Liste déroulante des signets avec saisie semi-automatique

Question

J'ai besoin de js pour créer un bookmarklet afin de remplir un formulaire. va ici le code HTML:

<tr> 
    <td>Gender</td> 
    <td> 
     <div class="select2-container select2-container-active" id="s2id_ContentPlaceHolder1_personDetails_genderDropDownList"> 
     <a href="javascript:void(0)" class="select2-choice select2-default" tabindex="-1"> 
      <span class="select2-chosen" id="select2-chosen-2">Select an Option</span> 
       <abbr class="select2-search-choice-close"></abbr> 
        <span class="select2-arrow" role="presentation"> <b role="presentation"></b></span></a> 
         <label for="s2id_autogen2" class="select2-offscreen"></label> 
          <input class="select2-focusser select2-offscreen" type="text" aria-haspopup="true" role="button" aria-labelledby="select2-chosen-2" id="s2id_autogen2" tabindex="0" autocomplete="Female"> 
     </div> 
     <select name="_ctl0:ContentPlaceHolder1:personDetails:genderDropDownList" id="ContentPlaceHolder1_personDetails_genderDropDownList" onchange="nzis.UpdateDropdownErrorLabel(this)" errorlabel="mandatory" tabindex="-1" title="" style="display: none;"> 
     <option selected="selected" value=""></option> 
     <option value="M">Male</option> 
     <option value="F">Female</option> 
     </select> 
    </td> 
</tr> 

J'ai essayé avec quelques JS sans succès. JS:

var index = document.getElementById('ContentPlaceHolder1_personDetails_genderDropDownList').selectedIndex; 
    alert("value="+document.getElementById('ContentPlaceHolder1_personDetails_genderDropDownList').value); 
    alert("text="+document.getElementById('ContentPlaceHolder1_personDetails_genderDropDownList').options[1].text); 
s2id_autogen2.value= document.getElementById('ContentPlaceHolder1_personDetails_genderDropDownList').options[2].text;

Essayez d'exécuter le bookmarklet comme celui-ci:

javascript: (function() { 
    var eltSelect = document.getElementById('ContentPlaceHolder1_personDetails_genderDropDownList'); 
    eltSelect.options[2].selected = true; 
    eltSelect.onchange(); 
    s2id_autogen2.value = eltSelect.options[eltSelect.selectedIndex].text; 
})();
