下面是我的代码,其中 getJSON 方法不起作用
function loadJson() {
$(document).ready(function () {
alert("inside");
var chart;
var url = "values.json";
var seriesData = [];
var xCategories = [];
var i, cat;
alert("outside");
$.getJSON(url, function (data) {
alert("inside JSON function");
for (i = 0; i < data.length; i++) {
cat = '' + data[i].period_name;
if (xCategories.indexOf(cat) === -1) {
xCategories[xCategories.length] = cat;
}
}
for (i = 0; i < data.length; i++) {
if (seriesData) {
var currSeries = seriesData.filter(function (seriesObject) {
return seriesObject.name == data[i].series_name;
}
);
if (currSeries.length === 0) {
seriesData[seriesData.length] = currSeries = { name: data[i].series_name, data: [] };
} else {
currSeries = currSeries[0];
}
var index = currSeries.data.length;
currSeries.data[index] = data[i].period_final_value;
}
else {
seriesData[0] = { name: data[i].series_name, data: [data[i].period_final_value] }
}
}
//var chart;
//$(document).ready(function() {
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'bar'
},
title: {
text: 'Stacked column chart'
},
xAxis: {
categories: xCategories
},
yAxis: {
//min: 0,
//max: 100,
title: {
text: 'Total fruit consumption'
},
stackLabels: {
enabled: false,
style: {
fontWeight: 'bold',
color: (Highcharts.theme && Highcharts.theme.textColor) || 'gray'
}
}
},
legend: {
align: 'right',
x: -100,
verticalAlign: 'top',
y: 20,
floating: true,
backgroundColor: (Highcharts.theme && Highcharts.theme.legendBackgroundColorSolid) || 'white',
borderColor: '#CCC',
borderWidth: 1,
shadow: false
},
tooltip: {
formatter: function () {
return '<b>' + this.x + '</b><br/>' +
this.series.name + ': ' + this.y + '<br/>'
}
},
series: seriesData
});
});
});
}
在 url 中, values.json 是我的 JSON 文件,如下所示
[{"series_name":"Actual","period_name":"Q1 / 2013","period_final_value":17},
{"series_name":"Actual","period_name":"Q2 / 2013","period_final_value":15},
{"series_name":"Actual","period_name":"Q3 / 2013","period_final_value":13},
{"series_name":"Actual","period_name":"Q4 / 2013","period_final_value":19},
{"series_name":"Alarm","period_name":"Q1 / 2013","period_final_value":14.103},
{"series_name":"Alarm","period_name":"Q2 / 2013","period_final_value":14.404499999999999},
{"series_name":"Alarm","period_name":"Q3 / 2013","period_final_value":14.966999999999999},
{"series_name":"Alarm","period_name":"Q4 / 2013","period_final_value":50},
{"series_name":"Target","period_name":"Q1 / 2013","period_final_value":15.67},
{"series_name":"Target","period_name":"Q2 / 2013","period_final_value":16.005},
{"series_name":"Target","period_name":"Q3 / 2013","period_final_value":16.63},
{"series_name":"Target","period_name":"Q4 / 2013","period_final_value":100}]
文件渲染但数据未显示在图表上,只有 getJSON 方法之外的警报有效,内部警报无效,如果我尝试从 html 页面运行相同的代码,那么它工作正常,但现在我已经编写了整个代码在 ASP.NET Web 应用程序中的 VS 中,我在 javascript 中调用 body onLoad 上的 loadJson 函数,如下所示,
<body onload="loadJson();">
但该方法没有运行,无法解决这个问题,任何帮助将不胜感激......
----------补充工作------
当我在 getJSON 方法上方的任何变量中添加我的 JSON 数据并消除 getJSON 方法并访问它时,我会正确获得 Graph 但是当我使用 getJSON 方法时,它就不起作用
------错误检查---------
我检查了 chrome 中的错误,我知道它无法获取 json 文件,我将 JSON 文件保存在项目文件夹中,然后我也尝试将 json 文件保存在 localhost 中,仍然说同样的错误..
现在我在想我在使用 aspx 页面处理 mime 类型时遇到了问题。有什么可以与之链接的吗??
