Question

I want to programmatically change the title of my Bootstrap-select selectpicker.

I tried the following JS code which does not work.

$('#myPicker')
    .selectpicker({title: 'New title'})
    .selectpicker('render');

Any other ways I can do this?

Answer 1

Selectpicker仅在DOM已更新时才会更新。下面的函数应该更新标题，因为它允许selectpicker附加一个新的html对象（DOM被更改）

function newTitle() {
    var selectpicker = $("#myPicker");
    selectpicker.selectpicker();
    selectpicker.selectpicker({title: 'New Title'}).selectpicker('render');
    html = '';
    selectpicker.html(html);
    selectpicker.selectpicker("refresh");
}

Answer 2

The posted code does seem to work in the snippet.

$(document).ready(function() {
  $('#myPicker2')
    .selectpicker({
      title: 'New title'
    });
});
