前兩天做項(xiàng)目需要動態(tài)添加echarts桨菜，可把我難住了禀崖，問了好多人終于解決徒扶，今天分享一下
html
<!-- 點(diǎn)擊的按鈕 -->
<div class="btn">點(diǎn)擊</div>
<!-- 需要添加echarts的盒子 -->
<div class="cont"></div>
css
.cont{
width: 500px;
height: 500px;
border: 1px solid blue;
}
.box{
width: 200px;
height: 200px;
border: 1px solid red;
margin: 10px 0;
}
echarts.js
function echar(){
var arr = Array.from(document.querySelectorAll(".c1"));
var charArr = arr.map(item=>echarts.init(item))
// 配置數(shù)據(jù)
var option1 = {
title: {
text: 'ECharts 入門示例'
},
tooltip: {},
xAxis: {
data: ["襯衫","羊毛衫","雪紡衫","褲子","高跟鞋","襪子"]
},
yAxis: {},
series: [{
name: '銷量',
type: 'bar',
data: [5, 20, 36, 10, 10, 20]
}]
};
// 渲染圖表
charArr.forEach(item=>item.setOption(option1))
}
點(diǎn)擊插入的js
$(function(){
$('.btn').click(function(){
$('.cont').append('<div class="box"></div>')
var c1 = $('.box').children('.c1');
console.log(c1.length);
if(c1.length == 0){
$('.box').append('<div class="c1" style="width:100%;height:100%;"></div>')
}else if(c1.length>0){
$('.box').append('<div class="c1" style="width:100%;height:100%;"></div>')
for(var i=0;i<c1.length;i++){
$('.box .c1:eq('+i+')').remove();
}
}
echar();
})
})
