jQuery and google maps auto complete

I have Google Maps Autocomplete working on severalinput tags like this:

 <input class="controls pac-input" id="pac-input" type="text" onfocus="geolocate()" placeholder="Type custom address" />

To enable Google Maps auto-complete, I have the following code:

//https://developers.google.com/maps/documentation/javascript/examples/places-autocomplete-addressform
$(document).ready(function () {

    autocomplete = new google.maps.places.Autocomplete((document.getElementById('pac-input')), { types: ['geocode'] });

    google.maps.event.addListener(autocomplete, 'place_changed', function () {
        MyFunc();
    });

});

And then, in the MyFunc() function I do what I need:

function MyFunc() {
    var fullAddress = autocomplete.getPlace().formatted_address;
    var input = $(this);
    //stuff that uses input
}

This code however, has two problems:

Thanks in advance!

You don't need jQuery for this. Here is a working example using only javascript:

HTML:

<input class="autocomplete" id="ac1" placeholder="Enter your address" type="text"></input>
<input class="autocomplete" id="ac2" placeholder="Enter your address" type="text"></input>
<input class="autocomplete" id="ac3" placeholder="Enter your address" type="text"></input>

JavaScript:

var acInputs = document.getElementsByClassName("autocomplete");

for (var i = 0; i < acInputs.length; i++) {

    var autocomplete = new google.maps.places.Autocomplete(acInputs[i]);
    autocomplete.inputId = acInputs[i].id;

    google.maps.event.addListener(autocomplete, 'place_changed', function () {
        console.log('You used input with id ' + this.inputId);
    });
}

JSFiddle demo

If you want to do it with jQuery then you can try this way:

$('.autocomplete').each(function() {
    
    var autocomplete = new google.maps.places.Autocomplete($(this)[0]);
    autocomplete.inputId = $(this).attr('id');

    google.maps.event.addListener(autocomplete, 'place_changed', function () {
        console.log('You used input with id ' + this.inputId);
    });
});

JSFiddle demo

Hope this helps.

In order to find out which input element is being called, you could pass the event to MyFunc(). Using $(this) isn't going to check outside of that function to see what called it.

Update the addListener to the following.

google.maps.event.addListener(autocomplete, 'place_changed', function (e) {
    MyFunc(e);
});`

And update MyFunc() to

function MyFunc(e) {
    var fullAddress = autocomplete.getPlace().formatted_address;
    var input = e;
    //stuff that uses input
}

You can then use input as the variable that holds the information about the element being updated. If you do console.log(input); below the var input = e; you will see a list of items you can use to get the data.

You may be most interested in setting var input = e; to var input = e.target; instead. This will allow you to get the information about the input easily.

Example: input.value would return the value of the input in question.
