我的所有指令都使用相同的范围,我希望我的指令可以自己操作.
指示：
app.directive('headerSort',function () {
return {
restrict: 'A',controller: function ($scope,$element,$attrs) {
$scope.caption = $attrs.caption;
$scope.doSort = function () {
$scope.orderField = $attrs.headerSort;
$scope.reverse = !$scope.reverse;
};
},template: '<div data-ng-click="doSort();">' +
'{{caption}}' +
'<i class="icon-sort"></i>' +
'</div>'
};
});
HTML：
<th data-header-Sort="FullName" data-caption="Full name"></th> <th data-header-Sort="FirsName" data-caption="First name"></th> <th data-header-Sort="Age" data-caption="Age"></th>
结果是所有列都具有值’Age’并按Age排序.我当然希望每列都对它自己的列进行排序.我怎样才能做到这一点？
更新：
忘了在ng-repeat中使用orderField和reverse排序依据：
<tbody id="customerRows" data-ng-repeat="customer in customers | orderBy:orderField:reverse">
指令的每个实例都需要有自己的标题,排序类型和反向属性.因此该指令将需要其自己的(子)范围 – 隔离范围(范围：{})或新范围(范围：true).由于该指令不是独立/自包含组件,因此我不会使用隔离范围(另请参阅
When writing a directive in AngularJS,how do I decide if I need no new scope,a new child scope,or a new isolated scope?).
使用为指令选择的作用域类型,可以通过函数参数将排序类型和反向值传递给父类,也可以直接在父作用域上设置它们.我建议函数参数：
app.directive('headerSort',function () {
return {
scope: true,// creates a new child scope
link: function (scope,element,attrs) {
scope.caption = attrs.caption;
scope.sortType = attrs.headerSort;
scope.reverse = false;
},template: '<div data-ng-click="reverse=!reverse; doSort(sortType,reverse);">' +
'{{caption}}</div>'
};
});
function MyCtrl($scope) {
$scope.orderField = "FirstName";
$scope.reverse = false;
$scope.customers = [ {FirstName: 'Martijn',Age: 22},{FirstName: 'Mark',Age: 44}];
$scope.doSort = function (sortType,reverse) {
console.log('sorting',sortType,reverse);
$scope.orderField = sortType;
$scope.reverse = reverse;
};
}
<table>
<th data-header-sort="FirstName" data-caption="First name"></th>
<th data-header-sort="Age" data-caption="Age"></th>
<tbody id="customerRows" data-ng-repeat="customer in customers | orderBy:orderField:reverse">
<tr><td>{{customer.FirstName}}<td>{{customer.Age}}
</tbody>
</table>
fiddle在小提琴中,为简单起见,我没有包含FullName列.
