The following code in the

Var $inp=$(' input: text ');//get all the input box (including an editor)
$inp. Bind (keydown, function (e) {
Var key= e.w hich;
If (key==13) {//13 to enter

E.p reventDefault ();//cancel the enter default state
Var nxtIdx=$inp. Index (this) + 1;
Var readonly=$(" : input: text: eq (" + nxtIdx + ") "). The prop (" readonly ");//get the next focus of state
While (readonly) {//the moment a focus for an editor state skip change focus
NxtIdx=nxtIdx + 1;
Readonly=$(" : the input text: eq (" + nxtIdx + ") "). The prop (" readonly ");
if(! Readonly) {
break;
}
}
$(" : the input text: eq (" + nxtIdx + ") "). The focus ();//get focus

}

Excuse me:

1, var $inp=$(' input: text);//for all input in the input box: text what is this grammar, what kind of book is about
2, e.w hich is what? What materials have speak

The first is the CSS selector syntax
The second is the rid_device_info_keyboard event object a read-only property

See jq CSS selector https://www.w3school.com.cn/jquery/jquery_ref_selectors.asp
