this is the code for the loop

 <div v-for="pageData in pageData" >
                <transition 
                    v-on:before-enter="beforeEnter"
                    v-on:enter="enter"
                    v-on:leave="leave"
                    v-bind:css="false"
                >   
                    <page :key="pageData._Id" v-if="flag" :pageData="pageData" :subPageData="subPageData" :resObject="resObject"></page>
                </transition>   
            </div>

Sub-component code

 <div class="page" v-bind:style="{
                            width:"100%",
                            height:"0px",
                            paddingBottom:data._PercentHeight,
                            backgroundColor:data._BackgroundColor,
                            backgroundImage:"url(/static/images/"+data._BackgroundImg+")",
                        } "
                        v-if="data._Id == showPageId" key="data._Id">
                            <div>xxxxxxxxxxx</div>
                        </div>

this is the code for the animation

methods:{
    // 
         beforeEnter: function (el) {
              //
               el.style.opacity = 0
        },
        enter: function (el, done) {
            //"..."
          Velocity(el, { opacity: 1})
          Velocity(el, { complete: done })
        },
        leave: function (el, done) {
            //
          Velocity(el, {
            opacity: 0
          }, { complete: done })
        },
    }

what result do you expect? What is the error message actually seen?

how can I give different animation methods to the ergodic div by judging the value of pageData.type

use animate.js, and then distinguish the data, and change different entry methods by adding different class names

<transition enter-active-class="slideInLeft" leave-active-class="slideOutUp">
    <div v-if = "isShow" class="box animated"></div>
</transition>

introduce the js and css, of animate, and then add a filter to the data by adding the class name to the data. if you want to animate the time, you can change it in css.
