Using JS, you can use the Enter key and ctrl key to navigate in the text box.

Users of the current development project are used to entering data with a keypad, such as entering 1, replacing it with "++", inputting 2, and replacing it with "AAA,

And use enter to wrap the line. In order to meet these user needs, I specially wrote two sections of JSCode, The first one is relatively simple, so it will not be pasted. The second function is pasted as follows:

 

 

Press enter to wrap up, press Ctrl + press enter to wrap up
// /
// /Usage
// /Window. onload = loadenternav;
// /PS:
// /1. You can set whether to jump out of the input enter navigation in function keydown.
// /2. In function loadenternav, you can set the style and event to be executed after the text box obtains the focus.

/* ========== Some variables ================ */
VaR Isctrl =   False ; // Mark whether to press Ctrl
VaR Currinput; // Current input
VaR Arrinput =   New Array (); // Page text box Array

// End

FunctionKeydown (e ){
VaREVT=E|Window. event;

Switch(EVT. keycode ){
Case 17://CTRL
Isctrl= True;
Break;

Case   13 : // Enter
If (Isctrl ){
// Go to the previous line
Gotolastinput ( True );
}
Else {
// Jump to the next line

// EVT. keycode = 9 can jump out of the text input navigation and enter the original navigation page

Gotolastinput ( False ); // Only in text input navigation
}
Break ;
Default : Break ;
}

}

FunctionKeyup (e ){
VaREVT=E|Window. event;

If(EVT. keycode= 17){
Isctrl= False;
}

}

FunctionKeypress (e ){
VaREVT=E|Window. event;

If(EVT. keycode= 17){
Isctrl= True;
}

}

/*====== Jump up input ===== start ======*/

FunctionSetobj (input ){
Currinput=Input;
}

//Go to the previous line
FunctionGotolastinput (islast ){

If (currinput ! = null ) {

for ( var I = 0 , lth = arrinput. length; I lth; I + ) {
If (currinput = arrinput [I]) {

If (Islast ){ // Jump up

If (I ! =   0 ){

Arrinput [I -   1 ]. Focus ();

}
Else {

Arrinput [lth -   1 ]. Focus ();
}
}
Else { // Jump down

If (I < Lth - 1 ){

Arrinput [I +   1 ]. Focus ();
}

}
Break ;
}
}
}
}

//Jump up to input ******* end */

// // Add the enter line feed event to the text box
Function Loadenternav (){

VaR T = Document. getelementsbytagname ( " Input " )
For (I =   0 ; I < T. length; I ++ )
If (T [I]. Type =   " Text " ){

T [I]. onfocus = New function ( " setobj (this); this. style. backgroundcolor = '# cccccc'; this. select (); " )
T [I]. onblur = New function ( " This. style. backgroundcolor = '' " )

T [I]. onkeydown=Keydown;
T [I]. onkeyup=Keyup;
T [I]. onkeypress=Keypress;

//Save page text box
Arrinput. Push (T [I]);

}
}
