我希望高图的标题为$scope.data.title
,但目前属性标题将data.title
解释为字符串并绑定到范围。我已经尝试将"", {{}}
放在data.title .html附近,但它不起作用。我想我错过了别的东西。
的index.html
<test-chart title="{{data.title}}">
<chart-series title="Series 1" type="line">
</chart-series>
<chart-series title="Series 3" type="column">
</chart-series>
</test-chart>
的script.js
.directive('testChart', function() {
return {
restrict: 'E',
transclude: true,
controllerAs:'chartCtrl',
scope: {
},
controller: ['$scope', '$element', '$attrs', function ChartController($scope, $element, $attrs) {
$scope.data = {
title: 'HIGHGRAPH',
series: [{
title: 'series1',
type: 'line',
data: [1,2]
}, {
title: 'series2',
type: 'area',
data: [3,5]
}]
}
var hc = Highcharts.chart('highchart_container', {});
$scope.$watch("data",function(newValue,oldValue) {
hc.update({
title: {
text: newValue.title
}
})
})
this.addSeries = function(a) {
hc.addSeries({
name: a.title,
type: a.type,
data: [1,2,3,4,5,6]
})
};
}],
templateUrl: 'my-tabs.html'
};

这不符合预期,但可以在没有watch
的情况下执行此操作吗?

你不必将s.title放在ng-repeat中。它应该在外面。 这是一个工作片段。: -
var app = angular.module("myApp", []);
app.controller("myCtrl", function($scope) {
});
app.directive('testChart', function() {
return {
restrict: 'E',
transclude: true,
controllerAs:'chartCtrl',
scope: {
},
controller: ['$scope', '$element', '$attrs', function ChartController($scope, $element, $attrs) {
$scope.data = {
title: 'HIGHGRAPH',
series: [{
title: 'series1',
type: 'line',
data: [1,2]
}, {
title: 'series2',
type: 'area',
data: [3,5]
}]
}
var hc = Highcharts.chart('highchart_container', {
title: {
text: $scope.data.title
}
});
this.addSeries = function(a) {
hc.addSeries({
name: a.title,
type: a.type,
data: [1,2,3,4,5,6]
})
};
}],
template: '<div> <p>This is a chart</p><ul> <li ng-repeat="s in series"> </li> </ul> <div id=\'highchart_container\'></div> <ng-transclude></ng-transclude> </div>'
};
})
.directive('chartSeries', function() {
return {
require: '^test-chart',
restrict: 'E',
transclude: true,
scope: {
title: '@'
},
link: function(scope, element, attrs, chartCtrl) {
chartCtrl.addSeries(attrs);
},
};
});

显然这就是你必须这样做的方式。 title
的Highchart文档工作plunker
现在 my-tabs.html
<div>
<div id='highchart_container'></div>
<ng-transclude></ng-transclude>
</div>
和 index.html
<body ng-app="docsTabsExample">
<test-chart>
<chart-series title="Series 1" type="line">
</chart-series>
<chart-series title="Series 3" type="column">
</chart-series>
</test-chart>
</body>
</html>
<强>的script.js 强>
(function(angular) {
'use strict';
angular.module('docsTabsExample', [])
.directive('testChart', function() {
return {
restrict: 'E',
transclude: true,
controllerAs:'chartCtrl',
controller: ['$scope', '$element', '$attrs', function ChartController($scope, $element, $attrs) {
$scope.data = {
title: 'HIGHGRAPH',
series: [{
title: 'series1',
type: 'line',
data: [1,2]
}, {
title: 'series2',
type: 'area',
data: [3,5]
}]
}
var hc = Highcharts.chart('highchart_container', {
title: {
align:"center",
text:$scope.data.title
}
});
this.addSeries = function(a) {
hc.addSeries({
name: a.title,
type: a.type,
data: [1,2,3,4,5,6]
})
};
}],
templateUrl: 'my-tabs.html'
};
})
.directive('chartSeries', function() {
return {
require: '^test-chart',
restrict: 'E',
transclude: true,
scope: {
title: '@'
},
link: function(scope, element, attrs, chartCtrl) {
chartCtrl.addSeries(attrs);
},
};
});
})(window.angular);

如果标题是chartCtrl的范围变量,我无法理解为什么需要数据绑定。
这只是诀窍:
<div>
{{data.title}}
<div id='highchart_container'></div>
<ng-transclude></ng-transclude>
</div>

通过在对象上添加watch
来解决它。
