javascript - Select a Child Object -


my experience javascript , jquery null, so...

i'm trying rotate object (div_sheet_item), , store actual rotation inside hidden input called "rotation".

i can't value of input calculate angle, , don't have idea why.

here's code:

javascript

$(document).ready(function() {   $('.div_sheet_item_rotate').click(function() {     var rotation = $(this).parent().find('rotation').val();     rotation += 90;     $(this).parent().rotate(rotation);   }); });

html

<li class="div_sheet_item" style="width: 330px; height: 230px;">   <div class="div_sheet_item_rotate"><img src="img/ico_rotate.png"/></div>   <input type="hidden" name="rotation" value="0" /> </li>  <li class="div_sheet_item" style="width: 330px; height: 230px;">   <div class="div_sheet_item_rotate"><img src="img/ico_rotate.png"/></div>   <input type="hidden" name="rotation" value="0" /> </li>  <li class="div_sheet_item" style="width: 330px; height: 230px;">   <div class="div_sheet_item_rotate"><img src="img/ico_rotate.png"/></div>   <input type="hidden" name="rotation" value="0" /> </li>

any great.

thanks

jquery .find() function takes selector argument. find input name, should use attribute equals selector:

parent().find('[name="rotation"]')

but better way assign class rotation input, , select class:

<input type="hidden" name="rotation" class="rotation" value="0" />  parent().find('.rotation')
