判断ifame 是否加载成功

 有的时候，需要临时判断是否加载成功和成功以后的操作。
  
 1     var ifame = document.getElementById("mapHostel");
 2             if (ifame.attachEvent) {
 3                 ifame.attachEvent("onreadystatechange", function () {
 4                     if (ifame.readyState === "complete" || ifame.readyState == "loaded") {
 5                         alert("Local iframe is now loaded.");
 6                         ifame.detachEvent("onreadystatechange", arguments.callee);
 7 
 8                     }
 9 
10                 });
11             } else {
12                 ifame.onload = function () {
13                     alert("Local iframe is now loaded.");
14                 };
15             }
16             ifame.src = "/map/hostelMap.html";
