How do I limit or restrict the user to only enter a maximum of five characters in the textbox?
Below is the input field as part of my form:
<input type="text" id="sessionNo" name="sessionNum" />
Is it using something like maxSize or something like that?
The maximum number of characters that will be accepted as input. This can be greater that specified by SIZE , in which case the field will scroll appropriately. The default is unlimited.
<input type="text" maxlength="2" id="sessionNo" name="sessionNum" onkeypress="return isNumberKey(event)" />
However, this may or may not be affected by your handler. You may need to use or add another handler function to test for length, as well.
