cellpadding="0" cellspacing="0">

class="input_out" type="text"

οnfοcus="this.className='input_on';this.οnmοuseοut=''"

οnblur="this.className='input_off';this.οnmοuseοut=function(){this.className='input_out'};"

οnmοusemοve="this.className='input_move'"

οnmοuseοut="this.className='input_out'"

/>

class="input_out" type="text"

οnfοcus="this.className='input_on';this.οnmοuseοut=''"

οnblur="this.className='input_off';this.οnmοuseοut=function(){this.className='input_out'};"

οnmοusemοve="this.className='input_move'"

οnmοuseοut="this.className='input_out'"

/>

class="input_out" type="text"

οnfοcus="this.className='input_on';this.οnmοuseοut=''"

οnblur="this.className='input_off';this.οnmοuseοut=function(){this.className='input_out'};"

οnmοusemοve="this.className='input_move'"

οnmοuseοut="this.className='input_out'"

/>

执行结果：

另一种方法：(点击之后边框变为红色，鼠标滑过没有效果)：

function ofocus(Obj){

Obj.style.border='solid 2px red';

}

function oblur(Obj){

Obj.style.border='solid 1px #999';

}

οnfοcus="ofocus(this)" οnblur="oblur(this)" />

οnfοcus="ofocus(this)" οnblur="oblur(this)" />

οnfοcus="ofocus(this)" οnblur="oblur(this)" />

执行结果：
