防止重复值出现在Angular
我有一个表单，根据用户选择的下拉菜单查找医生。
以下表格：
当用户在下拉列表中选择城市并点击搜索时，它会检索城市内的紧急护理。但是，它重复相同的位置。下面的代码是：
<div class="panel panel-default">
<div class="panel-body">
<form name="UrgentCareSearch" ng-submit="SearchUrgentCare(searchParam);" novalidate role="form">
<div style="margin-top:-10px; margin-bottom:10px; text-align:center; font-size:8pt! important"><strong>Search by<br> URGENT CARE NAME AND/OR CITY </strong></div>
<div class="form-group"><input class="form-control" id="urgentcare" ng-model="searchParam.UrgentCareName" placeholder="Urgent Care Name" type="text" /></div>
<!---<div class="form-group"><input class="form-control" id="urgentcare" name="Urgent Care Name" onblur="if(this.value === '') this.value = 'Urgent Care Name';" onfocus="if(this.value === 'Urgent Care Name') this.value = '';" type="text" value="Urgent Care Name" /></div>--->
<div class="form-group">
<!---<select class="form-control margin-bottom1" id="city" ng-model="searchParam.City" ng-options="City.value for City in Cities">
<option disabled="disabled" selected="selected" value="">City</option> </select>--->
<SELECT name="proCity" class="form-control margin-bottom1" placeholder="City" ng-model="searchParam.City">
<option disabled="disabled" selected="selected" value="">City</option>
<option value=""></option>
<cfoutput query="UCarecityFind">
<option value=#officecity#>#officecity#</option>
</cfoutput>
</select>
</div>
<hr / style="border-width: thick; background-color: black" >
<div style="margin-top:-10px; margin-bottom:10px; text-align:center; font-size:8pt! important"><strong>OR<br> Search by ZIP CODE RADIUS </strong></div>
<div class="row">
<div class="col-xs-7 no-right-padding">
<div class="form-group">
<div class="input-group"><select class="form-control" name="distance" ng-model="searchParam.Distance" ng-options="mile.value for mile in miles"><option selected="selected" value=" "></option><option >5</option><option>10</option><option>15</option><option>20</option></select>
<div class="input-group-addon">miles</div>
</div>
</div>
</div>
<div class="col-xs-5 no-left-padding widthZip">
<div class="form-group"><input allow-pattern="[\d\W]" class="form-control" id="zip" maxlength="5" ng-model="searchParam.Zip" placeholder="Zip code" type="text" /></div>
</div>
</div>
<div class="form-group"><input class="btn btn-warning btn-block" ng-click="gotoElement('SearchResultsAnchor');" type="submit" value="Search" /></div>
</form>
</div>
以下代码显示基于用户选择/输入的结果：
<div>
<nav class="hidden-xs visible-md visible-lg" ng-show="ShowResults"><uib-pagination boundary-links="true" max-size="maxPageNumbersToShow" ng-model="currentPage" total-items="resultsCount"> </uib-pagination></nav>
<nav class="visible-xs hidden-md hidden-lg" ng-show="ShowResults"><uib-pager ng-model="currentPage" total-items="resultsCount"> </uib-pager></nav>
<div class="container" id="searchResults" ng-repeat="e in urgentCareCenters" ng-show="ShowResults">
<div class="row">
<hr />
<div class="col-md-12 no-margin">
<h4>{{e.OfficeName}}</h4>
</div>
</div>
<div class="row">
<div class="col-md-4"><strong>Address:</strong> <i class="glyphicon glyphicon-map-marker"></i> <a href="https://maps.google.com?saddr=Current+Location&daddr={{e.GoogleParams}}" target="_blank"> {{e.OfficeAddress}}</a><br />
<a class="shiftAddUrgent padding" href="https://maps.google.com?saddr=Current+Location&daddr={{e.GoogleParams}}" target="_blank">{{e.OfficeCity}}, {{e.OfficeState}} {{e.OfficeZipCode}}</a></div>
<div class="col-md-4 no-margin padding"><strong>Phone: </strong><i class="glyphicon glyphicon-earphone"></i> {{e.OfficePhone | PhoneNumber}}<br />
<strong>Office hours: </strong> <i class="glyphicon glyphicon-time"></i> {{e.OfficeHours}}</div>
</div>
</div>
<nav class="visible-xs hidden-md hidden-lg" ng-show="ShowResults">
<hr /><uib-pager ng-model="currentPage" total-items="resultsCount"> </uib-pager></nav>
</div>
我想在显示结果之前检查值是否重复。如果他们是重复的信息，我想阻止它。我怎么做到这一点？
以下代码是我用来检索数据的代码。我仍在学习角度，所以如果代码看起来很糟糕或者这是一个简单的解决方案，我会道歉。

这将根据某个属性删除数组中的对象。所以......
const removeDuplicates= (myArr, prop) => {
return myArr.filter((obj, pos, arr) => {
return arr.map(mapObj => mapObj[prop]).indexOf(obj[prop]) === pos;
});
}
$http.get("/includes/remote/ReturnUrgentCareList.cfm" + queryString)
.success(function(response){
var dupsRemoved = removeDuplicates(response.UrgentCareCenters,'OfficeName');
$scope.urgentCareCenters = dupsRemoved
// ... rest of code
}
此外，您还需要在HTML中的ng-repeat中添加track by。您可以使用$ index或id。
<div class="container" id="searchResults" ng-repeat="e in urgentCareCenters track by $index" ng-show="ShowResults">
<div class="row">
<hr />
<div class="col-md-12 no-margin">
<h4>{{e.OfficeName}}</h4>
</div>
</div>
<div class="row">
<div class="col-md-4"><strong>Address:</strong> <i class="glyphicon glyphicon-map-marker"></i> <a href="https://maps.google.com?saddr=Current+Location&daddr={{e.GoogleParams}}" target="_blank"> {{e.OfficeAddress}}</a><br />
<a class="shiftAddUrgent padding" href="https://maps.google.com?saddr=Current+Location&daddr={{e.GoogleParams}}" target="_blank">{{e.OfficeCity}}, {{e.OfficeState}} {{e.OfficeZipCode}}</a></div>
<div class="col-md-4 no-margin padding"><strong>Phone: </strong><i class="glyphicon glyphicon-earphone"></i> {{e.OfficePhone | PhoneNumber}}<br />
<strong>Office hours: </strong> <i class="glyphicon glyphicon-time"></i> {{e.OfficeHours}}</div>
</div>
</div>
