RSS订阅有时候需要在网页中某个div载入之后，动态引入一段javascript，IE下的解决方案：
| 以下为引用的内容： CODE: newjs. onreadystatechange = function ( ) { if (newjs. readyState == 'loaded' ) { // ready! } } newjs. onload = function ( ) { // ready! } |
主要利用了onload以及onreadystatechange事件。把这个加以利用，也能动态载入外部css。下面是同时适合Ie/firefox的写法。
| 以下为引用的内容： CODE: var css; function include_css (css_file ) { var html_doc = document. getElementsByTagName ( 'head' ) [ 0 ]; css = document. createElement ( 'link' ); css. setAttribute ( 'rel', 'stylesheet' ); css. setAttribute ( 'type', 'text/css' ); css. setAttribute ( 'href', css_file ); html_doc. appendChild (css ); // alert state change css. onreadystatechange = function ( ) { if (css. readyState == 'complete' ) { alert ( 'CSS onreadystatechange fired' ); } } css. onload = function ( ) { alert ( 'CSS onload fired' ); } return false; } var js; function include_js (file ) { var html_doc = document. getElementsByTagName ( 'head' ) [ 0 ]; js = document. createElement ( 'script' ); js. setAttribute ( 'type', 'text/javascript' ); js. setAttribute ( 'src', file ); html_doc. appendChild (js ); js. onreadystatechange = function ( ) { if (js. readyState == 'complete' ) { alert ( 'JS onreadystate fired' ); } } js. onload = function ( ) { alert ( 'JS onload fired' ); } return false; } |
