最近在学校里面浏览博客的时候出现了一些文章加载不出来的情况，显示一直在转圈，因为学校里面不好操作，而且这个问题也从来没被复现过，于是就发现

是由于Handsome使用了Foreach()的问题

经过检验源码，发现Handsome在两个位置使用了Foreach()函数

所以，在Foreach使用前先自定义一个Foreach

// Production steps of ECMA-262, Edition 5, 15.4.4.18
// Reference: https://es5.github.io/#x15.4.4.18

if (!Array.prototype['forEach']) {

  Array.prototype.forEach = function(callback, thisArg) {

    if (this == null) { throw new TypeError('Array.prototype.forEach called on null or undefined'); }

    var T, k;
    // 1. Let O be the result of calling toObject() passing the
    // |this| value as the argument.
    var O = Object(this);

    // 2. Let lenValue be the result of calling the Get() internal
    // method of O with the argument "length".
    // 3. Let len be toUint32(lenValue).
    var len = O.length >>> 0;

    // 4. If isCallable(callback) is false, throw a TypeError exception.
    // See: https://es5.github.com/#x9.11
    if (typeof callback !== "function") { throw new TypeError(callback + ' is not a function'); }

    // 5. If thisArg was supplied, let T be thisArg; else let
    // T be undefined.
    if (arguments.length > 1) { T = thisArg; }

    // 6. Let k be 0
    k = 0;

    // 7. Repeat, while k < len
    while (k < len) {

      var kValue;

      // a. Let Pk be ToString(k).
      //    This is implicit for LHS operands of the in operator
      // b. Let kPresent be the result of calling the HasProperty
      //    internal method of O with argument Pk.
      //    This step can be combined with c
      // c. If kPresent is true, then
      if (k in O) {

        // i. Let kValue be the result of calling the Get internal
        // method of O with argument Pk.
        kValue = O[k];

        // ii. Call the Call internal method of callback with T as
        // the this value and argument list containing kValue, k, and O.
        callback.call(T, kValue, k, O);
      }
      // d. Increase k by 1.
      k++;
    }
    // 8. return undefined
  };
}

在 /www/wwwroot/www.ioioi.cn/usr/themes/handsome/component/header.php中 44行左右的一个 <script type="text/javascript">中定格添加

直接放弃，更换ie为origin解析
