Question

come scrivere un javascript, mantenere ons-scroller in fondo?

        <span ng-if="uid == msg.uid " >{{msg.msg}}</span> 
        <span ng-if="uid == msg.uid " style="color:#336699;">：{{msg.nickname}}</span> 
        <span ng-if="uid != msg.uid " style="color:#336699">{{msg.nickname}}：</span> 
        <span ng-if="uid != msg.uid " >{{msg.msg}}</span>

     <ons-bottom-toolbar> 
     <input type="text" class="text-input ng-pristine ng-valid ng-touched" 
    placeholder="文字信息" ng-model="user_msg.message" style="margin:6px;" value="">

Basta creare il ons-scroller e impostare il suo attributo style con position: absolute; bottom: 0px".

HERE è possibile trovare un esempio CodePen funzionante, con il relativo codice.

<ons-navigator> 
 
    <ons-toolbar> 
 
    <div class="center">Scroller</div> 
 
    </ons-toolbar> 
 
    <ons-scroller style="height: 200px; width: 100%; border-bottom: 1px solid #ccc; background-color: white; position: absolute; bottom: 0px"> 
 
    <div style="text-align: center"> 
 
     <h2>I am now scrollable!</h2> 
 
     <h3>Happy scrolling!</h3> 
 
     <h3>Happy scrolling!</h3> 
 
     <h3>Happy scrolling!</h3> 
 
     <h3>Happy scrolling!</h3> 
 
     <h3>Happy scrolling!</h3> 
 
     <h3>Happy scrolling!</h3> 
 
     <h3>Happy scrolling!</h3> 
 
     <h3>Happy scrolling!</h3> 
 
     <h3>Happy scrolling!</h3> 
 
    </div> 
 
    </ons-scroller> 
 
</ons-navigator>
