javascript - Bootstrap Validator & Image Picker - How to validate form if any one of two available select inputs are chosen? -

-

i using bootstrap-validator form validation, , imagepicker display selects. works great, have come across instance can't solve on own. have form 2 inputs , need form validate if of 2 inputs selected. couldn't find example on bootstrap-validator or imagepicker options

ideally i'd accomplish bootstrap-validator or imagepicker plugin. if not i'll if statement toggle required property.

here form, appreciated. thanks

html

<form role="form">        <h4>select list #1</h4>        <div class="form-group">         <label class="hide" for="select-list-1">select list #1</label>         <select id="select-list-1" multiple="multiple" class="image-picker form-control" required>           <option>option 1</option>           <option>option 2</option>           <option>option 3</option>         </select>       </div>        <h4>select list #2</h4>        <div class="form-group">         <label class="hide" for="select-list-2">select list #2</label>         <select id="select-list-2" multiple="multiple" class="image-picker form-control" required>           <option>option 1</option>           <option>option 2</option>           <option>option 3</option>         </select>       </div>          <button type="submit" class="btn btn-default action-btn">submit</button>     </form>

so decided best way not use bootstrap-validator on form. used clicked callback function in imagepicker determine if of images selected. made button disabled default , toggled depending if images selected or not.

//image picker $("form select").imagepicker({     show_label: true,     clicked: function(){         if($('form .thumbnails li div').hasclass('selected')){             //             $("form button").removeclass('disabled');         } else {             // else             $("form button:not('.disabled')").addclass('disabled');         }     } });

ok, know if have character '-' , want remove in places in string javascript, ... someword = someword.replace(/-/g, ''); but, when applying array of characters, s not working ... const badchars = ('\/:*?"<>|').split(''); let filename = title.replace(/ /g, '-').tolocalelowercase(); (let item = 0; item < badchars.length; item++) { // below not work global '/ /g' filename = filename.replace(/badchars[item]/g, ''); } any ideas? /badchars[item]/g looks badchars , literally, followed i , t , e , or m . if you're trying use character badchars[item] , you'll need use regexp constructor, , you'll need escape regex-specific characters. escaping regular expression has been well-covered . using that: filename = filename.replace(new regexp(regexp.quote(badchars[item]), 'g'), ''); but , don't want that. want character class: let filename = title.replac
