The implementation of JQuery plug-in development MD5 Plug-ins

  This article mainly introduces the implementation of jquery development MD5 Plug-ins, the last return is a series of decimal number, in the jquery1.9.2 test pass, the need for friends can refer to the following

The method returns a string of decimal digits, which is tested under jquery1.9.2.     Code as follows: (function ($) { $.md5 = function (o) {  if (null = = O) {   return ' null ';  }   if (typeof o!= "string") {   return ' null ';  }  //Calculate the length of the fill   var fill_data_len = 0;   var data_len = o.length;   var d_l_mod = data_len% Md5_base_len;   if (0!= d_l_mod)    fill_data_len = Md5_base_len-d_l_mod;   if (Fill_data_len < 8)    fill_data_len + = Md5_base_len;
