- 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".
复制代码 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}
复制代码 问下为什么输出的不是projSysID_9的值??? |
