Question

以下是我当前的代码：http://jsfiddle.net/9B84H/1/

var current_place;

function autosuggest() {
    var input = document.getElementById('location');
    var options = { types: [], };
    var autocomplete = new google.maps.places.Autocomplete(input, options);

    google.maps.event.addListener(autocomplete, 'place_changed', function() {
        var place = autocomplete.getPlace();
        if (!place.geometry) {
            current_place = null;
            alert('Cannot find place');
            return;
        } else {
            current_place = place;
            alert('Place is at:' + place.geometry.location);
        }
    });

}

单击autosuggest中的选项时，它可以正常工作。但是，如果您只是输入内容并单击搜索，我需要它来运行与从autosuggest中选择选项时相同的地理编码操作。我该怎么做？

由于current_place是GLOBAL，因此可以在函数外部访问

var current_place;

function autosuggest() {
var input = document.getElementById('location');
var options = {
    types: [],
};
var autocomplete = new google.maps.places.Autocomplete(input, options);

google.maps.event.addListener(autocomplete, 'place_changed', function() {
    var place = autocomplete.getPlace();
    if (!place.geometry) {
        current_place = null;
        alert('Cannot find place');
        return;
    } else {
        current_place = place;
        alert('Place is at:' + place.geometry.location);
        doIt();
    }
});

}
function doIt(){
    alert(current_place.geometry.location);
}
