Hello,
I am new to javascript and I am working on a web page that has a random number password generator. The random number get generated when you click on the button. But what I would like to do is have the button selected when the page opens putting the random number into the field. Can any one help me with this issue. The button name is "GetNumber" and the field the number is entered into is "YourNumber"

Or can the button be eliminated and the random number is generated when the page is opened?

Thanks

normally when you click a button it calls a function as defined in the onclick handler on the button, something like this:
Code: 
<script type="text/javascript">

function [!]someFunction()[/!] {
   alert("I do something");
}

</script>

<input type="button" value="click me" onclick="[!]someFunction()[/!]" />

if you don't want to wait for the button to be clicked to trigger that function, and instead just have the function execute when the page loads then you would define that in the onload event for the window:
Code: 
<script type="text/javascript">

function [!]someFunction()[/!] {
   alert("I do something");
}

window.onload = [!]someFunction[/!];

</script>

Thank You for the input. But one question. Can the action be triggered without the alert message. I just need it to select the button with no message.

Thanks

Hello,
Since I am new to javascript I am still trying to understad this. So here is what I have done.

<input name="Order_Conformation_Number" type="text" id="Order_Conformation_Number" size=18 />
<input name="button" type="button" onclick="populateform(this.form.thelength.value)" value="Select to Generate Conformation Number" />

so where do I insert the code?

If you are going to use the number as an Order Confirmation number then I would be a little careful to ensure that you don't get duplicates being generated, you may be better if that is the case to use a SEQUENCE or similar functionality in the database to generate the number.

I agree with Greg. If you are generating what is to be a unique number, then use a server-side process to do this. Otherwise two or more customers could get the same confirmation number.

Thank You For the information.
But I used Order Confirmation number and Select to Generate Conformation as an example.
I am just trying to figure out where to insert the
code to select the button when the button when the
page opens.
