RichardRotterdam Posted April 8, 2007 Share Posted April 8, 2007 Hi, why not use the maxlenght attribute instead saves you all the javascript programming. example: <input maxlength="100" name="address" type="text"> Link to comment https://forums.phpfreaks.com/topic/45999-solved-field-length-check/#findComment-224417 Share on other sites More sharing options...
veridicus Posted April 8, 2007 Share Posted April 8, 2007 What exactly isn't working? Is the form not posting or is the JS not performing the check properly?

nogray Posted April 9, 2007 Share Posted April 9, 2007 you're checking if the length is smaller than 5 and smaller than 12 if((document.registration.username.value.length < 5)||(document.registration.username.value.length < 12)){ Notice the < sign before the 5 Link to comment https://forums.phpfreaks.com/topic/45999-solved-field-length-check/#findComment-225114 Share on other sites More sharing options...
