To implement dynamic search functionality in a Lightning Web Component (LWC) in Salesforce, you can follow the steps below:
1. Create the HTML Markup:
Start by creating the HTML markup for your LWC component. Include an input field where users can enter their search criteria, and a list to display the search results dynamically.
<template>
<lightning-input type="text" label="Search" onchange={handleSearch}></lightning-input>
<ul>
<template for:each={searchResults} for:item="result">
<li key={result.Id}>{result.Name}</li>
</template>
</ul>
</template>
2. Define the JavaScript Controller:
Create a JavaScript controller to handle the search functionality and update the search results based on user input.
import { LightningElement, wire } from 'lwc';
import searchRecords from '@salesforce/apex/YourApexClass.searchRecords';
export default class DynamicSearch extends LightningElement {
searchResults = [];
handleSearch(event) {
const searchTerm = event.target.value;
searchRecords({ searchKey: searchTerm })
.then(result => {
this.searchResults = result;
})
.catch(error => {
// Handle any error that occurs during the search
});
}
}
3. Implement the Apex Controller:
In your Apex class, implement the searchRecords method to query the relevant records based on the search criteria and return the results.
public with sharing class YourApexClass {
@AuraEnabled(cacheable=true)
public static List<Account> searchRecords(String searchKey) {
String searchTerm = '%' + searchKey + '%';
return [SELECT Id, Name FROM Account WHERE Name LIKE :searchTerm LIMIT 10];
}
}
```
4. Wire the Apex Method:
Use the wire decorator in your LWC to call the Apex method and retrieve the search results.
import { LightningElement, wire } from 'lwc';
import searchRecords from '@salesforce/apex/YourApexClass.searchRecords';
export default class DynamicSearch extends LightningElement {
searchResults = [];
@wire(searchRecords, { searchKey: '' })
wiredSearchResults({ error, data }) {
if (data) {
this.searchResults = data;
} else if (error) {
// Handle any error that occurs during the initial retrieval
}
}
handleSearch(event) {
const searchTerm = event.target.value;
searchRecords({ searchKey: searchTerm })
.then(result => {
this.searchResults = result;
})
.catch(error => {
// Handle any error that occurs during the search
});
}
}
By following these steps, you can create a dynamic search functionality in your LWC component. As users enter their search criteria, the component will dynamically update the search results based on the entered value.
Please note that the example provided is a basic implementation and may need modification based on your specific requirements.
