Cocos3 -- 5. js get the file list in the folder
1. C ++:
#include
#include
#include
#include
#include "cocos2d.h"#if CC_TARGET_PLATFORM == CC_PLATFORM_WIN32#include
#include
#else#include
#endifnamespace fs {int readDir( const char *path, vector
&names ){names.clear();#if CC_TARGET_PLATFORM == CC_PLATFORM_WIN32WIN32_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);#elseDIR *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());#endifreturn names.size();}}
2. Bind 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 objectjsval *argv = JS_ARGV(cx, vp);string path;jsval_to_std_string(cx, argv[0], &path);vector
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 call:
var files = fs.readdir(full_path);
PS: the full path is required. It seems that android will copy the file to the Writable Path to obtain the file list ..
