All of the methods in this chapter manipulate the DOM in some manner. A few of them simply change one of the attributes of an element (also listed in the Attributes category ), while others set an element’s style properties (also listed in the CSS category ). Still others modify entire elements (or groups of elements) themselves—inserting, copying, removing, and so on. All of these methods are referred to as “setters,” as they change the values of properties.
A few of these methods—such as .attr() , .html() , and .val() —also act as “getters,” retrieving information from DOM elements for later use.

ScrollTop

Get the current vertical position of the scroll bar for the first element in the set of matched elements.

<div>
<input type="button" id="btnScrollTop" value="Scroll Top [300]" />
<input type="button" id="btnScrollTopVal" value="Scroll Top Value" />
<div id="blockScrollTop" style="  background:#CCCCCC none repeat scroll 0 0;
                                   border:3px solid #666666;
                                   margin:5px;
                                   padding:5px;
                                   position:relative;
                                   width:200px;
                                   height:100px;
                                   overflow:auto;">
<p style="margin-top:300px;
          padding:5px;
          border:2px solid #666;
          width:1000px;
          height:1000px;">Hello</p>
</div>
<?php
echo
YsJQuery::newInstance()
  ->onClick()
  ->in('#btnScrollTop')
  ->execute(
    YsJQuery::scrollTop(300)->in('#blockScrollTop')
  )
?>
<?php
echo
YsJQuery::newInstance()
  ->onClick()
  ->in('#btnScrollTopVal')
  ->execute(
    sprintf('alert(%s)',YsJQuery::scrollTop()->in('#blockScrollTop'))
  )

</div>
