This time I will show you how to get the value of class in the dom, and what are the precautions for getting the class value in the dom. The following is a practical case, let's take a look.
vue clicks to add a class to the dom and then gets the dom containing the class
<p class="chose-ck" v-for="(item,index2) in colors" :key="index2" ref="chosebox">
<p>{{item.name}}</p>
<dt v-for="(item2,index) in item.childsCurGoods" :key="item2.id" :class="index==iac[index2]?'check':''" :id="item2.id" :data-chosename="item.name" :data-choseidname="item2.name" :data-chose="item.id" :data-id="item2.id" @click="chek(index2,index)" >
{{item2.name}}
</dt>
</p>js
chek(index2, index) {
this.iac[index2] = index
this.iac = this.iac.concat([]);
this.checkchose()
},
checkchose:function(){
var chose=this
var chosedom=chose.$refs.chosebox
console.log(chosedom)
for (var i=0;i<chosedom.length;i++) {
var children=chosedom[i].children
for (var j=0;j<children.length;j++) {
if(children[j].className=="check")
{
console.log(children[j])
}
}
}
}The dom obtained after clicking is printed
if(children[j].className=="check")
Added Determine why the printed DOM is the DOM before clicking
