Regex test() method returning false for a valid regex having match

Question

When pattern is being tested in https://regex101.com/r/YbRw2h/1 , it is displaying two matches.

 var patt = /\\{panel:bgColor=#([A-Fa-f0-9]{6}|[A-Fa-f0-9]{3})}(\\r\\n|\\r|\\n)?(.*?){panel}/gm var str = `{panel:bgColor=#deebff}\\nThis is info panel\\n{panel}fkjfkfwkwfj\\ {panel:bgColor=#deebff}\\nThis is info panel\\n{panel}` console.log(patt.test(str)) //false

How to fix regex?

Answer 1

You probably meant to escape the opening curly bracket at the end. Moreover, you have two line breaks in your string, so you might want to repeat the segment (\\r\\n|\\r|\\n)?(.*?) . Try with the following:

var patt =  /\{panel:bgColor=#([A-Fa-f0-9]{6}|[A-Fa-f0-9]{3})}((\r\n|\r|\n)?(.*?))*?\{panel}/
