controlling length of string from prompt

[kristinac13]

Is there a way to control the length of the string a user enters into a prompt window? I have an asp, html, java filled web app and at one point the user receives a prompt and must enter a string. If the string is longer than the width of the prompt window, altho the prompt window allows the string to go on and on, when the page is submitted it does not retain the prompt string and display it as it should. If I keep the characters limited I have no problems. Is it possible to set a prompt window to a set number of characters to accept?

yes. for example:

var v = prompt("enter something", "enter something");
v = v.substr( 0, 5 );
alert( v );

don't be sorry. just try to make it a habit of supplying as much information as possible (without clogging the page) so we can help you quicker.

Or, to force the user to only enter less than a set amount of characters, or cancel:

var maxLength = 25;
var userData = -1;

while (userData == -1 || (userData != null && userData.length > maxLength)) {
	userData = window.prompt('Please enter some data. It should be no more than ' + maxLength + ' characters in length', '');
}

Hope this helps,
