我有一个实现 Google Places 以自动完成和填充其他文本字段的表单。

    <script type="text/javascript">
    $(document).ready(function(){
        $('.noEnterSubmit').keypress(function(e){
            if ( e.which == 13 ) return false;
        });

        var updateAddress = {

        autocomplete: new google.maps.places.Autocomplete($("#Subscription_address")[0], {types: ['geocode']}),

        event: function(){
            var self = this;    
            google.maps.event.addListener(self.autocomplete, 'place_changed', function() {
                var place = self.autocomplete.getPlace(),
                    address = place.address_components,
                    streetAddress = '',
                    suburb = '',
                    state = '',
                    zip = '',
                    country = '';

                for (var i = 0; i < address.length; i++) {
                    var addressType = address[i].types[0];

                    if (addressType == 'subpremise') {
                        streetAddress += address[i].long_name + '/';
                    }
                    if (addressType == 'street_number') {
                        streetAddress += address[i].long_name + ' ';
                    }
                    if (address[i].types[0] == 'route') {
                        streetAddress += address[i].long_name;
                    }
                    if (addressType == 'locality') {
                        suburb = address[i].long_name;
                    }
                    if (addressType == 'administrative_area_level_1') {
                        state = address[i].long_name;
                    }
                    if (addressType == 'postal_code') {
                        zip = address[i].long_name;
                    }
                    if (addressType == 'country') {
                        country = address[i].long_name;
                    }
                }

                // update the textboxes
                setTimeout(function(){$('#Subscription_address').val(streetAddress).blur(function(e){
                    this.value = this.streetAddress;
                });},50);
                $('#Subscription_city').val(suburb);
                $('#Subscription_state').val(state);
                $('#Subscription_zip').val(zip);
                $('#Subscription_country').val(country);
            });

        }
    };

    updateAddress.event();

    });
    </script>
    </head> 

<input class="noEnterSubmit input-large" name="Subscription[address]" id="Subscription_address" type="text">

我阻止表单在输入键上提交。只有当用户输入按键然后焦点离开文本字段时，#Subscription_address 才会重置，Google Places API 才会显示#Subscription_address 的“未定义”值。

目前，选项卡按键和鼠标选择作为模糊事件按预期工作以填充其他字段并仅保留 #Subscription_address 字段中的 streetAddress。

使用 JQuery，我如何允许用户通过使用 enter 按键选择自动完成结果，然后将注意力集中在文本字段上并保留所选值？

       // update the textboxes
        setTimeout(function(){$('#Subscription_address').val(streetAddress).blur(function(e){
            this.value = streetAddress;
        });},50);

我需要在模糊功能后删除 this.streetAddress 。这在下拉列表的 DOM 中具有不同的上下文。
