javascript - ignore value of select option jQuery -



javascript - ignore value of select option jQuery -

this quite simple wondering how ignore value option select if equal value, illustration have select

<select> <option value="">all</option> <option value=".dog">dog</option> <option value=".cat">cat</option> </select> $('select').on('change', function() { var animal_type = $('option:selected').text(); });

so if 'all' selected not want assign animal_type variable in next ajax post animal_type disregarded , not sent parameter

$.ajax({ type: 'post', url: '/public/rehomed', data: { animal_type: animal_type, #so if selected should not passed through rehomed: false, } });

the reason thinking remove animal_type variable ajax post parameters of post create sql query on server side me in rails.

add status check value of selected alternative before ajax.

$('select').on('change', function() { var animal_type = $('option:selected').text(); var data_send = {animal_type: animal_type, rehomed: false,}; if(animal_type != "all"){ data_send = {rehomed: false,}; } $.ajax({ type: 'post', url: '/public/rehomed', data: data_send, }); });
