Hi,

Can I ask what is the fastest way in AS3 to change an array from var array1 = [1, 2, 3, 4, 5]
to var array1 = [1&2&3&4&5]

I would think it would be array1.join(”&”) but having trouble.
thanks for any help.

Just to add - (perhaps you could merge the two comments?) - the above code used to work well, but it is just so satisfying to find a one line solution to replace it. Thank you!

Just a quick word of thanks - I’ve been looking for a ‘quick’ solution for about the past hour. This brilliantly simple solution is exactly what I needed.

Finally, no messing about with code like:

String.prototype.replace = function()
{
var arg_search, arg_replace, position;
var endText, preText, newText;
arg_search = arguments[0];
arg_replace = arguments[1];
if(arg_search.length==1) return this.split(arg_search).join(arg_replace);
position = this.indexOf(arg_search);
if(position == -1) return this;
endText = this;
do
{
position = endText.indexOf(arg_search);
preText = endText.substring(0, position)
endText = endText.substring(position + arg_search.length)
newText += preText + arg_replace;
} while(endText.indexOf(arg_search) != -1)
newText += endText;
return newText;

}

Brilliant - thank you!

There is a way to check strings using regular expressions too I believe. For example, if you need to check if the first 5 characters in a string are “hello” for example:

var myString:String = “hello there”;
var parts:Array = myString.match(/[a-z]{5}/g);
trace(parts[0]) // hello
