今天学习mvc3遇到了两个问题，

第一：“<add assembly="System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">”，经过搜索，原来必须要在webconfig的<assemblies>节中添加<add assembly="System.Data.Entity, Version=4.0.0.0, Culture=neutral,PublicKeyToken=b77a5c561934e089"></add>

第二：linq的连接串说是找不到了，原来是下面这段自动生成了Model层的app.config里，解决方法就是把它剪切到网站的webconfig中

<connectionStrings>

  <add name="SHOPEntities" connectionString="metadata=res://*/ShopEntity.csdl|res://*/ShopEntity.ssdl|res://*/ShopEntity.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=localhost;Initial Catalog=William.Shop;Integrated Security=True;MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient" />

 </connectionStrings>

看了一会js，innerHTML和innerText的区别可以从下面的代码中体现出来，

 function Test() {

            var countries = new Array();

            countries[0] = "China";

            countries[1] = "America";

            countries[2] = "England";

            var s = "";

            var div = document.getElementById("divArrayContent");

            for (var i = 0; i < countries.length; ++i) {

                s = s + countries[i] + "<br />";

                //document.write(countries[i] + "</br>");

            }

            //div.innerHTML = s;

            div.innerText = s;

        }
