el.select(); // Select the <textarea> content
document.execCommand('copy'); // Copy - only works as a result of a user action (e.g. click events)
document.body.removeChild(el); // Remove the <textarea> element
if (selected) { // If a selection existed before copying
document.getSelection().removeAllRanges(); // Unselect everything on the HTML document

}
};

}
},上面是定义好的一个方法 不管在哪里 都是通用的
