Browser Drops URL Query Variables

[the_wesley_watkins]

I am trying to use a browser to display an HTML page, and the HTML needs to start with certain URL query variables but the Browser drops everything after the filename.

Code: Select all

URL$ = "index.html?var=6"
BROWSER "n" URL URL$ AT 0,0 SIZE SCREEN_WIDTH(), SCREEN_HEIGHT()

However, when the browser loads up, the "var=6" is dropped from the url.

Code: Select all

PRINT "URL: " & BROWSER_TEXT$("n", document.baseURI)

returns only "index.html"

What can I do!?

[the_wesley_watkins]

I've noticed it's only with local files that this happens.

If you used URL Variables for a website, they are kept. For example,

Code: Select all

URL$ = "http://kibernetik.pro/forum/viewtopic.php?f=26&t=1971" /* this forum */
BROWSER "n" URL URL$ AT 0,0 SIZE SCREEN_WIDTH(), SCREEN_HEIGHT() 

sB actually loads this specific forum. It seems to just not work with local files...

There is no difference between the var=6 in the first post, and the f=26 in your second post.

I've had no issues with dropping of any variables in a URL.

[the_wesley_watkins]

I agree! Other than the fact that in the first example, I am loading a browser with a locally stored html file, and on the other, I am loading a website from the internet. Here's some code to help understand what I'm dealing with:

Code: Select all

URL1$ = "test.html?var=6"
BROWSER 1 URL URL1$ AT 0,500 SIZE SCREEN_WIDTH(), 100
URL2$ = "http://kibernetik.pro/forum/viewtopic.php?f=26&t=1974"
BROWSER 2 URL URL2$ AT 0,650 SIZE SCREEN_WIDTH(), 100


PRINT "URL1$:"
PRINT url1$
PRINT
PRINT "Browser 1 URL:"
PRINT "" & BROWSER_TEXT$("1", "document.baseURI")

PRINT
PRINT

PRINT "URL2$: "
PRINT url2$
PRINT
PRINT "Browser 2 URL:"
PRINT BROWSER_TEXT$("2", "document.baseURI")

And the result is

Notice how even though the URL1$ variable has the URL Variable "var=6", it is dropped when you load it in the browser initially. However, the ones for the link leading to this forum remain...

Wesley,

Here is a program that I use to test URLs, including the execution of CGI Scripts.

I'll look as I haven't run this for a while, but I believe it is all there, and the code is well commented. Ask if you have any questions.

I commented out the "PRINT HTTP Response=R$" statement as that will print the HTML, which in most cases, will exceed the buffer and at the top you will miss the messages.

Also, create a DATA Directory and place the file "HTTPErrorDescription.txt" into it, also attached here, as if you do get an error, it has more detailed info about it.

NOTE: This blog will not allow file extensions with .file or .data, so I changed it to .txt in the attachment and in the code as well. Ignore the comments about this being a .file unless you want to change it back.

Code: Select all

None of this is server side. It's all locally on the iPhone/iPad.

I have an HTML file stored in a "lib" Folder.

I am using it as the URL for a Browser. (i.e. BROWSER "n" URL "lib/index.html?var=6" AT 0,0 SIZE 100,100).

However, what I am saying is the "var = 6" at the end of the URL gets truncated. And this only happens with local HTML files. If you use a link to a website as the URL for the browser, (i.e. BROWSER "n" URL "viewtopic.php?f=26&t=1971" AT 0,0 SIZE 100,100), the URL variables "f=26" and "t=1971" remain.

I know this because when I return the current URL of the browser using BROWSER_TEXT$("n", "document.baseURI"), the browser displaying the local HTML file has dropped the "var = 6", yet the browser displaying the link to a website has kept the "f=26" and "t=1971"

I'm doing all of this on client side, not server side.

[Mr. Kibernetik]

This kind of URL: viewtopic.php?f=26&t=1974 is not a HTML file URL. It is a command to PHP script.

[the_wesley_watkins]

Regardless, I guess my question is just how can I load a local HTML file into a browser and include variables in the URL?

When my application starts, I need to pass a url variable to the url because I have some local client side javascript that uses the variable.

Maybe we have HTML experts here who can comment.
Why do you think it is possible to include variables in the URL?

[the_wesley_watkins]

I already have a program that does this.

Version 1 loads up "index.html" and uses anchor tags to go to other pages (such as <a href="lesson.html?lessonnumber=1">Lesson 1</a>) and it works fine with that, meaning I am able to pull the "lessonnumber=1" out of the URL in my javascript file.

In Version 2, I want to START the program by passing a URL variable to "index.html", such as "index.html?coins=24"

However, when I run

Code: Select all

BROWSER "n" URL "index.html?coins=24" AT 0,0 SIZE 500,500

the "?coins=24" gets truncated(dropped) from the URL. I know this because

Code: Select all

BROWSER_TEXT("n", "document.baseURI")

returns only "index.html".

I need access to the "coins = 24" to start my program properly. I keep it saved locally in a file, and when the user starts up the app, I want to send it in to the HTML.
