Thread: matching

Where is matchPos1 set?

If you use Firefox, the Error Console gives you more detailed JS error messages.

I have the code like this now

Code:

function calldiscounting()

{



var getdiscount=document.frm1.discount.value;

 

var checkstring=/discounting/;

var matchnow=getdiscount.search(checkstring);

 var matchPos1=getdiscount.search(matchnow);

if(matchPos1 !=-1)

{

                                alert("discount good");

}

else

{

              

}

 

 

 

}

I would have thought this would work:-

Code:

function calldiscounting()

{

var getdiscount=document.frm1.discount.value;

var checkstring=/discounting/;

var matchPos1=getdiscount.search(checkstring.toLowerCase());

if(matchPos1 !=-1)
{
    alert("discount good");
}
else
{
}

}

The search method should return either a value or -1 if it doesn't find the string. I'm not sure of the relevance of the additional search method you call using matchnow.

Or you can use a modifier on the RegEx to perform case insensitive matching:

Code:

var getdiscount=document.frm1.discount.value;
var checkstring=/discounting/i;
var matchPos1=getdiscount.search(checkstring);

And @RR, I think you mean:

Code:

var matchPos1 = getdiscount.toLowerCase().search(checkstring);

Yep. That is what I meant...
