// 可行
if (window.frames.length != parent.frames.length) {
console.log('在iframe中111');
}

if (self.frameElement && self.frameElement.tagName == "IFRAME") {
console.log('在iframe中222');
}
// 可行
if (self != top) {
console.log('在iframe中333');
}

// if (top.location != location) {
// top.location.href = location.href;
// }
// if (self != top) {
// top.location.href = self.location.href;
// }
if (top != self) {
