How to Set Focus on Input Field using JQuery

Given the following HTML structure:

<div class="wrapper">
    <div class="top">
        <a href="http://example.com" class="link">click here</a>
    </div>
    <div class="middle">
        some text
    </div>
    <div class="bottom">
        <form>
            <input type="text" class="post">
            <input type="submit">
        </form>
    </div>
<div>

which will be repeated several times on the page, how do I set the focus on the input field in the .bottom div when a user clicks on the link in the .top div?

I am currently making the .bottom div appear successfully on click using the JQuery code below, but can't seem to figure out how to set focus on the input field at the same time.

$('.link').click(function() {
    $(this).parent().siblings('div.bottom').show();
});

Thanks!

Your question has been answered, but also: I assume you are also executing return false; at the end of the event callback? Or function(e) { e.preventDefault(); ..... }? If not, your browser will just navigate to that page after it executes the callback. - simshaun
@simshaun navigate to which page? - rolling stone
Well, in your example when you click that link it would go to example.com. - simshaun
oh, that's right, thanks for the heads up! - rolling stone

Try this, to set the focus to the first input field:

$(this).parent().siblings('div.bottom').find("input.post").focus();

If the input happens to be in a bootstrap modal dialog, the answer is different. Copying from How to Set focus to first text input in a bootstrap modal after shown this is what is required:

$('#myModal').on('shown.bs.modal', function () {
  $('#textareaID').focus();
})

Justin's answer did not work for me (Chromium 18, Firefox 43.0.1). jQuery's .focus() creates visual highlight, but text cursor does not appear in the field (jquery 3.1.0).

Inspired by https://www.sitepoint.com/jqueryhtml5-input-focus-cursor-positions/ , I added autofocus attribute to the input field and voila!

function addfield() {
    n=$('table tr').length;
    $('table').append('<tr><td><input name=field'+n+' autofocus></td><td><input name=value'+n+'></td></tr>');
    $('input[name="aa"'+n+']').focus();
}

//$GLOBALS['sitename'] is our domain site URL
//$_GET['s'] is the search parameter of our search, and we want to highlight that term searched...    
jQuery(document).ready(function($){  
        let loc=location.href;
        switch(loc) 
        {

    case "<?php echo $GLOBALS['sitename'] ?>?s=<?php echo $_GET['s'] ?>":       
        {       
        let searchf= $("form.search-form").find("input[type='search']:first");
//searchf.val('').focus();      
//empty the value to allow a new search and focus on the field....this works but better to highlight the searched term to allow the user to decide if want to type in something else or just hit again search. In case we want to empty the searched term 
           setTimeout(function (){
           searchf.delay(1000).focus().select(); 
           }, 1000);    
        break;
//.... end of relevant code 
        }
