Object Debugger

This is a script that frequently keeps me from using bad words.

It loops through an object and returns its properties in text (for alert) or html format.

Usage:

_viewObj(obj[,instanceName[,type[,levels]]]);

Ex:
var obj = {id:3,arr:[2,3,"str",{prop1:2,prop2:""}],nr:3}

alert(_viewObj(obj));
document.write(_viewObj(obj,"obj","html"));

Parameters:

pValue: The object
pName: Instance name of the object. Default: "input"
pType: Which type to be return (text or html). Default: "text"
pLevels: The max amount of levels. Useful if an object references a parent. Default: infinite

Returns:

A string with the properties

function _viewObj(pValue,pName,pType,pLevels,pObj) {

function objExists(pCurr) {
for (var i=0; i<pObj.length; i++) {
if (pObj[i]==pCurr) {
return true;
}
}
return false;
}


pType = new String(pType).toLowerCase();
if (new String(pName) == "undefined")
pName = "input";
if (new String(pType).search(/html|text/i) == -1)
pType = "text";
if (pLevels == "undefined")
pLevels = -1; /* Infinite */
if (typeof pObj == "undefined")
pObj = [];
var str="";
if (typeof pValue != "function") { // No functions / methods - just values
var br=(pType == "text"? "
" : (pType == "html" ? "<br>" : ""));
if ((typeof pValue == "object" && !!pValue) && (pValue.length) && (!pValue.substring)) { // An array
try {
for (var i=0;i<pValue.length;i++) {
if (pLevels==0) {
str+=br+pName+"["+i+"]: "+pValue;
}else{
str+=""+_viewObj(pValue[ i ],pName+"["+i+"]",pType,pLevels-1,pObj);
}
}
} catch (e) {
str+=br+pName+": "+pValue+" (Not an array)";
}
} else if (typeof pValue == "object" && !!pValue && (!pValue.substring)){ // An object
try {
for (var prop in pValue) {
if (pLevels==0) {
str+=br+pName+"."+prop+": "+pValue;
}else{
if (typeof pValue[prop] == "object" && objExists(pValue[prop])) {
str+=br+pName+"."+prop+": [Parent Object]";
}else{
pObj.push(pValue);
str+=""+_viewObj(pValue[prop],pName+"."+prop,pType,pLevels-1,pObj);
}
}
}
} catch (e) {
str+=br+pName+": "+pValue+" (Not an object)";
}
} else{// if (typeof pValue != "object") { // Simple value
str+=br+pName+": "+pValue;
}
}
return str;
}


edit:

Avoiding never-ending loops by checking for parent objects.

Ex:

var parentObj={id: 2};
var test={id: 1,par: parentObj};
parentObj.tst=test;
