以下代码是在文本框中输入位置后在地图上查找位置。请在下面的代码中注明我正在使用＆＃39;定位器＆＃39;而不是地理编码器＆＃39;因为我想拥有自定义文本框而不是由＆＃39; esri / dijit / geocoder提供的文本框。而且我想使用定位器获取地理坐标值。
在下面的代码中，我想添加＆＃39; autocomplete＆＃39;文本框中的功能具有与＆＃39; autocomplete＆＃39;相同的功能。地理编码器功能＆＃39;。

如何添加＆＃39;自动完成＆＃39;此代码中的功能？
答案 0 :(得分：1)
使用esri / dijit / geocoder提供的自定义文本框是什么意思？ Geocoder dijit带有默认的ESRI css来设计dijit，但没有什么可以阻止你用自己的风格覆盖它。
例如，您可以在body标签中添加一个类来覆盖claro样式：
<body class="claro custom">
这样esri dijits默认会使用claro，但是如果你定义与esri dijit相同的css选择器并将它们附加到你的自定义类，那么dijit将使用它。这是一个简短的例子，我们覆盖了Geocoder中结果元素的2个属性：
/* Custom styles for the Geocoder dijit */
.custom #myGeocoder .esriGeocoderResults {
overflow: visible;
z-index: 1000 !important;
}

地理编码dijit使用默认定位器或自定义定位器支持自动完成。由于您正在引用默认定位器服务，您只需使用dijit并在选项中传递autoComplete
<script>
var map, geocoder;
require([
"esri/map", "esri/dijit/Geocoder", "dojo/domReady!"
], function(Map, Geocoder) {
map = new Map("map",{
basemap: "gray",
center: [-120.435, 46.159], // lon, lat
zoom: 7
});
geocoder = new Geocoder({
map: map,
autoComplete : true
}, "search");
geocoder.startup();
});
</script>
