JSON.parse 抛出的意外令牌 e

Question

我正在尝试使用 FileReader 从文件中读取 JSON 对象。此 json 文件包含以下内容：

{"markers": [
        {
            "point":new GLatLng(40.266044,-74.718479), 
            "homeTeam":"Lawrence Library",
            "awayTeam":"LUGip",
            "markerImage":"images/red.png",
            "information": "Linux users group meets second Wednesday of each month.",
            "fixture":"Wednesday 7pm",
            "capacity":"",
            "previousScore":""
        },
        {
            "point":new GLatLng(40.211600,-74.695702),
            "homeTeam":"Hamilton Library",
            "awayTeam":"LUGip HW SIG",
            "markerImage":"images/white.png",
            "information": "Linux users can meet the first Tuesday of the month to work out harward and configuration issues.",
            "fixture":"Tuesday 7pm",
            "capacity":"",
            "tv":""
        },
        {
            "point":new GLatLng(40.294535,-74.682012),
            "homeTeam":"Applebees",
            "awayTeam":"After LUPip Mtg Spot",
            "markerImage":"images/newcastle.png",
            "information": "Some of us go there after the main LUGip meeting, drink brews, and talk.",
            "fixture":"Wednesday whenever",
            "capacity":"2 to 4 pints",
            "tv":""
        },
] }

这是我写的代码：

var jsonClean = function(jsonText)  {
            return jsonText.replace(/\n/g, "").replace(/\r/g, "").replace(/\t/g, "");
        };

        if (window.File && window.FileReader && window.FileList && window.Blob) {
            console.log('Uploading...');
            var uploader = ($('input#fileUpload'))[0];
            var fileList = uploader.files;
            console.log(fileList.length);
            if(fileList.length > 0){
                var reader = new FileReader();
                reader.addEventListener('load',function(loadEvent){
                    if(reader.readyState == FileReader.DONE){
                        var jsonObject = jsonClean(reader.result);
                        console.log(jsonObject);
                        $('#jsonView').empty();
                        $('#jsonView').JSONView(JSON.parse(jsonObject));
                      }
               });
                    reader.readAsText(fileList[0]);

                }
            } 
    else {
          alert('The File APIs are not fully supported in this browser.');
        }

jsonconsole.log() 打印的对象:

{"markers": [{"point":new GLatLng(40.266044,-74.718479), "homeTeam":"Lawrence Library","awayTeam":"LUGip","markerImage":"images/red.png","information": "Linux users group meets second Wednesday of each month.","fixture":"Wednesday 7pm","capacity":"","previousScore":""},{"point":new GLatLng(40.211600,-74.695702),"homeTeam":"Hamilton Library","awayTeam":"LUGip HW SIG","markerImage":"images/white.png","information": "Linux users can meet the first Tuesday of the month to work out harward and configuration issues.","fixture":"Tuesday 7pm","capacity":"","tv":""},{"point":new GLatLng(40.294535,-74.682012),"homeTeam":"Applebees","awayTeam":"After LUPip Mtg Spot","markerImage":"images/newcastle.png","information": "Some of us go there after the main LUGip meeting, drink brews, and talk.","fixture":"Wednesday whenever","capacity":"2 to 4 pints","tv":""},] }

'Uncaught SyntaxError:Unexpected token e' 在调用 JSONView() 时抛出。

有人可以指出代码有什么问题吗？谢谢。

Answer 1

这对初学者来说是无效的 JSON。这些位：new GLatLng(40.266044,-74.718479)

...不能是 JavaScript class 构造函数；将它们更改为 the JSON spec 中定义的类型之一。
