Uncaught Typeerror cannot read property

Question

I have been working with on project. It was working at first but now I get a error when I moved it to a server that we have. I have been working with html and php. Here is the error "(index):26 Uncaught TypeError: Cannot read property 'innerText' of null at saveTable ((index):26) at HTMLButtonElement.onclick ((index):21)" This is from google chrome. And here is line 26 and 21:

Line 21

<button type="button" onclick="saveTable();">Spara</button>

Line 26

xhttp.open("GET", "backend.php?action=save&Adress=" + document.getElementById("Adress").innerText + "&Fastighet=" + document.getElementById("Fastighet").innerText + "&Kostnadsstalle=" + document.getElementById("kostnadsstalle").innerText + "&Fabrikat=" + document.getElementById("Fabrikat").innerText + "&Typ=" + document.getElementById("Typ").innerText + "&Model=" + document.getElementById("Model").innerText, true);

could you please post all your HTML code? – CapitanFindus Mar 03 '18 at 16:32 — CapitanFindus, Mar 03 '18 at 16:32

Difference between innerText and innerHTML. This might help. innertext is not supported in some browsers like Mozilla. As for Google Chrome, I'm not sure but I advice you check this link.

Don't think that's the problem. It worked before on google chrome. But when I put it on the server this happend. – JocularMarrow Mar 03 '18 at 17:55
It might be a spelling error. I mean is the id "Adress" or "Address". – user9418148 Mar 03 '18 at 18:03
And line 26 is too long. Try to split it into multiple lines. – user9418148 Mar 03 '18 at 18:05
No spelling errors it's just Swedish :). Will try to split it – JocularMarrow Mar 03 '18 at 18:48
Adress has no id. Give it an ID of "Adress". – user9418148 Mar 03 '18 at 18:53
Give all of them IDs – user9418148 Mar 03 '18 at 18:53
Check line 38 that's the IDs – JocularMarrow Mar 03 '18 at 19:01
Think I narrowed one of the errors down to this line – JocularMarrow Mar 03 '18 at 19:04
"&Kostnadsstalle=" +document.getElementById("kostnadsstalle").innerText – JocularMarrow Mar 03 '18 at 19:04
*Check line 38 that's the IDs* You gave them IDs in line 38 and was trying to use their ID in line 26. That's the problem. – user9418148 Mar 03 '18 at 19:31

Should I move up line 38 above 26? Then I don't understand how it worked before. I have just added some more table content and moved it over to a server that I have. – JocularMarrow Mar 03 '18 at 19:37

Give the table headers an id before using it.

Edit: Oh. Well. Just saw it now. I don't think this is the reason at all. The function loadTableContents() is called before saveTable(). So I think your code is perfectly alright. And since you said it worked before the problem is with your server

First I was thinking that the server was missing php, and it did. So I fixed that. But that didn't help. After 12 hours of trying to find the solution without progress I had to give it a try here. So can you recommend me where to start? – JocularMarrow Mar 03 '18 at 20:04
The problem might be in the php file. I will add it on my post – JocularMarrow Mar 03 '18 at 20:05
I have no idea. – user9418148 Mar 03 '18 at 20:44
