 3     Transform gridTran = this.characterGrid.transform;
 4     InputField childInputField;
 5     // 这里遍历 Grid Layout Group 中的所有子节点
 6     for(int i=0; i<gridTran.childCount-1; ++i)
 7     {
 8         childInputField = gridTran.GetChild(i).GetComponent<InputField>();
 9         if (childInputField.isFocused)
