用大括号替换所有方括号

Question

I have a string "[[[[[]]]]]" and I want to convert it in "{{{{{}}}}}" . I tried "[[[[[]]]]]".replace(/[/g,'{').replace(/]/g,'}') but not luck so far.

Answer 1

The [ square bracket has to be escaped.

 var string = "[[[[[]]]]]"; console.log(string.replace(/\\[/g, '{').replace(/]/g, '}'));

Answer 2

Try this:

var string = '[[[[]]]]';
console.log(string.replace(/\[/g, "{").replace(/\]/g, "}"));
