DotopAlert prompts users to install the player code _ javascript tips-js tutorial

DotopAlert prompts you to install the player code, which is mostly used to promote certain players on the movie site.

The Code is as follows:

Var _ WName = 'dotopalert '; // window ID
Var _ Lastver = 1; // remote version number
Var _ Timespan = 1; // COOKIE time: hour
Var _ Alertimg = "http: // www. **. com/js/ads/alert.png"; // image address
Var _ WUrl = 'HTTP: // **. com/**. exe ';//
Function $ (id ){
Return "string" = typeof id? Document. getElementById (id): id;
};
Var dCookie = {}
DCookie. set = function (name, value, expiresd, path, domain, secure)
{
Var expdate = new Date ();
Var expires = arguments [2] | null;
Var path = arguments [3] | "/";
Var domain = arguments [4] | null;
Var secure = arguments [5] | false;
If (expires) expdate. setMinutes (expdate. getMinutes () + parseInt (expires ));
Var cookietemp = escape (name) + '=' + escape (value) + (expires? '; Expires =' + expdate. toGMTString (): '') + (path? '; Path =' + path: '') + (domain? '; Domain =' + domain: '') + (secure? '; Secure ':'');

}
DCookie. get = function (name)
{
Var arr, reg = new RegExp ("(^ |)" + name + "= ([^;] *) (; | $ )");
