修复了在IE中定位广告的问题

Question

可以跳到编辑以获取更新的说明.

我似乎无法设置一个通过document.write()固定位置写出来的广告.除了IE之外,它在所有其他浏览器中都能正常工作,包括IE9.

这是一个例子:http://htinteractive.com/bottom_bar/demo.html

任何建议都将受到高度赞赏.我的想法已经不多了.

谢谢.

我把问题缩小到我正在使用的以下IE问题.为了简化它......

<style type="text/css">
    #temp1
    {
        position:fixed; 
        bottom:0; 
        height:100px; 
        width:100px; 
        border:solid 2px red;
    }
</style>

<!--WORKS IN IE-->
<div id="temp1">
    <script type="text/javascript">
        document.write("<scr" + "ipt type=\"text/javascript\">\nif(typeof(cachebuster) == \"undefined\"){var cachebuster = Math.floor(Math.random()*10000000000)}\nif(typeof(dcopt) == \"undefined\"){var dcopt = \"dcopt=ist;\"} else {var dcopt = \"\"}\nif(typeof(tile) == \"undefined\"){var tile = 1} else {tile++}\ndocument.write('<scr'+'ipt src=\"http://ad.doubleclick.net/adj/shz.bloomington/home;pos=728x90_1;' + dcopt + ';tile=' + tile + ';sz=728x90;ord=' + cachebuster + '?\"></scr'+'ipt>');\n</scr" + "ipt>");
    </script>
</div>


<!--FAILS TO FIX POSITION IN IE-->
<script type="text/javascript">
    document.write('<div id="temp1">');
    document.write("<scr" + "ipt type=\"text/javascript\">\nif(typeof(cachebuster) == \"undefined\"){var cachebuster = Math.floor(Math.random()*10000000000)}\nif(typeof(dcopt) == \"undefined\"){var dcopt = \"dcopt=ist;\"} else {var dcopt = \"\"}\nif(typeof(tile) == \"undefined\"){var tile = 1} else {tile++}\ndocument.write('<scr'+'ipt src=\"http://ad.doubleclick.net/adj/shz.bloomington/home;pos=728x90_1;' + dcopt + ';tile=' + tile + ';sz=728x90;ord=' + cachebuster + '?\"></scr'+'ipt>');\n</scr" + "ipt>");
    document.write('</div>')
</script>

无论如何,我真的需要第二种方法来工作,而我正在试着弄清楚我的头发是怎样的.

谢谢.

未经测试，但似乎应该有效：

<script>
(function(){
  var w = window,
    d = document,
    s = d.createElement('script'),
    div = d.createElement('div'),
    el = [].slice.call(d.getElementsByTagName('script'), -1),
    baseUrl = 'http://ad.doubleclick.net/adj/shz.bloomington/home;pos=728x90_1;';
  // end var block

  if(!("cachebuster" in w)){
    cachebuster = Math.floor(Math.random()*10000000000);
  }
  dcopt = "dcopt" in w ? "" : "dcopt=ist;";
  tile = "tile" in w ? tile+1 : 1;

  div.id = 'temp1';
  div.appendChild(s);
  el.parentNode.inserBefore(div, el);
  s.src = baseUrl + dcopt + ';tile=' + tile + ';sz=728x90;ord=' + cachebuster + '?';

})();
</script>
