在IE浏览器下，一次resize事件被执行了多次。这是IE6和IE7的一个比较广为认知的问题，这个问题在这两个版本的浏览器中表现有所不同，通常IE6下会比IE7下更为糟糕。
现在已经有了一个较好的解决方案，让jquery.wresize.js这个jquery插件来帮你：

( function( $ )
{
$.fn.wresize = function( f )
{
version = '1.1';
wresize = {fired: false, width: 0};
function resizeOnce()
{
if ( $.browser.msie )
{
if ( ! wresize.fired )
{
wresize.fired = true;
}
else
{
var version = parseInt( $.browser.version, 10 );
wresize.fired = false;
if ( version < 7 )
{
return false;
}
else if ( version == 7 )
{
//a vertical resize is fired once, an horizontal resize twice
var width = $( window ).width();
if ( width != wresize.width )
{
wresize.width = width;
return false;
}
}
}
}
return true;
}
function handleWResize( e )
{
if ( resizeOnce() )
{
return f.apply(this, [e]);
}
}
this.each( function()
{
if ( this == window )
{
$( this ).resize( handleWResize );
}
else
{
$( this ).resize( f );
}
} );
return this;
};
} ) ( jQuery );
如何使用，请看这个例子test page：
