numeric only validation & mouseover

liunx · Jan 9, 2008

Hi All, 
I am trying to ensure that only numeric fields are entered into a text field. Can someone help me out. Here is the code: 
 
if (frmUser.CreditCard.value == "") { 
alert("You must enter a numeric Credit Card number"); 
form.CreditCard.focus() 
return false; } 
 
 
I am also having trouble with the mouseover (Aqua color) effect with this: 
<A HREF = <a class="postlink" href="http://www.htmlforums.com/archive/index.php/">http://www.htmlforums.com/archive/index.php/</a>"chestnut1.asp?prod=Golf Clubs">Golf Clubs</A> 
 
I tried the ALink and VLink. All I want is the text color to change Aqua when the mouse is over it and then it's normal color when the mouse is not on it. I tried a few things but it wouldn't work. 
 
Thanks all!!1) 
 
There is an object in Javascript called Number. 
You can use it like this: 
 
var inp = Number(frMUser.CreditCard.value); 
if (!inp){ 
alert("You must enter a numeric Credit Card number"); 
form.CreditCard.focus() 
return false; 
} 
 
2) 
I suggest you give your link a className: 
<A class="aqua" HREF = <a class="postlink" href="http://www.htmlforums.com/archive/index.php/">http://www.htmlforums.com/archive/index.php/</a>"chestnut1.asp?prod=Golf Clubs">Golf Clubs</A> 
 
And then set up a style sheet in the HEAD of your document: 
<head> 
<style> 
A.aqua: link,visited { color: white; text-decoration: none; } 
A.aqua: hoover {color: aqua; text-decoration: underline; } 
A.aqua: active {color: red; text-decoration: underline; } 
</style> 
</head>
