How to limit the character number in bracket using javascript
Hi i have this this text.
[If you purchased or upgraded RegexBuddy after 13 June 2007, you can download the latest version by ][typing in your email address and RegexBuddy user ID below.]
Right now the the open and close bracket indicate it is 100 and below characters (using javascript).
How do i prevent user from enter other words between the bracket that will make it more than 100 chars?
I dont want to prevent user from input anything, i just want to prevent the sentence in the bracket will not exceed 100 chars.开发者_开发百科
Thank you.
Quick 'n' dirty:
$(someElementOrSelector).keydown(function(e) {
var bracket_start = $(this).text().indexOf('['),
bracket_end = $(this).text().lastIndexOf(']');
if((bracket_end - bracket_start) > 100) {
e.preventDefault();
return false;
}
});
I think you can try to match 100 character in bracket if yu have a match you should display on alert or what ever is convenient to you.
if (myString.match(/\[.{100}[^\]]+\]/))
{
alert('you have too many characters');
}
you can put a function on keypress event that count the length of the particular div, and then will check if that counter > 100 then will popup message will displayed and return false.
Thanks.
