text.replace()

[scottybwoy]

Why would text.replace give an error that it is not a function and halt the script?

 

Here is how it is evoked:

 

if (/^[\],:{}\s]*$/.test(text.replace(/\\./g, '@').
replace(/"[^"\\\n\r]*""|true|false|null|-?\d+(?:\.\d*)?(:?[eE][+\-]?\d+)?/g, ']').
replace(/(?:^|:|,)(?:\s*\[)+/g, ''))) {

}

 

Thanks

I'm fairly new to javascript as I'm more a php guy, but shouldn't you need a ' around the ereg?

if (/^[\],:{}\s]*$/.test(text.replace('/\\./g', '@').

replace('/\\./g', '@')

 

Just a thought.

Thanks, it was not a problem with the code.  I just used that one as an example.  What I wanted to know is why that error comes up sometimes.  I have seen it with a few functions, but also new to Java, (more a php person) just wanted to know why.

sorry I can't help you their. I've only just started working with javascript last night.. so you probably know more than me

the syntax throws me off a bit. I keep doing silly things like:

toUpperCase(somevar);

instead of:

somevar.toUpperCase();

 

Which does throw up a non-function error. Maybe that's what's happening.. You're just setting it wrong sometimes.

first im not sure if u can do replace like that, i dunno for a fact since i havent been coding js for long.

also try using var's instead of the long strings in the if.

 

this could be wrong, im just using what ive learned so far:P.

exp = '/^[\],:{}\s]*$/';
x = text.replace(/\\./g, '@');
x = x.replace(/"[^"\\\n\r]*""|true|false|null|-?\d+(?:\.\d*)?(:?[eE][+\-]?\d+)?/g, ']');
x = x.replace(/(?:^|:|,)(?:\s*\[)+/g, '');

if (exp.test(x)) {

}
