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);
- });
