Bootstrap标签页（Tab）插件切换echarts不显示问题的解决

本文主要是介绍Bootstrap标签页（Tab）插件切换echarts不显示问题的解决，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

问题：

1.  在echarts跟bootstrap选项卡整合的时候，默认第一个选中选项卡可以正常加载echarts图表，但是切换其他选项的时候不能渲染出其他选项卡echarts图表。

2.  echarts自适应怎么实现？

解决办法：

//解决tab切换不显示问题 在加载窗口后重新渲染。
 $('a[data-toggle="pill"]').on('shown.bs.tab', function(e) {
 for(var i = 0; i < charts.length; i++) {
 charts[i].resize();
 }
 }); //data-toggle="pill还是data-toggle="tab" 根据前面所用标签页的不同来选择
//echarts自适应
 var charts = [];
 var chart1 = echarts.init(document.getElementById("left1"));
 var chart2 = echarts.init(document.getElementById("left2"));
 var chart3 = echarts.init(document.getElementById("right11"));
 var chart4 = echarts.init(document.getElementById("right12"));
 var chart5 = echarts.init(document.getElementById("right21"));
 var chart6 = echarts.init(document.getElementById("right22"));
 chart1.setOption(option1);
 chart2.setOption(option1);
 chart3.setOption(option2);
 chart4.setOption(option2);
 chart5.setOption(option1);
 chart6.setOption(option1);
 charts.push(chart1);
 charts.push(chart2);
 charts.push(chart3);
 charts.push(chart4);
 charts.push(chart5);
 charts.push(chart6);
 $(window).resize(function() {
 for(var i = 0; i < charts.length; i++) {
 charts[i].resize();
 }
 })

下面看一个实现的demo:

            demo 完成内容：

                                      1. bootstrap实现响应式布局

                                      2. echats实现自适应

                                      3. 标签页切换、缩放正常显示
