Question

In javascript I need to get the text within the custom tag. For example

[tag_retweet attr=”val” attr2=”val”]

In this case I need to get the word “retweet” only skipping all other texts and another example is,

[tag_share]

Here I need to get the word “share”.

So what will be the regexp for getting that tag name in my case ??

Answer 1

Something like /\[tag_([a-z0-9_]+)(?:\s+|\])/

var tag = '[tag_retweet attr="val" attr2="val"]';
var match = tag.match(/\[tag_([a-z0-9_]+)(?:\s+|\])/);
window.alert(match[1]);​ // alerts "retweet"
