[Plugin: WP-Table Reloaded] ‘length’ is null or not an object error

Hi,

that sounds weird.
I can only imagine that there is some JS missing or another one that’s causing a conflict. I have not heard of any such problems with DataTables before.

Can you post the URL to the page with the tables?

Thanks!
Tobias

Hello Tobias.

According my latest observetion the error occures when two different tables co-exist in the same page with different size.
In my opinion the single line table creates the error.

For example:
Table 1;
Horizontal cells 2
Vertical cells 1

Item 1 : price1

Table head: not checked

Table 2;
Horizontal cells 2
Vertical cells 4

item x1 : pricex1
item x2 : pricex2
item x3 : pricex3
item x4 : pricex4

Table head: checked

Thank you.

Hi,

thanks for the details.

I don’t really see why different tables on one page should cause problems.
And actually the DataTables library is not loaded for a table with just one row (because sorting and the other stuff doesn’t make sense then, right?)

Therefore: I’d really need to see the page, so that I can see the JS calling code in the source. Can you please provide a URL? (You can also email it to me, if you don’t want to post it here. My address is in the main plugin file.)

Regards,
Tobias

Hello Tobias.

I do not have a url for WP because I am using a local area network computer where WP is instaled with MySQL for testing purposes. I am testing PHP scripts for cliends ond their request. Usualy I do the troubleshooting for them.

The best way to explain my self why this error occurs it was to give you the above information which I used for my test.
I don’t know why a single raw table creates this error.

Also I have a PC with IE8 and a iMac with Safari.

The error visualy occurs in IE8 on the bottom-left side of the screen and effects the search box, Show entries etc, in which are dessapearing.

On iMac Safari reads the script but it doesn’t run it at all with any kind of tables. I see the tables in the screen, but I cannot see the search box, Next, Previous, Show entries etc.

Thank you again.

Hi,

ok, thanks for the clarification.
If you can not provide a URL, could you maybe email me the HTML source code of the generated page?

Also: I’m about to release a beta version of WP-Table Reloaded 1.6 (there will be an announcement on my website shortly). Could you download that beta version and try it with that?

Thanks!
Tobias

Hello again Tobias.

I use the default theme of WP 2.9 with PHP. I didn’t use any extra html to create a web page. The only thing I add in the WP page was [table id=3 /] [table id=4 /].

I would be glad to help you sending some information, but how I will send HTML code when I do not use it in my test.
Also I would be glad to try your beta version of wp-table reloaded.

Thank you.

Hi,

the beta is now available, so it would be great, if you could test that:
https://tobias.baethge.com/2009/12/beta-test-wp-table-reloaded-1-6/

What I mean with sending me the HTML code is:
Do a right-click into the page with the mouse. There should be an entry like “Show source” in the menu. You will then see the HTML code for the page. Copy that whole piece of code, put it into a new text file and email it to me, please.

Thanks!
Tobias

Hello Tobias.

I download the 1.6 bata version, and the error on IE8 is Gone.
There one thing I do not understand.

When I have 3 tables 2×2, 2×2, 2×1 (single line, two cells) there is a big gap between table 2 and 3. About 6 lines when any other table has 2 lines gap.

The jquery.datatables.min.js script doesn’t work with iMac Safari.
I see the tables but not any other feature compair with IE8.

Thank you again.

Hi,

those gaps are probably margins added by the DataTables script. Can you try turning it off for those tables? (Because I don’t see a real value of sorting/filtering enabled for a 2×2 table). Then the gaps should vanish.

Regarding the iMac Safari. Unfortunately I don’t have a Mac and can’t test the issue ?? Maybe you could ask this in the DataTables forums (https://www.datatables.net) as there are probably more people with Macs.

Regards,
Tobias
