Javascript remove substring

Question

I have a string of the following format:

[text text] Text to stay

And I want to remove the brackets and the text inside, so that the final string will be:

Text to Stay

Is it possible to achieve this using regex and the function replace?

Yes, you can do it with replace function and regexp, as follow:

var text = "[text text] Text to stay";
var replaced = text.replace(/\[(.*)\]/, "");

Check this snippet:

var text = "[text text] Text to stay";
var replaced = text.replace(/\[(.*)\]/, "");

document.write(replaced);

That would turn **`"[text text] Text to ] stay"`** into just **`" stay"`**. You should use a non-greedy matching instead. – Anders Marzi Tornblad Jan 12 '17 at 13:54

var str = "[text text] Text to stay";
alert(str.replace(str.substr(str.indexOf('['),str.indexOf(']') - str.indexOf('[') + 1),""));

You can try this short hand.

var text = "[text text] Text to stay";
var updatedText = text.split('] ')[1];

This regex also works when the text includes ].

var text = "[text text] Text to stay";
var replaced = text.replace(/\[.*?\] /, "");

document.write(replaced);
