You can use javascript dedicate string compare method string1 localeCompare string2   it will five you -1 if the string not equals  0 for strings equal and 1 if string1 is sorted after string2    lt script gt      var to check   this  val        var cur string     0   text        var to chk    that       var cur str   that       if to chk localeCompare cur str     0           alert  both are equal                0   attr  class   correct              else           alert  both are not equal                0   attr  class   incorrect           lt  script gt
