使用數組推動獲得額外的括號

Question

我想建立一個小的自定義記錄器，我注意到我的數組推動，我得到額外的括號，並不知道發生了什麼。下面是示例輸出

{ 
"GuestCheckout": [ 
    { 
     "log": "Product Id: 78-1212121", 
     "screenshot": "" 
    }, 
    [ 
     { 
      "log": "Product Color: undefined Product Size: 6 Lb Qty: 2", 
      "screenshot": "" 
     } 
    ], 
    [ 
     { 
      "log": "", 
      "screenshot": "results/screenshots/Guest Checkout - Failed.jpg" 
     } 
    ] 
] 
} 

這裏是具有記錄功能

var logs = {}, 
curLogs = []; 

module.exports = { 
    logger: function(log, screenshot) { 
     isScreenshot = screenshot || "false"; 
     curTestName = testName.replace(/ /g,''); 
     curLogs = []; 

     if (isScreenshot == "true") { 
     curLogs.push({ 
      "log": "", 
      "screenshot": log 
     }); 
     } else { 
     curLogs.push({ 
      "log": log, 
      "screenshot": "" 
     }); 
     } 

     if (curTestName in logs) { 
     logs[curTestName].push(curLogs); 
     } else { 
     logs[curTestName] = curLogs; 
     } 

     console.log(curLogs); 
    } 
} 

您將與第一個日誌和截圖注意它的周圍{}包裹，但與包裹第二實例類[]。這個記錄器功能被多次調用。我認爲這與推動建設這種方式有關，但我可能是錯的。由於

UPDATE：有了一個解決方案輸出看起來現在這個樣子

{ 
    "GuestCheckout": [ 
    [ 
     { 
      "log": "Product Id: 36-5173230", 
      "screenshot": "" 
     } 
    ], 
    [ 
     { 
      "log": "Product Color: undefined Product Size: 6 Lb Qty: 2", 
      "screenshot": "" 
     } 
    ], 
    [ 
     { 
      "log": "", 
      "screenshot": "results/screenshots/Guest Checkout - Failed.jpg" 
     } 
    ] 
    ] 
} 

現在的問題是所有{日誌，截圖}被包裹在括號內。

Answer 1

當您將某些內容記錄到已存在的測試中時，就會出現該問題。如果日誌已經存在，那麼就是推送一個數組而不是一個對象。要解決這個問題，你有兩個選擇。爲測試拉動現有陣列並直接推送它，或者，將每個新日誌條目推後。

var logs = {}, 
curLogs = []; 

module.exports = { 
    logger: function(log, screenshot) { 
     isScreenshot = screenshot || "false"; 
     curTestName = testName.replace(/ /g,''); 
     if (!logs[curTestName]) { 
     // initialize logs entry 
     logs[curTestName] = []; 
     } 
     // get logs entry 
     curLogs = logs[curTestName]; 

     if (isScreenshot == "true") { 
     curLogs.push({ 
      "log": "", 
      "screenshot": log 
     }); 
     } else { 
     curLogs.push({ 
      "log": log, 
      "screenshot": "" 
     }); 
     } 
     console.log(curLogs); 
    } 
} 

或

var logs = {}, 
curLogs = []; 

module.exports = { 
    logger: function(log, screenshot) { 
     isScreenshot = screenshot || "false"; 
     curTestName = testName.replace(/ /g,''); 
     curLogs = []; 

     if (isScreenshot == "true") { 
     curLogs.push({ 
      "log": "", 
      "screenshot": log 
     }); 
     } else { 
     curLogs.push({ 
      "log": log, 
      "screenshot": "" 
     }); 
     } 

     if (curTestName in logs) { 
     Array.push.apply(logs[curTestName], curLogs); 
     } else { 
     logs[curTestName] = curLogs; 
     } 

     console.log(curLogs); 
    } 
}

您將carlog定義爲數組。在第一步中，您將對象推送到數組。這就是爲什麼沒有[]。在第二和第三步中，您將數組推送到carlog。這就是爲什麼有[]。
