Converting strings to numbers in JavaScript

Try 123abc in any one textbox and press add..
and plz give the solution

Dear Venkat, Thanks for your clear and understandable articles on .Net Technologies, I request you to please post videos on CSS.

Hi Venkat, Thanks for the tutorial. I typed the code in notepad, notepad++ and in Dreamweaver but when I saw the html page in browser it is showing, one table with border and names of the text fields alone. Text fields are not displayed. Why?, will you please help.

Thanks venkat

I love your examples because they solve real world problems !

Thank you very much for this video.

this man is the truth! shout out to all my Indians out there!

what about when we want both int as well as float

Just out of curiosity (I'm new to JavaScript) why wouldn't you use input type="number" instead of input type="text"?

i did it like this...

html --------------------------------

<input id="firstNumber" placeholder="0" /><br />
<input id="secondNumber" placeholder="0" /><br />
<button onclick="myNumber()">Add</button>
<p id="showNumber"></p>

-----------------end of html--------------------

java script ----------------------------------

function myNumber() {
var x, y, display;
display = document.getElementById("showNumber");
x = Number(document.getElementById('firstNumber').value);
y = Number(document.getElementById("secondNumber").value);
display.innerHTML = x + y;
if(isNaN(x) && isNaN(y)) {
display.innerHTML = "input numbers";
return;
}
if(isNaN(x)) {
display.innerHTML = "first box is not a number";
return;
}
if(isNaN(y)) {
display.innerHTML = "second box is not a number";
return;
}
}

-----------------------end of js-------------------------

umm is it good?

Thank you for the tutorial but IsNan methond not working

in tutorial number 7 you mentioned , we should not place the script file into head tag , but in this example you put the function "addNumber" in head tag. I am kinda confuse .
