For long ago, flash needs to be introduced to access the clipboard by calling the flash api, Which is disgusting. Now, abyun does not recommend flash itself, so there is a natural way.

SCRIPT function CopyAll (T) {T. focus () T. select () if (document.all?therange=t.createtextrange(thertherange.exe cCommand ("Copy") // Copy} SCRIPT(Content test)(You can paste the content here)

He JavaScript document.exe cCommand ('copy') support has grown, see the links below for browser updates:

IE10 + (although this document indicates some support was there from IE5.5 + ).
Google Chrome 43 + (~ April 2015)
Mozilla Firefox 41 + (shipping ~ September 2015)
Opera 29 + (based on Chromium 42 ,~ April 2015)
Simple Example
Var copyTextareaBtn = document. querySelector ('. js-textareacopybtn ');

CopyTextareaBtn. addEventListener ('click', function (event ){
Var copyTextarea = document. querySelector ('. js-copytextarea ');
CopyTextarea. 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');

}
});
