由JSON.parse引發的意外令牌e

我想從使用FileReader的文件中讀取JSON對象。此JSON文件包含以下：由JSON.parse引發的意外令牌e

{"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":"" 
     }, 
] }

這是我所編寫的代碼：

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.'); 
     }

的JSONObject印通過的console.log（）：

{"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":""},] }

「未捕獲的SyntaxError ：調用JSONView（）時引發意外的令牌e'。

有人可以指出代碼有什麼問題嗎？謝謝。

你在混合一個對象（這就是「json」來自的地方 - 它意味着「JavaScript Object Notation」，因爲對象是javascript本身的）和一個字符串（你不能在對象上使用'.replace'）。任何不帶引號的'new'都不是有效的JSON，但它是一個有效的javascript對象。 – h2ooooooo

這對初學者來說是無效的JSON。這些位：new GLatLng(40.266044,-74.718479)

...不能是JavaScript類的構造函數;將它們更改爲the JSON spec中定義的類型之一。

..或布爾值，NULL，整數或浮點數以及子對象。 – h2ooooooo

哦..我只是試圖作爲一個例子..我搜索了JSON文件，這是什麼出現。感謝您指出了這一點！ – user2522981

@ h2ooooooo哈哈是啊我正在令人難以置信的懶惰。固定。 – brandonscript
