[英]Why can't I draw a line on this D3.js using angular code?
我正在嘗試在我的網頁上使用D3.js圖形庫為 Javascript 繪制圖形。 我可以使用 HTML 在 SVG 上畫一條線。 但是當我嘗試使用 javascript 畫一條線時,我得到: ReferenceError: d3 is not defined
即使我已經包含了 D3.js 文件,我也得到了這個。
請告訴我如何解決這個問題。

以下是我的文件供您參考。
Javascript:
myApp = angular.module('myApp', ['ui.router'] );
myApp.config(function($stateProvider, $urlRouterProvider, $locationProvider) {
$stateProvider.state('myState', {url: '/myState', params: {slug: {value: null, squash: true} }, templateUrl: 'my-state-page1.html', controller: 'MyStateCtrl'} );
}
);
myApp.controller('MyStateCtrl', function($scope, $http) {
var self = this;
$scope.$watch(function() {return self.myDataFromAPI}, function (objVal) {
console.log('objVal = ', objVal);
x = objVal.origin.split('.');
console.log("X = ", x)
var svgContainer = d3.select("body") .append("svg") .attr("width", 1000) .attr("height", 1000);
var line = svgContainer.append("line") .attr("x1", x[0]) .attr("y1", x[1]) .attr("x2", x[2]) .attr("y2", x[3]) .attr("stroke-width", 2) .attr("stroke", "black");
},
true
);
self.httpFailure = function(response) {
console.log('Failure');
self.myDataFromAPI = null;
}
self.httpSuccess = function(response) {
console.log('\n\n\nGot the data from the API!');
self.myDataFromAPI = response.data;
console.log('\n\n\self.myDataFromAPI =', self.myDataFromAPI);
}
$http.get(
'https://httpbin.org/get'
).then(self.httpSuccess, self.httpFailure);
}
);
myApp.directive('mypMyDirective',function(){
return {
restrict:'E',
scope: {
myDataFromAPI: '='
},
controller: 'MyStateCtrl',
controllerAs: 'myStateCtrl',
bindToController: true,
templateUrl: 'myD3Diagram.html'
};
}
);

問題是您正在訪問非 https 庫。
<script src="http://d3js.org/d3.v3.min.js" charset="utf-8"></script>
應該是
<script src="https://d3js.org/d3.v3.min.js" charset="utf-8"></script>
