tl; dr:GraphStore的UUID在每次向它添加新圖時發生變化。這導致我假設每個Graph都創建了自己獨特的GraphStore。我希望他們都分享一個商店。我有一個包含多個Graph組件的React Dashboard組件。迴流:有多個組件訪問相同的商店
我的Graph組件從儀表板傳遞了一個id道具。然後使用該ID,查找存儲在GraphStore中的圖形數組中的數據。但是,在我看來,每個Graph都創建了自己的GraphStore,而不是所有的共享相同的(所需的行爲)。我如何讓它們都使用相同的GraphStore?
我想過要從儀表板傳入正確的GraphStore,但是我不可能讓每個Graph都監聽GraphStore的更改。
我很高興不使用Reflux.connectFilter,但它似乎是完美的東西。
我的代碼(至少關鍵部位):
控制板
var React = require('react');
var Graph = require('./graph').Graph;
var GraphActions = require('./graphActions').GraphActions;
var UUID = require('uuid');
var Dashboard = React.createClass({
...
render: function() {
var graphs = [];
for(var i = 0; i < 10; ++i) {
var id = UUID.v4();
GraphActions.createGraph(id);
graphs.push(
<Graph id={id} />
);
}
}
});
module.exports = {Dashboard: Dashboard};
格拉夫
var React = require('react');
var GraphStore = require('./graphStore').GraphStore;
var Graph = React.createClass({
mixins: [Reflux.connectFilter(GraphStore, "graph", function(){
return graphs.filter(function(graph) {
return graph.id === this.props.id;
}.bind(this))[0];
})],
propTypes: {
id: React.PropTypes.string
},
render: function() {
// Needed because the AJAX call in GraphStore might not have completed yet
if(typeof this.state.graph == "undefined") {
return (<div>Graph loading...</div>);
}
return (<div>Data: {this.state.graph.data}</div>);
}
});
module.exports = {Graph: Graph};
GraphStore
var Reflux = require('reflux');
var jQuery = require('jquery');
var GraphActions = require('./graphActions').GraphActions;
var UUID = require('uuid');
var GraphStore = Reflux.createStore({
listenables: [GraphActions],
onCreateGraph: function(graphId) {
console.log("GraphStore " + this.id + " is adding new graph " + graphId);
jQuery.ajax({
...
success: this.addGraph
});
},
addGraph: function(data) {
this.graphs.push(
{
id: graphId,
data: data
}
);
this.trigger({graphs: this.graphs});
},
getInitialState: function() {
this.graphs = [];
// Here I give the store a UUID so I can identify it later
this.id = UUID.v4();
return {
graphs: this.graphs
};
}
});
這也解釋了這麼多,謝謝大家! – 2015-04-02 12:44:49
很高興能幫到你:) – 2015-04-02 12:56:24
