下面小编就为大家带来一篇aspx后台传递Json到前台的两种接收方法推荐。小编觉得挺不错的，现在就分享给大家，也给大家做个参考。一起跟随小编过来看看吧
第一种：前台接收
dataType: "json",
success: function (data)
{
var varReceiver = data;
}

<!-- 引入 ECharts 文件 -->

<form id="form1" runat="server">
<!-- 为 ECharts 准备一个具备大小（宽高）的Dom -->
<div id="main" style="width:1000px;height:400px;">
</div>
<script type="text/javascript">
var varAxis;
var varSeries;
//var varRtcNO = $("#txtHid").val();
var varRtcNO = "35000002818";
var jdata;
var myChart = echarts.init(document.getElementById('main'));
// 显示标题，图例和空的坐标轴
myChart.setOption({
title: {
text: '温度曲线图'
},
tooltip: {
trigger: 'axis',
axisPointer: {
animation: false
},
formatter: function (params) {
return params[0].name + '<br />温度:' + params[0].value + '°C';
}
},
legend: {
data: ['温度']
},
xAxis: {
data: []
},
yAxis: {
axisLabel: {
formatter: '{value} °C'
},
min: 18,
max:30
},
series: [{
name: '温度',
type: 'line',
smooth: true,
data: []
}]
});
// 异步加载数据
$.ajax({
type: "post",
url: "getrtchistorydata.ashx?rtcno=" + varRtcNO,
dataType: "json",
success: function (data) {
var varReceiver = data;
//var varReceiver = jQuery.parseJSON(data);
var varAxis=new Array() ;
var varSeries = new Array(varReceiver.Count[0].total);
for (var i = 0; i < varReceiver.Count[0].total; i++) {
varAxis.push(varReceiver.Rows[i].RecordTime);
varSeries[i] = varReceiver.Rows[i].RoomTemp;
}
// 填入数据
myChart.setOption({
xAxis: {
data: varAxis
},
series: [{
//根据名字对应到相应的系列
name: '温度',
data: varSeries
}]
});
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert(errorThrown);
}
});
</script>
</form>
</body>
</html>
第二种：前台接收
dataType: "text",
success: function (data) {
//var varReceiver = data;
var varReceiver = jQuery.parseJSON(data);
