A drop-down menu using jquery [like Yahoo]

I saw a very nice drop-down menu in Yahoo mail, and I made a pig.

There is a small bug in it .. That is, after the menu appears, click somewhere else and the menu disappears, but you need to click it twice,
Mainly because the code is <a href = "http://www.zzcn.net/"> navigation <span id = "dh1"> navigation </span> </a>
It is caused by this structure, but I cannot change this structure, or the effect is incorrect ..

After the struggle .. I found that there was a bug in the code just now. I hereby fix the bug. In order to remember the above error, I will not delete it. (The code below also contains the bug code, but peng won't delete it here .)

I have put the code on my website .. You can directly view the results and click here

The following code is a part of the code that is occasionally written (the code below contains the bug, please download navi2 for the correct code ).. Haha .. Jquery uses 1.2.6.

$ (Document). Ready (function (){
VaR d1x_click = false;

$ ("Body"). Not ($ ("# d1x"). Click (function (){
If (! D1x_click)
{
$ ("# D1x" ).css ("display", "NONE ");
}
D1x_click = false;
// Alert ("B ");

})
$ ("# D1x"). Click (function (){
D1x_click = true;
});
$ ("# Dh1"). Click (function (){
// Alert ("C ");
VaR offset = $ ("# d1"). offset ();
VaR d1x = $ ("# d1x ");
If(d1x.css ("display") = "Block ")
{
D1x.css ("display", "NONE ");
}
Else
{
D1x.css ("display", "Block ");
}
D1x.css ("position", "absolute ");
D1x.css ("Left", offset. Left );
D1x.css ("TOP", offset. Top + $ ("# d1"). Height () + 3 );
D1x_click = true;
Return false;
});
});
