Here the HTML code:
<textarea>I have played arr[0] and i always try to arr[1] in my arr[2]</textarea>
Here is the array:
var arr = ["football", "drive", "city"]
How to replace arr[0], arr[1] and arr[2] with the correct values from the array arr using jQuery on click to create a new textarea with the new content like that:
<textarea>I have played football and i always try to drive in my city</textarea>
Thanks in advance
You could use regex for this:
yourTextArea.value = yourTextArea.value.replace(/arr\[(.+?)\]/g, function (orig, index) {
return arr[index];
})
This captures the index from the "arr[x]" strings, and uses the index to get the data from the arr array. The parentheses define a capturing group, and the .+? does the capturing itself.
It's quick and dirty :)
For reference, I stole the idea from this answer.
By the way you would be better off using an i18n library instead of hacking manually. There are a couple of gettext-like solutions for JavaScript too.

apiratesay arrr not arr :]
$.each(arr,function(i,v) { });
