This article mainly introduces to you the relevant information about the js data interaction of four charts in the same page of echarts. The article gives a complete sample code for your reference and study, which is of certain significance to your study or work. Help, friends in need come and learn together

Requirements:

Click on the tab page to switch four different charts, ajax to The background request data is displayed in four different charts.

I won’t say much about the rest, just go to the js code

Sample code:

 $("#heart").on("click", function() {

  $(&#39;.heart-car&#39;).show();
  $(&#39;.sleep-car&#39;).hide();
  $(&#39;.breathe-car&#39;).hide();
  $(&#39;.sport-car&#39;).hide();

 });

 $("#breathe").on("click", function() {

  $(&#39;.heart-car&#39;).hide();
  $(&#39;.sleep-car&#39;).hide();
  $(&#39;.breathe-car&#39;).show();
  $(&#39;.sport-car&#39;).hide();
 });
 $("#sport").on("click", function() {

  $(&#39;.heart-car&#39;).hide();
  $(&#39;.sleep-car&#39;).hide();
  $(&#39;.breathe-car&#39;).hide();
  $(&#39;.sport-car&#39;).show();

 });
 $("#sleep").on("click", function() {

  $(&#39;.heart-car&#39;).hide();
  $(&#39;.sleep-car&#39;).show();
  $(&#39;.breathe-car&#39;).hide();
  $(&#39;.sport-car&#39;).hide();

 });
