Discussion Overview

The discussion revolves around troubleshooting issues with LaTeX popups in the Opera browser, specifically regarding missing images and source code visibility. Participants are examining the technical aspects of how LaTeX is rendered and displayed in different browsers.

Discussion Character

  • Technical explanation, Debate/contested

Main Points Raised

  • One participant reports that certain LaTeX images do not display their source when clicked in Opera 7.54, providing specific examples from a forum thread.
  • Another participant suggests that the issue may be related to the handling of single quotes in the JavaScript code, proposing a potential fix by escaping single quotes.
  • A third participant acknowledges the issue and expresses willingness to investigate further.
  • A different participant notes that similar problems occur in Firefox 1.0, indicating that the issue may not be limited to Opera.

Areas of Agreement / Disagreement

Participants have not reached a consensus on the cause of the issue, and multiple viewpoints regarding potential fixes and the scope of the problem remain. The discussion is ongoing.

Contextual Notes

The discussion highlights potential limitations in the JavaScript implementation for rendering LaTeX, particularly concerning character handling, but does not resolve the underlying technical issues.

The source doesn't pop up when I click on certain LaTeX images.

I'm using Opera 7.54

Here are some examples:

https://www.physicsforums.com/showthread.php?t=65125

On post #1, I cannot see the source of the second image. (BUt I see the others)

On post #10, I can't see the first, fourth, fifth, or sixth image. (Out of 6)

Here is my attempt at reproducing some of those I can't see in post #10:

[itex]E = E' f_{\lambda}[/itex]
[tex]( \mathbf{\nabla \cdot E'} f_{\lambda} ) + \frac{V}{\lambda^2} = \frac{\rho}{\epsilon_0}[/tex]

Lo and behold, I cannot see the source of these.

Looking at the source code it seems like the single quote is the culprite. The javascript is interpreting it as the end of the argument. This should be a simple fix. Just print it out as \' whenever it comes up inside the tex code.

If it matters, they don't work in Firefox 1.0 either.
