生成下拉选项的json

    TTable userTable = DBMgr::getdb()->query("SELECT K AS Names FROM S_CFG");
    vector<string> vec;
    for(int i=0;i<userTable.size();i++) {
        string stmp = userTable.getValue(i,"Names");
        vec.push_back("{\"id\":\""+stmp+"\",\"name\":\""+stmp+"\"}");
    }
    string json = "[" + StringUtil::join(vec, ",") + "]";
    wMDropdown1->setOptions(json, 0);

上面是字符串相加生成json

============多语言===========

下面是用json工具

#define LOCALE_STR(tag) getRuntime()->getILanguageMgr()->getTag(string("_L(\"")+tag+string("\")"))

void Frm09::onLoad() {

vector<vector<KV_Str_Str>> vec1;

vector<KV_Str_Str> vec;

 

// 选项1的id

KV_Str_Str kv1;

kv1.k = "id";//固定为id

kv1.v = "0";//选项1的value

vec.push_back(kv1);

// 选项1的name

KV_Str_Str kv2;

kv2.k = "name";//固定为name

kv2.v = LOCALE_STR("多语言标签1");//选项的名称(显示的文字)

vec.push_back(kv2);

// 选项1加入数组

vec1.push_back(vec);

 

//继续选项2......

 

//生成json

string json1 = "";

Util::convertArrayToJson(vec1, json1);

//设置给控件

wMDropdown2->setOptions(json1, 0);

}
