const restaurants = keyArray;
const results = queryString ?
restaurants.filter(this.createFilter(queryString)) : restaurants;
// callback
cb(results);
},
createFilter(queryString) {
return restaurant =>
(restaurant.value.toLowerCase().indexOf(queryString.toLowerCase()) === 0);
}, if querystring exists, results is the restaurants after Filter, otherwise it is the value of restaruants , and then put results into the callback cb to execute
this is a Miki expression
the above writing is equivalent to:
let results = null;
if(queryString ){
results = restaurants.filter(this.createFilter(queryString));
}else{
results = restaurants;
}
cb(results);because some of the fields are dynamic, I wrote a v-for to generate them circularly, but the result is that the aggregate functional parameters pass data that only writes dead columns and dynamically generates data that does not exist . <el-table-col...
<el-dialog title="" :visible.sync="dialogShow" width="20%" > <el-form label-position="right" label-width="100px" :model="deptInfo" :rules="rules" ref="deptInfo"...
gets a three-tier nested data in the format of [ { name: 1, id: 1, children: [ { name: 2, id: 2, children: [ { name: 3, id: 3 } ] } ] }, { ...
