Question

I have a simple javascript variable, filled with a string. Within the string, there are more than 400 double quotes, so to make it valid (or at least, what I thought would be valid), I’ve encased it in single quotes. However, this still seems to return a syntax error, both in my Dreamweaver code console, and using JSLint on my JSFiddle.

Could anyone explain why this produced a syntax error?

It contains unescaped linebreaks.

Either:

• Put everything on one line

• Prefix each line break with \
