我有这个脚本使整个网站变灰,并在单击文本“showPopUp”时弹出一个对话框。我的问题是如何让这个脚本在页面加载时自动执行?
脚本:
<script type="text/javascript">
function showPopUp(el) {
var cvr = document.getElementById("cover")
var dlg = document.getElementById(el)
cvr.style.display = "block"
dlg.style.display = "block"
if(document.body.style.overflow = "hidden") {
cvr.style.width = "1024"
cvr.style.height = "100%"
}
}
function closePopUp(el) {
var cvr = document.getElementById("cover")
var dlg = document.getElementById(el)
cvr.style.display = "none"
dlg.style.display = "none"
document.body.style.overflowY = "scroll"
}
</script>
