使用jQuery/JavaScript复制到剪贴板文本框值

第1步:改变你的copyToClipboard(element)喜好:

function copyToClipboard(text) {

   var textArea = document.createElement( "textarea" );
   textArea.value = text;
   document.body.appendChild( textArea );

   textArea.select();

   try {
      var successful = document.execCommand( 'copy' );
      var msg = successful ? 'successful' : 'unsuccessful';
      console.log('Copying text command was ' + msg);
   } catch (err) {
      console.log('Oops, unable to copy');
   }

   document.body.removeChild( textArea );
}

第2步:给你的按钮一个id,然后像这样添加一个事件监听器:

$( '#btnCopyToClipboard' ).click( function()
 {
     var clipboardText = "";

     clipboardText = $( '#txtKeyw' ).val();

     copyTextToClipboard( clipboardText );
     alert( "Copied to Clipboard" );
 });
