Negative Value in Range
I am working with a Coldfusion form and I want to validate a file with a negative and positive range. For example:
Code:
<cfinput range="-90, 90" validate="float" type="text" name="north" maxlength="40" value=""> But this generates the error: Invalid number -90 in range expression! Anyone have any workarounds to this problem?

Try it without a space after the comma between the 2 numbers. But if the range validation that's built in to CF won't take a negative number, then you'll need to write your own Javascript to do the validation.

I ended up having to write my own validation here. You can see the answer below (in Javascript):
Code:
function validateForm () {
for(i=0;i<document.forms[0].elements.length;++i) {
var elem = document.forms[0].elements[i];
if (elem.name == "my_field") {
if((elem.value >= -90) && (elem.value <= 90)) {
}
else {
alert ("Please enter in a value between -90 and 90.");
return false;
}
}
}
myform.submit();
}
Then in the form, I wrote: Code:
<cfform action="get_data.cfm" onSubmit="validateForm(this.form);return false;"> And that seems to work well. Thanks for your help!
