number keypad practice

The project in Vue, based on Vux-ui development, is a common requirement:1, the amount of input box 2, pop-up number keypad 3, only support input two decimal places, limit the maximum 11 digits, do not allow 0 startFirst, the first thought is the vux-ui in the development of Type=number. --Not OKVux in the document and code description, Type=

Reason Analysis: This problem is due to the fact that the WIN10 has been turned on with its own mouse button function. Solution: Open "Start"-"Settings"-"easy to use"-"mouse"; In the inside close "use the numeric keypad to move the mouse on the screen" after the problem solved. Some instructions for this feature: If the "use of the digital keypad on the screen to move the mou

Careful netizen in the process of using WIN8 system, will find a problem, we to WIN8 system computer boot, the keyboard in the digital area by default is closed, we need to press NUM LOCK to open it, can use the numeric keypad, so that the recognition will affect the user's operation, So the Hedong Software Park small make up for everyone to solve the method, can let us after each boot without pressing NUM LOCK to open the numeric

, the same problem occurs when the value of v.size () is greater than or equal to 2*1024*1024*1024.To avoid this problem, we can use the Size_tupe or iterator provided by the vector:For (VectorSize_tupe is guaranteed to be unsigned, so the first form (using unsigned numbers) is more than the version of the INT-type loop variable, with a bits that represents the value of the loop variable (not the symbol). This improvement is important, but after all it is just one more to indicate the scope of t

Self-initiated test script writing, test data preparation, and so on.An objective entry criterion with operational and monitoring access.Although the entrance guidelines are for testing activities, they should not be conducted solely by the Test team, but should be discussed in a broader context.
