一段使用javascript保存文件的代码。这里方法可以保存指定id元素下的所有html内容；不过这个方法只支持IE浏览器。
function createHtml() {
try {
save_record("index1", $("#yhtcprediv").html());
} catch (e) {
alert(e);
}
}
function save_record(filename, content) {
//打开新窗口保存
var winRecord = window.open('about:blank', '_blank', 'top=500');
winRecord.document.open("text/html", "utf-8");
winRecord.document.write(" <div class=\"introBox section package boxBg02\" id=\"yhtcprediv\">" + content + "</div>");
winRecord.document.execCommand("SaveAs", true, filename + ".html");
winRecord.close();
}
