表单遮住弹出层解决方法(select遮住DIV)

本文介绍了两种解决IE6浏览器下拉框遮挡弹出层的技术方案,包括隐藏和显示下拉框的JavaScript代码实现,以及通过iframe元素调整z-index层级关系的方法。

IE6中下拉框把弹出层遮住了,表单遮住弹出层解决方法(select遮住DIV),在IE6下,下拉框(select)会遮住弹出层 ,在IE6下,下拉框(select)会遮住弹出层,IE6下div不能将select框遮住
以上是相关的百度搜索,看来同样的问题很多人都遇到过,我也是!


解决方法


第一個解決辦法 :

在IE6下下拉框(select)会遮住弹出层,用样式办法暂时无法解决,包括z-index这个属性。

最变态的方法:

就是在层弹出的时候把下拉框给隐藏掉,用display:none属性或visable:hiddle属性;当层隐藏的时候再把下拉框给显示出来:

function hiddenselect()
{
    var f = document.forms["form1"];
    if (f)
    {
    for (i=0;i<f.elements.length;i++)
   {
   if (f.elements[i].type=="select-one")
   {
   f.elements[i].style.display="none";
   }
   }
   }
}

function showselect()
{
    var f = document.forms["form1"];
    if (f)
    {
    for (i=0;i<f.elements.length;i++)
   {
   if (f.elements[i].type=="select-one")
   {
   f.elements[i].style.display="";
   }
   }
   }
}


第二個解決辦法

select元素在ie中是属于一个特例,它和其他的html元素不同,从浏览器层面来解释,它实际上是一个窗体级别的元素(如果有做过c/s开发,应该会知道这点),所以它的优先级大大高于其他所有的html标签,只要有它在的地方,它就会从所有元素的背后冒出个头来,而只有同样窗体级的frame才能遮住它(废话,要是遮不住select,那这个东东不就从frame外冒出来?)

而微软为了解决这个问题,就给iframe(这个东东不是窗体级的哦!)增加了一个属性,让它能够遮住select(不然在一个iframe外诡异地出现一个select……成何体统),因此,iframe在ie中就附有了这个神圣的使命,遮住select,不让它随意地抛头露面。

而且,由于iframe本身并不是窗体级别的元素,所以只要设置z-index,就可以设置iframe在页面中的层次关系,利用这一点就可以很方便来遮住那个不怎么讨喜的select。代码如下:
