我正在尝试运行此函数来获取JSON数据并在图表上绘制。我已经获得了JSON,但是在成功之后:AJAX调用我插入了一个警报并且不知何故没有被击中。
任何人都可以告诉我我哪里出错了
这是我的JSON
{
"t": "radioiodine",
"y": 50,
"x": "2014-04-04"
}{
"t": "radioiodine",
"y": 50,
"x": "2013-06-09"
}{
"t": "radioiodine",
"y": 100,
"x": "2012-03-05"
}{
"t": "radioiodine",
"y": 200,
"x": "2008-05-04"
}{
"t": "radioiodine",
"y": 100,
"x": "2006-02-17"
}{
"t": "radioiodine",
"y": 50,
"x": "2002-03-31"
}{
"t": "radioiodine",
"y": 100,
"x": "2001-02-23"
}{
"t": "radioiodine",
"y": 50,
"x": "2000-12-13"
}{
"t": "radioiodine",
"y": 100,
"x": "2000-04-06"
}
这是我的代码
$(document).ready(function(){
$("#find").click(function(e){
e.preventDefault();
$.ajax({
// the URL for the request
url: "getrad.php",
// the data to send (will be converted to a query string)
data: {pnhsno: $('#search').val()},
// whether this is a POST or GET request
type: "GET",
// the type of data we expect back
dataType : "json",
// code to run if the request succeeds;
// the response is passed to the function
success: function(json){
alert("start");
if(json.length !=0 ){
var dataPoints = json.map(function (p) {
p.x = new Date(p.x);
return p;
});
//var dp1 = [];
//var lt1;
//for(var i=0; i<dataPoints.length; i++){
// if(dataPoints[i].t =="radioiodine"){
// lt1 =dataPoints[i].t;
// dp1.push({x:dataPoints[i].x, y:dataPoints[i].y})}
//}
// $("#radioiodine").CanvasJSChart({ //Pass chart options
// title:{text:"Radioiodine Dosage"},
// zoomEnabled: true,
// panEnabled: true,
// axisX:{valueFormatString:"DD-MM-YYYY",labelAngle:-45},
//
// data: [
// {
// type: "column",
// legendText:lt1,
// showInLegend:true,
// dataPoints:dp1
// }]});
}//if
//else{ $("#radioiodine").html("No Data For Radioiodine Found");}
}//json
});
});
});
答案 0 :(得分:2)
因为您提供的json格式无效。有效的JSON将如下所示:
[{
"t": "radioiodine",
"y": 50,
"x": "2014-04-04"
},{
"t": "radioiodine",
"y": 50,
"x": "2013-06-09"
},{
"t": "radioiodine",
"y": 100,
"x": "2012-03-05"
},{
"t": "radioiodine",
"y": 200,
"x": "2008-05-04"
},{
"t": "radioiodine",
"y": 100,
"x": "2006-02-17"
},{
"t": "radioiodine",
"y": 50,
"x": "2002-03-31"
},{
"t": "radioiodine",
"y": 100,
"x": "2001-02-23"
},{
"t": "radioiodine",
"y": 50,
"x": "2000-12-13"
},{
"t": "radioiodine",
"y": 100,
"x": "2000-04-06"
}]
最有可能的是,success
没有被击中,因为你的ajax调用永远不会成功。
