会员等级进度功能前端实现

一、切图

1、效果

真实效果如下。

为说明问题只保留有用代码。进度条宽度用百分比来表示,这样适配时不需要重新计算。

2、切图代码

html代码如下:

<!DOCTYPE HTML>
<html>

<head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <title></title>

    <!--页面初始化CSS和页面公用头部的css-->
    <link rel="stylesheet" href="css/vipgrowth.css">
    <!--新增样式的css,名称可根据具体需求修改-->
    <script type="text/javascript" src="http://static9.pplive.cn/vip/201508/center/v_20150901140940/js/jquery-1.9.1.min.js"></script>
    <script>
window.onresize=function(){
    var winWidth = document.body.clientWidth;
    if(winWidth <=1230){
        body.className="grid-1010"; 
    }else  if (winWidth<= 1410){
        body.className="grid-1230"; 
    }else if (winWidth>1410){
        body.className="grid-1410"; 
    }else {
        alert("do not know!");
    }
}
</script>
</head>

<body id="body">
<script>//初始化状态显示样式判断,放在body后面
var winWidth = document.body.clientWidth;
 if(winWidth <=1230){
        body.className="grid-1010"; 
    }else  if (winWidth<= 1410){
        body.className="grid-1230"; 
    }else if (winWidth>1410){
        body.className="grid-1410"; 
    }else {
        alert("do not know!");
    }
</script>
    <div class="vg-body">

3、切图分析

html结构如下:

<!--会员基本信息 开始-->
        <div class="vg_info ">
            <div class="vg_rank">
                <ul class="vg_rankBox cf"> 
                    <li >
                        <p class="vg_rankpoint">0</p>
                        <a class="vip vip1 light "></a>
                    </li>
                    <li>
                        <p class="itembar"></p>
                    </li>

                    <li>
                        <p class="itembar">
                            <span class="middle" style="width:60px;">
                                <em class="vg_rank_flag"></em>
                            </span>
                        </p>
                    </li>
                    <li>
                    <p class="vg_rankpoint">1800</p>
                        <a class="vip vip3"></a>
                    </li>
                    <li>
                        <p class="itembar"></p>
                    </li>
                    <li>
                    <p class="vg_rankpoint">3600</p>
                        <a class="vip vip4"></a>
                    </li>
                    <li>
                        <p class="itembar"></p>
                    </li>
                    <li>
                    <p class="vg_rankpoint">6000</p>
                        <a class="vip vip5"></a>
                    </li>
                    <li></li>
                </ul>
            </div>
        </div>
        <!--会员基本信息 结束-->

3.1点亮等级

 <a class="vip vip1 light "></a>代表,3个class,vip1表示等级为v1,light表示点亮。所以如果要点亮某个等级加class light即可。

3.2设置两个等级之间进度条满格

如上图,只需要设置class为middle的span的宽度为100%即可。

3.3显示小红旗

设置对应的class为vg_rank_flag的em的display属性为block即可。因为小红旗默认不显示。

二、js交互部分

1、思路

第一步:

传入参数:viplevel代表vip等级。growthlevel代表成长值。

第二步:

根据viplevel点亮<=viplevel等级的皇冠。【function1】

第三步:

v1:0<=growthlevel<600

v2:600<=growthlevel<1800

v3:1800<=growthlevel<3600

v4:3600<=growthlevel<6000

v5:6000=grothlevel

  • 根据viplevel点亮对应进度条。即设置span宽度100%。【function2】
  • 根据growthlevel判断
    • 如果growth=6000,不做任何操作。
    • 否则判断
    • 抽象一下公式
    • 所以根据growthlevel,判断得出y和x值,传入公式,计算并设置span的百分比。【function4】最后点亮小红旗。【function3】

2、代码实现

function1:

function lightCrown(viplevel){
    $(".vip").removeClass("light");
    for(var i=1;i<=viplevel;i++){
        var temp="vip"+i;
        $("."+temp).addClass("light");
    }
}

 function2:

function lightProgressBar(viplevel){
    for(var j=0;j<viplevel-1;j++){
        $(".vg_rankBox").find(".middle").eq(j).css("width","100%");
    }
}

 function3:

function lightFlag(viplevel){
    $(".vg_rankBox").find(".vg_rank_flag").eq(viplevel-1).css("display","block");
}

function4:

function calWidth(growthlevel){
    var cur;
    if (growthlevel==6000)return;
    if(0<=growthlevel&growthlevel<600){
        y=600;
        x=0;
        cur=0;
    }else if(600<=growthlevel&growthlevel<1800){
        y=1800;
        x=600;
        cur=1;    
    }else if(1800<=growthlevel&growthlevel<3600){
        y=3600;
        x=1800;
        cur=2;    
    }else if(3600<=growthlevel&growthlevel<6000){
        y=6000;
        x=3600;
        cur=3;    
    }
    var width=1-(y-growthlevel)/(y-x);
    $(".vg_rankBox").find(".middle").eq(cur).css("width",width*100+"%");
}

 整理一下调用过程就是:

function viprank(viplevel,growthlevel){
    lightCrown(viplevel);
    lightProgressBar(viplevel);
    calWidth(growthlevel);
    lightFlag(viplevel);
}
viprank(2,1200);
