I’m trying to empty select options when:
id “mClick” is selected, id’s “sClick”, “cClick” & “srClick” will be emptied.
id “sClick” is selected, id’s “cClick” & “srClick” will be emptied.
id “cClick” is selected, id “srClick” will be emptied.
<form action="javascript:void(0);" method="POST" id="lForm"><table> <tr> <td> <select name="module" id="mClick"> <option value="">Select Mod</option> <option value="1">Mod 1</option> <option value="2">Mod 2</option> <option value="3">Mod 3</option> </select> </td> <td> <select name="state" id="sClick"> <option value="">Select State</option> <option value="1">State 1</option> <option value="2">State 2</option> </select> </td> <td> <select name="city" id="cClick"> <option value="">Select City</option> <option value="1">City 1</option> <option value="2">City 2</option> </select> </td> <td> <select name="services" id="srClick"> <option value="">Select Services</option> <option value="1">Services 1</option> <option value="2">Services 2</option> </select> </td> </tr></table>
in scenario 3, i used this function, yet it deleted all, except the last select. Any idea’s what i’m missing? Thanks
$('#lForm select[id!="mClick"] select[id!="sClick"] select[id!="cClick"] option[value!=""]').remove().end();The easiest way to clear the options in the way you’re describing is by using options.length = 1. Also, you can leverage the fact that each drop down clears the ones that logically follow it, so that you only need to declare a single alter handler.
$('#lForm select').on('change', function() { if (this.selectedIndex > 0) { var $others = $(this).closest('table').find('select'), current = $others.index(this); // find current while (++current < $others.length) { // for each following drop down $others.get(current).options.length = 1; } }});I’m not sure how you’re going to repopulate the drop downs though 🙂
