Need to force only numbers in the. Help

[thelke]

How can I force this phone number format field to only accept numbers?

Thank you.

var n;
var p;
var p1;
function ValidatePhone()
{

p=p1.value
if(p.length==3)
{
pp=p;
d4=p.indexOf('(')
d5=p.indexOf(')')
if(d4==-1)
{
pp="("+pp;
}
if(d5==-1)
{
pp=pp+&quot";
}
document.frmOlyrepro.Phone.value="";
document.frmOlyrepro.Phone.value=pp;
}
if(p.length>3)
{
d1=p.indexOf('(')
d2=p.indexOf(')')
if (d2==-1)
{
l30=p.length;
p30=p.substring(0,4);
p30=p30+&quot"
p31=p.substring(4,l30);
pp=p30+p31;
document.frmOlyrepro.Phone.value="";
document.frmOlyrepro.Phone.value=pp;
}
}
if(p.length>5)
{
p11=p.substring(d1+1,d2);
if(p11.length>3)
{
p12=p11;
l12=p12.length;
l15=p.length
p13=p11.substring(0,3);
p14=p11.substring(3,l12);
p15=p.substring(d2+1,l15);
document.frmOlyrepro.Phone.value="";
pp="("+p13+&quot"+p14+p15;
document.frmOlyrepro.Phone.value=pp;
}
l16=p.length;
p16=p.substring(d2+1,l16);
l17=p16.length;
if(l17>3&&p16.indexOf('-')==-1)
{
p17=p.substring(d2+1,d2+4);
p18=p.substring(d2+4,l16);
p19=p.substring(0,d2+1);
pp=p19+p17+"-"+p18;
document.frmOlyrepro.Phone.value="";
document.frmOlyrepro.Phone.value=pp;
}
}
setTimeout(ValidatePhone,100)
}
function getPhone(m)
{
n=m.name;
p1=m
ValidatePhone()
}
function testphone(obj1)
{
p=obj1.value
p=p.replace("(","&quot
p=p.replace(&quot","&quot
p=p.replace("-","&quot
p=p.replace("-","&quot
if (isNaN(p)==true)
{
alert("Check phone"
return false;
}
}

Use this function:

function validInput(val,evt) {
var e=new Object();
e.which=(evt)?evt.which:event.keyCode;
return (e.which>=48||e.which<=57);
}

In conjuction with this onkeydown event handler:

onkeydown=&quot;return validInput(this.value,event);&quot;

Hope that helps!

Happy coding!

is there a way I can put the code into this current function? I would not know how call 2 different functions on the same text box. New the javascript. Thank you

hi thelke,

your testphone() function will work with slight modification:

function testphone(obj1) {
	p=obj1.value

	for (idx = 0; idx < p.length; idx++) {
		p=p.replace(&quot;(&quot;,&quot;&quot;)
		p=p.replace(&quot;)&quot;,&quot;&quot;)
		p=p.replace(&quot;-&quot;,&quot;&quot;)
		p=p.replace(&quot;-&quot;,&quot;&quot;)
	}
	
	if (isNaN(p)) {
		alert(&quot;Numbers only please.&quot;);
		return false;
	}
}

======================================

if (!succeed) try();

that did not work.

not sure

 

[thelke]

that did not work.

not sure why, I replaced the other code. Am I doing something wrong?

I am pulling the code this way:
<input type=&quot;text&quot; size=&quot;15&quot; name=&quot;Phone&quot; onFocus=&quot;javascript:getPhone(this)&quot; maxLength=&quot;13&quot;>

and I am referencing the javascript thru a .js file

Get rid of the javascript: tag in the onFocus event handler:

<input type=&quot;text&quot; size=&quot;15&quot; name=&quot;Phone&quot; onFocus=&quot;getPhone(this)&quot; maxLength=&quot;13&quot;>

I like jemminger's function, and use something similar to it for this kind of thing myself that's just a matter of style:

function testphone(onenumber)
{
var pnum=onenumber.value;

while (pnum.indexOf('(') > -1) pnum=pnum.replace('(','');
while (pnum.indexOf(')') > -1) pnum=pnum.replace(')','');
while (pnum.indexOf('-') > -1) pnum=pnum.replace('-','');

if (isNaN(pnum))
{
alert(&quot;Numbers only please.&quot;
return false;
}
return true;
}

I figured out what is getting me. You are giving me code to validat that only numberrs are in the field. I have a format script on the field. But the format field does not call the validation function, and I do not know how to call it. I am new to javascript. Here is the code to format the field.

var n;
var p;
var p1;
function ValidatePhone()
{
p=p1.value
if(p.length==3)
//d10=p.indexOf('(')
{
pp=p;
d4=p.indexOf('(')
d5=p.indexOf(')')
if(d4==-1)
{
pp=&quot;(&quot;+pp;
}
if(d5==-1)
{
pp=pp+&quot&quot;;
}
//pp=&quot;(&quot;+pp+&quot&quot;;
document.frmOlyrepro.Phone.value=&quot;&quot;;
document.frmOlyrepro.Phone.value=pp;
}
if(p.length>3)
{
d1=p.indexOf('(')
d2=p.indexOf(')')
if (d2==-1)
{
l30=p.length;
p30=p.substring(0,4);
//alert(p30);
p30=p30+&quot&quot;
p31=p.substring(4,l30);
pp=p30+p31;
//alert(p31);
document.frmOlyrepro.Phone.value=&quot;&quot;;
document.frmOlyrepro.Phone.value=pp;
}
}
if(p.length>5)
{
p11=p.substring(d1+1,d2);
if(p11.length>3)
{
p12=p11;
l12=p12.length;
l15=p.length
//l12=l12-3
p13=p11.substring(0,3);
p14=p11.substring(3,l12);
p15=p.substring(d2+1,l15);
document.frmOlyrepro.Phone.value=&quot;&quot;;
pp=&quot;(&quot;+p13+&quot&quot;+p14+p15;
document.frmOlyrepro.Phone.value=pp;
//obj1.value=&quot;&quot;;
//obj1.value=pp;
}
l16=p.length;
p16=p.substring(d2+1,l16);
l17=p16.length;
if(l17>3&&p16.indexOf('-')==-1)
{
p17=p.substring(d2+1,d2+4);
p18=p.substring(d2+4,l16);
p19=p.substring(0,d2+1);
//alert(p19);
pp=p19+p17+&quot;-&quot;+p18;
document.frmOlyrepro.Phone.value=&quot;&quot;;
document.frmOlyrepro.Phone.value=pp;
//obj1.value=&quot;&quot;;
//obj1.value=pp;
}
}
//}
setTimeout(ValidatePhone,100)
}
function getPhone(m)
{
n=m.name;
//p1=document.forms[0].elements[n]
p1=m
ValidatePhone()
}

The getPhone() function is called in the ASP this way

<input type=&quot;text&quot; size=&quot;15&quot; name=&quot;Phone&quot; onFocus=&quot;getPhone(this)&quot; maxLength=&quot;13&quot;>

How do I use any of these validation functions with the format function?
