相信我，我和你一样讨厌这些。这是给客户的，所以我不能决定他们应该做什么:)
这是你如何使用它：
<script type="text/javascript">
var exitsplashmessage = 'Please dont go!';
var exitsplashpage = 'http://www.site.com/exitpage/';
</script>
<script type="text/javascript" src="/exit.js"></script>
问题是将其加载到 iframe 中，这并不是我真正想要做的。我只想让它重定向到用 exitsplashpage 定义的页面；
这是 exit.js 代码：
function addLoadEvent(func) {
var oldonload = window.onload;
if (typeof window.onload != 'function') {
window.onload = func;
} else {
window.onload = function () {
if (oldonload) {
oldonload();
}
func();
}
}
}
function addClickEvent(a, i, func) {
if (typeof a[i].onclick != 'function') {
a[i].onclick = func;
}
}
var theDiv = '<div id="ExitSplashDiv" style="display:block; width:100%; height:100%; position:absolute; background:#FFFFFF; margin-top:0px; margin-left:0px;" align="center">';
theDiv = theDiv + '<iframe src="' + exitsplashpage + '" width="100%" height="100%" align="middle" frameborder="0"></iframe>';
theDiv = theDiv + '</div>';
theBody = document.body;
if (!theBody) {
theBody = document.getElementById("body");
if (!theBody) {
theBody = document.getElementsByTagName("body")[0];
}
}
var PreventExitSplash = false;
function DisplayExitSplash() {
if (PreventExitSplash == false) {
window.scrollTo(0, 0);
PreventExitSplash = true;
divtag = document.createElement("div");
divtag.setAttribute("id", "ExitSplashMainOuterLayer");
divtag.style.position = "absolute";
divtag.style.width = "100%";
divtag.style.height = "100%";
divtag.style.zIndex = "99";
divtag.style.left = "0px";
divtag.style.top = "0px";
divtag.innerHTML = theDiv;
theBody.innerHTML = "";
theBody.topMargin = "0px";
theBody.rightMargin = "0px";
theBody.bottomMargin = "0px";
theBody.leftMargin = "0px";
theBody.style.overflow = "hidden";
theBody.appendChild(divtag);
return exitsplashmessage;
}
}
var a = document.getElementsByTagName('A');
for (var i = 0; i < a.length; i++) {
if (a[i].target !== '_blank') {
addClickEvent(a, i, function () {
PreventExitSplash = true;
});
} else {
addClickEvent(a, i, function () {
PreventExitSplash = false;
});
}
}
disablelinksfunc = function () {
var a = document.getElementsByTagName('A');
for (var i = 0; i < a.length; i++) {
if (a[i].target !== '_blank') {
addClickEvent(a, i, function () {
PreventExitSplash = true;
});
} else {
addClickEvent(a, i, function () {
PreventExitSplash = false;
});
}
}
}
addLoadEvent(disablelinksfunc);
disableformsfunc = function () {
var f = document.getElementsByTagName('FORM');
for (var i = 0; i < f.length; i++) {
if (!f[i].onclick) {
f[i].onclick = function () {
PreventExitSplash = true;
}
} else if (!f[i].onsubmit) {
f[i].onsubmit = function () {
PreventExitSplash = true;
}
}
}
}
addLoadEvent(disableformsfunc);
window.onbeforeunload = DisplayExitSplash;
