When setting an object, I use the following code:
n.name = n.name.join(String.fromCharCode(255));
n.description = n.description.join(String.fromCharCode(255));
After setting the object, I try to alert(n); but it only shows [Object]
Is there a method to display the complete object in the alert?
One feature of Javascript is the ability to add a custom toString() function to objects. This function will be invoked whenever you use alert on the object. Here is an example:
n.toString = function(){
return this.name + '\n' + this.description;
}
Now, when you alert(n); it will show the content specified by your custom function.
Today, I found myself in a situation similar to Autolycus, where I needed to inspect the object created by jqGrid. Despite my reliance on alerts for debugging in JavaScript (I know, old school), I usually turn to FireFox and Firebug. However, today I wanted to see the actual object created by jqGrid that I didn't generate myself.
After exploring a dated resource at , I adapted the code to fit my needs. I believe this modified solution may offer a fresh perspective for Autolycus and others seeking similar insights in the future:
obj = n;
var temp = "";
for (x in obj) {
temp += x + ": " + obj[x] + "\n";
}
alert (temp);
If revisiting an old question violates any guidelines, I apologize in advance.

I have a strong preference for utilizing var_dump in php, which leads me to frequently employ a custom function for dumping variables
function custom_var_dump(object, returnString)
{
var output = '';
for(var item in object)
{
var elem = object[item];
if(typeof elem == 'object')
{
elem = custom_var_dump(object[item], true);
}
output += item + ': ' + elem + '\n';
}
if(output == '')
{
output = 'Empty object';
}
if(returnString === true)
{
return output;
}
alert(output);
}
Consider the following options:
1. Implement blackbirdjs plugin from http://www.gscottolson.com/blackbirdjs/
2. Utilize console.log() available in Firebug, recommended even for IE-focused development to benefit from comprehensive testing in Firefox and Firebug toolset.
When it comes to alerting an entire object, the approach may vary depending on what you intend to achieve.
It's not as simple as converting every object into a string for a meaningful output. The .toString(); method is typically used to specify how an object should be displayed as a string.
For instance, you could try alert(n.toString()); to see if it produces the desired outcome. If the object is custom-made, you can define the toString(); method to return a string containing the specific parameters and fields you wish to display.
Perhaps something along the lines of...
console.log(person.name);
...is what you're looking for.
For debugging purposes, utilizing FireFox with Firebug would be more effective than using multiple alert() statements.
