分页铁阿贾克斯反应

Question

I would like to paginate the iron ajax response but I didn't succeed until now. Any help

 <template is="dom-bind">
      <iron-ajax auto url="test2.json"
       params = '{"A":"5", "B":"888"}'
      handle-as="json" last-response="{{signups}}"></iron-ajax>
      <vaadin-grid items="{{signups}}">
        <table>
          <colgroup>
            <col name="A"/>
            <col name="B"/>
          </colgroup>
        </table>
      </vaadin-grid>
    </template>

尝试使用params = "[[_getParams(A,B,page)]]" ，那么每次您分页++时，都会使用_getParams（）的最新参数进行新的调用
