如何通过jQuery访问highstock缩放按钮？

Question

Is there a way to access highstock zoom buttons via jquery as follows

$('.highcharts-range-selector-buttons').attr('user', 'free');

I want to add a new attribute to the range selector buttons.

Yes, but you need to wait until the range selector is rendered. Eg it is rendered before load event, so you can grab the element there.

chart: {
  type: 'arearange',
  events: {
    load: function() {
      const el = $('.highcharts-range-selector-buttons').attr('user', 'free')
      console.log(el.attr('user'))
    }
  }
},

The class you have is for the group which includes buttons. Range selector buttons have classes highcharts-button [highcharts-button-pressed / highcharts-button-normal]
