Unable to activate focus() on a specific text field

It's quite peculiar. I'm working with a Sammy.js application, and my goal is to set the focus on a text field as soon as the HTML loads. Here's the CoffeeScript code snippet I've written:

this.partial('templates/my-template.jqt').then ->
  i = $('#item')
  debugger
  i.focus()

During the debug session, right at that line, I can examine "i" and confirm that it's a JQuery object. Surprisingly, I am able to update the text field by calling i.val("HI THERE!"). However, the command i.focus() seems to have no effect whatsoever. Could there be a security feature preventing me from focusing on a dynamically loaded text element?

Answer №1

Give this a shot:

setTimeout(function() { $('#item').focus() }, 1);

It's a common problem that can often be solved by introducing a slight delay in focusing the element.

Answer №2

The focus() method in JQuery does not actually set focus on an element; instead, it attaches an event handler for when the element receives focus. http://api.jquery.com/focus/

For setting focus on an element, you may try using i.get().focus() as an alternative.

Answer №3

If you're confident that you've obtained the $('#item') object, there are a few things you can experiment with.

Ensure that you have only one input box with 

<input type="text" id="item" />
. The same ID should not be used more than once.

Another suggestion is to try using $('#item').focus().

Thank you. Best regards,

Answer №4

Follow these steps:

i.click()
