Typeahead在列表名称旁边获取多个值

Eze*_*wei 0 angularjs angular-ui angular-ui-bootstrap angular-ui-typeahead

我发现很难想象为typeahead指令获取一组值的方法.

例如,在这个plunker中,http: //plnkr.co/edit/Sj0kOGipJ4gNv3VCnKzJ？p =preview

的index.html

<!doctype html>
<html ng-app="plunker">
  <head>
    <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.2.10/angular.js"></script>

    <script src="example.js"></script>
    <link href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css" rel="stylesheet">

      <span bind-html-unsafe="match.label | typeaheadHighlight:query"></span>
  </a>
</script>
<div class='container-fluid' ng-controller="TypeaheadCtrl">

    <h4>Static arrays</h4>
    <pre>Model: {{selected | json}}</pre>
    <input type="text" ng-model="selected" typeahead="state for state in states | filter:$viewValue | limitTo:8" class="form-control">

    <h4>Asynchronous results</h4>
    <pre>Model: {{asyncSelected | json}}</pre>
    <input type="text" ng-model="asyncSelected" placeholder="Locations loaded via $http" typeahead="address for address in getLocation($viewValue)" typeahead-loading="loadingLocations" class="form-control">
    <i ng-show="loadingLocations" class="glyphicon glyphicon-refresh"></i>

    <h4>Custom templates for results</h4>
    <pre>Model: {{customSelected | json}}</pre>
    <input type="text" ng-model="customSelected" placeholder="Custom template" typeahead="state as state.name for state in statesWithFlags | filter:{name:$viewValue}" typeahead-template-url="customTemplate.html" class="form-control">

当你搜索并选择时,它只取一个值作为条目本身就是一个.但是,如果我想在地址旁边拿一个居民的名字,保留供将来使用甚至是表格,该怎么办？

我尝试通过传递像item.residentName这样的值来做到这一点,它只会显示一个地址列表,其中包含未定义的每个地址(前置条件是正确填充了residentName).或者如果我传递.push(对象),该对象是一个对象而不是一个只有值的var,它会将每个列表项显示为[Object,object].

==进一步澄清 例如在最后一步中getLocation(),我想要传递而不仅仅是item.formatted_address,我想要传递,item.geometry而生成的列表仍将显示formatted_address.

如果有意义,请告诉我.

谢谢

这是一个有效的插件:http://plnkr.co/edit/hCIjHfEYDXhiCL4lOMBb

视图修改如下:

typeahead="address as address.formatted_address for address in getLocation($viewValue)"

因此,"地址"将与模型绑定.它将显示为'formatted_address'

您可以在doc中找到有关所有可能性的更多信息:https: //docs.angularjs.org/api/ng/directive/select查看ng-options语法

控制器修改如下:

angular.forEach(res.data.results, function(item){
addresses.push({
    formatted_address: item.formatted_address,
    geometry: item.geometry
    });
});
