Here is the example you can use to iterate Map.
1. Create Apex class StudentController.cls:
public class StudentController {
@AuraEnabled(cacheble=true)
public static Map<String, String> fetchStudentData(){
Map<String, String> mapStudentData = new Map<String, String>();
mapStudentData.put('Om','BCS');
mapStudentData.put('Sai','BTech');
mapStudentData.put('Ram','BE Computer Science');
mapStudentData.put('Radhe','BE Civil');
return mapStudentData;
}
}
2. Create LWC LWCStudentMap.html:
<template>
<lightning-card icon-name="standard:account" variant="base" title="LWC Map Demo">
<table class="slds-table slds-table_cell-buffer slds-table_bordered">
<thead>
<tr class="slds-line-height_reset">
<th scope="col"> Name </th>
<th scope="col"> Faculty </th>
</tr>
</thead>
<tbody>
<template for:each={mapStudentData} for:item="objMap">
<tr class="slds-hint-parent" key={objMap.key}>
<th scope="col">
<div title={objMap.key}> {objMap.key} </div>
</th>
<th scope="col">
<div title={objMap.value}> {objMap.value} </div>
</th>
</tr>
</template>
</tbody>
</table>>
</lightning-card>
</template>
3. Create LWC LWCStudentMap.js:
import { LightningElement, track, wire } from 'lwc';
import fetchStudentData from '@salesforce/apex/StudentController.fetchStudentData'
export default class LWCStudentMap extends LightningElement {
@track mapStudentData = [];
@track error;
@wire(fetchStudentData)
wiredData({ error, data }) {
if (data) {
console.log('Data', data);
var consts = data;
for(var key in consts)
this.mapStudentData.push({value:consts[key], key:key});
} else if (error) {
console.error('Error:', error);
this.error = error;
}
}
}
