此代码适用于Firefox，但不适用于IE。 这是我在IE中遇到的错误：

消息：对象不支持此属性或方法行：84 Char：1代码：0
第84行将是post_form_id部分。
IE在for / in循环中变得无足轻重，并包含所有继承的属性和方法。 尝试调整所有for / in循环来添加一个检查，即被迭代的对象实际上已将每个项作为其自己的属性：
for (k in val) {
if (Object.prototype.hasOwnProperty.call(val, k) && val[k] !== null) {
tmp.push(_http_build_query_helper(key + "[" + k + "]", val[k], arg_separator));
}
}
