jQuery 在 Flash 对象参数上替换？

Question

给定一个

<div id="dialog" style="display:none; width:100%; vertical-align:middle;">
    <object id="player" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" name="player" width="628" height="400">
        <param name="movie" value="../../help/videos/videoplayer.swf" />
        <param name="allowfullscreen" value="true" />
        <param name="allowscriptaccess" value="always" />
        <param name="flashvars" value="file=../../help/videos/video.flv" />
        <object type="application/x-shockwave-flash" data="../../help/videos/videoplayer.swf" width="628" height="400">
            <param name="movie" value="../../help/videos/videoplayer.swf" />
            <param name="allowfullscreen" value="true" />
            <param name="allowscriptaccess" value="always" />
            <param name="flashvars" value="file=../../help/videos/video.flv" />
        </object>
    </object>

为什么不会

$("#dialog").find('<param name="flashvars" value="file=../../help/videos/video.flv" />').replaceWith('<param name="flashvars" value="file=../../help/videos/myfile.flv" />');

工作？

您没有传递选择器来查找，您可以执行以下操作:

$('#player param[name=flashvars]').attr('value','new value');
