascript">
window.onload=function(){
var btn = document.getElementById("btn");
btn.click();
document.execCommand("copy", true);
}
</script>
</body>
