Free Nodelet Hack: Collapse/expand Nodelets individually

in reply to Free Nodelet freed

The following hack makes each nodelet title clickable, and you can preconfigure your nodelet's initial state (collapsed/expanded).

Plunge into your Free nodelet and tweak the closedN array. For maximum benefit put your free nodelet last in Nodelet Settings.

update: use the block further down. I would have deleted this first attempt, had ikegami not answered :-)

// this function toggles a nodelet's state. function toggleVis (id) { var r = document.getElementById(id); if(r.style.display == "none") { r.style.display = "table-row"; } else { r.style.display = "none"; } } // Array with nodelet state flags, 1 = closed, 0 = open var closedN = `[1,1,0,1,1,1,1,1,1,1,1,1,1,1,1,1,1]; var nc = document.getElementById('nodelet_container'); var c = 0; for(var i=0; i<nc.childNodes.length; i++) { if(nc.childNodes`[i].nodeName == "TBODY") { cn = nc.childNodes`[i]; var ary = new Array; var k = 0; for(var j=0; j<cn.childNodes.length; j++) { if(cn.childNodes`[j].nodeName=="TR") { ary`[k] = cn.childNodes`[j]; k++; } } var str= ary`[0].childNodes`[1].innerHTML; var id = ary`[1].id; id = id.replace(/\'/,"\\'"); ary`[0].childNodes`[1].innerHTML = '<div onClick="toggleVis('+"'"+id+"'"+');">'+ary`[0].childNo +des`[1].innerHTML+'</div>'; if(closedN`[c]) toggleVis(ary`[1].id); c++; } }

That could've been more 'elegant'... but it's a hack. If JavaScript had hashes...

This one is for firefox. IE users likely will have to replace the document.getElemetById by the appropriate IE function.

<update>

Since some nodelets come and go, the order can change. Here's a version with hashes. The XP Nodelet has a degree sign in the upper left corner, which, when clicked, will pin/unpin the nodelet container. Use with the CSS snippet below.

// this function toggles a nodelet's state. function toggleVis (id) { var r = document.getElementById(id); if(!r.style.display || r.style.display == "none") { r.style.display = "table-row"; } else { r.style.display = "none"; } } function togglePin () { var n = document.getElementById('nodelet_container'); var pin = document.getElementById('nodelet_pin'); if (!n.style.position || n.style.position == 'fixed') { n.style.position = 'absolute'; pin.innerHTML = '&nbsp;|&nbsp;'; } else { n.style.position = 'fixed'; pin.innerHTML = '&nbsp;&deg;&nbsp;'; } } function collapseNodelets () { // insert the nodelets you want to have expanded here var opened = { 'XP Nodelet' : 0, 'Chatterbox' : 0, 'Tick tock' : 0, 'Cabalists\' Nodelet' : 1, } var nc = document.getElementById('nodelet_container'); var c = 0; for(var i=0; i<nc.childNodes.length; i++) { if(nc.childNodes`[i].nodeName == "TBODY") { cn = nc.childNodes`[i]; var ary = new Array; var k = 0; for(var j=0; j<cn.childNodes.length; j++) { if(cn.childNodes`[j].nodeName=="TR") { ary`[k] = cn.childNodes`[j]; k++; } } var str= ary`[0].childNodes`[1].innerHTML; str = str.replace(/ *\n */g,""); str = str.replace(/ /g," "); var id = ary`[1].id; id = id.replace(/\'/,"\\'"); if(str == "Chatterbox") { // this one gets the pin div - degree(pinned) or pipe(unpinned +) ary`[0].childNodes`[1].innerHTML = '<div id="nodelet_pin" onClick="togglePin();"' + ' style="float: left; cursor: pointer">&nbsp;&deg;&nbsp;</ +div>' + '<div onClick="toggleVis('+"'"+id+"'"+');">'+str+'</div>'; } else { ary`[0].childNodes`[1].innerHTML = '<div onClick="toggleVis('+"'"+id+"'"+');">'+str+'</div>'; } if(!opened`[str]) toggleVis(ary`[1].id); c++; } } } collapseNodelets();

And here's a stylesheet snippet to pin the nodelet container to the upper right corner of the page:

/* pin container, make it fixed width */ #nodelet_container { position: fixed; margin-left: 5px; top: 5px; width: 200px; } /* leave a bit space on the right, so the nodelet container fits */ #monkbar, #titlebar-top, #titlebar-bottom, #footer { padding-right: 20 +5px; } /* initial state of all nodelets collapsed */ [id^="nodelet_body_row"] { display: none; }

</update>

    But it does! JavaScript calls them Objects. (Kinda like how objects are usually implemented as hashes in Perl).

    // Hash creation and initialization var hash = new Object; var hash = {}; var hash = { foo: "Foo!", bar: "Bar!" }; var hash = { "spaced out": "ok" }; // Setting hash.foo = "Foo!"; // Static key hash["bar"] = "Bar!"; // Dynamic key // Getting alert("hash.foo: " + hash["foo"]); // Dynamic key alert("hash.bar: " + hash.bar); // Static key // Iterating for (var key in hash) { var val = hash[key]; alert("hash." + key + ": " + val); }
