我想從jointjs教程中運行示例應用程序,這是迄今爲止我所擁有的。如何將JointJS與流星結合使用?
1)sampleApp.html
<head>
<title>sampleApp</title>
</head>
<body>
<h1>Welcome to Meteor!</h1>
{{> hello}}
</body>
<template name="hello">
<div></div>
</template>
2)sampleApp.js
if (Meteor.isClient) {
Template.hello.onRendered(function() {
var graph = new joint.dia.Graph;
var paper = new joint.dia.Paper({
el: this.$('div'),
width: 600,
height: 200,
model: graph,
gridSize: 1
});
var rect = new joint.shapes.basic.Rect({
position: { x: 100, y: 30 },
size: { width: 100, height: 30 },
attrs: { rect: { fill: 'blue' }, text: { text: 'my box', fill: 'white' } }
});
var rect2 = rect.clone();
rect2.translate(300);
var link = new joint.dia.Link({
source: { id: rect.id },
target: { id: rect2.id }
});
graph.addCells([rect, rect2, link]);
});
}
if (Meteor.isServer) {
Meteor.startup(function() {
// code to run on server at startup
});
}
當我運行此我得到以下錯誤:
遺漏的類型錯誤:_.merge不一個functionjoint.dia.Cell.Backbone.Model.extend.constructor @ joint.js:3831child @ backbone.js:1408(匿名函數)@ joint.js:7436math @ joint.js:39(匿名函數)@joint.js :44(匿名功能)@聯合。 JS 518ac863e9f6f1f9a755394c59ad7d562c084829:11194
與從跟蹤afterFlush功能
異常: 的ReferenceError:接頭不在[對象的對象]中定義 。 (:3000/app/client/meteor:/app/client/sampleApp.js:5)
我已經嘗試在項目根目錄中放置sampleApp.html和sampleApp.js,並且還在/ client joint.js中客戶端/
任何人都已經處理了這個問題或有任何想法如何解決這個ReferenceError?
編輯:這是其中未捕獲的類型錯誤發生JointJS的內容:
// joint.dia.Cell base model.
// --------------------------
joint.dia.Cell = Backbone.Model.extend({
// This is the same as Backbone.Model with the only difference that is uses _.merge
// instead of just _.extend. The reason is that we want to mixin attributes set in upper classes.
constructor: function(attributes, options) {
var defaults;
var attrs = attributes || {};
this.cid = _.uniqueId('c');
this.attributes = {};
if (options && options.collection) this.collection = options.collection;
if (options && options.parse) attrs = this.parse(attrs, options) || {};
if (defaults = _.result(this, 'defaults')) {
//<custom code>
// Replaced the call to _.defaults with _.merge.
attrs = _.merge({}, defaults, attrs);
//</custom code>
}
this.set(attrs, options);
this.changed = {};
this.initialize.apply(this, arguments);
},
ATTRS = _.merge({},缺省值,ATTRS);是引發錯誤的行
從錯誤消息中可以看到Underscore未被加載到頁面上。 jointjs似乎在使用Underscore來處理'_.merge(...)',但沒有找到它。這導致'聯合'沒有被定義,因爲它初始化失敗。這樣簡單嗎? –
_.merge(...)的代碼是Backbone.js的一部分,我沒有觸及,我不確定它引用的是什麼。 – nerfdoit
對於未來的搜索者,Backbone.js確實依賴於單獨提供的Underscore :.從文檔:「骨幹的唯一硬依賴是Underscore.js(> = 1.7.0)。」 –
