}
function handle () {
var computedStyle = getComputedStyle(span, false);
var content = computedStyle.content;
console.log('content: %s', content);
var match = content.match(/[\w+=\/]+/);
// base64解码
if (match) {
try {
content = decodeURIComponent(escape(atob(match[0])));
} catch (ex) {
fn(ex);
return;
}
}
return content
}
