Question

我正在尝试在输入上放置一个清除按钮以删除Google Map V3中的文本。

CSS：

#searchclear {
    //Doesn't matter what I put
}

一般Javascript：

 var input = /** @type {HTMLInputElement} */(
      document.getElementById('pac-input'));
  map.controls[google.maps.ControlPosition.TOP_LEFT].push(input);

    var searchclear = /** @type {HTMLInputElement} */(
      document.getElementById('searchclear'));

  map.controls[google.maps.ControlPosition.TOP_LEFT].push(searchclear);

HTML：

<input id="pac-input" class="controls" type="text" placeholder="Search food, sites, places">                    
<span id="searchclear" class="glyphicon glyphicon-remove-circle" onclick="clearAllSearch()"></span>

我知道它与map.controls上的TOP_LEFT有关，但是如何更改它以便我可以在删除按钮上实际使用display：inline-block？如果我删除下面的行，则删除按钮将被放置在地图之外。 map.controls[google.maps.ControlPosition.TOP_LEFT].push(searchclear);

我可以使用绝对定位，但当浏览器窗口缩小或展开时，删除按钮将缩放和中断。

有什么建议吗？我试图将x放在输入中，在最右边。

您可以考虑以下方法。

将图标和输入元素放在容器中：

window.alert

您可以使用以下CSS左右对齐字形：

<div id="search-container" class="inner-addon right-addon">
        <input id="pac-input" class="controls" type="text" placeholder="Enter a location">
        <span id="searchclear" class="glyphicon glyphicon-remove-circle" onclick="clearAllSearch()"></span>
</div>

最初此css已发布在this answer

最后将控件放在地图上：

/* enable absolute positioning */
.inner-addon { 
    position: relative; 
}

/* style icon */
.inner-addon .glyphicon {
  position: absolute;
  padding: 10px;
  pointer-events: none;
}

/* align icon */
.left-addon .glyphicon  { left:  0px;}
.right-addon .glyphicon { right: 0px;}

/* add padding  */
.left-addon input  { padding-left:  30px; }
.right-addon input { padding-right: 30px; }

    autocomplete.addListener('place_changed', function () {

        marker.setVisible(false);
        var place = autocomplete.getPlace();
        if (!place.geometry) {
            window.alert("Autocomplete's returned place contains no geometry");
            return;
        }

        // If the place has a geometry, then present it on a map.
        if (place.geometry.viewport) {

        } else {
            map.setCenter(place.geometry.location);

            origin: new google.maps.Point(0, 0),
            anchor: new google.maps.Point(17, 34),
            scaledSize: new google.maps.Size(35, 35)
        }));
        marker.setPosition(place.geometry.location);
        marker.setVisible(true);

        var address = '';
        if (place.address_components) {
            address = [
              (place.address_components[0] && place.address_components[0].short_name || ''),
              (place.address_components[1] && place.address_components[1].short_name || ''),
              (place.address_components[2] && place.address_components[2].short_name || '')
            ].join(' ');
        }

        infowindow.setContent('<div><strong>' + place.name + '</strong><br>' + address);
        infowindow.open(map, marker);
    });
}

function clearAllSearch() {
    
}
