由于window.name没有兼容性问题，基于同一个窗口共享数据，所以想实现在同一个窗口加载不同页面使它们共享数据，就想到用window.name，请问这样使用window.name靠谱么？？？
用localStorage吧，有兼容IE低版本的方案。
"use strict";
//localStorage support ie6-8
if(typeof window.localStorage === 'undefined'){
var localStorage = window.localStorage = {},
prefix = 'data-userdata',
doc = document,
attrSrc = doc.body,
html = doc.documentElement,
// save attributeNames to <html>'s
// data-userdata attribute
mark = function (key, isRemove, temp, reg) {
html.load(prefix);
temp = html.getAttribute(prefix);
reg = new RegExp('\\b' + key + '\\b,?', 'i');
var hasKey = reg.test(temp) ? 1 : 0;
temp = isRemove ? temp.replace(reg, '').replace(',', '') :
hasKey ? temp : temp === '' ? key :
temp.split(',').concat(key).join(',');
html.setAttribute(prefix, temp);
html.save(prefix);
};
// add IE behavior support
attrSrc.addBehavior('#default#userData');
html.addBehavior('#default#userData');
localStorage.getItem = function (key) {
attrSrc.load(key);
return attrSrc.getAttribute(key);
};
localStorage.setItem = function (key, value) {
attrSrc.setAttribute(key, value);
attrSrc.save(key);
mark(key);
};
localStorage.removeItem = function (key) {
attrSrc.removeAttribute(key);
attrSrc.save(key);
mark(key, 1);
};
// clear all attributes on <body> that using for textStorage
// and clearing them from the 'data-userdata' attribute's value of <html>
localStorage.clear = function () {
html.load(prefix);
var attrs = html.getAttribute(prefix).split(','),
len = attrs.length;
for (var i = 0; i < len; i++) {
attrSrc.removeAttribute(attrs[i]);
attrSrc.save(attrs[i]);
}
html.setAttribute(prefix, '');
html.save(prefix);
};
}IE低版本用userData存储。(代码来自网络)
