Enter键替代Tab键切换焦点(Ext)

Enter键替代Tab键切换焦点(Ext)

一、el
var el = Ext.get('例如：formname');
var map = new Ext.KeyMap(el, {
key: Ext.EventObject. ENTER,
fn: function(){
event.keyCode=9;
}
});

二、EditGrid，需修改源码
onEditorKey:function (F, E) {
 var C = E.getKey(), G, D = this.grid, B = D.activeEditor;
 var A = E.shiftKey;
 if (C == E.TAB) {
  E.stopEvent();
  B.completeEdit();
  if (A) {
   G = D.walkCells(B.row, B.col - 1, -1, this.acceptsNav, this);
  } else {
   G = D.walkCells(B.row, B.col + 1, 1, this.acceptsNav, this);
  }
 } else {
  if (C == E.ENTER) {
   E.stopEvent();
   B.completeEdit();
   if (this.moveEditorOnEnter !== false) {
    if (A) {
     //G  =  D.walkCells(B.row  -   1 , B.col,  - 1 ,  this .acceptsNav, this )
     G = D.walkCells(B.row, B.col - 1, -1, this.acceptsNav, this);
    } else {
     // G  =  D.walkCells(B.row  +   1 , B.col,  1 ,  this .acceptsNav, this )
     G = D.walkCells(B.row, B.col + 1, 1, this.acceptsNav, this);
    }
   }
  } else {
   if (C == E.ESC) {
    B.cancelEdit();
   }
  }
 }
 if (G) {
  D.startEditing(G[0], G[1]);
 }
}
