javascript - It worked in jquery 1.3.0 but it will not work on 1.10.1 -


the goal onclick change input , displayed price. code below works in jquery 1.3.0 not in 1.10.1. missing? if there better way please let me know. 

$(document).ready(function () {     $("").click(update2); });  function update2() {     var myprice = $("#price").val();     $('#displayprice').html('price: ' + myprice + ''); }

html markup - 

<input type="hidden" name="price" id="price" class="item_price" value="$15.00"> </label> <div id="displayprice" name="displayprice" class="form_total">price: $25.00</div> <div class="xsshirt">     <input id="size5" class="product-attr-size" name="size" type="radio" value="xsmall" onclick="document.getelementbyid('price').value='$25.00'" />     <label for="xsmall"></label> </div> <div class="sshirt">     <input id="size1" class="product-attr-size" name="size" type="radio" value="small" onclick="document.getelementbyid('price').value='$25.00'" />     <label for="small"></label> </div> <div class="mshirt">     <input id="size2" class="product-attr-size" name="size" type="radio" value="medium" onclick="document.getelementbyid('price').value='$25.00'" />     <label for="medium"></label> </div> <div class="lshirt">     <input id="size3" class="product-attr-size" name="size" type="radio" value="large" checked="checked" onclick="document.getelementbyid('price').value='$25.00'" />     <label for="large"></label> </div> <div class="xlshirt">     <input id="size4" class="product-attr-size" name="size" type="radio" value="xlarge" onclick="document.getelementbyid('price').value='$30.00'" />     <label for="xlarge"></label> </div> </div>

in older versions of jquery, $("") , $() returned document, therefore current code binding click event document.

simply update selector target document.

$(document).click(...

or better, have target parent element closer target element (whatever target element is, surely don't want catch click events on document?)
