Question

我正在为搜索表单提取主干集合。我想我想在每次搜索后重置集合，因为目前搜索结果只是将新结果附加到之前的结果中。

目前@ collection.reset（）完全没有。

class ****.Views.DesignerSearchView extends Marionette.CompositeView

  className: 'tab_pane'

  id: 'search_items'

  template: JST['designer/DesignerSearchTemplate']


  itemView: (obj) ->
    new Mywebroom.Views.DesignerSearchItemsLayout(obj)

  itemViewContainer: "div"

  events: {
    'keyup #designer_search': 'search'
    'click .fa-times ': 'clearSearch'
  }

  initialize:->

    @collection = new Mywebroom.Collections.SearchItems()


  search: ->

    searchTerm = $('#designer_search').val()

    @collection.reset()
    @collection.fetch({
      data: $.param({ search : searchTerm })

      async: false
      success: (collection, response, options) ->
        console.log("designs fetch success", response)

      error: (collection, response, options) ->
        console.error("designs fetch fail", response.responseText)
    })

修改

Per CharlieBrowns的建议：

search: ->

    searchTerm = $('#designer_search').val()

    @collection.fetch({
      data: $.param({ search : searchTerm })

      async: false
      reset: true
      success: (collection, response, options) ->
        console.log("designs fetch success", response)

      error: (collection, response, options) ->
        console.error("designs fetch fail", response.responseText)
    })

和

search: ->

    searchTerm = $('#designer_search').val()

    @collection.reset([])
    @collection.fetch({
      data: $.param({ search : searchTerm })

      async: false
      success: (collection, response, options) ->
        console.log("designs fetch success", response)

      error: (collection, response, options) ->
        console.error("designs fetch fail", response.responseText)
    })

但仍然没有运气

Answer 1

您有两种选择：

使用collection.reset（[]）重置集合并添加0个新模型。
使用collection.fetch（{reset：true}）重置每次提取的集合。

重置/清除Backbone集合
