我去，JS自执行匿名函数竟然有20几种写法！
小編覺(jué)得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.
為什么80%的碼農(nóng)都做不了架構(gòu)師？>>> ??
發(fā)現(xiàn)一個(gè)新的自執(zhí)行寫(xiě)法：{ var x; x=1; alert(x);} //2013-01-30 14:45:57 //五大類，20幾種寫(xiě)法//第一類 //最常見(jiàn)的一種 ( function(w) {alert(w.location.href+","+11); }(window));[ function(w) {alert(w.location.href+","+11); }(window) ];//第二類 ~ function(w) {alert(w.location.href+","+11); }(window);! function(w) {alert(w.location.href+","+11); }(window);+ function(w) {alert(w.location.href+","+11); }(window);- function(w) {alert(w.location.href+","+11); }(window);//第三類 delete function(w) {alert(w.location.href+","+11); }(window);typeof function(w) {alert(w.location.href+","+11); }(window);void function(w) {alert(w.location.href+","+11); }(window);new function(w) {alert(w.location.href+","+11); }(window);new function() {alert(window.location.href+","+11); }; //第四類 var f = function(w) {alert(w.location.href+","+11); }(window);//第五類 1, function() {alert(window.location.href+","+11); }();1 ^ function() {alert(window.location.href+","+11); }();1 > function() {alert(window.location.href+","+11); }();1 < function() {alert(window.location.href+","+11); }();1 / function() {alert(window.location.href+","+11); }();1 * function() {alert(window.location.href+","+11); }();1 | function() {alert(window.location.href+","+11); }();1 % function() {alert(window.location.href+","+11); }();1 & function() {alert(window.location.href+","+11); }();
