这是我的第一个VueJS项目（从jQuery转移），我正在尝试使用多个复选框过滤网格。正如你在JavaScript中看到的，我有一个filterJobs函数，它使用从whats检查的值设置过滤数组（v-model =＆＃34; checkedLocations＆＃34;）。 array.includes似乎过滤单个值，我想过滤多个值。我不想弹出或切片阵列，因为如果他们取消选中某个位置，他们就会离开并赢得重新绑定
let careers = careers || {};
careers.taleo = (function($){
let app;
let init = function() {
app = new Vue({

在列出作业的位置使用v-if：
<div class="job" v-if=filterJobs(job) v-for="job in jobs">
并使用方法filterJobs：
filterJobs: function(data) {
if (this.checkedLocations.length == 0) return true;
return this.checkedLocations.includes(data.location);
}
