is not necessary  You know both values are strings so you dont need to compare types    x000D   x000D  function do check   x000D    x000D    var str1       textbox1   val    x000D    var str2       textbox2   val    x000D   x000D    if  str1    str2  x000D      x000D          text   removeClass  incorrect    x000D      alert  equal    x000D      x000D    else x000D      x000D          text   addClass  incorrect    x000D      alert  not equal    x000D      x000D    x000D   incorrect x000D    x000D    background   ff8888  x000D    x000D   lt script src  https   ajax googleapis com ajax libs jquery 2 1 1 jquery min js  gt  lt  script gt  x000D   x000D   lt input id  textbox1  type  text  gt  x000D   lt input id  textbox2  type  text  gt  x000D   x000D   lt button onclick  do check    gt check lt  button gt  x000D   x000D   x000D

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
