javascript - Conditionally showing options in a select with Angular -


i creating template showing select fields in app. have 4 different types of select field. value = id, value = name, value = static_id , value = static_name (it's complicated...).

i plan migrate these ngoptions if possible in future, attempting have single select template, handle 4 types of field.

i use ng-if show different 'static' code select, creates lot of code want reduce single template.

here's code:

// shows basic select field option value = id <div ng-if="field.type=='select'" class="form-group">     <select-field></select-field> </div>  // shows basic select field option value = name <div ng-if="field.type=='select_name'" class="form-group">     <select-field></select-field> </div>  // shows basic select field option value = static_id <div ng-if="field.type=='select_static_id'" class="form-group">     <select-field></select-field> </div>  // shows basic select field option value = static_name <div ng-if="field.type=='select_static_name'" class="form-group">     <select-field></select-field> </div>

here, field attributes identical, except generated options. hence why want template this.

i attempting have single template have ng-if inside detect field type, json reads, , change options displayed accordingly, (2 of 4 examples shown):

<select      name={{field.name}}      class="form-control form-field {{relationshipurl}}"     id={{field.name}}      data-is-autofocus={{field.focus}}      data-selectreq={{field.rules.selectreq}}      data-showhide={{field.rules.showhide}} >     <option value="" selected>please select...</option>     <span ng-if="field.type=='select'">              <option              value={{option.id}}              ng-repeat="option in cache[field.relationshipurl] | orderby:'name || firstname'"              ng-selected="formdata[field.name] == option.id">                 {{option.name || option.firstname}}         </option>     </span>     <span ng-if="field.type=='select_static_name'">         <option              value={{option.name}}              ng-repeat="option in cache[field.relationshipurl] | orderby:'name'"             ng-selected="formdata[field.name] == option.name">                 {{option.name}}         </option>     </span> </select>

possibly horrible code use span within select, that's why coming people. works in shows correct options, however, shows options listed out twice, , assume list them 4 times once option types included. hope makes sense. in advance.

well no sooner had posted, answer blindingly obvious. instead of above approach removing span , putting ng-if on <option> instead fixed issue , works perfectly!

<select      name={{field.name}}      class="form-control form-field {{relationshipurl}}"     id={{field.name}}      data-is-autofocus={{field.focus}}      data-selectreq={{field.rules.selectreq}}      data-showhide={{field.rules.showhide}} >     <option value="" selected>please select...</option>      <option ng-if="field.type=='select'"         value={{option.id}}          ng-repeat="option in cache[field.relationshipurl] | orderby:'name || firstname'"          ng-selected="formdata[field.name] == option.id">             {{option.name || option.firstname}}     </option>     <option ng-if="field.type=='select_name'"         value={{option.name}}          ng-repeat="option in cache[field.relationshipurl] | orderby:'name'"         ng-selected="formdata[field.name] == option.name" >             {{option.name}}     </option>     <option ng-if="field.type=='select_static_id'"         value={{option.id}}          ng-repeat="option in cache[field.relationshipurl] | orderby:'name'"         ng-selected="formdata[field.name] == option.id" >             {{option.name}}     </option>     <option ng-if="field.type=='select_static_name'"         value={{option.name}}          ng-repeat="option in cache[field.relationshipurl] | orderby:'name'"         ng-selected="formdata[field.name] == option.name">             {{option.name}}     </option> </select>
