if 判断有问题, 如何解释?

小李美刀

这是WR自带的FLIGHT 例子, 我录制了脚本, 但在报告里显示的是"The Flights button was successfully enabled", 实际上 Insert Order 按钮是灰色的,处于不可用状态, 所以 if(value=0) 的判断结果应该是真, 这样else就不应该执行才对, 请问怎么解释呢?

set_window ("Flight Reservation");
obj_type("MSMaskWndClass","120106");

#Type in a value in the Fly From: box
list_select_item ("Fly From:", "Portland");
#Type in a value in the Fly To: box
list_select_item ("Fly To:", "Denver");
#Check that the Flights button is enabled

button_get_state ("Insert Order", value);

if (value = 0)
report_msg ("Flights button was not enabled. Check that values for Fly From and Fly To are valid");

else

report_msg ("The Flights button was successfully enabled");

1： Insert Order 按钮是灰色的
2：那么value的状态值应该是非真
3：非真即假，假即非零
4：所以i应该走else分支

小李美刀

楼上的姐姐, 我设的 value = 0, 即灰色的按钮状态应该是真,  所以应该走第一条语句才对吧

是不是判断语句不对呀？ if (value = 0)
试一下 if (value == 0)

小李美刀

可以写成:  value==0 吗 ???

那怎么解释呢,  好想偶有点晕

快乐逍遥

楼上的兄弟，判断中的等于是使用恒等号"==" 的呀

生如火花

=是赋值，==是条件

小李美刀

各位哥哥姐姐，还是不正确，下面的code中，Insert Order 按扭是可用状态的，但执行的仍是　If 　语句的第一个分支，那判断还是错误的呀，该怎么解释吗？
set_window ("Flight Reservation");
obj_type("MSMaskWndClass","120106");

#Type in a value in the Fly From: box
list_select_item ("Fly From:", "Portland");
#Type in a value in the Fly To: box
list_select_item ("Fly To:", "Denver");
#Check that the Flights button is enabled
obj_mouse_click ("FLIGHT", 38, 30, LEFT);
set_window("Flights Table");
list_select_item("Flight","#3");
button_press("OK");
set_window("Flight Reservation");
obj_type("Name:","lihai");
wait(2);

button_get_state ("Insert Order", value);
if (value == 0)
{
report_msg ("Flights button was not enabled. Check that values for Fly From and Fly To are valid");
button_press("Insert Order");
}
else

report_msg ("The Flights button was successfully enabled");

0是E_OK,也就是真，如果按钮是灰的，那就执行else

小李美刀

斑竹，但现在下面的程序中按扭是灰色的，但却没有执行 else　语句，它执行的是第一条语句：report_msg ("The Flights button was successfully enabled");　我还是不明白．

set_window ("Flight Reservation");
obj_type("MSMaskWndClass","120106");

#Type in a value in the Fly From: box
list_select_item ("Fly From:", "Portland");
#Type in a value in the Fly To: box
list_select_item ("Fly To:", "Denver");
#Check that the Flights button is enabled

button_get_state ("Insert Order", value);

if (value ==E_OK)
report_msg ("The Flights button was successfully enabled");

else

report_msg ("Flights button was not enabled. Check that values for Fly From and Fly To are valid");
