切换功能更新的事件如下:

js:

navbarActiveSwitch();
var isclick=false;
$(function () {
$("label").on({
mouseover:function(){
$(this).addClass('clicks');
$(this).removeClass('point_amount_label');
$(this).siblings('label').removeClass('clicks');
$(this).siblings('label').addClass('point_amount_label');
},
mouseout:function(){
if(!isclick){
console.log(1);
$(this).addClass('point_amount_label');
$(this).removeClass('clicks');
}
},
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>');
}
});

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

});

 

 

})

 

 

 

html:

<label id="credit_amount_20" class=" click " amount="20">¥20.00<div class="arrow-down"></div></label>
<label id="credit_amount_50" class="point_amount_label " amount="50">¥50.00</label>
<label id="credit_amount_100" class="point_amount_label " amount="100">¥100.00</label>
<label id="credit_amount_0" class="point_amount_label " >其他金额</label>
