Suppose the JavaScript variable is:
var sourceString="stack {overflow} is the best {place} to clear {technical} doubts";
Output javascript string array should contain: overflow,place,technical
or {overflow},{place},{technical}
I am fine with both the results.

You could use regex to accomplish this:
sourceString.match(/{.*?}/g)

var getMatchingGroups = function(s) {
var r=/\{(.*?)\}/g, a=[], m;
while (m = r.exec(s)) {
a.push(m[1]);
}
return a;
};
getMatchingGroups(sourceString) // ["overflow", "place", "technical"]

I'm looking for a regex to test if a url is a root url:
http://site.org TRUE
http://www.example.com TRUE
...
http://www.example.com/dir FALSE
http://www.example.com/image.jpg FALSE
http://www.example.com/dir/file.doc FALSE

Try below regex will do the work
/^https?\:\/\/[^\/]+\/?$/
I tested like this:
var URL = "http://jsfiddle.net/";
var check =/^https?\:\/\/[^\/]+\/?$/.test(URL);
alert(check);
JSFiddle

try this:
var str='url...';
if(str.indexOf("/")<str.indexOf(".")&&(str.indexOf("http://")>-1))
return true;
else
return fals;

Try out with this regular expression
(?\w+)://(?[\w#][\w.:#]+)/?[\w.?=%&=-#/$,]*

I want to have the variable estimatedVal replaced with avgList if estimatedVal is empty. Something is wrong with my code because with the code below nothing happens. If I remove the if statement everything else works:
$('#estimatedVal').html($(context).find('ul.estimates a:eq(1)').text()
+ ' - ' + $(context).find('ul.estimates a:eq(0)').text());
if(estimatedVal == ' - '") {
$('#estimatedVal').html(avgList);
} else {
$('#estimatedVal').html(estimatedVal);
}
What do I need to do to be able to use the if statement?

You've got a "lonely double quote," use an IDE/Code Editor and quit using Notepad :P
if(estimatedVal == ' - ') {
$('#estimatedVal').html(avgList);
} else {
$('#estimatedVal').html(estimatedVal);
}

You've got a stray double quote in your if.
