Create geocoder:

var localSearch = null;
//查询参数
var options = {
   //智能搜索
   onSearchComplete: function (results) {
    //查询结果状态码
    if (localSearch.getStatus() == BMAP_STATUS_SUCCESS) {
     var s = convertMapSearch(results); //对结果进行处理
     model.locationAddress(s); //将结果数据赋予knockout对象数组（可用其他数组对象代替）
    }
   }
  };
  localSearch = new BMap.LocalSearch("城市", options);

Combine knockout’s textInput binding method and the object’s subscribe attribute to realize the real-time query function for changes in the input box.

//绑定
<input id="txtAddress" type="text" placeholder="请输入用餐地址" data-bind="textInput: addressInput" />
//subscribe属性 在输入变化的时候执行地址查询
sf.addressInput.subscribe(function (val) {
   var addr = $.trim(val);
   if (addr == "") {
    return;
   }
   localSearch.search(addr);
  });
