今天有个需求,首次进入需要弹窗,然后就在网上找了下,虽然看了很多但是说的都不是我想要的,最后终于到了一个合适的。
function get_cookie(Name) { var search = Name + "="; var returnvalue = ""; if (document.cookie.length > 0) { offset = document.cookie.indexOf(search); if (offset != -1) { // if cookie exists offset += search.length; // set index of beginning of value end = document.cookie.indexOf(";", offset); // set index of end of cookie value if (end == -1) end = document.cookie.length; returnvalue=decodeURI(document.cookie.substring(offset, end)) } } return returnvalue; } setTimeout(function(){ if (get_cookie("popped")==""){ document.cookie="popped=yes"; alert('弹窗'); } },2000);
