我是一个开始的javascript程序员。我正在尝试创建类似于Lightbox 2的内容,但要简单得多。为什么我想从头开始做我自己的唯一原因是我可以学习。不过,我一直被困在显示图像的最后关键部分。我相信问题在于我尝试使用onclick将其赋值给匿名函数:elem [i] .onclick = function(){liteBoxFocus(imgSource,imgTitle);返回false;}; 。如果您运行我的代码并尝试点击Google徽标,它会显示yahoo徽标和标题,而不是谷歌的徽标和标题。但是,当你点击雅虎标志时,它可以正常工作,所以似乎匿名函数只适用于最后一个循环。提前致谢!!!javascript onclick,匿名函数
为了您的方便,我已将整个CSS/JS/XHTML放在一个页面中。
