请大神指点谢谢，想实现点击加载更多列表内容出错

WAService.js:3 thirdScriptError

this.loadDate is not a function;at “pages/test/test” page loadMore function

TypeError: this.loadDate is not a function

<ignore_js_op style=""> </ignore_js_op>

点击

<view bindtap=“loadMore” data-lastid="{{lastid}}">加载更多</view>

获取传值的loadDate总是错

loadMore: function (event) {

    var that = this

    var id = event.currentTarget.dataset.lastid

    this.loadDate(id);

  }
