Delete specific char from textfield/String var by bclt
Posted: 18 May 05


  function RemoveChar()
    while (document.form.T1.value.indexOf("'") != -1)
      var WhereItIs;
      WhereItIs = document.form.T1.value.indexOf("'");
      document.form.T1.value = document.form.T1.value.substring(0, WhereItIs) + document.form.T1.value.substring(WhereItIs + 1);

This script removes all single quotes from a textfield (T1) which is in a form (form). When the script is executed the value of the textfield will not contain "'"

Of course can be modified to use the "getElementById()".

That's the "basic" code. With little changes may the function accert as parameters a String variable, such as "abc" and remove all instances of "a", "b" and "c" letters.
