我知道我可以这样过滤:
<input type="search" ng-model="searchTable">
<table>
<thead>
<tr>
<th>First Name</th>
<th>Last Name</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="row in $ctrl.rows | filter: searchTable">
<td>{{ row.firstName }}</td>
<td>{{ row.lastName }}</td>
</tr>
</tbody>
</table>
如果<input type="search" ng-model="searchTable">
,我该如何过滤和<tr ng-repeat="row in $ctrl.rows | filter: searchTable">
位于单独的组件中?
这是一个简单的 fiddle 。
据我了解,我需要添加 $onChanges()
和表达式绑定(bind) bindings: { onChange: '&' }
到searchComponent
,但不完全理解如何实现。
谢谢
最佳答案
Here是工作 fiddle 。您将搜索词存储在父组件中并将其传递给两个子组件。
var app = angular.module('app', []);
app.controller('appController', function() {
this.search = "";
});
app.component('searchComponent', {
template: `
<h4>{{ $ctrl.title }}</h4>
<label>Search table</label>
<input type="search" ng-model="$ctrl.search">
`,
controller: function() {
this.title = 'Search Component';
},
bindings: {
search: "="
}
});
app.component('tableComponent', {
template: `
<h4>{{ $ctrl.title }}</h4>
<!-- <p>This works</p>
<label>Search table</label>
<input type="search" ng-model="searchTable"> -->
<table>
<thead>
<tr>
<th>First Name</th>
<th>Last Name</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="row in $ctrl.rows | filter: $ctrl.search">
<td>{{ row.firstName }}</td>
<td>{{ row.lastName }}</td>
</tr>
</tbody>
</table>
`,
controller: function() {
this.title = 'Table Component';
this.rows = [
{firstName: 'Zulu', lastName: 'Apple'},
{firstName: 'Alice', lastName: 'xRay'},
{firstName: 'Fred', lastName: 'Rogers'}
];
},
bindings: {
search: "<"
}
});
body {
font-family: 'Arial', sans-serif;
}
table {
border-collapse: collapse;
}
td, th {
border: 1px solid grey;
padding: 5px;
}
label {
display: block;
}
input {
margin-bottom: 10px;
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.7.0/angular.min.js"></script>
