Question

I’m really struggling with the Javascript version of Regular Expression matching, despite knowing how to do it in other languages like C# and PHP.

I wish to match {ANYCHARACTERS}.

It must have:

• a { at the start
• a } at the end
• 1 or more characters between (any characters, symbols etc.)

So far I have the following:

<script type="text/javascript">

// The string that I want to perform a match on
var str = "{ASTRINGINHERE£$%^&*éáó}";

// Mt Matching expression
var patt1 = ^/{(.*){1,*}/}$/i;

// Write the matched result
document.write(str.match(patt1));

</script>

Answer 1

The string start / string end codes belong inside the regex. Also, your repetition code is unnecessarily complex. Finally, there is no need to indicate case independence when you match any character. This should do:

patt1 = /^{.+}$/
