I'm using var numbersInString = input.match(/\d+/g); to put into an array the first 2 digital numbers.
Such as: Is 6 greater than 5?
Note: (A person types this into an input box and the answer is displayed in a similar input box. So I must keep this in a similar format. The "if statement" below checks the input. If the information I need is not present it simply doesn't trigger and is answered with a "I Dunno" type of response later in the script.
numbersInString[0] - will give the first number
numbersInString[1] - will give the second number
I then want to compare the numbers as either > < or =
I can't seem to get any combinations that works and I don't understand why.
I can add/substract the 2 numbers and get a correct answer. I can't seem to get a valid > < type of answer though
This is part of a bigger script of "If like statements" so I am not looking for a complete rewrite. I'm hoping I am just missing something in the below that is causing me problems.
Thanks
Code:
if ((input.search("what is greater")!= -1) && (input.search(/\d{1,10}/)!=-1) && (input.search(/\d{1,10}/)!=-1))
{var numbersInString = input.match(/\d+/g);
var num1 = parseInt( numbersInString[0], 10 );
var num2 = parseInt( numbersInString[1], 10 );
if (num1 < num2) document.result.result.value = ""+num1+" is less than "+num2+"";
if (num1 > num2) document.result.result.value = ""+num1+" is greater than "+num2+"";
if (num1 = num2) document.result.result.value = "Both numbers are equal";
return true;}
<script type="text/javascript">
function compareNums(num1,num2) {
var result = "I don't know. ";
var n1 = parseInt(num1); if (isNaN(n1)) { result += num1+" is not a number. "; return result }
var n2 = parseInt(num2); if (isNaN(n2)) { result += num2+" is not a number. "; return result }
if (n1 < n2) { result = n1+' is less than '+n2; }
else {
if (n1 > n2) { result = n1+' is greater than '+n2; }
else { result = n1+' is equal to '+n2; }
}
return result;
}
// 3 valid entries
alert(compareNums(1,2));
alert(compareNums(2,2));
alert(compareNums(3,2));
// 3 goofy entries
alert(compareNums('a',2));
alert(compareNums(1,'b'));
alert(compareNums('a','b'));
</script>
Sorry, I'm not following the code. As a mentioned the present "if statement" screens out all the unnecessary information. I don't need any bailout responses in regards to this "if statement". If 2 seperate digital numbers aren't present it just doesn't trigger nor do I want it to at this point.
So with that said I don't know what to pull out or add to my present code. Something like this perhaps?
if ((input.search("what is greater")!= -1) && (input.search(/\d{1,10}/)!=-1) && (input.search(/\d{1,10}/)!=-1))
{var numbersInString = input.match(/\d+/g);
var result = "I don't know. ";
var n1 = parseInt(num1);
var n2 = parseInt(num2);
if (n1 < n2) { result = n1+' is less than '+n2; }
else {
if (n1 > n2) { result = n1+' is greater than '+n2; }
else { result = n1+' is equal to '+n2; }
}
return result;
Here is the demo I'm testing it on.
Code:
<HTML>
<HEAD>
<TITLE>ChatterBot Page</TITLE>
<script language="JavaScript">
var message = new Array();
var randomnum;
var flagrandom;
function Parse() {
var input = new String(document.chat.input.value);
document.chat.input.value="";
input=input.toLowerCase();
word=input.split(" ");
num_of_words=word.length;
input=input.replace(/[!|?|,|.]/g,"");
word=input.split(" ");
if (input.search(/\bu\b/)!=-1) input=input.replace(/\bu\b/,"you");
if (input.search(/\br\b/)!=-1) input=input.replace(/\br\b/,"are");
if (input.search(/\bk\b/)!=-1) input=input.replace(/\bk\b/,"ok");
if (input.search(/\by\b/)!=-1) input=input.replace(/\by\b/,"why");
if (input.search("ok")!= -1)
{document.result.result.value = "Okay, that's interesting.";
return true;}
if (input.search("yes")!= -1)
{document.result.result.value = "Okay, yes it is.";
return true;}
if (input.search("no")!= -1)
{document.result.result.value = "Okay, no it is.";
return true;}
if (!flagrandom) {
randomnum = [Math.floor(Math.random()*3)]
flagrandom=true;}
message[0] = "Sorry, you stumped me on that one.";
message[1] = "Sorry, a search of my data base comes up empty.";
message[2] = "Not sure";
document.result.result.value = message[randomnum];
randomnum++
if (randomnum>2){randomnum=0}
return true;}
