使用正则表达式进行JavaScript匹配

Question

I'm trying to extract some data from a large string and I was wondering if it is possible to use regexp. Currently, I'm using javascript. For example:

This is some [example] text for my javascript [regexp] [lack] of knowledge.

With this string, I would like to generate a JSON array with the texts that are between the square brackets.

example, regexp, lack

I hope someone can help me do this in a simple way so I can understand how it works. Thank you in advance for your help. Daniel!

Answer 1

var str = "This is some [example] text for my javascript [regexp] [lack] of knowledge."
var regex = /\[(.*?)\]/g, result, indices = [];
while ( (result = regex.exec(str)) ) {
    indices.push(result[1]);
}

Answer 2

var text = 'some [example] text for my javascript [regexp] [lack] of knowledge.';
text.match(/\[(.*?)\]/g).map(function(m) {
    return m.substr(1, m.length - 2);
})
// => ["example", "regexp", "lack"]

I wrote one up real quick, if you have any questions about it, let me know!

var a = 'This is some [example] text for my javascript [regexp] [lack] of knowledge.'
var results = a.match(/\[\w*\]/g);

alert(results[0] + ' ' + results[1] + ' ' + results[2]);
