Getting the error in Script "Uncaught SyntaxError: Unexpected token )"

Question

在方法 EvaluateScriptAsync（脚本）中使用 CefSharp 时剧本如下

 script = @"(function(){var linksArray = new Array();
        for (var i = 0; i < document.querySelectorAll('.g').length; i++)
            {
var elementWithClassRC = document.querySelectorAll('.g')[i].querySelectorAll('.rc');
 var rElement = elementWithClassRC[0].getElementsByClassName('r');
 var sElement= elementWithClassRC[0].getElementsByClassName('s');
 var hrefValue = rElement[0].querySelector('a').getAttribute('href');
 var h3Value = rElement[0].querySelector('a').querySelector('h3').innerHTML;
 var spanValue = sElement[0].querySelector('span').innerText;
 linksArray[i] = [hrefValue,h3Value,spanValue];
 return linksArray;})();";

在评估结果中，我得到 javaScriptResponse.Result 作为此错误“"Uncaught SyntaxError: Unexpected token )\n@ about:blank:13:22"”。请帮我解决这个问题。

您在 for 循环中缺少“}”。

script = @"(
       function(){
          var linksArray = new Array();
          for (var i = 0; i < document.querySelectorAll('.g').length; i++) {
             var elementWithClassRC = document.querySelectorAll('.g')[i].querySelectorAll('.rc');
             var rElement = elementWithClassRC[0].getElementsByClassName('r');
             var sElement= elementWithClassRC[0].getElementsByClassName('s');
             var hrefValue = rElement[0].querySelector('a').getAttribute('href');
             var h3Value = rElement[0].querySelector('a').querySelector('h3').innerHTML;
             var spanValue = sElement[0].querySelector('span').innerText;
             linksArray[i] = [hrefValue,h3Value,spanValue];
          // for loop is not end here
          return linksArray;
  })();";
