Linking Images to Websites in Delphi using TMS Web Core

I am trying to link an image to a website using the TWebImageControl and the TWebLinkLabel components, I am aware that I should use an onClick event however how would the code be written in order for the link to work?

There are two ways to link to websites or open URLs. One is using window.open and the other one is using Application.Navigate.

Application.Navigate

The Application.Navigate function takes two parameters. The first parameter is the URL and the second is the TNavigationTarget.

Navigate to a URL in a new tab:

Application.Navigate('https://www.bing.com', TNavigationTarget.ntBlank);

Navigate to a URL in the same tab:

Application.Navigate('https://www.bing.com', TNavigationTarget.ntPage);

window.open

Here's a little function that I wrote to work with window.open:

procedure OpenURL(URL: String; NewTab: Boolean = True);
begin
  if NewTab then
    window.open(URL, '_blank')
  else
    window.open(URL, '_self');
end;

The NewTab parameter is to specify whether you want to open the link in a new browser tab or in the same tab as your website.

So if you want to navigate to let's say "https://www.bing.com/", then you can write the following code in your onClick event to call the function:

OpenURL('https://www.bing.com', False);

Based on TWebLinkLabel you only need to specify valid URL link as part of its caption and it automatically changes into hyperlink at runtime.

As for TWebImageControl you can specify the URL from which the image is loaded. But of you would like to open a different image when clicking on TImageControl then you would need to use OnClick event and provide a custom URL as it was shown in Shaun Roselt's answer
