| var cssLink = document.createElement("link") | |
| cssLink.href = "top.css"; | |
| cssLink .rel = "stylesheet"; | |
| cssLink .type = "text/css"; | |
| frames['frame1'].document.body.appendChild(cssLink); | |
| } | |
| //load | |
| load() | |

| // 3.更改已有css TODO link obj必须存在的情况下是替换 | |
| frame1.document.getElementsByTagName("link")[0].href="top.css" | |
| // jquery | |
| var $head = $("iframe").contents().find("head"); | |
