"Got to here" or a Javascript Debugger written with prototype.js
Maybe I'll use this instead of interspersed lines of
alert('got to here').
// ---------- ---------- ---------- dbgCursorSet
function dbgCursorSet(evt, mouseAction) {
if (mouseAction == 'over') {
evt.element().setStyle({cursor:"pointer"});
}
else if (mouseAction == 'out') {
evt.element().setStyle({cursor:"default"});
}
}
// ---------- ---------- ---------- Debbuger class
var Debugger = Class.create ({
// ---------- ---------- ---------- initialize
initialize: function() {
this.on = 0;
this.msg = '';
this.dbgHeader = '
' +
'Debug ' +
'[resume] ' +
'[pause] ' +
'[clear]';
this.dbgMsgLines = $A();
this.lineTemplate = '#{msg}';
this.tpl = new Template(this.lineTemplate);
this.divMain = document.createElement('div');
Element.extend(this.divMain);
this.divMain.id = "dbgDivMain";
},
// ---------- ---------- ---------- On
On: function() {
this.on = 1;
document.body.appendChild(this.divMain).show();
if ($('dbgPause')) {
$('dbgPause').setStyle({ color: '#333333' });
}

$('dbgResume').setStyle({ color: '#cccccc' });
}
},

Off: function() {
this.on = 0;
if ($('dbgPause')) {
$('dbgPause').setStyle({ color: '#cccccc' });
}
if ($('dbgResume')) {
$('dbgResume').setStyle({ color: '#333333' });
}
},
// ---------- ---------- ---------- Clear
Clear: function() {
this.dbgMsgLines.clear();
this.Write('', true);
},
// ---------- ---------- ---------- Write
Write: function(s, override) {
if (this.on == 1 || override) {
this.msg = s;
this.dbgMsgLines.push(this.tpl.evaluate(this));
var divUpdated = this.dbgHeader;
this.dbgMsgLines.each(function(s) {
divUpdated += s;
})
$('dbgDivMain').update(divUpdated);
$$('.dbgLink').each ( function(ele) {
$(ele).observe ('mouseover', dbgCursorSet.bindAsEventListener(this, 'over'));
$(ele).observe ('mouseout', dbgCursorSet.bindAsEventListener(this, 'out'));
});
if (this.on == 1) {

Where Do I Put the Semi-Colons
All programming can be boiled down to 4 things:
That's why I like the 'Cookbook' style programming books that have simple examples for how to do smallish, specific tasks. In other words, quick examples of where to put the semi-colons.
Maybe that's how I'll use this blog -- as my personal collection of code recipes. Ingredients from my past and current interests include c#, java, perl, c++, prototype.js, and tdd among others.
- assignments
- decisions
- loops
- functions
