Salesforce Lightning: Google Places Autocomplete Predictions Search



I have created a lookup component which on entering few characters of a location will display location predictions.

There are 3 methods that has been defined in client-side controller:
  • keyPressController: executed when the user enters a search key. I have taken into consideration that the user need to enter at least 3 characters to fetch the location predictions.
  • selectOption: executed when the user selects a value from the list box
  • clear: executed on click of cross icon to remove the selected value from the lookup

To fetch the results, I am calling Place Autocomplete service, a part of the Google Places API Web Service, using the below Apex method, which returns location predictions in response to this HTTP request. For more details about this web service, please check the link in the references section of this post.
@AuraEnabled
public static string getAddressAutoComplete(String input, String types) {
    String url = 'https://maps.googleapis.com/maps/api/place/autocomplete/json?input='
            + EncodingUtil.urlEncode(input, 'UTF-8')
            + '&types=' + types
            + '&key=' + GoogleMapsController.getGoogleMapsAPIKey();
    return GoogleMapsController.getHttp(url);
}

The response which is in JSON format is parsed in Javascript in the helper method of the component as below:
displayOptionsLocation: function (component, searchKey) {
    var action = component.get("c.getAddressAutoComplete");
    action.setParams({
        "input": searchKey,
        "types": '(regions)'
    });

    action.setCallback(this, function (response) {
        var state = response.getState();
        if (state === "SUCCESS") {
            var options = JSON.parse(response.getReturnValue());
            var predictions = options.predictions;
            var addresses = [];
            if (predictions.length > 0) {
                for (var i = 0; i < predictions.length; i++) {
                    addresses.push(
                        {
                            value: predictions[i].types[0],
                            label: predictions[i].description
                        });
                }
                component.set("v.filteredOptions", addresses);
            }
        }
    });
    $A.enqueueAction(action);
}

The look and feel of this component is controlled by $A.util.addClass and $A.util.removeClass methods.

Salesforce Lightning: Lookup Component


I created a simple lookup component in Lightning. Its fully based on Lightning Design Systems. You can check the Github link in the reference section. During initialization, the component query for the list of strings (using apex code) to be displayed and store in an attribute. So when the user enters a search keyword, the request won't go to Salesforce again and will query the Javascript string array for the filtered results.

How to use?

From your Lightning component, add a lookup component using the following markup:
<c:DemoLookup placeholder="Enter partner Name" actionMethod="c.getAccountOptions"/>

You need to pass a list of strings which will get displayed in the lookup options when the user enters an input. A sample method is as below:
@AuraEnabled
public static List<String> getAccountOptions() {
    List<String> options = new List<String>();
    for (Account a : [
            SELECT Name
            FROM Account
            LIMIT 100
    ]) {
        options.add(a.Name);
    }
    return options;
}
