我把它放在ng-repeat中。我waana制作一个过滤器，根据评级（1,2,3,4,5）和价格（0-9; 10 -99,100-999）过滤这些项目。我不知道如何继续进行。任何帮助？

Answer 1

首先，JSON中存在价格代表方式的问题。例如，

"price" :6 $;

无效，应列为

"price" :6 ,

有几种价格会发生这种情况。接下来，您可以使用以下

HTML

<div ng-app="myApp" ng-controller='MainCtrl'>
    Rating : <select ng-model='filterParams.rating' ng-options='i for i in ratingParams'><option value=''></option></select>
     &nbsp;&nbsp;
    Price : <select ng-model='filterParams.price' ng-options="p.range for p in priceParams"><option value=''></option></select>
    <hr/>
    <table class="table table-condensed table-striped" >
        <thead>
            <tr>
            <th>Id</th>
            <th>Type</th>
            <th>Name</th>
            <th>Rating</th>
            <th>Price</th>
            </tr>
        </thead>
        <tbody>
        <tr ng-repeat="j in json | customFilter:filterParams">
            <td>{{j.itemId}}</td>
            <td>{{j.businessType}}</td>
            <td>{{j.name}}</td>
            <td>{{j.rating}}</td>
            <td>{{j.price}}</td>
        </tr>
        </tbody>
    </table>
</div>

以下Javascript：

var app = angular.module("myApp",[]);

app.filter("customFilter", function(){
    return function(items, filterParams){        
        var filteredItems = [];

        if (filterParams) {

            angular.forEach(items, function(value){
                var matchRating = true, matchPrice = true;

                // Ratings filter
                if (filterParams.rating){ matchRating = value.rating >= filterParams.rating;}

                // Price filter
                if (filterParams.price){ matchPrice = value.price >= filterParams.price.lower &&  value.price <= filterParams.price.upper;}

                // If items pass both filter, include them
                if (matchRating && matchPrice) {filteredItems.push(value);}
            })
        } 
        else {

            // If no filters specified
            filteredItems = items;   
        }
        return filteredItems;
    }
})

app.controller("MainCtrl", function($scope){
    $scope.priceParams = [
        {range : '0-9', lower: 0, upper:9},
        {range : '10-99', lower: 10, upper:999},
        {range : '100-999', lower: 100, upper:999}
     ];
    $scope.ratingParams = [1,2,3,4,5];

    $scope.json = [
