When I include only the jQuery 1.4 Library, I get an exception, why?
I keep getting this error all over the place where I only have jquery 1.3 or 1.4 included.
"setting a property that has onl开发者_运维百科y a getter"
and a long list of warnings in the Firefox Error Console.
What's going on? I can't find any information on this issue =/

Do you have a "use strict";
statement anywhere? That causes ECMAScript5 browsers to parse JavaScript a little different and could cause this to be returned as an error.
You can remove this to fix the error, but that means you don't benefit from use strict
. Note that use strict
works in whatever scope it is executed in. So, if you want to load jQuery as non-strict, but have the rest of your code be strict, you can do this:
//load jQuery here
//create a scope
(function() {
"use strict";
// your code here
})();
Although this question has already been answered, I felt this was necessary.
OP probably has strict warnings turned on in his about:config in Firefox.
To change this just load up about:config
in Firefox then scroll down to javascript.options.strict
and then change this value to "false"
.
