[ACCEPTED]-jQuery: print_r() display equivalent?-debugging
console.log
is what I most often use when debugging.
I 1 was able to find this jQuery extension
though.
You could use very easily reflection to list all properties, methods 3 and values.
For Gecko based browsers you 2 can use the .toSource() method:
var data = new Object();
data["firstname"] = "John";
data["lastname"] = "Smith";
data["age"] = 21;
alert(data.toSource()); //Will return "({firstname:"John", lastname:"Smith", age:21})"
But since 1 you use Firebug, why not just use console.log?
How about something like:
<script src='http://code.jquery.com/jquery-latest.js'></script>
function print_r(o){
return JSON.stringify(o,null,'\t').replace(/\n/g,'<br>').replace(/\t/g,' '); }

You can also do
console.log("a = %o, b = %o", a, b);
where a and b are objects.

I've made a jQuery plugin for the equivalent 1 of
<pre>
<?php echo print_r($data) ?>
</pre>
You can download it at https://github.com/tomasvanrijsse/jQuery.dump
$.each(myobject, function(key, element) {
alert('key: ' + key + '\n' + 'value: ' + element);
});
This does the work for me. :)

Top comment has a broken link to the console.log 17 documentation for Firebug, so here is a link to the wiki article about Console. I 16 started using it and am quite satisfied 15 with it as an alternative to PHP's print_r().
Also 14 of note is that Firebug gives you access 13 to returned JSON objects even without you 12 manually logging them:
- In the console you can see the url of the AJAX response.
- Click the triangle to expand the response and see details.
- Click the JSON tab in the details.
- You will see the response data organized with expansion triangles.
This method take a 11 couple more clicks to get at the data but 10 doesn't require any additions in your actual 9 javascript and doesn't shift your focus 8 in Firebug out of the console (using console.log 7 creates a link to the DOM section of firebug, forcing 6 you to click back to console after).
For 5 my money I'd rather click a couple more 4 times when I want to inspect rather than 3 mess around with the log, especially since 2 keeps the console neat by not adding any 1 additional cruft.
