this.$store.state数据改变后, computed未生效, 困惑了很久, 不知道哪里出了问题...感谢您的阅读和解答.
1、computed
computed: {
msgInfo() {
for (var i in this.$store.state.msgList.groupMsg) {
if (this.$store.state.msgList.groupMsg[i].tid == this.$route.query.tid) {
return this.$store.state.msgList.groupMsg[i]
}
}
}
},
2、模板调用
<div class="row clearfix" v-for="item in msgInfo.msg" :key="item.mid">
<img :src="item.headerUrl" class="header">
<div class="content">
<div class="content-header" style="height:10px;">
<p style="float:left;">{{item.fromname}}</p>
<p style="float:right;">{{item.createtime}}</p>
</div>
<div class="clear"></div>
<p class="text" v-more>{{item.content}}</p>
<div class="content-footer">
<p style="float:right;">--来自: {{item.groupname}}</p>
</div>
<div class="clear"></div>
</div>
</div>
3、数据变更
var has = this.$store.state.msgList.groupMsg.some((item, index, array) => {
if(item.tid == data.tid){
this.$store.state.msgList.groupMsg[index].nexttime = data.create_time;
this.$store.state.msgList.groupMsg[index].msg.push({
group : data.group,
groupname : data.groupname,
robotid : data.rid,
mid : data.mid,
from : data.from,
fromname : data.fromname,
content : data.content,
headerUrl : "http://q.qlogo.cn/headimg_dl?bs=qq&dst_uin=" + data.from + "&fid=blog&spec=100",
createtime : data.create_time
});
return true;
}
});
