如何使用 jquery 在 Bootstrap 5 中创建和修改弹出框？

Question

Does someone know how I can create and add data to bootstrap 5 popover via javascript/jquery?

With bootstrap 3 I was able to do this:

$('#element').popover({ placement : 'left', trigger : 'focus', html: true });
let content_template = `<h1>Hello World!</h1>`;
$('#element').data('bs.popover').options.content = content_template;

But I can't figure out how I can do the same with bootstrap 5. The documentation doesn't mention anything about this. Does anyone know how popovers are managed in BS5?

You need to get instance of popover and then use popover_instance._config.content ="some message" to set new content inside your popover .

Demo Code :

 new bootstrap.Popover(document.querySelector('[data-bs-toggle]'), { placement: 'left', trigger: 'focus', html: true }) //get instance var popover_instance = bootstrap.Popover.getInstance(document.querySelector('[data-bs-toggle]')) let content_template = `<h1>Hello World!</h1>`; popover_instance._config.content = content_template;//set content

The popover instance is returned from instantiation. You can then use this to modify the content...

const bsPopover = new bootstrap.Popover(document.querySelector('[data-bs-toggle]'), {
  placement: 'left',
  trigger: 'focus',
  html: true
})

bsPopover._config.content = `<h1>Hello World!</h1>`

If you plan on updating popover content multiple times you also need to call setContent() on popover instance. Like this

popoverInstance._config.content = "Hello world";
popoverInstance.setContent();
