我无法将变量传递给它.请帮忙.

I can't get the way to pass the variable to it. Please help.

推荐答案

您可以使用此处指定的本地或集合 http://docs.rhomobile.com/rhodes/ui#advanced-usage-of-render

You can use the locals or collections as specified over here http://docs.rhomobile.com/rhodes/ui#advanced-usage-of-render

<%= render :partial =>"mypartial", :locals => { :event => "myevent" } %>

然后局部使用，像

<div class="eventList"><%= event %></div>

第二，如果您为控制器中的实例变量分配了一些值，

Second, if you assign some value to the instance variable in the controller,

@event = "myevent"

然后您可以在部分内部直接访问它，

then you can directly access it inside the partial as below,

<div class="eventList"><%= @event %></div>

这些是您可以用来传递变量的一些方法.

These are some of the ways you can use to pass the variables.
