The code above worked in Internet Explorer (v8) and Firefox (v3.5). They both DID let me download.
I don't know why it's not working in your case. What browser are you using?

I don;t think you can do that directly with javascript - unless you put the file contents in a textarea - as js does not have access to files outside of the browser - so you may as well do it with a server side language (PHP/ASP)

You can use Regular Expressions.

Example:

<script type="text/javascript">
var source; //Assign Your Text File's content
var re=new RegExp(/File([^\^]*?)EndFile/g); //Pattern to match
var matches=source.match(re); //Search for matches and assign them to 'matches'
if (matches!=null)//if any match found
{
  for (i=0;i<matches.length;i++){
    //'matches' is the array that contains all the matches found
    //you can do whatever you want with them, in this case we'll just
    //display messageboxes containing the match.
    alert("Match #"+i+" is "+matches[i]);
  }
}
</script>

Hope that helps.

So you need to apply a filter to the content of combobox2. Without knowing anything about how it is populated or even what language you are using thats all I can tell you.

Javascript: url in html

Re: Javascript: url in html

Hi
I have a URL in html format.
For example:
http://wutever.com/

And I want to convert it to:
http://wutever.com/

How can I do that?
Is there any function like encodeURI() ?

Any help would be greatly appreciated.

Transfer JavaScript Array between pages

Joshua Henderson18-Aug-09 17:16

18-Aug-09 17:16

Hi,

I am looking for an easy way to transfer a javascript array from one page to another. The page that it is being transferred to will be either POSTed or GETted (hmm, that didn't quite work how I wanted it to) from the previous page.

One way that I have thought of is converting it to a string and sending it over GET, and I found this[^], but I have a few concerns with it. It is firstly a two dimensional array, so I would need to convert that to a string and then convert it back at the other end, the second is security (if it is sent over GET, even on an SSL connection, URL will probably still be visible to someone eves dropping), and third is length (the string could get very long very quickly, and there could become problems if the URL gets too long and messy). That said, I could also devise a way using a hidden form object to send it over POST, so I would probably end up doing it that way.

My question is basically, should I convert it to a string and then parse it back into an array later on, or is there an easier way that I am missing?

Thanks heaps, Josh.

if security is an issue you can use encryption to encrypt the array. you could look into using AJAX post as well. jQuery is an excellent extension for helping with this and great for beginnners (those who havent delt with creating httprequests before).

I know in PHP you can serialize the array - so maybe there's an equivalent function in javascript?

Re: Transfer JavaScript Array between pages

Thanks for the reply.

What I am doing as a solution is turning the array into one long string, using AJAX to store it in a PHP session, moving to another page and then having PHP process it when it restores the session.

Basically, the code I am using to turn the array into a string is:

function convertTwoDimensionArrayToString(arrayToConvert) {
	arrayAsString = "7"
	for (i in arrayToConvert) {
		for (j in arrayToConvert[i]) {
			arrayAsString += "%%" + arrayToConvert[i][j];
		}
	}
	return arrayAsString;
}

Because it is a two dimensional array, I need to run the for loop twice, but that said, it will put everything into one long, string (obviously). To turn it back into a two dimensional array, I have used the first index (0) to define the array length so the second dimension in every array in this case has a length of 7. I don't know if I explained my logic that well, but it makes sense to me Wink | ;)

This will ONLY work if the second dimension in the array is always the same length (and in my case, it ALWAYS will be, there would be a major flaw in the program if there wasn't). If the second dimension in the array varies in length, I would change the code to separate the different index's of the second array differently to how I would separate the different index's of the first array.

It definitely does work (and it gives me a way to get the array from javascript to php without too problems as well!), but it isn't the most elegant solution. Just thought I would share my solution with others!

Re: Transfer JavaScript Array between pages

Marc Firth20-Aug-09 2:47

You could send the items of data individually using AJAX if, for example, it is entered into a form and have PHP convert it into the array.

Also, if the amount of data is too long you could encrypt it and store it as an encrypted cookie - so long as it doesn't affect usability if the cookie is deleted (You can pass cookies between javascript and PHP).

Depends on you definition of "elegant solution", development speed or short fancy code. Your code looks fine to me anyway. Clean, readable and concise.
