Thoughts, ideas, tips, musings, and pontifications (not necessarily in that order) by Ben Forta ...
NOTE: This is my personal blog, and the opinions and statements voiced here are my own.
As per this TechNote, <CFINPUT validate="integer"> allows the dollar symbol ($) to bypass generated client side validation. I don't know how long this has been the case, but the solution (as noted in the TechNote) is to use a regular expression instead.
I have been trying out using the regular expressions to validate and integer entry and find that the regex posted here as well as the one in the tech notes still allows the dollar symbol to bypass.
I too have found that the regular expression method fails, the only client side kludge I have been able to get to work is this... <script> function doCheck(obj){ if(obj.match(/[^\d\.]/)){ alert('numbers only'); document.getElementById('test').value='';} } function ToDollarsAndCents(n) { var s = "" + Math.round(n * 100) / 100 var i = s.indexOf('.') if (i < 0) return s + ".00" var t = s.substring(0,i+1) + s.substring(i+1,i+3) if (i + 2 == s.length) t += "0" return t } </script> <cfinput type="Text" name="amount" range="1,10000" message="You must indicate the amount you wish to submit for this payment" validate="regex" pattern="^((-?[1-9][0-9]*)|0)?$" validateAt="onSubmit" required="Yes" size="5" maxlength="7">
MY Bad, the cfinput tag shown above should be... <cfinput type="Text" name="amount" range="1,10000" message="You must indicate the amount you wish to submit for this payment" required="Yes" size="5" maxlength="7" onkeyup="doCheck(this.value)">
<script>
function doCheck(obj){
if(obj.match(/[^\d\.]/)){
alert('numbers only');
document.getElementById('test').value='';}
}
function ToDollarsAndCents(n) {
var s = "" + Math.round(n * 100) / 100
var i = s.indexOf('.')
if (i < 0) return s + ".00"
var t = s.substring(0,i+1) + s.substring(i+1,i+3)
if (i + 2 == s.length) t += "0"
return t
}
</script>
<cfinput type="Text" name="amount" range="1,10000" message="You must indicate the amount you wish to submit for this payment" validate="regex" pattern="^((-?[1-9][0-9]*)|0)?$" validateAt="onSubmit" required="Yes" size="5" maxlength="7">
