How to dynamic filter options of <select > with jQuery?
<select >
<option value="something">something</option>
<option value="something_else">something else</option>
</select>
<input type="text" >
So that when user inputs something, only options with value matching the input will show.
Solution 1:
Example HTML:
//jQuery extension method:
jQuery.fn.filterByText = function(textbox) {
return this.each(function() {
var select = this;
var options = [];
$(select).find('option').each(function() {
options.push({
value: $(this).val(),
text: $(this).text()
});
});
$(select).data('options', options);
$(textbox).bind('change keyup', function() {
var options = $(select).empty().data('options');
var search = $.trim($(this).val());
var regex = new RegExp(search, "gi");
$.each(options, function(i) {
var option = options[i];
if (option.text.match(regex) !== null) {
$(select).append(
$('<option>').text(option.text).val(option.value)
);
}
});
});
});
};
// You could use it like this:
$(function() {
$('select').filterByText($('input'));
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select>
<option value="hello">hello</option>
<option value="world">world</option>
<option value="lorem">lorem</option>
<option value="ipsum">ipsum</option>
<option value="lorem ipsum">lorem ipsum</option>
</select>
<input type="text">Live demo here: http://www.lessanvaezi.com/filter-select-list-options/
Solution 2:
I'm not sure why you have more than one option with the same value, but this works
$(document).ready(function() {
$('input').change(function() {
var filter = $(this).val();
$('option').each(function() {
if ($(this).val() == filter) {
$(this).show();
} else {
$(this).hide();
}
$('select').val(filter);
})
})
})<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select>
<option value="something1">something1</option>
<option value="something1">something1</option>
<option value="something2">something2</option>
<option value="something2">something2</option>
<option value="something2">something2</option>
<option value="something3">something3</option>
<option value="something3">something3</option>
<option value="something3">something3</option>
</select>
<input type="text" placeholder="something1">Solution 3:
Slightly different to all the other but I think this is the most simple:
$(document).ready(function(){
var $this, i, filter,
$input = $('#my_other_id'),
$options = $('#my_id').find('option');
$input.keyup(function(){
filter = $(this).val();
i = 1;
$options.each(function(){
$this = $(this);
$this.removeAttr('selected');
if ($this.text().indexOf(filter) != -1) {
$this.show();
if(i == 1){
$this.attr('selected', 'selected');
}
i++;
} else {
$this.hide();
}
});
});
});
Solution 4:
Much simpler code then most of the other solutions. Look for the text (case insensitive) and use CSS to hide/show the contents. Much better than storing a copy of the data.
Pass into this method the id of the select box, and id of the input containing a filter.
function FilterSelectList(selectListId, filterId)
{
var filter = $("#" + filterId).val();
filter = filter.toUpperCase();
var options = $("#" + selectListId + " option");
for (var i = 0; i < options.length; i++)
{
if (options[i].text.toUpperCase().indexOf(filter) < 0)
$(options[i]).css("display", "none");
else
$(options[i]).css("display", "block");
}
};
