javascript - jQuery get the total position from an id -

-

i want set focus position on variable #id after ajax reloads content within container. container has overflow:auto; in see scrollbar if content large. after inserting new content, can't focus set on #id i'm giving set on.

i first tried set focus on id:

<script type="text/javascript"> function setfocus(ulid) {   var heightul = $("#"+ulid).offset();   $("#"+ulid).focus(); } </script>

later tried total height of id, put offset() on it, $("#"+ulid).offset().top; or $("#"+ulid).position().top;.

function setfocus(ulid) {   var heightul = $("#"+ulid).offset().top;   $("#"+ulid).stop().animate({ scrolltop: heightul }, 'fast'); }

but isn't working either. position() 0 in return , offset() returns object's height relative parent. , not total height object positioned within container.

the html:

<div class="info-container edit" id="info-container-edit">   <span class="cat">info 1</span>   <ul id="info1" class="cat-list music">     <li>...</li>     <li>...</li>     <li>...</li>     <li>...</li>   </ul>   <span class="cat cat">info 2</span>   <ul id="info2" class="cat-list music">     <li>...</li>     <li>...</li>     <li>...</li>     <li>...</li>   </ul>   <span class="cat cat">info 3</span>   <ul id="info3" class="cat-list music">     <li>...</li>     <li>...</li>     <li>...</li>     <li>...</li>   </ul>   <span class="cat cat">info 4</span>   <ul id="info4" class="cat-list music">     <li>...</li>     <li>...</li>     <li>...</li>     <li>...</li>   </ul> </div>

the ajax code refreshes container #info-container-edit. problem example want focus on #info3 setfocus('info3');. seems returns height of #info2 , not total height container #info-container-edit till #info3.

can point out how fix problem? if can position height of #id within container, should problem fixed. or how set display focus on #id?

you use .scrollintoview():

document.getelementbyid(ulid).scrollintoview(false);
