• 关于HMLT5离线缓存的痛,痛经有多痛就有多痛(hybrid应用加载)


    一、先看下脑图

    二、前面一篇文章简单的说了下manifest文件的缓存。

      前面的文章能解决问题,但是带来了更多的致命问题,最后想到这个办法。

      也碰到了一些关于HTML加载执行的问题,主要是页面和JS执行的顺序问题。

      关于源码暂时还没整理出来~~有需要了解的可以找我交流~~~

    (function(window, undefined) {
    				//资源请求
    				function loadResource(resources, callback) {

    					var index = 0,cacheStr='',errorCache=false;
    					(function _load(ary) {
    						var opt = ary.shift();
    						if (!opt) {
    							localStorage.cacheStrJs=cacheStr;
    							if(!errorCache){
    								localStorage.versioning=versioning;
    								"function" == typeof callback && callback();
