在HTML中,可以通过embed或object标签来配置插件。使用embed类似下面这样:

<embed id="myplugin" type="application/x-ppapi-myplugin" width="1200px" height="520px"></embed>
Copy after login

使用object类似下面这样:

<object id="myplugin" type="application/x-ppapi-myplugin" width="1200px" height="520px" custom="i am custom">  <param name="tang" value="desktop"></object>
Copy after login

PPAPI插件实例化时,可以收到在embed或object中配置的参数。所有嵌在标签中的属性(比如id=”myplugin”)、param指定的参数,都会以name-value对的形式传递给PPP_Instance接口的DidCreate方法。该方法原型如下:

PP_Bool (*DidCreate)(PP_Instance instance,                     uint32_t argc,                     const char* argn[],                     const char* argv[]);
Copy after login

其中,argc是CEF搜集的embed或object中的参数个数,argn数组是参数名字,argv数组是参数的值。代码中可以这样处理参数:

PP_Bool Instance_DidCreate(PP_Instance instance,    uint32_t argc,    const char* argn[],    const char* argv[]) {    ...    char szLog[256] = { 0 };    sprintf_s(szLog, 256, "PPAPI Got %d params\r\n", argc);    OutputDebugStringA(szLog);    for (int i = 0; i     <p>针对前面的object标签示例,使用DebugView可能看到下面的输出:</p>    <p></p>    <p>Ok,能处理参数,插件就可以定制化了。</p>    <p>其他参考文章:</p>
