OpenWrt error information #4

Closed angusding closed 7 years ago

angusding commented 7 years ago

I setup wrtbwmon and luci-wrtbwmon in OpenWrt Chaos Calmer and Barrier Breaker. But all of them can't display "Network Usage:". It display the same error in the Chrome and Opera browser.

This page contains the following errors:
error on line 156 at column 43: Specification mandate value for attribute selected
Below is a rendering of the page up to the first error.

That's the contents of the file /tmp/usage.db:

What versions of Chrome/Opera are you using?

I have a "solution" in mind but I want you to test it first to see if that's the actual problem. Are you familiar with the vi command line editor?

angusding commented 7 years ago

Chrome version: 55.0.2883.87 (64-bit) Opera version: 43.0.2442.806 (PGO) I can use vim and edit what your solution need.

Kiougar commented 7 years ago

@angusding OK, try editing the file /usr/lib/lua/luci/view/wrtbwmon.htm. Change the line 10 from:

<option value="5" selected>5 seconds</option>

to

<option value="5" selected="selected">5 seconds</option>

And then try to load the page. Let me know if the error disappears.

angusding commented 7 years ago

The new error information as follows:

This page contains the following errors:
error on line 216 at column 32: StartTag: invalid element name
Below is a rendering of the page up to the first error.

The page "usage" display new information: "Loading..." and "Auto update every" option.

Kiougar commented 7 years ago

Seems like the browser tries to display the page as an XML file. Can you provide a screenshot of what you see when you try to load the page with developer tools open? I want to take a look on the request and response headers.

Kiougar commented 7 years ago

Also, can you please paste here the contents of the /etc/config/uhttpd file?

That's the configuration of BB and CC. They have the same error information.

Kiougar commented 7 years ago

Thanks, can you also provide the Response and Request Headers from the developer tools?

This is how to get them on Chrome:

OK. Can you please try one more edit on the same /usr/lib/lua/luci/view/wrtbwmon.htm file on line 148:

from:

'<td title="' + data[1] + '">' + data[0] + '<br>' + data[2] + '</td>',

to

'<td title="' + data[1] + '">' + data[0] + '<br />' + data[2] + '</td>',

Let me know how it goes.

angusding commented 7 years ago

That's OK. The new error information:

OK, I think I found the issue.

One more edit and it should fix the problem. Please, add this line 

//<![CDATA[

below the <script> tag in line 28. And this line

//]]>

before the </script> tag in line 241.

angusding commented 7 years ago

Kiougar commented 7 years ago

So nothing happens?

Can you open the developer tools again, click the Console tag and take a screenshot after you refresh?

angusding commented 7 years ago

Kiougar commented 7 years ago

Thanks a lot @angusding for the effort!

I have all I need now to create a new version with the fixes.

This issue will be closed when the new version is uploaded.
