1.使用场景描述:

页面中的循环体中存在view,且该view非静态内容,需要根据循环体中的变量,现实对应的数据库信息;

2.具体操作:(以视频中案例进行讲解)：

1) 主体数据构造及view数据初始化;

    说明: 由于view存在于主体数据的循环体中,所以需要在主体的循环体中初始化view数据内容;

     a,根据具体的实际情况,明确view页面所用到的所有变量;(案例中为: yhm)

     b,在主体数据中构造view用到的变量"yhm";

     案例截图说明:

    2)主体页面中的view绑定

          说明: 将view所需的参数,及view信息的定位参数传递给view

          a,对view进行属性绑定;绑定属性"data--url" 案例绑定说明: {"data--url":"/v/v1.html?id="+_id()+"&pathstr=user["+$index()+"]"}

              a.1 id 和pathstr 为传参变量,可进行自定义;

              a.2 pathstr=user["+$index()+"]"该处中的user为主体页面数据数组的数组名 ;

              a.3 在完成绑定后,请切换源码,确保view中无"data--url="/v/test.html"类似代码;

             见截图说明: 案例截图说明:

      3)view页面对主体页面的传参处理:

           a,采用自由标注初始化参数

             案例截图说明:

      4)view视口返回值处理:

            a,view视口返回值在返回时,需指点数据位置:pathstr---(该信息有主页面传递而来)

            案例截图说明:

            案例视频:

               案例功能逻辑说明:

                   显示用户列表,主页面只获取用户id,并将id传递给view,由view去获取用户的姓名;循环view以获取用户列表信息;

           视频地址:

    拓展延伸-------- 多层view嵌套循环

         要点总结:

          1,多层view嵌套循环与上述案例中的单层循环的实现原理是相同的;

          要点：第二层的数组要绑在第一层的view里面，加个view，然后绑定数组，和第一层一样的格式就可以

          2,数据的初始化只需要初始化第一层view数据即可，要把添加的二级数组也初始化到主页面的大数组里面;

         要点：添加第二层数组的数据要在第一层的视口里面，根据查询的内容添加第二层的数组的数据，一级view给二级view传值的时候

         和主页面给一级view传值的步骤一样，一级view视口返回数据的时候要把这个数组也返回，然后二级view里面的视口返回二级数组里面的信息点。

          3,第一层view向第二层view的传参同样要指定定位信息:(示例如下)

            {"data--url":"/v/viewtest1.html?id1="+_id()+"&pathstr1="+pathstr()+".gjlb["+$index()+"]"};

          范例： www.test.com/v/viewtest1.html?                                                                         id1=a0c3b4c001cb11e991849bb9dd33c5e1&pathstr1=user[1].gjlb[1]&_ajax=true&_=1545037773229

    参数说明:

         /v/viewtest1.html-------第二层view的url

         pathstr1--------定位信息,其中 pathstr()为当前数据的定位信息;".gjlb["+$index()+"]"-----gjlb为第二层view数据的数组名;

       pathstr()截图说明:

     该步操作对应上述案例中的4,在第二层view所属的数组初始化时，要将上层view的定位变量添加到本数组里，方便第二层数组获取url中的内层定位。（有点类似于二维数组）
