jquery判断是否选中单选按钮的问题，请前辈们给看看

HTML code

<form>性别<input type="radio" name="sex"> 男<input type="radio" name="sex"> 女爱好<input type="radio" name="enjoy">看书<input type="radio" name="enjoy">逛街<input type="radio" name="enjoy">运动政治面貌<input type="radio" name="zhengzhi">团员<input type="radio" name="zhengzhi">党员<input type="submit" value="提交"></form>

下面是我写的jquery,当所有选项都选中的时候，我才提交表单，有一项未选中都不能提交表单，请各位看看我哪错了.怎么修改，非常感谢

JScript code

function toSubmit(){    var s=true;    $(":radio").each(function(){                var radio = $(this).attr("name");                if($(":radio[name='"+radio+"']").attr("checked")==false)        {            s=false;        }                  })    if(s==false)    {        alert("所有项为必填！");    }        return s;
