配置多个数据源datasource

方式1 ：checkbox

先看效果

源码如下：

<!DOCTYPE html>

<html>

<head>

<meta charset="utf-8">

<script src="https://cdn.staticfile.org/jquery/1.10.2/jquery.min.js">

</script>

<script>

function getSelected(){

    let arr = [];

    $("input[id^='check']:checked").each(function () {

         arr.push($(this).val());

    });

    document.getElementById("demo").innerHTML='你选中了：'+arr.join(',');

}

</script>

</head>

<body>

<form>

<input type="checkbox" id="check1" value='1'>level 1

<input type="checkbox" id="check2" value='2'>level 2

<input type="checkbox" id="check3" value='3'>level 3

<input type="checkbox" id="check4" value='4'>level 4

</form>

<br/><br/>

<button onclick="getSelected()">统计选中</button>

<p id="demo"></p>

</body>

</html>

方式2 ：button

先看效果，颜值更高

源码如下：

<!DOCTYPE html>

<html>

<head>

<meta charset="utf-8">

<script src="https://cdn.staticfile.org/jquery/1.10.2/jquery.min.js">

</script>

<script>

$(document).ready(function(){

    $('button').click(function(){

        //每次点击的时候，切换当前的元素样式

         $(this).toggleClass('active');

    });

});

function myFunction(){

    var levelArr=[];

    $('button.level.active').each(function () {

        levelArr.push($(this).val());

    });

    $("#demo").text('选中了：'+levelArr.join(','));

}

</script>

<style type="text/css">

/* 样式默认为绿色 */

button.level {

outline: none;

border: 1px solid #00850B;

border-radius: 4px;

background: #FFFFFF;

font-family: PingFangSC-Medium;

font-size: 14px;

color: #00850B;

text-align: center;

line-height: 18px;

}

/* 选中后样式 */

button.green.active{

   color: #FFFFFF;

   background:#00850B;

}

/* 覆盖默认样式 */

button.blue {

border: 1px solid #1273C7;

background: #FFFFFF;

color: #1273C7;

}

button.blue.active{

   color: #FFFFFF;

   background:#1273C7;

}

button.yellow {

border: 1px solid #E3AD2F;

background: #FFFFFF;

color: #E3AD2F;

button.yellow.active{

   color: #FFFFFF;

   background:#E3AD2F;

}

button.red {

border: 1px solid #D60505;

background: #FFFFFF;

color: #D60505;

}

button.red.active{

   color: #FFFFFF;

   background:#D60505;

}

</style>

</head>

<body>

<button class="level green" value='1'>level 1</button>

<button class="level blue" value='2'>level 2</button>

<button class="level yellow" value='3'>level 3</button>

<button class="level red" value='4'>level 4</button>
