标题: lr_paramarr_idx使用的求助

1. Example: lr_paramarr_idx and lr_paramarr_len
   
2. 
   
3. This example shows how to get the last value from a parameter array.
   
4. 
   
5. int arrSize;
   
6. 
   
7. char * FlightVal;
   
8. 
   
9. web_reg_save_param("outFlightVal",
   
10. 
    
11.     "LB=outboundFlight value=", "RB=>",
    
12. 
    
13.     "ORD=ALL",
    
14. 
    
15.     "SaveLen=18",
    
16. 
    
17.     LAST );
    
18. 
    
19. web_submit_form("reservations.pl",
    
20. 
    
21.     "Snapshot=t4.inf",
    
22. 
    
23.     ITEMDATA,
    
24. 
    
25.     "Name=depart", "Value=London", ENDITEM,
    
26. 
    
27.     "Name=departDate", "Value=11/20/2003", ENDITEM,
    
28. 
    
29.     "Name=arrive", "Value=New York", ENDITEM,
    
30. 
    
31.     "Name=returnDate", "Value=11/21/2003", ENDITEM,
    
32. 
    
33.     "Name=numPassengers", "Value=1", ENDITEM,
    
34. 
    
35.     "Name=roundtrip", "Value=<OFF>", ENDITEM,
    
36. 
    
37.     "Name=seatPref", "Value=None", ENDITEM,
    
38. 
    
39.     "Name=seatType", "Value=Coach", ENDITEM,
    
40. 
    
41.     "Name=findFlights.x", "Value=83", ENDITEM,
    
42. 
    
43.     "Name=findFlights.y", "Value=16", ENDITEM,
    
44. 
    
45.     LAST );
    
46. 
    
47. /*
    
48. 
    
49. The result of the web_reg_save_param having been called before the web_submit_form is:
    
50. 
    
51. Notify: Saving Parameter "outFlightVal_1 = 230;378;11/20/2003"
    
52. 
    
53. Notify: Saving Parameter "outFlightVal_2 = 231;337;11/20/2003"
    
54. 
    
55. Notify: Saving Parameter "outFlightVal_3 = 232;357;11/20/2003"
    
56. 
    
57. Notify: Saving Parameter "outFlightVal_4 = 233;309;11/20/2003"
    
58. 
    
59. Notify: Saving Parameter "outFlightVal_count = 4"
    
60. 
    
61. */
    
62. 
    
63. arrSize = lr_paramarr_len("outFlightVal");
    
64. 
    
65. FlightVal = lr_paramarr_idx("outFlightVal", arrSize);
    
66. 
    
67. // 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

1. srand(time(NULL));
   
2.         i = rand()%20;
   
3.         i = i+1;
   
4.         lr_save_string(lr_paramarr_idx("projSysID",i),"p_projSysID");
   
5.         lr_output_message("p_projSysID=%s",lr_eval_string("{p_projSysID}"));
   
6. //最后的输出如下：
   
7. 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？？？
