Hi Saman,
Now this is an odd request
Are there images in the html page? Is there javascript in the page?
I'm trying to guess why you'd want a webpage as an image... Here lets waste some time together; In Windows you do a prtSc of your browser and save it as an image.

HoHum, do I go on?

Hello Simon,

maybe i'm made a wrong explanation about the browser function.
actually what i want is how to disable a link in browser object (image area).

nice to meet you Simon.

Hi Saman,
Is "on browserBeforeNavigate" what you are looking for?
If you know the URL (or part of it) then you can block it.

Simon,
it's my first time learning about internet related stuff with livecode,
hope you can give detail example "on browserBeforeNavigate".

Kind regard's

if you look in the dictionary under browserbeforenavigate, you can see that its does what it says. The message fires before the navigation actually occurs.

Near the bottom of the dictionary entry it says this: "To prevent the navigatation from occurring, set the global variable browserCancel to true."

so, to stop navigation from happening something like this should work..
You could always check the URL of course to see if you actually want to cancel or not.

Code: Select all

on browserbeforenavigate pInstance,pUrl
global browserCancel -- define the scope.. I think this is necessary.  
put true into browserCancel -- sets the variable to true so LC knows to cancel the navigation.

end browserbeforenavigate

You could always check the URL of course to see if you actually want to cancel or not.

So sorry but i still can not understand it clearly (((

If a user clicks on a link, before the navigation to the new URL is done, the message "browserbeforenavigate" is sent.


Say you have a page with 3 links on it. And you only want one of the links to actually do something..
If your links are:
htp://www.myurl.com/link1
htp://www.myurl.com/link2
htp://www.myurl.com/link3

And you only want link2 to work you can set things up like this..

With great power comes great responsibility.

There may be many good reasons to alter the behavior of links from pages hosted on your own site, but altering the behavior of links from sites owned by others can be viewed as hijacking that link.

For example, we could open a page with a link to the user's bank, and then route the request to a page we've designed to spoof the bank to obtain the user's login credentials.

If the user discovers any form of link hijacking on their own (any differences in behavior between how a page reacts to links in your browser vs. any other browser), in these security-conscious times they may become suspicious of all URL handling within your app. Given the speed with which things flow through social media, any minor mistake can quickly become a PR nightmare.

Tread carefully.....
