regex between two special characters

Question

Is there a way to replicate this PHP snippet in JQuery or Javascript...

Answer 1

Is this what you need?

var value = "some {example}";
value.match(/{([^}]+)}/); //array[0] = "{example}" --- array[1] = "example"

Answer 2

Regex are pretty much the same across all languages. If you want to get everything in between {} and put it into an array you can do this:

var arr = [];
var str = 'Lorem {ipsum dolor} sit {amet} conseteur {adipisci}';
str.replace(/{(.+?)}/g, function(a, b){ arr.push(b) });

console.log(arr); //=> ["ipsum dolor", "amet", "adipisci"]

Answer 3

This expression should work fine:

/{([^}]+)}/g

Answer 4

var str = '{Some groovy text}not so groovy text';
var regex = /\{(.*?)\}/;
var value = str.match(regex)[1];  // 'Some groovy text';

This will retrieve the content within the brackets. Hope this helps.

Answer 5

Something like this should do:

 var re = /{[^}]*}/g;
 var s = '{foo},bar,{fum}';

 alert(s.match(re)); // ['{foo}','{fum}']

but you may not want the "{}" included.

var re = /{([^}]*)}/g;
var s = '{foo},bar,{fum}';

var a = [];
var b;
while (b = re.exec(s)) {
  a.push(b[1]);
}

alert(a); // ['foo','fum'];

There's bound to be a way to do it with a single regular expression and no loop.

Answer 6

You can get all blocks of text between { and } into an array with this:

function getBracedText(input) {
    var re = /\{(.*?)\}/g, matches, output = [];
    while (matches = re.exec(input)) {
        output.push(matches[1]);
    }
    return(output);
}

var str = "Some text {tag} and more {text}";
var results = getBracedText(str);
// results == ["tag", "text"];
