I have two drop down menus. Option of second drop down are shown on the selection of first drop down.
It works perfect on chrome however on safari/iphone, it doesn't work. I searched around the web to find a fix and learned about safari doesn't let you hide the options. So I tried coming up with a solution, which seems to work somewhat but not quite. How can I fix adjust the code to correct this across all browsers?
// get first dropdown and bind change event handler
$('#p-city').change(function() {
// get optios of second dropdown and cache it
var $options = $('#p-nhb')
// update the dropdown value if necessary
.val('')
// get options
.find('option')
// show all of the initially
.show();
// IF SAFARI
if (navigator.userAgent.indexOf('Safari') != -1 && navigator.userAgent.indexOf('Chrome') == -1) {
var $options = $('#p-nhb').val('').find('option').append();
}
// check current value is not 0
if (this.value != '0')
$options
// filter out options which is not corresponds to the first option
.not('[data-val="' + this.value + '"],[data-val=""]')
// hide them
.hide();
// IF SAFARI
if (navigator.userAgent.indexOf('Safari') != -1 && navigator.userAgent.indexOf('Chrome') == -1) {
$options.not('[data-val="' + this.value + '"],[data-val=""]').detach();
}
})
$('#p-city').trigger('change');<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p>
<select name="property_city" id="p-city">
<option class="button" value="new-york-city" selected>New York City</option>
<option class="button" value="">All</option>
<option class="button" value="dallas-tx">Dallas, TX</option>
<option class="button" value="las-vegas">Las Vegas, NV</option>
<option class="button" value="los-angeles">Los Angeles, CA</option>
<option class="button" value="miami">Miami, FL</option>
<option class="button" value="new-york-city">New York City, NY</option>
<option class="button" value="san-francisco">San Francisco, CA</option>
<option class="button" value="seattle-wa">Seattle, WA</option>
</select>
</p>
<p>
<select name="property_nhb[]" id="p-nhb" multiple>
<option class="button">All</option>
<option data-val="los-angeles" value="beverly-hills" >Beverly Hills</option>
<option data-val="los-angeles" value="santa-monica" >Santa Monica</option>
<option data-val="miami" value="hialea" >Hialea</option>
<option data-val="miami" value="little-havana">Little Havana</option>
<option data-val="miami" value="north-miami">North Miami</option>
<option data-val="miami" value="south-beach">South Beach</option>
<option data-val="new-york-city" value="chelsea">Chelsea</option>
<option data-val="new-york-city" value="harlem">Harlem</option>
<option data-val="new-york-city" value="noho">NoHo</option>
<option data-val="new-york-city" value="soho">SoHo</option>
</select>
</p>UPDATE
I've noticed another function of mines also doesnt work in safari --
$("#search-tabs").on('click','li', function(e) {
$('.searchbox').hide().eq($(this).index()).show();
});
So I guess it's safe to say ".hide" and ".show" dont work in safari, what is a simple alternative without having to rewrite a bunch of code?
UPDATE 2
This works to for .hide (.show = 'block') but not for the select options -
.css('display', 'none');
UPDATE 3
The drop downs before rendered --
<select name="property_city" class="form-control" id="p-city">
<?php
$terms = get_terms( "city-type", array( 'parent' => 0, 'orderby' => 'slug', 'hide_empty' => 0 ) );
$count = count($terms);
if ( $count > 0 ){
echo "<option class='button' value='new-york-city'>New York City</option>";
echo "<option class='button' value=''>All</option>";
foreach ( $terms as $term ) {
echo "<option class='button' value='" . $term->slug . "'>" . $term->name . "</option>";
}
}
?>
</select>
<label>Neighborhood</label>
<?php $taxonomyName = "city-type";
$parent_terms = get_terms( $taxonomyName, array( 'parent' => 0, 'orderby' => 'slug', 'hide_empty' => false ) );
echo "<select name='property_nhb[]' class='form-control' id='p-nhb' style='border-left: 1px solid #000 !important;' multiple>";
echo "<option class='button'>All</option>";
foreach ( $parent_terms as $pterm ) {
//Get the Child terms
$terms = get_terms( $taxonomyName, array( 'parent' => $pterm->term_id, 'orderby' => 'slug', 'hide_empty' => false ) );
foreach ( $terms as $term ) {
echo "<option data-val='" . $pterm->slug . "' value='" . $term->slug . "'>" . $term->name . "</option>";
}
}
echo "</select>";
?>
