ajax预加载页面的问题。
B页面中有flash,打开时有点慢。在A页面中包含B页面的链接,现在想在打开A的时候,利用ajax偷偷加载B页面,可以加载过来了,可是再打开B页面的时候,速度还是很慢,好像浏览器没有缓存住B页面的内容。A页面中代码如下:
- JScript code
<!-- Code highlighting produced by Actipro CodeHighlighter (freeware) http://www.CodeHighlighter.com/ --> $(document).ready( function (){ $.ajax({ type: "get", url: "/img/"+url_part, data: "", success: function(msg) { } }) });
------解决方案--------------------
你那算不上缓存吧。你访问B页面时又没有从ajax中返回的值取。
------解决方案--------------------
你可以藏个iframe。。。
------解决方案--------------------
但是 ajax 是不会写缓存的
------解决方案--------------------
ajax能够设立缓存!我觉得用ajax这样加载,b页面的显示速度会更慢些,本来ajax就不适合做大数据的传速!
请教下:flash浏览器能够是否能够产生缓存吗?
------解决方案--------------------
所以浏览器都是这样吧。不仅仅对于flash,对于html网页也会产生缓存。
------解决方案--------------------
------解决方案--------------------
听说jq 有个缓存参数
cache:true
------解决方案--------------------
浏览器写缓冲区是必然的内置功能,如果你的flash是swf后缀则一定会缓存的
除非有禁止缓存的头
但对 js 能写浏览器缓冲区表示怀疑,如果真的可以的话,不就可以将任何文件写入用户的硬盘了吗?

Build an autocomplete suggestion engine using PHP and Ajax: Server-side script: handles Ajax requests and returns suggestions (autocomplete.php). Client script: Send Ajax request and display suggestions (autocomplete.js). Practical case: Include script in HTML page and specify search-input element identifier.

Ajax (Asynchronous JavaScript and XML) allows adding dynamic content without reloading the page. Using PHP and Ajax, you can dynamically load a product list: HTML creates a page with a container element, and the Ajax request adds the data to that element after loading it. JavaScript uses Ajax to send a request to the server through XMLHttpRequest to obtain product data in JSON format from the server. PHP uses MySQL to query product data from the database and encode it into JSON format. JavaScript parses the JSON data and displays it in the page container. Clicking the button triggers an Ajax request to load the product list.

In order to improve Ajax security, there are several methods: CSRF protection: generate a token and send it to the client, add it to the server side in the request for verification. XSS protection: Use htmlspecialchars() to filter input to prevent malicious script injection. Content-Security-Policy header: Restrict the loading of malicious resources and specify the sources from which scripts and style sheets are allowed to be loaded. Validate server-side input: Validate input received from Ajax requests to prevent attackers from exploiting input vulnerabilities. Use secure Ajax libraries: Take advantage of automatic CSRF protection modules provided by libraries such as jQuery.
