cocos3——5.js获取文件夹下文件列表

概述1.C++： #include <iostream>#include <fstream>#include <vector>#include <string>#include "cocos2d.h"#if CC_TARGET_PLATFORM == CC_PLATFORM_WIN32#include <windows.h>#include <strsafe.h>#else#i

1.C++：

#include <iostream>#include <fstream>#include <vector>#include <string>#include "cocos2d.h"#if CC_TARGET_PLATFORM == CC_PLATFORM_WIN32#include <windows.h>#include <strsafe.h>#else#include <dirent.h>#endifnamespace fs {	int readDir( const char *path,vector<string> &names )	{		names.clear();#if CC_TARGET_PLATFORM == CC_PLATFORM_WIN32		WIN32_FIND_DATAA ffd;		//LARGE_INTEGER filesize;		string szDir;		//size_t length_of_arg;		HANDLE hFind = INVALID_HANDLE_VALUE;		DWORD DWError=0;		string strDir = path;		szDir = strDir + "\*";		hFind = FindFirstfileA(szDir.c_str(),&ffd);		if (INVALID_HANDLE_VALUE == hFind) 		{			//cclOGWARN("get file name error",path);			return 0;		}		do		{			if (!(ffd.DWfileAttributes & file_ATTRIBUTE_DIRECTORY))			{				string filename=ffd.cfilename;//(const char*)				//string filedir=strDir+"\"+filename;				string filedir = filename;				names.push_back(filedir);			}		}while (FindNextfileA(hFind,&ffd) != 0);		DWError = GetLastError();		if (DWError != ERROR_NO_MORE_fileS) 		{			//cclOGWARN("FindFirstfile error",path);			return 0;		}		FindClose(hFind);#else		DIR *dp = opendir(path);		if (!dp) {			//cclOGWARN("open dir error: %s.",path);			return 0;		}		struct dirent *dirp = readdir(dp);		while (dirp) {			if (!strcmp(dirp->d_name,".") || !strcmp(dirp->d_name,".."))				continue;			names.push_back(dirp->d_name);		}		closedir(dp);		sort(names.begin(),names.end());#endif		return names.size();	}}

2.绑定Js：

bool Js_fs_readDir(jscontext *cx,uint32_t argc,Jsval *vp){	if (argc == 1) {		// get the native object from the second object to the first object		Jsval *argv = Js_ARGV(cx,vp);		string path;		Jsval_to_std_string(cx,argv[0],&path);		vector<string> names;		fs::readDir(path.c_str(),names);		Jsval Jsret = JsVAL_NulL;		Jsret = std_vector_string_to_Jsval(cx,names);		Js_SET_RVAL(cx,vp,Jsret);		return true;	}	return false;}

3.Js调用：

var files = fs.readdir(full_path);

PS: 这里要传全路径，貌似androID要把文件拷到可写路径去才能获取到文件列表。。 总结
