Maximum string length?

Copy linkTweet thisAlerts:
Aug 17.2006

Does anyone know if there is a maximum string length that can be used in FF and IE browsers? ?

I can display a VERY long string (1200 characters or more) in the alert message, but I don’t know if this is the limit for other javascript commands.

In particular, I would like to know the maximum string length for a
“AnyArray = new Array()” element. 😮

It's pretty quick too, only rendering to a textbox takes ages ( up to 40 seconds )

I am having a problem and wanted to eliminate one possible source.

@konithomimoAug 18.2006 — Unlike languages such as C++, there is no limit to string and/or array lengths in JS. The only limitations are those of the processor.

Even so, it is best to keep the length below 256, since some browsers will have trouble with larger strings.

On another note, when using document.write, you might get an error if your length is greater than 127.

Success!
