How do you refresh an HTML5 datalist using JavaScript?

Question

I\'m loading options into an HTML5 datalist element dynamically. However, the browser attempts to show the datalist before the options have loaded.

Answer 1

I found a solution tested only on GNOME Web (WebKit) that consist on set the 'list' attribute of the input element to empty string and, inmediately after, set it again with the id of the datalist element. Here is the example, supose that your input element is stored in a variable named input_element:

var datalist = document.getElementById(input_element.list.id);
// at this point input_element.list.id is equals to datalist.id
// ... update datalist element here
// And now the trick:
input_element.setAttribute('list','')
input_element.setAttribute('list',datalist.id)
