Js制作简单弹出层DIV在页面居中 中间显示遮罩的具体方法
人气:0
这两天要用到正好练练手,比想象中碰到的问题要多,比如:
ie6背景透明 ie6居中显示 还有对js对象的理解
openID=显示按钮,conID=需要显示的div,closeID=关闭按钮
解决了:
1.可以遮挡ie6下的select元素 但是在ie6下div没有透明度
2.弹出的div可以一直在浏览器屏幕中间显示
问题:
1.目前不支持.class 只支持#id
2.需要显示的div需要自己设置css
3.在ie6下需要设置css
例如div {_position: absolute;_top: expression(documentElement.scrollTop + 340 + "px"); }
4.ie6下背景div没有透明度 这里我上网搜到的结果都不能解决 如果您有方法请给我留言
