var iframe = document.createElement("iframe");
iframe.src = "http://www.manongjc.com";
if (!/*@cc_on!@*/0) { //if not IE
iframe.onload = function(){
alert("Local iframe is now loaded.");
};
} else {
iframe.onreadystatechange = function(){
if (iframe.readyState == "complete"){
alert("Local iframe is now loaded.");
}
};
}
document.body.appendChild(iframe); 最近, nicholas c. zakas 文章《iframes, onload, and document.domain》的评论中 christopher 提供了一个新的判断方法(很完美):
var iframe = document.createElement("iframe");
iframe.src = "http://manongjc.com";
if (iframe.attachEvent){
iframe.attachEvent("onload", function(){
alert("Local iframe is now loaded.");
});
} else {
iframe.onload = function(){
alert("Local iframe is now loaded.");
};
}
document.body.appendChild(iframe);
几点补充说明:
每个人都需要一台速度更快、更稳定的 PC。随着时间的推移,垃圾文件、旧注册表数据和不必要的后台进程会占用资源并降低性能。幸运的是,许多工具可以让 Windows 保持平稳运行。
