javascript - 求教一個js拷貝文本的問題

就是簡單的點擊拷貝，好像很多網站都有複製代碼這個按鈕。但是好像說很多瀏覽器不支援，要用flash，現在這個問題一般都是怎麼解決的

long ago都是需要引入flash通過調用flash的api訪問clipboard的，巨噁心..既然現在abobe自己都不推薦flash了,自然有辦法。

depende on Selection and document.execCommand API

(內容測試)(你可以在這裡粘帖內容)

he JavaScript document.execCommand('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');

}
});
