@H_404_0@本文实例讲述了jscript读写二进制文件的方法。分享给大家供大家参考。具体实现方法如下：

<div class="jb51code">
<pre class="brush:js;">
var bin = new Array(256);
for(var i=0;i<256;i++){
bin[i]=String.fromCharCode(i);
}
function TestWrite(){
var Stream = new ActiveXObject("ADODB.Stream");
var adTypeBinary=1,adTypeText=2;
Stream.Type = adTypeText;
Stream.CharSet = "iso-8859-1";
Stream.Open();
//Stream.WriteText("\x00\x01\x02\xff\xff");
for(var i=0;i<256;i++){
Stream.WriteText(String.fromCharCode(i));
//Stream.WriteText(bin[i]);
}
Stream.SaveToFile("c:\windows\temp\test.bin",2);
Stream.Close();
Stream = null;
}
function BinaryFile(filepath){
var adTypeBinary=1,adTypeText=2;
var adSaveCreateNotExist=1,adSaveCreateOverWrite=2;
var adReadAll=-1,adReadLine=-2;
this.path=filepath;
this.WriteAll = function(content){
var Stream = new ActiveXObject("ADODB.Stream");
Stream.Type = adTypeText;
Stream.CharSet = "iso-8859-1";
Stream.Open();
Stream.WriteText(content);
Stream.SaveToFile(this.path,adSaveCreateOverWrite);
Stream.Close();
Stream = null;
}
this.ReadAll = function(){
var Stream = new ActiveXObject("ADODB.Stream");
Stream.Type = adTypeText;
Stream.CharSet = "iso-8859-1";
Stream.Open();
Stream.LoadFromFile(this.path);
var content = Stream.ReadText(adReadAll);
Stream.Close();
Stream = null;
return content;
}
}
