SCRIPT1004: Expected ';' error in the browser

Question

I am using this script to hide 'Edit' button from SharePoint ribbon on my custom webpart's ascx page and calling it in the page load:

 function hideEdit() { var edit = document.getElementById("Ribbon.ListForm.Manage,EditItem-Large"); edit.style.display = "none"; alert ("I am an alert box!"); } _spBodyOnLoadFunctionNames.push("hideEdit");

and I am getting two annoying errors:

1)SCRIPT1004: Expected ';'

2)SCRIPT5007: Unable to get property 'style' of undefined or null reference

I have checked like 100 times, there is no semicolon missing. Any clue whats happening here?

how about edit is undefined? maybe because "Ribbon.ListForm.Manage,EditItem-Large" does not look like a valid selector. Please try to learn some JS basics (like debugging). This would have made this mistake obvious. — Mx.

Your problem is really basic and hasnt anything to do with SharePoint. Try to get more knowledge about JS itself and you will find this errors dont appear anymore. — Mx.

Seems like you have entered the selector wrong. THere is never a comma in a selector. Instead of using Javascript, you can achieve this by CSS. You can use the following css to hide the Edit button in the Ribbon.

#Ribbon\.ListItem\.Manage\.EditProperties-Large { display: none !important; }

on SharePoint always try to go CSS before JavaScript css style is applied right away, JavaScript will load and then apply you'll see the blinking (good answer +1) — Mike
