我需要帮助解决这个错误：
Uncaught SyntaxError: Unexpected end of JSON input at JSON.parse () at Object.success (dashboard.js:22) at fire (jquery-3.3.1.js:3268) at Object.fireWith [as resolveWith] (jquery-3.3.1.js:3398) at done (jquery-3.3.1.js:9305) at XMLHttpRequest. (jquery-3.3.1.js:9548)
我尝试使用 JSON.parse() 将字符串转换为 JSON 对象，导致了这个错误。我正在使用 OracleJet，以下是我的代码：
function DashboardViewModel() {
var self = this;
self.lineTypeValue = ko.observable('curved');
var scatterSeries = [];
$.getJSON( "http://localhost:8080/points", function (data) {
console.info(data);
var ch = '{"name":"graphe1","items":'+JSON.stringify(data.results[1])+ '}';
console.info(ch);
console.info(JSON.parse(scatterSeries));
scatterSeries.push(JSON.parse(ch));
});
/* chart data */
this.scatterSeriesValue = ko.observableArray(scatterSeries);
self.lineTypeOptions = [
{id: 'straight', label: 'straight'},
{id: 'curved', label: 'curved'},
{id: 'stepped', label: 'stepped'},
{id: 'segmented', label: 'segmented'},
{id: 'none', label: 'none'}
];
}
从 "http://localhost:8080/points" 得到的 JSON 数据看起来像这样：
{ "results":[
[
{
"b":"0.110547334",
"cost":"0.000000",

我希望变量scatterSeries保存的内容是像这个表格一样的表格：
[ {
name:"graphe1",
items:[
{
x:8,
y:2
},
{
x:15,
y:15
},
{
x:25,
y:26
},
{
x:33,
y:22
},
{
x:36,
y:40
}
]},]
我在控制台上得到的关于字符串ch的内容是这样的：
{"name":"graphe1","items":[{"x":0,"y":0},{"x":1,"y":2},{"x":2,"y":4},{"x":3,"y":6},{"x":4,"y":8},{"x":5,"y":10},{"x":6,"y":12},{"x":7,"y":14},{"x":8,"y":16},{"x":9,"y":18},{"x":10,"y":20},{"x":11,"y":22},{"x":12,"y":24},{"x":13,"y":26},{"x":14,"y":28},{"x":15,"y":30},{"x":16,"y":32},{"x":17,"y":34},{"x":18,"y":36},{"x":19,"y":38},{"x":20,"y":40},{"x":21,"y":42},{"x":22,"y":44},{"x":23,"y":46},{"x":24,"y":48},{"x":25,"y":50},{"x":26,"y":52},{"x":27,"y":54},{"x":28,"y":56},{"x":29,"y":58},{"x":30,"y":60},{"x":31,"y":62},{"x":32,"y":64},{"x":33,"y":66},{"x":34,"y":68},{"x":35,"y":70},{"x":36,"y":72},{"x":37,"y":74},{"x":38,"y":76},{"x":39,"y":78},{"x":40,"y":80},{"x":41,"y":82},{"x":42,"y":84},{"x":43,"y":86},{"x":44,"y":88},{"x":45,"y":90},{"x":46,"y":92},{"x":47,"y":94},{"x":48,"y":96},{"x":49,"y":98},{"x":50,"y":100},{"x":51,"y":102},{"x":52,"y":104},{"x":53,"y":106},{"x":54,"y":108},{"x":55,"y":110},{"x":56,"y":112},{"x":57,"y":114},{"x":58,"y":116},{"x":59,"y":118},{"x":60,"y":120},{"x":61,"y":122},{"x":62,"y":124},{"x":63,"y":126},{"x":64,"y":128},{"x":65,"y":130},{"x":66,"y":132},{"x":67,"y":134},{"x":68,"y":136},{"x":69,"y":138},{"x":70,"y":140},{"x":71,"y":142},{"x":72,"y":144},{"x":73,"y":146},{"x":74,"y":148},{"x":75,"y":150},{"x":76,"y":152},{"x":77,"y":154},{"x":78,"y":156},{"x":79,"y":158},{"x":80,"y":160},{"x":81,"y":162},{"x":82,"y":164},{"x":83,"y":166},{"x":84,"y":168},{"x":85,"y":170},{"x":86,"y":172},{"x":87,"y":174},{"x":88,"y":176},{"x":89,"y":178},{"x":90,"y":180},{"x":91,"y":182},{"x":92,"y":184},{"x":93,"y":186},{"x":94,"y":188},{"x":95,"y":190},{"x":96,"y":192},{"x":97,"y":194},{"x":98,"y":196},{"x":99,"y":198}]}
有人可以帮忙吗？！！:( :(
