左側的賦值無效。（第1行）

我正在製作一個AdWords腳本（它使用javascript）並給我出現此錯誤："Invalid assignment left-hand side. (line 1)"。我找不到錯誤。請幫忙？由於左側的賦值無效。（第1行）

function main() { 
    var todayDate = getDateString(new Date(),'H'); 
    Logger.log('Son las '+todayDate+' horas'); 
    if (todayDate = 11) { 
     var spreadsheet = SpreadsheetApp.create("CPC Log "+getDateString(new Date(), 'dd-MM-yy')); 
     var sheet = spreadsheet.getActiveSheet(); 
     var report = AdWordsApp.report("SELECT CampaignName, AdGroupName, KeywordMaxCpc FROM ADGROUP_PERFORMANCE_REPORT DURING TODAY"); 
     report.exportToSheet(sheet); 
     var expectedRatio = 30; 
     var CpcMultiplier = 1.2; 
     CPCmodifier(expectedRatio,sheet,CpcMultiplier); 
    } 
}

我想補充的完整代碼，如果有人需要看一看吧：

function main() { 
    var todayDate = getDateString(new Date(), 'H'); 
    Logger.log('Son las ' + todayDate + ' horas'); 
    if (todayDate == 11) { 
     var spreadsheet = SpreadsheetApp.create("CPC Log " + getDateString(new Date(), 'dd-MM-yy')); 
     var sheet = spreadsheet.getActiveSheet(); 
     var report = AdWordsApp.report("SELECT CampaignName, AdGroupName, KeywordMaxCpc FROM ADGROUP_PERFORMANCE_REPORT DURING TODAY"); 
     report.exportToSheet(sheet); 
     var expectedRatio = 30; 
     var CpcMultiplier = 1.2; 
     CPCmodifier(expectedRatio, sheet, CpcMultiplier); 
    } 
} 

function getDateString(date, format) { 
    return Utilities.formatDate(new Date(date), AdWordsApp.currentAccount().getTimeZone(), format); 
} 

function CPCmodifier(ratio, sheet, CpcMultiplier) { 
    var CampaignIterator = AdWordsApp.campaigns().withCondition("Status = PAUSED").get(); 
    while (CampaignIterator.hasNext()) { 
     var campaign = CampaignIterator.next(); 
     var campaignName = campaign.getName(); 
     var campaignBudget = campaign.getBudget(); 
     var campaignSpent = campaign.getStatsFor("TODAY").getCost(); 
     var campaignSpentRatio = (campaignSpent/campaignBudget) * 100; 
     Logger.log("La campaña " + campaignName + " lleva gastados $" + campaignSpent + " sobre un presupuesto de $" + campaignBudget + ". Esto representa el " + campaignSpentRatio + "%."); 
     if (campaignSpentRatio < ratio) { 
      var adGroupIterator = AdWordsApp.adGroups().withCondition("Status = ENABLED").withCondition("CampaignName = '" + campaignName + "'").get(); 
      while (adGroupIterator.hasNext()) { 
       var adGroup = adGroupIterator.next(); 
       var adGroupName = adGroup.getName(); 
       for (var row = 2; row > 1; row++) { 
        var cName = sheet.getRange("A" + row).getValue(); 
        var agName = sheet.getRange("B" + row).getValue(); 
        if (cName == '') break; 
        if (cName == campaignName && agName = adGroupName) { 
         var agMaxCpc = sheet.getRange("C" + row).getValue(); 
         if (agMaxCpc == '--') { 
          Logger.log("El grupo de anuncios " + adGroupName + "(campaña " + campaignName + ") no tiene CPC definido. No se aplicarán modificaciones."); 
          break; 
         } else { 
          var agNewCpc = agMaxCpc * CpcMultiplier; 
          Logger.log("El CPC Máximo predeterminado del grupo de anuncios " + adGroupName + "(campaña " + campaignName + ") es de " + agMaxCpc + ". Cambiándolo a " + agNewCpc); 
          break; 
         } 
        } 
       } 
       adGroup.setKeywordMaxCpc(agNewCpc); 
      } 
     } 
    } 
}

解決：

我發現這一點：

if (cName == campaignName && agName **=** adGroupName) {

，它應該是：

if (cName == campaignName && agName == adGroupName) {

'如果（todayDate = 11）'：這是分配;使用'=='（或'==='）進行比較。 – iamnotmaynard

這是你唯一的錯誤嗎？這是完整的代碼嗎？ – iamnotmaynard

是否有另一個在此之前導入的腳本？ – Pointy

錯字：

替換：

if (todayDate = 11) { // That's an assignment

隨着：

if (todayDate == 11) { // That's an "equals" operator

我同意這是一個嚴重的問題，但我不認爲這會導致他/她得到的錯誤。 – Pointy

嗨！我做了這個替換，但錯誤不會消失 –

@ user1475216：你是否發佈了所有相關的代碼？您提供的其他代碼不應引起問題。 – Cerbrus
