nknown錯誤：Runtime.evaluate拋出異常：語法錯誤：意外的令牌VAR

Question

我有這樣的代碼：

 JavascriptExecutor javascriptExecutor = (JavascriptExecutor) driver; 
//  javascriptExecutor.executeScript("W.setOffer({offer: {kind: \"coupon\", title: \"Hello\", availability: " + 
//    "\"available\"}},{})"); 

     String script = 
       "var aLocation = {}" + 
         "var aOffer = {}" + 
         "var aAdData = " + 
         "{ " + 
         "location: aLocation, " + 
         "offer: aOffer " + 
         " } " + 

         "var aClientEnv = " + 
         " { " + 
         " sessionid:  「」, " + 
         " cookie:  「」, " + 
         " 「rtserver-id」: 1, " + 
         "  lon:   34.847, " + 
         "  lat:   32.123, " + 
         "  venue:   「」, " + 
         " venue_context: 「」, " + 
         // AD-{"campaignId":8224,"offerId":4172} 
         // see Venue Context for more information. 

         " source:  「」," + // One of the following (string) values: ADS_PIN_INFO, 
         // ADS_0SPEED_INFO, ADS_LINE_SEARCH_INFO, 
         // ADS_ARROW_NEARBY_INFO, ADS_CATEGORY_AUTOCOMPLETE_INFO, 
         // ADS_HISTORY_LIST_INFO 
         // (this field is also called 「channel」) 

         " locale:  「」" + // ISO639-1 language code (2-5 characters), supported formats: 
         // * en/he/fr/… 
         // * en-GB/pt-BR/en_GB/pt_BR 
         // * es-419/es_419 
         " } " + 


         "W.setOffer(aAdData, aClientEnv);"; 

     javascriptExecutor.executeScript(script); 
    } 

，但它的executeScript

org.openqa.selenium.WebDriverException: unknown error: Runtime.evaluate threw exception: SyntaxError: Unexpected token var 
(Session info: chrome=42.0.2298.0) 
    (Driver info: chromedriver=2.9.248307,platform=Mac OS X 10.9.5 x86_64) (WARNING: The server did not provide any stacktrace information) 
Command duration or timeout: 18 milliseconds 

失敗這裏是腳本。我錯過了什麼嗎？

我不能使用var來保存元素嗎？

var aLocation = {} 
var aOffer = {} 
var aAdData = { 
    location: aLocation, 
    offer: aOffer 
} 
var aClientEnv = { 
    sessionid: 「」, 
    cookie: 「」, 
    「rtserver - id」: 1, 
    lon: 34.847, 
    lat: 32.123, 
    venue: 「」, 
    venue_context: 「」, 
    source: 「」, 
    locale: 「」 
} 
W.setOffer(aAdData, aClientEnv);

問題是行連接。

這

String script = 
      "var aLocation = {}" + 
        "var aOffer = {}" + 
        "var aAdData = " + 
        "{ " + 
        "location: aLocation, " + 
        "offer: aOffer " + 
        " } " 

是一樣的：

String script = 
      "var aLocation = {}var aOffer = {}var aAdData = { location: aLocation, offer: aOffer } " 

這是無效的jsavascript。你可以使用新行或;之間每個變種
