    html:

    <label id="credit_amount_20" class=" click have" amount="20">¥20.00<div class="arrow-down"></div></label>
    <label id="credit_amount_50" class="point_amount_label have" amount="50">¥50.00</label>
    <label id="credit_amount_100" class="point_amount_label have" amount="100">¥100.00</label>
    <label id="credit_amount_0" class="point_amount_label none" >其他金额</label>

    js:

    $("label").on({
    mouseover:function(){
    $(this).addClass('click');
    $(this).removeClass('point_amount_label');
    $(this).append('<div class="arrow-down"></div>');
    $(this).siblings('label').removeClass('click');
    $(this).siblings('label').addClass('point_amount_label');
    $(this).siblings('label').children().remove();
    },
    mouseout:function(){
    if(!isclick){
    $(this).addClass('point_amount_label');
    $(this).removeClass('click');
    $(this).children().remove();
    }
    },
    click:function(){
    $(".amount_input ").val('').focus();
    $('.red-text').text($(this).attr('amount'));
    $(this).siblings('label').removeClass('click');
    $(this).siblings('label').addClass('point_amount_label');
    $(this).siblings('label').children().remove();
    $(this).addClass('click');
    $(this).removeClass('point_amount_label');
    $(this).append('<div class="arrow-down"></div>');
    isclick=true;
    }
    });

    光标事件:

    $('.amount_input').blur(function(){
    var val=$('.amount_input').val();
    $('.red-text').text(val);

    });
