I would like to compare a input against li elements but for some reason it's only checking the last li element. You can see this when running the script below everything with "test" works fine but not for "example" or "example 2"
$(document).ready(function() { var $input = $('#autocomplete'); $(document).on('keyup', $input, function() { var $val = $input.val().trim(), $select = $('.autocomplete-content'); // Check if the input isn't empty if ($val != '') { $select.children('li').each(function() { var $li = $(this), $html = $li.html(), $text = $li.text().trim(); // Set input value $li.click(function() { $input.val($text); }); // Check if the value has at least 1 match else hide if ($text.indexOf($val) !== -1) { // Remove class hide when input changes and finds a match if ($li.hasClass('hide')) { $li.removeClass('hide'); } // Unhide "ul.autocomplete-content" if ($select.hasClass('hide')) { $select.removeClass('hide'); // Show options } } else { $li.addClass('hide'); $select.addClass('hide'); // Hide options } }); } else { $select.addClass('hide'); } }); });
.hide { display: none; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <input type="text" id="autocomplete" class="autocomplete"> <ul class="autocomplete-content hide"> <li><img src="test.jpg"> example</li> <li><img src="test.jpg"> example 2</li> <li><img src="test.jpg"> test</li> </ul>
So my question is how can I compare the input against each li element. Thanks in advance.
Update
Something I forgot to mention was that in the li
element could be an img
thats the reason why I used $li.text()
Instead of looping through all the li
's when anything is entered in the input, you can try to use the pseudo selector :contains
. This finds all elements with the text we have provided and if your intention is to find elements which starts with the search string, then you might need to improvise a little. This thread might be helpful.
$(document).ready(function() { var $input = $('#autocomplete'); $(document).on('keyup', $input, function() { var $val = $input.val().trim(), $select = $('.autocomplete-content'); // Check if the input isn't empty if ($val != '') { $select.children('li').addClass('hide') $select.children('li').filter(function() { console.log($(this).text().indexOf($val)) return $(this).text().indexOf($val) !== -1; }).removeClass('hide'); } else { $select.children().addClass('hide'); } }); });
.hide { display: none; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <input type="text" id="autocomplete" class="autocomplete"> <ul class="autocomplete-content"> <li class="hide"><img src="test.jpg"> example</li> <li class="hide"><img src="test.jpg"> example 2</li> <li class="hide"><img src="test.jpg"> test</li> </ul>
Need to remove $select.addClass('hide');
. It's called when the input does not match test
, even when it may match example
.
$(document).ready(function() { var $input = $('#autocomplete'); $(document).on('keyup', $input, function() { var $val = $input.val().trim(), $select = $('.autocomplete-content'); // Check if the input isn't empty if ($val != '') { $select.children('li').each(function() { var $li = $(this), $html = $li.html(), $text = $li.text().trim(); // Set input value $li.click(function() { $input.val($text); }); // Check if the value has at least 1 match else hide if ($text.indexOf($val) !== -1) { // Remove class hide when input changes and finds a match if ($li.hasClass('hide')) { $li.removeClass('hide'); } // Unhide "ul.autocomplete-content" if ($select.hasClass('hide')) { $select.removeClass('hide'); // Show options } } else { $li.addClass('hide'); //$select.addClass('hide'); // Hide options } }); } else { $select.addClass('hide'); } }); });
.hide { display: none; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <input type="text" id="autocomplete" class="autocomplete"> <ul class="autocomplete-content hide"> <li>example</li> <li>example 2</li> <li>test</li> </ul>
You have to set class hide
to li
instead of ul
On keyup
event of #autocomplete
iterate through the li
s, which one contains the textbox value remove class hide
from that and add class hide
which one not contains.
$(document).on('keyup', '#autocomplete', function () { var text = $(this).val(); $('.autocomplete-content li').each(function () { if ($(this).text().trim().indexOf(text) > -1) { $(this).removeClass('hide'); } else { $(this).addClass('hide'); } }); });
.hide { display: none; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <input type="text" id="autocomplete" class="autocomplete"> <ul class="autocomplete-content"> <li class="hide"><img src="test.jpg"> example</li> <li class="hide"><img src="test.jpg"> example 2</li> <li class="hide"><img src="test.jpg"> test</li> </ul>
