Answer 1

//读文件
var fso, f1, ts;
var ForReading = 1;
fso = new ActiveXObject("Scripting.FileSystemObject");
ts = fso.OpenTextFile(document.all.attachFile.value/*此处为含全部路径的文件名*/, ForReading);
document.all.mailbdy.value=ts.ReadAll();
ts.Close();
//写文件
var title = document.getElementById("title").value;//文件名
var fso=new ActiveXObject("Scripting.FileSystemObject");
var f=fso.CreateTextFile("C://"+title+".nc",true); //可随意选择后缀名
f.write(document.getElementById("babala").value);
f.Close();
