jQuery slideDown with forms

问题

why the following code doesn't work? Under Opera it show just a black line for a second where the div should be, Under IE it shows div for 1 second, under FF nothing happens.

function showAdvanced(){
$("#advanced").slideDown("slow");
};

<div id="content">
  <form action="mycontrolleraddress" method="post" accept-charset="utf-8" name="search_form" id="search_form">
  <input type="text" name="query" value="" style="width:300px;font-size:18pt;border-color:#0080FF;border-width:2px;border-style:solid;background-color:#F2F2F2;"  />  
  <a href="" onclick="showAdvanced();" style="font-size:8pt;font-color:blue;">Advanced options</a>
  <br/>
  <div id="advanced" style="position:relative;height:400px;">From: 
    <input type="text" name="date_from" value="" id="datepicker" onchange="validateDate();" class="datefield"  /> To: 
    <input type="text" name="date_to" value="" id="datepicker2" onchange="validateDate();" class="datefield"  /> 
    <input type="text" name="limit" value="Results limit"  />
  </div>
  <input type="submit" name="submit" value="Szukaj"  />           
</div>

It's basically a textbox for search query, and I want advanced options (two data pickers and textbox) to appear after clicking a link.

回答1:

Is your script inside <script> tags, in <head>? Make sure it looks something like this: http://jsfiddle.net/bJQVa/. Note that I also set #advanced to be hidden by default.

NOTE: I also added a # for the href and a return false in the function.

        };

        $(document).ready(function(){
            console.log('document is ready');
        });

    </script>
</head>

<div id="content">
<form action="mycontrolleraddress" method="post" accept-charset="utf-8" name="search_form" id="search_form">

<input type="text" name="query" value=""/><br/>

<a href="#" onclick="showAdvanced();" style="font-size:8pt;font-color:blue;">Advanced options</a><br/>

<div id="advanced" style="display: none;">
    From: <input type="text" name="date_from" value="" id="datepicker" onchange="validateDate();" class="datefield"  /><br/>
    To: <input type="text" name="date_to" value="" id="datepicker2" onchange="validateDate();" class="datefield"  /> <br/>
    <input type="text" name="limit" value="Results limit"  />
</div>
<input type="submit" name="submit" value="Szukaj"  />

</div>

</body>
</html>

Working for me. Next time try to format your code better, so it will be more readable.
