A pure JavaScript solution for copying the contents of a textarea to the clipboard when the user clicks on the textarea:
当用户单击 textarea 时，将 textarea 的内容复制到剪贴板的纯 JavaScript 解决方案：
<script>
function copySelectionText(){
var copysuccess // var to check whether execCommand successfully executed
try{
copysuccess = document.execCommand("copy") // run command to copy selected text to clipboard
} catch(e){
copysuccess = false
}
return copysuccess
}
function copyfieldvalue(e, id){
var field = document.getElementById(id)
field.select()
var copysuccess = copySelectionText()
}
var bio = document.getElementById('mybio')
bio.addEventListener('mouseup', function(e){
copyfieldvalue(e, 'mybio')
var copysuccess = copySelectionText() // copy user selected text to clipboard
}, false)
</script>
Note:If you want to copy only parts of the textarea contents to clipboard, the tutorial Reading and copying selected text to clipboard using JavaScripthas more info on that.
注意：如果您只想将 textarea 内容的一部分复制到剪贴板，教程使用 JavaScript 读取和复制所选文本到剪贴板有更多信息。
