Question

我想过滤所有具有 last_login = null 的array_values。如何在VueJS中将数组中的值循环并存储到变量以及上述 last_login = null 数据中？

要过滤的数组值存储在此处： console.log（'this is list'，this.list）

    methods: {
        checkboxNullLogin(){
            try {
                this.searchTrigger = true
                    var output = [];
                    for (var i=0; i < this.newval.length ; ++i){
                    output.push(this.newval[i]);
                    return output;

                    console.log('TEST Null logins',this.output);

            }
    },
    computed: {
        filteredList(){
            try {
                    this.searchTrigger = true
                    this.analyzeValue = []
                    this.analyzeValue = this.newval
                    this.searchInfo()
                    this.loadList(this.analyzeValue)
                    return this.analyzeValue;
                    }else{
                        this.filter = false
                        this.getAllItems()
                        this.searchTrigger = false
                        return null;
                    }
                }
            }

Pageview.Vue

<!--addedtest-->
  <div class="col-md-4 pdashForm1">
       <div class="cbox" v-for="nologin in filterLogin" v-bind:key="nologin">
            <label>NO LOGINS<br>
                <input type="checkbox" v-model="search.nullLogin" v-bind:value="nologin" v-onclick>
                <span class="checkmark"></span>
            </label>
         </div> 
    </div>

数据库表：

让nullValues = yourArray.filter（eachArrayItem => eachArrayItem === null）

VueJS中的数组循环所有空值函数
