  • 打开你的firefox


  • 输入:
    http://www.xidea.org

  • 打开firebug脚本输入窗口。


  • 贴上代码:
    引用
    var xhr = new XMLHttpRequest();
    var replaceMap = {};
    var list = "20ac 81 201a 192 201e 2026 2020 2021 2c6 2030 160 2039 152 8d 17d 8f 90 2018 2019 201c 201d 2022 2013 2014 2dc 2122 161 203a 153 9d 17e 178".split(" ")
    var i=32;
    while(i--){
        replaceMap[String.fromCharCode(parseInt(list[i],16))] = String.fromCharCode(0x80+i)
    }
    function replacer(c){
        return replaceMap[c];
    }

    xhr.open("get","http://www.xidea.org/project/jsi/images/logo.gif",false);
    xhr.overrideMimeType("text/html;charset=ISO-8859-1");
    xhr.send('');

    prompt('',"data:image/png;base64,"+btoa(String(xhr.responseText).replace(/[\u0100-\uffff]/g,replacer)));

    按下:control + Entry 执行代码。

  • 复制弹出的生成代码:

  • 不出意外,应该是这样的:

用JS对图片文件做base64处理,生成inline image string?
有什么用呢?

没什么用,就是验证一下js读取二进制数据的方法。

就是把个png换成二进制码罢了,以前也测试过用ajax读二进制文件,可以读出来,就是不知道读出来用来干吗
