我创建了一个显示图表的简单指令。角度js指令作用域值与控制器绑定undefined
我有一个$ http请求的角度指令。我必须将响应存储到我的$ scope中,并将此$ scope值存储到我的链接指令范围中以显示图表。
我试图使用上午图表角度图
这里实施轨距图表是我的代码:
app.directive('gauge',function(){
return {
restrict: 'AEC',
replace:true,
template: '<div id="speeda_meter"></div>',
scope: {ranges:'='},
controller: function ($scope, $http,apiurl) {
$scope.type = 'percentage';
function getUsage(type){
$http({
method: 'POST',
url: apiurl + '/getUsage',
data: {'type': $scope.type}
}).success(function (data, status) {
if (data.status == true) {
$scope.ranges = data.result.ranges;
$scope.interval = data.result.interval;
}
});
}
getUsage($scope.type);
},
link: function (scope, element, attrs,ctrl) {
var chart = false;
// ngModelCtrl.$formatters.push(function(modelValue) {
// return modelValue;
// });
// ngModelCtrl.$render = function() {
//scope.ranges = ngModelCtrl.$viewValue;
console.log(ctrl.ranges);
var initChart = function() {
if (chart) chart.destroy();
var config = scope.config || {};
chart = AmCharts.makeChart("speeda_meter", {
"type": "gauge",
"axes": [ {
"axisThickness": 0,
"axisAlpha": 0.2,
"tickAlpha": 0.2,
"valueInterval": 425,
"inside": false,
"fontSize": 11,
"gridInside": true,
"startAngle": -90,
"endAngle": 90,
"bands": scope.ranges,
"topText": "497",
"topTextYOffset": 105,
"topTextColor": "#555555",
"topTextFontSize": 50,
"bottomText": "Watts",
"bottomTextYOffset": -10,
"bottomTextColor": "#909090",
"bottomTextFontSize": 18,
"endValue": 1700
}],
"arrows": [{
"startWidth" : 15,
"nailBorderThickness" : 1,
"nailRadius" : 8 ,
"color" : "#5b5b5b",
}],
"export": {"enabled": true}
});
};
initChart();
// }
}
}
});
<gauge ranges="ranges" interval="interval"></gauge>
我试图范围和间隔与所述响应于在所述链路分配范围,但它是未定义的。那有什么问题?
任何解决方案?
