您好我有3个选择器,所有选择器都有一些带有一些值的选项,如何对所选选项的所有值求和？
<select name='anch1'> <option value='10'>10 ++</option> <option value='20'>20 ++</option> <option value='30'>30 ++</option> <option value='40'>40 ++</option> <option value='50'>50 ++</option> </select> <select name='anch2'> <option value='10'>10 ++</option> <option value='20'>20 ++</option> <option value='30'>30 ++</option> <option value='40'>40 ++</option> <option value='50'>50 ++</option> </select> <select name='anch3'> <option value='10'>10 ++</option> <option value='20'>20 ++</option> <option value='30'>30 ++</option> <option value='40'>40 ++</option> <option value='50'>50 ++</option> </select> <div>SUM OF SELECTED OPTIONS</div>
解决方法
$('select').change(function(){
var sum = 0;
$('select :selected').each(function() {
sum += Number($(this).val());
});
$("#sum").html(sum);
});
