| 31 // How we handle the base tag better. | |
| 32 // Current status: | |
| 33 // At now the normal way we use to handling base tag is | |
| 34 // a) For those links which have corresponding local saved files, such as | |
| 35 // savable CSS, JavaScript files, they will be written to relative URLs which | |
| 36 // point to local saved file. Why those links can not be resolved as absolute | |
| 37 // file URLs, because if they are resolved as absolute URLs, after moving the | |
| 38 // file location from one directory to another directory, the file URLs will | |
| 39 // be dead links. | |
| 40 // b) For those links which have not corresponding local saved files, such as | |
| 41 // links in A, AREA tags, they will be resolved as absolute URLs. | |
| 42 // c) We comment all base tags when serialzing DOM for the page. | |
| 43 // FireFox also uses above way to handle base tag. | |
| 44 // | |
| 45 // Problem: | |
| 46 // This way can not handle the following situation: | |
| 47 // the base tag is written by JavaScript. | |
| 48 // For example. The page "www.yahoo.com" use | |
| 49 // "document.write('<base href="http://www.yahoo.com/"...');" to setup base URL | |
| 50 // of page when loading page. So when saving page as completed-HTML, we assume | |
| 51 // that we save "www.yahoo.com" to "c:\yahoo.htm". After then we load the saved | |
| 52 // completed-HTML page, then the JavaScript will insert a base tag | |
| 53 // <base href="http://www.yahoo.com/"...> to DOM, so all URLs which point to | |
| 54 // local saved resource files will be resolved as | |
| 55 // "http://www.yahoo.com/yahoo_files/...", which will cause all saved resource | |
| 56 // files can not be loaded correctly. Also the page will be rendered ugly since | |
| 57 // all saved sub-resource files (such as CSS, JavaScript files) and sub-frame | |
| 58 // files can not be fetched. | |
| 59 // Now FireFox, IE and WebKit based Browser all have this problem. | |
| 60 // | |
| 61 // Solution: | |
| 62 // My solution is that we comment old base tag and write new base tag: | |
| 63 // <base href="." ...> after the previous commented base tag. In WebKit, it | |
| 64 // always uses the latest "href" attribute of base tag to set document's base | |
| 65 // URL. Based on this behavior, when we encounter a base tag, we comment it and | |
| 66 // write a new base tag <base href="."> after the previous commented base tag. | |
| 67 // The new added base tag can help engine to locate correct base URL for | |
| 68 // correctly loading local saved resource files. Also I think we need to inherit | |
| 69 // the base target value from document object when appending new base tag. | |
| 70 // If there are multiple base tags in original document, we will comment all old | |
| 71 // base tags and append new base tag after each old base tag because we do not | |
| 72 // know those old base tags are original content or added by JavaScript. If | |
| 73 // they are added by JavaScript, it means when loading saved page, the script(s) | |
| 74 // will still insert base tag(s) to DOM, so the new added base tag(s) can | |
| 75 // override the incorrect base URL and make sure we alway load correct local | |
| 76 // saved resource files. | |
