1306029 - Unable to show inline JS source in data URI document

Status: RESOLVED WORKSFORME

(DevTools :: Debugger, defect, P3)

Description

[Andreas Tolfsen ❲:ato❳]

When putting an inline script inside a data URI, devtools is unable to show the source in the ‘Source’ pane in the ‘Debugger’ tab.

A sample URI is data:text/html;charset=utf-8,%3Cscript%3E%0D%0Aconsole.log("first line")%3B%0D%0Aconsole.log("second line")%3B%0D%0A%3C%2Fscript%3E, which contains to lines of JavaScript:

    <script>
    console.log("first line");
    console.log("second line");
    </script>

Interestingly, if you add a `debugger` statement in there, it _will_ stop and show you the source:

    <script>
    console.log("first line");
    debugger;
    console.log("second line");
    </script>

Data URI of last example:

data:text/html;charset=utf-8,%3Cscript%3E%0D%0Aconsole.log("first line")%3B%0D%0Adebugger%3B%0D%0Aconsole.log("second line")%3B%0D%0A%3C%2Fscript%3E

I recommend using http://software.hixie.ch/utilities/cgi/data/data when working on this.

I do see the script, but it shows up in the page's markup as a source.  This is the same behavior for when a script tag is embedded in an html page.  This might be feature request to make inline script tags get listed as separate scripts in the sources list, but I don't think that's specific to data URIs

What I see when I open data:text/html,<script>console.log("first line");console.log("second line");</script> in a tab.  Note the UI is different with the new debugger frontend but it's the same basic thing.

Honza, could you verify?

Since it isn't related to data URIs and I can see the script source in the Sources tree, I am closing the report.
Feel free to file a feature request for improving the Sources tree structure.
