私はangular-treeview directiveを使用しています。ここで、ツリーを読み込むのに時間がかかるので、その時間のスピナーを表示したいと思います。ですから、私はディレクティブで変数を定義したいと思っています。その変数はビューに使用され、スピナーを表示することができます。ディレクティブのスコープを定義し、ビューで使用する
**angular-treeview.js**
(function (angular) {
'use strict';
angular.module('angularTreeview', []).directive('treeModel', ['$compile', function($compile) {
return {
restrict: 'A',
link: function (scope, element, attrs) {
//tree id
var treeId = attrs.treeId;
//tree model
var treeModel = attrs.treeModel;
//node id
var nodeId = attrs.nodeId || 'id';
//node label
var nodeLabel = attrs.nodeLabel || 'label';
//node class
var nodeClass = attrs.nodeClass || 'type';
//children
var nodeChildren = attrs.nodeChildren || 'children';
//search by label
var searchQuery = attrs.searchQuery || '';
//function for highlighting search text
var searchHighlightFunction = attrs.searchHighlightFunction ||
function (content, text) {
return content
};
//css class to be added for highlighting
var searchHighlightClassName = attrs.searchHighlightClassName || '';
//filter to be used with search query
var searchFilter = attrs.searchFilter || '';
//tree template
var template =
'<ul>' +
'<li data-ng-repeat="node in ' + treeModel + '| ' + searchFilter + ':' + searchQuery + '" data-ng-init="node.collapsed=true">' +

//check tree id, tree model
if(treeId && treeModel) {

scope.$watch(searchQuery, function (newVal, oldVal) {
var node = scope.node;

//root node
if(attrs.angularTreeview) {

私のhtmlがある - そう
<div data-angular-treeview="true" data-tree-id="Treevalue"
data-tree-model="suggestionList" data-node-id="id" data-node-class="type" data-node-label="name"
data-node-children="childrens" data-search-query="suggestionListSearchText" data-search-highlight-function="highlightHTML"
data-search-highlight-class-name="searchText" data-search-filter="NameFilter">
</div>
、このディレクティブで変数を定義し、スコープでそれを使用する方法は？
ディレクティブ –
内の範囲を分離してみてください私はディレクティブで分離されたスコープを使用する場合、それはツリーを表示していなかった、このことを試みたが、しています。 –
