How to hide or remove options from jQuery Chosen select dropdown

问题

I would like to hide certain elements from a dropdown that is created using the Chosen plugin.

I have tried removing it:

$( 'option:contains("Swatch 1")').remove().trigger("chosen:updated");

and just hiding it:

$( '.chosen-results li:contains("Swatch 1")').css('display,'none');

But neither works.

See Colours dropdown: http://www.carolineelisa.com/test/wordpress/product/machine/

Any help appreciated :)

回答1:

In the original select you need to hide the option. For example:

$('select.chosen-select options:contains("Swatch 1")');

Then update the chosen options with:

$('select.chosen-select').trigger("chosen:updated");

If you have more than one chosen drop down on the page then it probably would be better to use a more specific id or class on that element in the place of $('select.chosen-select'). So your code would become:

$('#swatch_select options:contains("Swatch 1")');
$('#swatch_select').trigger("chosen:updated");

Here's a jquery snipped to deselect and update a chosen ddl that is designated as multiple. ddlID is the ID of the chosen ddl and ddlValue is the value property of the option.

$("#ddlID option[value='" + ddlValue + "']").prop('selected', false);
$("#ddlID").trigger("chosen:updated");

hide the option and update....

$('#button').click(function(){
        $('select#theIDselect > option[value="Swatch 1"]').hide();
        $('#theIDselect').trigger("chosen:updated");
    });

Small edit of kamijean's code:

 $('select.chosen-result option:contains("Swatch 1")').hide();
 $('select.chosen-result').trigger("chosen:updated");

so not chosen-select but chosen-result and not options but option

for selecting by values and not title use

 $('select.chosen-result option[value=830]').hide();
 $('select.chosen-result').trigger("chosen:updated");

You can hide with value or with class name. Check working code here.

<select id="dd_option" data-placeholder="Select one..." class="chzn-select" style="width:350px;" tabindex="2">
    <option value="all" selected="selected"> All </option>
    <option  value="mls" class="list_srch"> #MLS Number </option>
    <option  value="zip" class="list_srch"> Zip/Postal </option>
    <option value="title"> Listing Title </option>
    </select>
<button type="button" id="btn_hide_val">Hide with value</button>
<button type="button" id="btn_hide_class">Hide with class</button>
<button type="button" id="btn_unhide">Unhide</button>
<script>

$(".chzn-select").chosen();

$('#btn_hide_val').click(function() {

    // Just hide option #MLS Number,  Zip/Postal
    $("#dd_option option[value='mls']").hide();
    $("#dd_option option[value='zip']").hide();
    $("#dd_option").trigger("chosen:updated");
        
});
$('#btn_hide_class').click(function() {

    // Just hide option  #MLS Number,  Zip/Postal
    $("#dd_option option[class='list_srch']").hide();

    $("#dd_option").trigger("chosen:updated");
        
});
  
$('#btn_unhide').click(function() {

    // Just hide option 4
    $("#dd_option option[class='list_srch']").show();
        
    $("#dd_option").trigger("chosen:updated");
        
});

This works fine

jQuery( '.chosen-results li:contains("Swatch 1")').hide();

If you would like to use $ safely wrap your code with this

(function($) {

    // $ Works! You can test it with next line if you like
    // console.log($);

})( jQuery );
