如何使用Selenium ExecuteScript函數獲取HashTable

Question

使用Selenium WebDriver，一次為C＃中的標簽獲取所有html屬性，我這樣做

ReadOnlyCollection<object> HtmlAttributes = (ReadOnlyCollection<object>)((IJavaScriptExecutor)Driver).ExecuteScript("var s = []; var attrs = arguments[0].attributes; for (var l = 0; l < attrs.length; ++l) { var a = attrs[l]; s.push(a.name + ':' + a.value); } ; return s;", ele);

但是有了這段JavaScript代碼，我得到了一個帶有值的數組：

HtmlAttributes[index] = "HtmlAttribute:Value".

是否可以獲取哈希表？ 例如：

HtmlAttributes[HtmlAttribute] = "Value"

Answer 1

為什么下面的工作不起作用？

// Putting this all on one line would work just fine; I'm
// breaking it out here for readability.
string script = 
    @"var s = {};
      var attrs = arguments[0].attributes;
      for (var index = 0; index < attrs.length; ++index) {
        var a = attrs[index];
        s[a.name] = a.value;
      }
      return s;";

// Direct casting would work in a single line as well.
// Again, using the "as" operator and multiple lines for
// readability.
// ASSUMPTIONS: "driver" is a valid IWebDriver object, and
// "element" is a valid IWebElement object found using FindElement.
IJavaScriptExecutor executor = driver as IJavaScriptExecutor;
Dictionary<string, object> attributes = executor.ExecuteScript(script, element) as Dictionary<string, object>;

現在，對此有兩個警告。 首先是ExecuteScript序列化程序不能很好地遞歸過於復雜的對象。 這意味着，如果屬性具有對象作為其值，則可能無法達到您想要的效果。 例如，我不會嘗試從JavaScript序列化jQuery對象。 另一個警告是，返回類型將為Dictionary<string, object> 。 如果要創建Hashtable或將值轉換為字符串，則必須在從JavaScript中獲取值后自行轉換這些值。
