徒手写一个简单的步骤线
第一种:
template
<div class="per-mobile-step"
v-for="(item,index) in steps"
:key="item.value"
@click="changeStep(item,index)"
:class="[
'per-mobile-step-'+index,
item.value==currentcomponent?'active':'',
index < currentcomponentindex?'active':''
]">
<div class="title-dot">
<i :class="[
item.value==currentcomponent?'active':'',
index < currentcomponentindex?'actived':''
]"></i>
<div class="line"
:class="[
index < currentcomponentindex?'active':''
]"
v-if="index!==3"></div>
</div>
<div class="title-text"
:class="[
'title-text-'+index,
item.value==currentcomponent?'active':'',
index < currentcomponentindex?'active':''
]">{{item.label}}</div>
</div>
上面的
index < currentcomponentindex?'active':''
为了记录当前步骤前的已完成的步骤,actived为已完成,active为当前展示步骤
js
data(){
return{
currentcomponent:"ac1",
currentcomponentindex:0,
steps:[
{
label:"身份验证",
value:"ac1"
},
{
label:"手机号绑定",
value:"ac2"
},
{
label:"设置密码",
value:"ac3"
},
{
label:"完成",
value:"ac4"
},
]
}
},
scss
// mobile
.per-mobile-step{
flex: 3;
font-size: 0.8rem;
line-height: 2;
color: #e2e2e2;
&.per-mobile-step-3{
flex: 1;//最后一步没有线条,做了flex比例缩减
}
.title-dot{
display: flex;
align-items: center;
>i{

display: block;
border-radius: 50%;

}
.line{

height: 1px;

&.active{
background: #f39800;
}
}
}
// 为了文字居中,包裹层向右边移动20px
// 字居中用relative做了偏移,有更好的方法代码请甩给我~
.title-text{
position: relative;
margin-top: 5px;
&.active{
color: #edc462;
}
}
.title-text-0{
left: -20px;
}
.title-text-1{
left: -23px;
}
.title-text-2{
left: -20px;
}
.title-text-3{
left: -10px;
}
}
第二种:
template
<div class="per-step"
v-for="(item,index) in steps"
:key="item.value"
@click="changeStep(item,index)"
:class="[
index!==0?'before-trangle':'',
index!==3?'after-trangle':'',
'per-step-'+index,
item.value==currentcomponent?'active':'',
index < currentcomponentindex?'active':''
]">
<span>{{item.label}}</span>
</div>
