AngularJS filter:search 是如何匹配的 ng-repeat filter:search ，filter:{$:search}，只取repeat的item的value 不含label

 

 

1.  filter可以接收参数，参数用 : 进行分割，如下：

{{ expression | filter:argument1:argument2:... }}

2.   filter参数是 对象 ，匹配属性中含有value的

$scope.childrenArray = [
        {name:'kimi',age:3},
        {name:'cindy',age:4},
        {name:'anglar',age:4},
        {name:'shitou',age:6},
        {name:'tiantian',age:5}
    ];

{{ childrenArray | filter : {name : 'i'} }} //参数是对象，匹配name属性中含有i的

示例：angular filter多个字段搜索

<input type="text" ng-model="search ">

<!--<li ng-repeat="user in data.users | filter:{name:search}>  --> 
<!--此时只搜索了name字段-->

<!--搜索name字段、account字段-->
<li ng-repeat="user in data.users | filter:{name:search}:{account:search}> 
<span ng-bind="user.name"></span>
<span ng-bind="user.account"></span>
</li>

3.  没有指定过滤哪个字段的情况下，默认filter会匹配所有字段(name、account)的值，类似 多个字段搜索

ng-repeat="user in data.users | filter:search

4. $ 匹配 对象 所有属性 和  嵌套对象属性

<li ng-repeat="user in data.users | filter:{$:search}> 

5.  bind ng-model to the “value” of selected item  instead of item for ui-select

  <ui-select ng-model="fm.countryCode" id="countryCode">
      <ui-select-match placeholder="Select a country...">{{$select.selected.label}}</ui-select-match>
      <ui-select-choices repeat="item in countries | filter: $select.search" value="{{$select.selected.value}}">
          <div ng-bind-html="item.label | highlight: $select.search"></div>
          <small ng-bind-html="item.value | highlight: $select.search"></small>
      </ui-select-choices>
  </ui-select>   

Currently it's just setting fm.countryCode to the whole country item.

For example if I select Afghanistan, fm.countryCode will be set to {"value":"AF","label":"Afghanistan"}.

What I want is "AF".

so change  the repeat part

<ui-select-choices repeat="item in countries | filter: $select.search" value="{{$select.selected.value}}">

to

<ui-select-choices repeat="item.value as item in countries | filter: $select.search" value="{{$select.selected.value}}">

 示例：

                                            <ui-select ng-model="networkDefaultValue.resourceId" name="networkname" theme="bootstrap" ng-change="setInputDefaultValue(['resource_id'],networkDefaultValue.resourceId,networkDefaultValue.isResourceIdInput)">
                                                <ui-select-match allow-clear="true" placeholder="{{'Select an option'|translate}}">{{$select.selected.name + ' - ' + $select.selected.properties.datacentername}}</ui-select-match>
                                                <ui-select-choices repeat="resource.id as resource in totalNetworks | filter: { $ : $select.search}">
                                                    <div ng-bind-html="resource.name + ' - ' + resource.properties.datacentername | highlight: $select.search"></div>
                                                </ui-select-choices>
                                            </ui-select>
