【记录】JS 获取图片原始尺寸－防止图片溢出

示例代码：

<div id="div_content">
    <img src="http://static.cnblogs.com/images/logo_small.gif" alt="Alternate Text" />
</div>

<script type="text/javascript">
    $(document).ready(function () {
        var myimg;
        var maxwidth = 643;
        $("#div_content img").load(function () {
            for (i = 0; i < $(this).length; i++) {
                myimg = $(this)[i];
                if (myimg.width > maxwidth) {
                    myimg.width = maxwidth;
                }
            }
        });
    });
</script>
