众知目前国内不少浏览器都自称双核,一般是 IE(Trident)+Webkit。因为 webkit 急速的体验和对 HTML5 的支持,有些情况下开发者可能希望用户优先甚至只使用 webkit 内核渲染,比如通过 Meta 标签来指定。然而目前还没有任何一个公认的标准来实现。大多数用户根本分不清浏览器双核之间的区别。所以把决定权交给开发者,以此给用户带来更好的浏览体验,不失为一件好事。
在这方面360就做的不错,我们也建议其它浏览器厂商一起支持这个实现。让这个控制标签成为行业标准。
在360内核控制meta标签说明文档中就有详细说明
<html> <head> <meta name="renderer" content="webkit|ie-comp|ie-stand"> </head> <body> </body></html>
content的取值为webkit,ie-comp,ie-stand之一,区分大小写,分别代表用webkit内核,IE兼容内核,IE标准内核。
若页面需默认用极速核,增加标签:
若页面需默认用ie兼容内核,增加标签:
若页面需默认用ie标准内核,增加标签:
在实际使用中有人会发现已经添加 ,为什么浏览器有时还是以IE内核渲染?这应该是浏览器的缓存问题,如果关闭浏览器之前的内核是IE,那么第一次打开还是以IE内核渲染,但刷新一下就变为极速模式了(webkit内核)
在实际工作中我常常按如下设置
