One: Bring up the system with enter key keyboardIn the project there are often input boxes, when the input is completed click OK to perform the corresponding action. However, some of the design is not determined or search button, this need to call the system keyboard, click on the system keyboard to perform the corresponding action.But the simple input is not possible, to call the

Suppose we update the code at this point and submit the latest compilation results to the remote server for the client to download.Notice I modified the home.html:The next process is, don't go wrong:(1) Execute ionic build--prod to compile our modified code to generate the l
character. For example, the default ASCII string corresponding to the F5 key is "5~".Use the Xmodmap tool to modify the correspondence between keyboard and key symbol names. For example, the key code for "A" in X window is 30, while the key code for "Q" is 16. If you set up file Maptest:= QRunning in Xterm$ xmodmap MaptestAfter that, you will find that the "A" key and the "Q" key have been exchanged.The Maptest file above is actually a simple X Windo
