我需要一些关于此的帮助，我想知道当用户仅单击页面上的任意位置一次时如何打开新选项卡。这是给我的博主的。我有这个代码:
<script type="text/javascript">
var popup = function() {
window.open ("http://example.com", "Window","status=1,toolbar=1,width=500,height=300,resizable=yes");
}
</script>
<body onclick="popup()">
<h1>Click anywhere!</h1>
</body>但是不起作用，因为每次点击都会打开一个新选项卡，我用 cookies 尝试了此代码
<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
var expDays = 1; // number of days the cookie should last
var page = "only-popup-once.html";
var windowprops = "width=300,height=200,location=no,toolbar=no,menubar=no,scrollbars=no,resizable=yes";
function GetCookie (name) {
var arg = name + "=";
var alen = arg.length;
var clen = document.cookie.length;
var i = 0;
while (i < clen) {
var j = i + alen;
if (document.cookie.substring(i, j) == arg)
return getCookieVal (j);
i = document.cookie.indexOf(" ", i) + 1;
if (i == 0) break;
}
return null;
}
function SetCookie (name, value) {
var argv = SetCookie.arguments;
var argc = SetCookie.arguments.length;
var expires = (argc > 2) ? argv[2] : null;
var path = (argc > 3) ? argv[3] : null;
var domain = (argc > 4) ? argv[4] : null;
var secure = (argc > 5) ? argv[5] : false;
document.cookie = name + "=" + escape (value) +
((expires == null) ? "" : ("; expires=" + expires.toGMTString())) +
((path == null) ? "" : ("; path=" + path)) +
((domain == null) ? "" : ("; domain=" + domain)) +
((secure == true) ? "; secure" : "");
}
function DeleteCookie (name) {
var exp = new Date();
exp.setTime (exp.getTime() - 1);
var cval = GetCookie (name);
document.cookie = name + "=" + cval + "; expires=" + exp.toGMTString();
}
var exp = new Date();
exp.setTime(exp.getTime() + (expDays*24*60*60*1000));
function amt(){
var count = GetCookie('count')
if(count == null) {
SetCookie('count','1')
return 1
}
else {
var newcount = parseInt(count) + 1;
DeleteCookie('count')
SetCookie('count',newcount,exp)
return count
}
}
function getCookieVal(offset) {
var endstr = document.cookie.indexOf (";", offset);
if (endstr == -1)
endstr = document.cookie.length;
return unescape(document.cookie.substring(offset, endstr));
}
function checkCount() {
var count = GetCookie('count');
if (count == null) {
count=1;
SetCookie('count', count, exp);
window.open(page, "", windowprops);
}
else {
count++;
SetCookie('count', count, exp);
}
}
// End -->
</script>但是不起作用，因为浏览器阻止了弹出窗口。
某些网站(例如 powvideo 或 Animeflv)有一个脚本，当用户单击任意位置时，会自动打开一个新选项卡，例如 data:text/html;base64,XXXXX
谢谢。
最佳答案
您只需要一个标志，可以检查它是否仍然可以打开弹出窗口。
var openPage = true;
function popup() {
if(openPage){
window.open ("http://example.com","Window","status=1,toolbar=1,width=500,height=300,resizable=yes");
openPage = false;
}
}<body onclick="popup()">
<h1>Click anywhere!</h1>
