问题描述
我们正在使用 Angular-ui-router 用于我们的应用状态管理.
We're using Angular-ui-router for our app state management.
我们遇到的一个问题是,当 $state
更改时,每个组件都会刷新,即使它是更新的变量,但在某些组件中不存在/未使用.
A problem we're having is that every component refreshes when the $state
changes, even if it's a variable that is updated that does not exist/not used in some components.
例如,我们有一个 TickersPanel 和一个 TagsPanel.当一个 Ticker 被选中时,TickersPanel 应该被更新和刷新,但是当在 TagsPanel 中选择一个标签时,TickersPanel 不应该刷新,但它目前会刷新.
For example, we have a TickersPanel and a TagsPanel. When a Ticker is selected, the TagsPanel should be updated and refreshed, however when a tag is selected in the TagsPanel, the TickersPanel should NOT refresh, but it currently does.
我发现 { notify: false }
是另一个可以传入的对象.但是一旦我这样做,任何组件都不会刷新.
I found out that { notify: false }
is another object that can be passed in. However once I do that, NO components will refresh.
const save = (tag, terms) => {
CONTAINER.push(tag);
$state.go('charting', Term.write(terms), { notify: false }).then((stateResult) => {
console.log('stateResult', stateResult);
});
};
有没有人找到解决这个问题的方法?
TagsPanel $onInit(在每次 $state 变化时运行)
this.$onInit = () => {
tagsCol.addEventListener('scroll', scrollingTags);
this.tags = [];
this.limit = 30;
const panelOpen = Dashboard.panelStatus(this.tagsOpen, this.chartMax);
panelOpen ? buildTagList() : collapsePanel();
};
TickersPanel $onInit (在每次 $state 改变时运行,如果 $state.params.ticker
没有改变,那么不应该运行)
TickersPanel $onInit (Runs on every $state change, if $state.params.ticker
did not change, then this should not be ran)
this.$onInit = () => {
this.tickers = [];
this.spy = {
longname: "SPDR S&P 500",
ticker: "SPY",
};
this.showTickersPanel = Dashboard.panelStatus(this.tagsOpen, this.chartMax);
// const currentState = $state.params;
// const prevState = Dashboard.getPreviousState();
loadTickers().then(() => this.loadingTickersDone = true);
};
推荐答案
我制作了一个 JsFiddle 描述一种使用 uiRouter 实现我从您的问题中了解到的内容的方法.
I've made a JsFiddle to describe a way to achieve what I've understood from your question using the uiRouter.
小提琴使用状态继承 和 命名视图 仅重新初始化tags
在 tickers
参数改变时的状态.
The fiddle uses state inheritance and named views to only reinitialize the tags
state when the tickers
param changes.
[..]
// Using @ on the view names to refer to the absolute uiViews.
$stateProvider.state('tickers', {
url: "",
views: {
'tickersPanel@': {
template: [..]
bindToController: true,
controllerAs: "$ctrl",
controller: function() {
this.$onInit = function() {
console.info('Tickers Panel $onInit');
this.tickers = ["Ticker1", "Ticker2", "Ticker3"]
}
}
},
[..]
}
});
$stateProvider.state('tags', {
parent: 'tickers',
url: "/:ticker",
views: {
'tagsPanel@': {
template: [..]
controllerAs: '$ctrl',
bindToController: true,
controller: function($stateParams) {
this.$onInit = function() {
console.info('Tags Panel 2 $onInit');
this.ticker = $stateParams["ticker"];
}
}
}
}
});
