Jquery – select2 force focus on page load

jqueryjquery-select2

I am trying to make a select2 box appear in its focused state on page load. I have tried the following:

$('#id').select2('focus');
$('#id').trigger('click');
$('#id').trigger('focus');

Only the first line seems to have any effect, and it does focus the select2 field, however it requires an additional keypress to display the search field, and to allow typing in search string.

Therefore, if you load the page and start typing: "Search", the "S" will open the search box and then the remainder of the keys will be entered into it, so you'll be searching "earch"

According to the Select2 documentation:

$('#id').select2('open');

Should be all you need.

Found under the Programmatic Access section in the documentation.

Javascript – Trigger a keypress/keydown/keyup event in JS/jQuery

You can trigger any of the events with a direct call to them, like this:

$(function() {
    $('item').keydown();
    $('item').keypress();
    $('item').keyup();
    $('item').blur();
});

Does that do what you're trying to do?

You should probably also trigger .focus() and potentially .change()

If you want to trigger the key-events with specific keys, you can do so like this:

$(function() {
    var e = $.Event('keypress');
    e.which = 65; // Character 'A'
    $('item').trigger(e);
});

There is some interesting discussion of the keypress events here: jQuery Event Keypress: Which key was pressed?, specifically regarding cross-browser compatability with the .which property.

Javascript – Get the size of the screen, current web page and browser window

You can get the size of the window or document with jQuery:

// Size of browser viewport.
$(window).height();
$(window).width();

// Size of HTML document (same as pageHeight/pageWidth in screenshot).
$(document).height();
$(document).width();

For screen size you can use the screen object:

window.screen.height;
window.screen.width;
