Alert Variable

Copy linkTweet thisAlerts:
Jul 13.2003

Hi,

I’ve got two questions:

1) I’m trying to make an alert with the contents of whatever’s in the text box named alert appear when you click a button. Could someone tell me what’s wrong with the button below?

<input type=”button” value=”Preview” name=”Preview” onclick=”alert(“” + form.alert.value + “”);>

2) Is it possible to make a popup window without the titlebar without making it full screen?

Thanks,

Neil

@Khalid_AliJul 13.2003 — change this part of the code

+ form.alert.value +

to this

  • + this.form.alertField.value


    • and make sure your html elements do not have names matching javascript or html keywords that can cause un expected results.

    Second part of your question...full screen mode without title bar only works in IE....in NS base browsers you will never be ale to get rid of titlebar..(as of today ? )

    @CharlesJul 13.2003 — [font=georgia]When you give a form element the name "alert" it overwrites the method with the same name.[/font]

    @neil9999authorJul 13.2003 — I changed the text box's name to 'text' and it works perfectly now.

    Thanks,
