javascript - catch SyntaxError and run alternate function
- by ludicco
Hello there,
I'm trying to build something on javascript that I can have an input that can be everything
like string, xml, javascript and (non-javascript string without quotes) as follows:
//strings
eval("'hello I am a string'"); /* note the following proper quote marks */
//xml
eval(<p>Hello I am a XML doc</p>);
//javascript
eval("var hello = 2+2;");
So this first 3 are working well since they are simple javascript native formats
but when I try use this inside javascript
//plain-text without quotes
eval("hello I am a plain text without quotes");
//--SyntaxError: missing ; before statement:--//
Obviously javascript interprets this as syntax error because it thinks its javascript throwing a SyntaxError.
So what I would like to do it to catch this error and perform the adjustment method if this occurs.
I've already tried with try catch but it doesn't work since it keeps returning the Syntax error as soon as it tries to execute the code.
Any help would be much appreciated
Cheers :)
Additional Information: Imagine an external file that javascript would read, using spidermonkey, so it's a non-browser stuff(I can't use HttpRequest, DOM, etc...)..not sure if this matters, but there it is. :)
