To configure parameters for the PPAPI plug-in in HTML

In HTML, you can configure the plug-in by embed or the object tag. Using embed is similar to the following:

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

Using object is similar to the following:

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

When the Ppapi plugin is instantiated, you can receive the parameters configured in embed or object. All attributes that are embedded in the tag (such as id= "Myplugin"), param specified parameters, are passed to the Ppp_instance method in the form of a name-value pair. The method is prototyped as follows:

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

Where ARGC is the number of arguments in a CEF-collected embed or object, argn array is the parameter name, and the argv array is the value of the parameter. The parameters can be handled in code like this:

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 < argc; i++)    {        sprintf_s(szLog, 256, "name=%s, value=%s\r\n", argn[i], argv[i]);        OutputDebugStringA(szLog);    }    ...}

For the previous example of the object tag, using DebugView you might see the following output:

Ok, the parameters can be processed, the plugin can be customized.
