有時候需要在網頁中某個div載入之后，動態引入一段javascript，IE下的解決方案：
| 以下為引用的內容： CODE: newjs. onreadystatechange = function ( ) { if (newjs. readyState == 'loaded' ) { // ready! } } newjs. onload = function ( ) { // ready! } |
主要利用了onload以及onreadystatechange事件。把這個加以利用，也能動態載入外部css。下面是同時適合Ie/firefox的寫法。
| 以下為引用的內容： 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; } |
