jquery: bind "click" event

Question

in my bind "click" event, i would like to chop the last character off a given string incrementally. however, each time i click it, it seems to stop after the first chomp.

var somestring = "mary had a little lamb";
$("#removelaststring").unbind("click").bind("click",function(e){

alert(somestring.slice(0,-1))

});

it should return "one less character" each time it's clicked

var somestring = "mary had a little lamb";

// you can use .click( function ) instead of .bind("click", function)
$("#removelaststring").click(function(e){
  // slice & save it
  somestring = somestring.slice(0,-1);
  alert(somestring);
});

okay what about for somestring.replace("/regex/","") ? regex to replace the last character.

Russ Cam Over a year ago

when you say replace the last character using regex, do you want to build the regex at runtime with a pattern that you can specify? Also, do you literally mean the last character or characters matched by the regular expression pattern?

somestring.slice(0,-1) gives you a new string without the last letter, but it doesn't modify somestring. Try alert(somestring = somestring.slice(0,-1));.
