lr_paramarr_idx使用的求助

Example: lr_paramarr_idx and lr_paramarr_len

This example shows how to get the last value from a parameter array.

int arrSize;

char * FlightVal;

web_reg_save_param("outFlightVal",

    "LB=outboundFlight value=", "RB=>",

    "ORD=ALL",

    "SaveLen=18",

    LAST );

web_submit_form("reservations.pl",

    "Snapshot=t4.inf",

    ITEMDATA,

    "Name=depart", "Value=London", ENDITEM,

    "Name=departDate", "Value=11/20/2003", ENDITEM,

    "Name=arrive", "Value=New York", ENDITEM,

    "Name=returnDate", "Value=11/21/2003", ENDITEM,

    "Name=numPassengers", "Value=1", ENDITEM,

    "Name=roundtrip", "Value=<OFF>", ENDITEM,

    "Name=seatPref", "Value=None", ENDITEM,

    "Name=seatType", "Value=Coach", ENDITEM,

    "Name=findFlights.x", "Value=83", ENDITEM,

    "Name=findFlights.y", "Value=16", ENDITEM,

    LAST );

/*

The result of the web_reg_save_param having been called before the web_submit_form is:

Notify: Saving Parameter "outFlightVal_1 = 230;378;11/20/2003"

Notify: Saving Parameter "outFlightVal_2 = 231;337;11/20/2003"

Notify: Saving Parameter "outFlightVal_3 = 232;357;11/20/2003"

Notify: Saving Parameter "outFlightVal_4 = 233;309;11/20/2003"

Notify: Saving Parameter "outFlightVal_count = 4"

*/

arrSize = lr_paramarr_len("outFlightVal");

FlightVal = lr_paramarr_idx("outFlightVal", arrSize);

// FlightVal contains the value "233;309;11/20/2003". 以上是官方帮助文档里的,以下是我自己的srand(time(NULL));
      i = rand()%20;
      i = i+1;
      lr_save_string(lr_paramarr_idx("projSysID",i),"p_projSysID");
      lr_output_message("p_projSysID=%s",lr_eval_string("{p_projSysID}"));
//最后的输出如下:
Action.c(145): p_projSysID={projSysID_5}问下为什么输出的不是projSysID_9的值???
