page.insert_html 未正确渲染部分
以下内容位于文本字段中。
= f.text_field :title, :size => 50, :onchange => remote_function(:update => :suggestions, :url => {:action => :display_question_search_results})
以下内容位于 display_questions_search_results.rjs 中。
page.insert_html :bottom, 'suggestions', :partial => 'suggestions'
每当用户键入时，我想在数据库中搜索与文本字段中的关键字匹配的任何元组。然后，显示这些结果。但是，目前，_suggestions.haml 仅包含“建议！！”一词。
但是，看到的不是“建议！！”在 suggestions div 标签中，我得到：
try { Element.insert("suggestions", { bottom: "suggestions!!" }); } catch (e) { alert('RJS error:\n\n' + e.toString()); alert('Element.insert(\"suggestions\", { bottom: \"suggestions!!\" });'); throw e }
我一直在试图找出这样做的原因，但我发现之前提出的问题似乎比我正在做的更复杂......
The following is in the text_field.
= f.text_field :title, :size => 50, :onchange => remote_function(:update => :suggestions, :url => {:action => :display_question_search_results})
The following is in display_questions_search_results.rjs.
page.insert_html :bottom, 'suggestions', :partial => 'suggestions'
Whenever the user types, I'd like to search the database for any tuples that match the keywords in the text field. Then, display those results. But, at the moment, _suggestions.haml only contains the word "suggestions!!".
But, instead of seeing "suggestions!!" in the suggestions div tag, I get:
try { Element.insert("suggestions", { bottom: "suggestions!!" }); } catch (e) { alert('RJS error:\n\n' + e.toString()); alert('Element.insert(\"suggestions\", { bottom: \"suggestions!!\" });'); throw e }
I've been trying to find out why this is being done, but the previously asked questions I found seem more complicated than what I'm doing...

如果您指定要更新的元素，则假定您的操作将返回 html（不是 rjs/javascript），这将替换指定元素的内容。
因此，如果您需要替换
:suggestions的内容，只需在控制器中渲染部分即可：但是如果您需要向此元素添加内容而不是替换，请删除
:update => :suggestions来自您的视图代码：并将控制器代码保留为原样：
If you specify element to update, it is assumed that your action will return html (not rjs/javascript), that will replace contents of specified element.
So, if you need to replace contents of
:suggestions, just render partial in your controller:But if you need to add contents to this element, not to replace, remove
:update => :suggestionsfrom your view code:And leave controller code as is:
