方法详细资料

dispose

void dispose()

Removes the native reference from an unused object. (从未使用的对象中删除本机引用。)

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，以向开发人员显示错误的来源。 line参数是用于错误报告的基准行号。)

参数:

code - The code to be executed. (-要执行的代码。)

url - The URL where the script in question can be found. (-可以找到相关脚本的网址。)

line - The base line number to use for error reporting. (-用于错误报告的基准编号。)

getIdentifier

long getIdentifier()

Returns the globally unique identifier for this frame or < 0 if the underlying frame does not yet exist. (返回此框架的全局唯一标识符；如果基础框架尚不存在，则返回<0。)

返回:

The frame identifier (帧标识符)

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. (返回此框架的名称。如果框架具有分配的名称（例如，通过iframe的“名称”属性设置），则将返回该值。否则，将基于框架父级层次结构构造一个唯一的名称。主（顶层）框架将始终具有一个空的名称值。)

返回:

The frame name (框架名称)

getParent

CefFrame getParent()

Returns the parent of this frame or NULL if this is the main (top-level) frame. (返回此框架的父级；如果这是主要（顶级）框架，则返回NULL。)

返回:

The parent frame or NULL if this is the main frame (父框架或NULL（如果这是主框架）)

getURL

java.lang.String getURL()

Emits the URL currently loaded in this frame. (退出当前在此框架中加载的URL。)

返回:

the URL currently loaded in this frame. (当前在此框架中加载的URL。)

isFocused

boolean isFocused()

Returns true if this is the focused frame. (如果这是焦点框，则返回true。)

返回:

True if valid otherwise false. (如果有效，则为true，否则为false。)

isMain

boolean isMain()

Returns true if this is the main (top-level) frame. (如果这是主（顶层）框架，则返回true。)

返回:

True if this frame is top-level otherwise false. (如果此框架是顶级，则为True，否则为false。)

isValid

boolean isValid()

True if this object is currently attached to a valid frame. (如果此对象当前已附加到有效框架，则为true。)

返回:

True if valid otherwise false. (如果有效，则为true，否则为false。)
