vue-simple/lib/utils/hash.js

Use Vue in the simplest and easiest way, contain more than one of plugins and other to do that, i hope you will like it.

var I64BIT_TABLE = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789'.split('');

/**
 * 根据指定内容生成对应哈希编码
 * @param {String} [input]
 * @return {String}
 */
function hash(input) {
  var hv = 0;
  var src = input;
  var i = 0;
  if (src === undefined) {
    var rnd = Math.random().toString(16);
    var stamp = new Date().getTime().toString(16);
    src = rnd + stamp;
  }
  if (typeof src !== 'string') src = input.toString();
  i = src.length - 1;
  for (; i > -1; i--) {
    hv += (hv << 3) + src.charCodeAt(i);
  }
  var value = hv & 0x7FFFFFFF;
  var retValue = '';
  do {
    retValue += I64BIT_TABLE[value & I64BIT_TABLE.length - 1];
  } while (value >>= 3);
  return retValue;
}

/**
 * 生成请求时所需唯一标识码（out_request_no）
 * @returns {string}
 */
function timehash() {
  var date = new Date();
  var p = {
    y: date.getFullYear(),
    m: ('0' + (date.getMonth() + 1)).substr(-2),
    d: ('0' + date.getDate()).substr(-2),
    h: ('0' + date.getHours()).substr(-2),
    i: ('0' + date.getMinutes()).substr(-2),
    s: ('0' + date.getSeconds()).substr(-2)
  };
  return '' + p.y + p.m + p.d + p.h + p.i + p.s + hash();
}

export { hash, timehash };
