几个判断，并强制设置焦点：
//+------------------------------------
// trim 去除字符串两端的空格
String.prototype.trim=function(){return this.replace(/(^\s*)|(\s*$)/g,"")}
//-------------------------------------
// avoidDeadLock 避免设置焦点死循环问题
// 起死原因：以文本框为例，当一个文本框的输入不符合条件时，这时，鼠标点击另一个文本框，触发第一个文本框的离开事件
// ，产生设置焦点动作。现在产生了第二个文本框的离开事件，因此也要设置第二个文本框的焦点，造成死锁。
// 解决方案：设置一个全局对象[key]，记录当前触发事件的对象，若其符合条件，则释放该key；若其仍不符合，则key还是指
// 向该对象，别的对象触发不到设置焦点的语句。
