  - executeJavaScript
```
void executeJavaScript(java.lang.String code,
                       java.lang.String url,
                       int line)
```
    Execute a string of JavaScript code in this frame. The url parameter is the URL where the script in question can be found, if any. The renderer may request this URL to show the developer the source of the error. The line parameter is the base line number to use for error reporting.
    (在此框架中执行一串JavaScript代码。 url参数是可以找到相关脚本的URL（如果有）。渲染器可以请求此URL向开发人员显示错误的来源。 line参数是用于错误报告的基线编号)
    
    参数:
    
    code - The code to be executed.
    
    url - The URL where the script in question can be found.
    
    line - The base line number to use for error reporting.
  - getIdentifier
```
long getIdentifier()
```
    Returns the globally unique identifier for this frame or < 0 if the underlying frame does not yet exist.
    (返回此帧的全局唯一标识符，如果基础帧尚不存在，则返回<0)
    
    返回:
    
    The frame identifier
  - getName
```
java.lang.String getName()
```
    Returns the name for this frame. If the frame has an assigned name (for example, set via the iframe "name" attribute) then that value will be returned. Otherwise a unique name will be constructed based on the frame parent hierarchy. The main (top-level) frame will always have an empty name value.
    (返回此帧的名称。如果框架具有指定的名称（例如，通过iframe“name”属性设置），则将返回该值。否则，将基于帧父层次结构构造唯一名称。主（顶级）框架将始终具有空名称值)
    
    返回:
    
    The frame name
  - getParent
```
CefFrame getParent()
```
    Returns the parent of this frame or NULL if this is the main (top-level) frame.
    (返回此帧的父级，如果这是主（顶级）帧，则返回NULL)
    
    返回:
    
    The parent frame or NULL if this is the main frame
  - getURL
```
java.lang.String getURL()
```
    Emits the URL currently loaded in this frame.
    (发出当前在此框架中加载的URL)
    
    返回:
    
    the URL currently loaded in this frame.
  - isFocused
```
boolean isFocused()
```
    Returns true if this is the focused frame.
    (如果这是聚焦框，则返回true)
    
    返回:
    
    True if valid otherwise false.
  - isMain
```
boolean isMain()
```
    Returns true if this is the main (top-level) frame.
    (如果这是主（顶级）帧，则返回true)
    
    返回:
    
    True if this frame is top-level otherwise false.
  - isValid
```
boolean isValid()
```
    True if this object is currently attached to a valid frame.
    (如果此对象当前附加到有效帧，则为True)
    
    返回:
    
    True if valid otherwise false.
