作为Uncaught ReferenceError分配的无效左侧

Question

使用代码段

时，我从下面的代码中获得了引用错误

它在行号11（变更请求）附近说错误

我很想知道如何让它无错误

function getAddress() {
    var siteUrl = $('#siteUrl').val();

    var geocoder = new google.maps.Geocoder();
    var county_text = $('#adv_county').val();
    var postal_code = $('#adv_postcode').val();
    county_text = county_text ? county_text + ',' + postal_code : postal_code;
    if (!county_text) {
        return false;
    }
    $('.addressfields').val('');
    var request = {
        address: county_text,
        componentRestrictions: {
            country: 'UK'
        }
    };

}
$('#adv_county,#adv_postcode').change(function () {
    getAddress();
});
function initialize() {
    var adv_county_input = document.getElementById('adv_county');
    var postcode_input = document.getElementById('adv_postcode');
    var options = {
        //types: ['address'],
        componentRestrictions: {
            country: 'uk'
        }
    };
    var autocomplete_county = new google.maps.places.Autocomplete(adv_county_input, options);
    var autocomplete_postcode = new google.maps.places.Autocomplete(postcode_input, options);
}
