本来应该是停留在这个界面 但是只是闪一下就消失了
这是代码
<script type="text/javascript">
function ShowBlock() {
var divNewBlock = document.getElementById('divNewBlock');
var divNewBlock_backgroud = document.getElementById('divNewBlock_backgroud');
divNewBlock_backgroud.style.width = document.body.scrollWidth + "px";
divNewBlock_backgroud.style.height = document.body.scrollHeight + "px";
divNewBlock_backgroud.style.display = "block";
divNewBlock.style.display = "block";
}
function HideBlock() {
var divNewBlock = document.getElementById('divNewBlock');
var divNewBlock_backgroud = document.getElementById('divNewBlock_backgroud');
divNewBlock_backgroud.style.display = "none";
divNewBlock.style.display = "none";
}
</script>
<style type="text/css">
