            <div id="sayi2">Sayı 2 :    <input type = "text" name="deger2"></div> 
            <div id="sonuc">Sonuç :     <input type = "text" name="cevap"></div>
            <div id="button"><input type="button" value="Hesapla" onclick="hesaplama()" /></div>
        </form>
  </body>
</html>

popup.js

function hesaplama()
{
var sayi1 = window.document.form.deger1.value;
var sayi2 = window.document.form.deger2.value;
var toplam = parseFloat(sayi1) + parseFloat(sayi2) ;
window.document.form.cevap.value = toplam; 
}

当我加载这个扩展时，我可以正常看到。但是当我填充 deger1 和 deger2 文本框并单击按钮时，函数不起作用，在 souc 文本框（结果文本框）中为空。我该如何解决？我是创建 chrome 扩展的新手。谢谢你的帮助。

你已经manifest_version : 2在你的清单中，所以请阅读它引入的变化......
http://code.google.com/chrome/extensions/manifestVersion.html
你进入了控制台Refused to execute inline event handler because of Content-Security-Policy，因为 onclick 事件处理程序在您的 html ( <input type="button" value="Hesapla" onclick="hesaplama()" />) 中。对于清单版本 2，这是不允许的，您需要从 js 代码而不是 html 中附加事件侦听器。
这是您的代码的工作版本....
