I'm a VB/Notes guy looking for the equivalent of Like and/or @Contains in JS

[mastro78]

I'm working on Input Validation using the JS Header in my Notes app. I originally had formulas in Notes that was doing this, but now I've taken it to the web. So, after redoing the majority of the formulas in JS, I came to one input validation that wasn't within the realm of comparisons in JS. I'm looking that if mystr contains "." then alert, etc. But I can't seem to find anything in JS that is similar. Please advise. Thank you for your help!

hi ...

you may use a regExp for this, like:

var s = 'my.string';
 
var val = /[.]/g.test(s);
 
// now val is true here
 

have a look here for more details. you could even use indexOf();

var s = 'my.string';
 
var val = s.indexOf('.');
 
// val is 2 here ... when there is no . then it would be -1
 

kind regards

thank you
here is what I have

           var dcm = /^.$/
            form = document.forms[0];
            objField = form.QtyLb;
            if( objField.match(dcm)) {
                        objField.focus();
                        alert("Please adjust your weight to whole number.");
                        return false; 
            }

how would I go about plugging in what you offered given the input validation I have?

what do you really want to check? your current regEx matches a single point ... ?

If what is entered has a decimal point. That is what I'm looking to check for.

the regExp:

var re = /[.]/;
 

matches in case there is any decimal-point in the string ... and you should check the value of your field ... not the field itself:

objField.value

kind regards
