html - 如何在 Angularjs 中对 [Array] 值元素进行排序？

Question

我在我的应用程序中使用 MEAN 堆栈，并将 AngularJS 作为我的前端。如何过滤计数和质量字段，My Plunker 例如:- 在支数下拉列表中是yarn count , carn count ,burn count..如果我选择特定的yarn count交易只需要显示....请看我的plunker并帮助我们。 My Plunker

我应该如何自定义我的 JSON 以使用数组中的数组(或)我应该如何在 ng-repeat 中制作 ng-repeat 以实现上述给定场景.

我的 HTML :-

<div class="col-md-6 form-group form-group-default"> 
   <label>Count</label> 
     <select data-ng-model="searchtable.count" id="count" ng-options="item.colorshades[0].count for item in sryarnorders" class="form-control">
         <option value="">All</option>
         </select>
    </div>

和

<div class="col-md-6 form-group form-group-default">
  <label>Quality</label>
     <select data-ng-model="searchtable.quality" id="quality" ng-options="item.colorshades[0].quality for item in sryarnorders" class="form-control"  >
        <option value="">All</option>
      </select>
    </div>

我的数据-ng-模型:-

 data-ng-model="searchtable.count"

和

 data-ng-model="searchtable.quality"

我的过滤器代码:-

filter:searchtable.count.colorshades[0].count

filter:searchtable.quality.colorshades[0].quality

我的数据:-

    $scope.sryarnorders = [
   {
"_id": "579ef3adba3bac040b583b4f",
"user": {
"_id": "57400c32bd07906c1308e2cf",
"displayName": "mani selvam"
},
"__v": 1,
"colorshades": [
{
"_id": "579ef3feba3bac040b583b51",
"quality": "Home Textiles",
"count": "carn count"
},

{
"_id": "579ef3feba3bac040b583b50",
"quality": "Hall Textiles",
"count": "yarn count"
}

}

我创建了 Plunker 以供引用:- My Plunker

Answer 1

选择模型总是返回数组中的完整对象，而不是您设置的值。例如，当您在 plunker 中选择“yarn count”时，searchtable.count 等于

{"_id":"573d7fa0760ba711126d7de5","user":{"_id":"5721a378d33c0d6b0bb30416","displayName":"ms ms"},"__v":1,"colorshades":[{"_id":"573d7fc3760ba711126d7de6","quality":"Home Textiles","count":"yarn count"},{"_id":"579ef3feba3bac040b583b50","color":"56a5b6831746bc1c0b391c7c","quality":"Hall Textiles","count":"carn count"}],"created":"2016-05-19T08:56:00.997Z","actual_delivery_date":"2016-05-19","ex_india_date":"2016-05-19","ex_factory_date":"2016-05-19","po_delivery_date":"2016-05-19","supplier_name":"Fsa","buyer_name":"e21"}

鉴于此，有两种解决方案:

1。相应地过滤

这样过滤:

| filter:searchtable.count.colorshades[0].count | filter:searchtable.quality.colorshades[0].quality

看起来不干净。

2。更改选项

您还可以像这样更改 ng-options:

item.colorshades[0].count as item.colorshades[0].count for item in sryarnorders 

这将使 ng-model 仅返回 item.colorshades[0].count。您仍然需要调整过滤器:

| filter:searchtable.count | filter:searchtable.quality

也许可以使它更清洁，我将不得不研究一下。
