var sPatternToMatch = /\bsrc="/cachedimages/;
if (sHTMLDetail.match(sPattern) !=null){
...
...
}
gives a syntax error. But if i do something like this

var sPatternToMatch = /\bsrc="cachedimages/; works fine.

I need to do a pattern match for

src="/cachedimages

How can I achieve this?

Please help.

Thank you.

you just need to escape the chars " and / like this:
var sPatternToMatch = /\bsrc=\"\/cachedimages/;
