I created a “More” link in my form, it runs well on Firefox and IE9, but behaves strangely on Chrome. It shows the #advanced_search in 5 clicks! (see the picture below). How can I fix it or determine where the error is?

Here is my HTML:
<form id="jp_search" enctype="application/x-www-form-urlencoded" action="" method="post">
<dl class="zend_form">
<input type="text" name="keyword" id="keyword" value="" class="txtinput" onfocus="if(this.value=='Keyword') this.value='';" onblur="if(this.value=='') this.value=('Keyword');">
<select name="category" id="category" class="jp_select">

<input type="submit" name="submit" id="jp_submit" value="">
<div class="advanced_search" id="advanced_search" style="display: block; ">

<input type="text" name="salary_max" id="salary_max" value="" class="txtinput" onfocus="if(this.value=='Max salary') this.value='';" onblur="if(this.value=='') this.value=('Max salary');">
</div>
</div>
</dl>
</form>
<div id="advanced_search_div">
<a href="#" id="advanced_search_show" title="More">› More</a>
</div>
Javascript :
$('#advanced_search_show').click(function(){
$('#advanced_search').toggle();
});
UPDATE: I found an issue with textbox focusing in Chrome, when I focus in a text box, it expand automatically the padding between two line. I highly appreciate any help ^_^. (I try to update this question in Chrome and it’s crashed >_<, I have to change to Firefox).
