javascript - jQuery find previous button by ID (which will have different names) -


hey trying previous button can change text else once selects value select box.

<div class="input-group">     <div class="input-group-btn search-panel">         <button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">             <span id="search_concept">type</span> <span class="caret"></span>         </button>         <ul class="dropdown-menu" id="dd1" role="menu">              <li><a href="#" data-info="blah1">for sale</a></li>              <li><a href="#" data-info="blah1">wanted</a></li>         </ul>     </div>     <div class="input-group-btn search-panel">         <button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">             <span id="search_concept">location</span> <span class="caret"></span>         </button>         <ul class="dropdown-menu" id="dd2" role="menu">              <li><a href="#" data-info="somewhere">somewhere</a></li>              <li><a href="#" data-info="elsewhere">elsewhere</a></li>         </ul>     </div>     <input type="text" class="form-control" name="x" placeholder="search term..."> </div>  $('.search-panel #dd1, .search-panel #dd2').find('a').click(function(e) {     e.preventdefault();     var param = $(this).data("info");      $(this).prev().find('#search_concept').text($(this).text()); });

so click event starts this a href="#" data-info="blah1">[value here]< /a> tag. trying go < button> tag can change text type whatever selected.

i've tried:

$(this).prev().find('#search_concept').text($(this).text()); , $(this).prev().prev().find('#search_concept').text($(this).text()); , $(this).prev().prev().children().find('#search_concept').text($(this).text()); , $(this).prev().children().find('#search_concept').text($(this).text());

and can't seem find it....

fixed

$('.search-panel #dd1, .search-panel #dd2').find('a').click(function(e) {     e.preventdefault();     var param = $(this).data("info");      $(this).parents('.search-panel').find('button').html($(this).text() + ' <span class="caret"></span>'); });

the following snippet uses jquery's .parents locate button.

$(this).parents(selector) find parent elements have specified selector.

then .find(selector) search parent element specified selector.

then can assign variable , use element.

$('.search-panel #dd1').find('a').click(function(e) {    e.preventdefault();    var param = $(this).data("info");    var text = $(this).text();      // assign element variable later manipulation    var $button = $(this).parents('.search-panel').find('button');      // eg: replace button text (replaces content including html)    // $button.text(text)      // eg: find element inside $button , replace text    // $button.find('#search_concept').text(text)  });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <div class="input-group">      <div class="input-group-btn search-panel">          <button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">              <span id="search_concept">type</span> <span class="caret"></span>          </button>          <ul class="dropdown-menu" id="dd1" role="menu">               <li><a href="#" data-info="blah1">for sale</a></li>               <li><a href="#" data-info="blah1">wanted</a></li>          </ul>      </div>      <input type="text" class="form-control" name="x" placeholder="search term...">  </div>
