Question

I'm trying to close a div settings his opacity to 0. But it doesn't work

Here is my code:

HTML:

<div id='divinfo'  style='position:absolute; bottom:2px; right:8px; width:40px; height: 41px; '><img id='divinfo' ontouchstart='openhelp();return false;' src='img/button_settings_inactive.png'></img></div>


         <div id='janelaConfig' style="display:block; opacity:0.0; height:5px; position:absolute; width:50px; left:100px; top: 175px; background-color:white; padding:20px;">

             <div id="wrapper2">
                 <div id="scroller2">
                     <p>Escolha sua regiao </p>

jQuery:

function closehelp() {

    $("#janelaConfig").animate({
        width: "50px",
        height: "5px",
        top: "175px",
        left: "100px",
        opacity: 0.0

    }, 250);
    $("#lblStatus").text("");
    $("#fechar").hide();

    $("#divinfo").show();
};

function openhelp() {

    $("#janelaConfig").animate({
        width: "82%",
        height: "70%",
        top: "20px",
        left: "8px",
        opacity: 0.9

    }, 250, function () {
        $("#fechar").show();

    });

};

Solution 1

You can use --root to install packages into another directory, but you can't use most programs from there as most programs look for some files in fixed places (like /etc). The option is there for cases like installing packages into a NFS root for diskless clients.

Maybe you could use something like UnionFS to merge the two file systems.

Solution 2

If you want a simple answer that doesn't make you work your away around the debian package management, just use mount and symlinks. You could mount your external drive using /etc/fstab and have some symlinks that point into that drive. NOTE: You shouldn't blindly symlink, be sure before you change something ;)

A rather save suggestion would be to put your /tmp into a ramfs (which you should be doing anyways on many netbooks with SSD).

Are you sure your programs need the most space on your internal drive? Did you check it using a tool like xdiskusage?

Opacity will only work in firefox.

[Ladessa]

but work in mobile app. And work when I set to 1.0, but doesnt work when I reset to 0

[Ladessa]

I have too tried function closehelp() { $("#janelaConfig").animate({ width: "50px", height: "5px", top : "175px", left : "100px", opacity: 0.0 },250); $("#lblStatus").text(""); $("#fechar").hide(); $("#janelaConfig").hide(); $("#divinfo").show(); };

[xpy]

Can we see this live somehow?

[Ladessa]

When I use .hide, the div hide and appear again

[Ladessa]

I have created another div and put janelaConfig inside ..It works great

[cheshirekow]

Yeah, that's what I figured would be the problem. At first glance, UnionFS looks like it might work very well. I'll see if I can give that a try.

[cheshirekow]

So it appears that UnionFS was dropped from ubuntu since Karmic and replaced with unionfs-fuse (a fuse implementation rather than a kernal module). I like the idea of a kernel module better but this seems to be working quite well. This is, at least, exactly what I wanted so thanks for the good answer :).

[cheshirekow]

Ok, I'm un-answering this. UnionFS, it seems, is only a half answer. It does mostly what I want, but it appears that you can't unionfs two directories together, and then mount the union to one of the two.. which is what I would need. One way (possibly) to finish the answer would be to do something with a chroot? i.e. create a fakeroot as the union of the roots of each drive, and then chroot into that. Will this work? I don't know how to use chroot.

[Tobu]

aufs2 is what's used for union mounts in ubuntu livecds IIRC.

[Ladessa]

And I what I want is that the div be invisible

[xpy]

I mean, the elements will still be there and will be clickable/selectable.

[faino]

Good catch, display is a better way to handle it.

[Ladessa]

function closehelp(){$("#janelaConfig").animate({ width: "50px", height: "5px", top : "175px", left : "100px", opacity: 0.0,display:"none" },250); $("#lblStatus").text(""); $("#fechar").hide(); $("#divinfo").show(); };?

[James Donnelly]

Change $(this).hide() to $(this).css('display', 'none'); - does it work with this? If not, could you please show an example as I'm not sure why this wouldn't work otherwise!

[Ladessa]

Now it works better...the div flash...(disappear and appear again) but It is referenced only where I have posted in my answer...I have no ideia why the div appear again :S
