方式一:setJSONUrl
function initChart() {
var myChart = new FusionCharts("FusionCharts/Line.swf", "myChartId", "100%", "100%", "0", "1");
var url = '${pageContext.request.contextPath}/enterleaveinfoAction!realtimeCarEnterinfoChart.action?carDate=2013-0=11-28';
myChart.setJSONUrl(url);
myChart.render("chartContainer");
}
问题：第一次页面加载没问题，后续刷新时会出现 no data to display，据说是跟渲染没完成重新请求数据有关。
方式二:setJSONData
function initChart() {
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "${pageContext.request.contextPath}/enterleaveinfoAction!realtimeCarEnterinfoChart.action?carDate=2013-0=11-28",
data: "{}",
dataType: 'json',
success: function (json) {
var myChart = new FusionCharts("FusionCharts/Line.swf", "myChartId", "100%", "100%", "0", "1");
myChart.setJSONData(json);
myChart.render("chartContainer");
},
error: function (xhr) { //如果没有上面的捕获出错会执行这里的回调函数
alert('页出错\n\r' + xhr.responseText);
}
});
}
