How do I decode URL special % characters?

Apparently, URL's cannot pass certain symbols, and the URL is ENCODED replacing these symbols

with a Percent sign (%) and as number.

Example:

Text String (URL) received:

data%3Aimage%2Fjpg

Decoded:

data:image/jpg

Question:

Is there a plugin or built in Construct function to DECODE these URL strings?

If not, does anyone know of a way to take an existing string, such as in the above example, and

replace all of the ENCODED characters with the correct symbols?

I am looking for a "Search and Replace" routine, function, or method?

ANSWER: Use the System Expression "RegexReplace" to SEARCH through a string and REPLACE any

characters, or string of characters with another character or string of characters.

Example: RegexReplace(Text.Text, "p", "g", "*")

Searches the string saved in "Text.Text" for the letter "p" and replaces it with "*"

The "g" is s GLOBAL FLAG property that just means to repeat the search and replace thru the

entire string, not just ONCE or the FIRST occurrence.

For my problem with URL special characters, I had to run several operations on the same string.

The % is followed by the ASCII code for the character that was replaced by the browser.

%3A = ":", etc.

RegexReplace(Cookie_IN,"%3A","g",":")

RegexReplace(Cookie_IN,"%2F","g","/")

RegexReplace(Cookie_IN,"%2B","g","+")

RegexReplace(Cookie_IN,"%3D","g","=")

You can use URLencode and URLdecode expressions.

URLDecode("data%3Aimage%2Fjpg") = "data:image/jpg"

Thank you DOP !!

Hey DOP, I am also having trouble with the "Local Storage" in Construct..

I can SET and GET variables ok "within" Construct, however, when I try to GET or SET

those variables "outside" of Construct using standard javascript, I have no success.

I need to save Base64 image data for use by other web pages, not Construct related.

The Base64 data can be large, so Cookies don't work, and passing these values within a

URL doesn't work either. Both cases, the file size exceeds the limits.

I found that I can save these large Bas64 image data strings to Local Storage, thinking I

could access them from another web page using standard javascript, NOT...

Any ideas?
