php parameter passing method 1--ajax, php1--ajax

AJAX is "Asynchronous Javascript And XML "" (Asynchronous JavaScript and XML) refers to a web development technology for creating interactive web applications. AJAX = Asynchronous JavaScript and XML (a subset of Standard Universal Markup Language). AJAX is a technology for creating fast, dynamic web pages. AJAX enables web pages to update asynchronously by exchanging small amounts of data with the server in the background. This means that parts of a page can be updated without reloading the entire page. Traditional web pages (not using AJAX) must reload the entire web page if content needs to be updated. Asynchronous request (XMLHttpRequest object) , partial refresh (essentially js dom) Ajax is also used to automatically determine whether the user name is repeated when filling out a form. For example, if you are halfway through writing a blog and suddenly your computer restarts, you can restore half of the content you wrote. ​ Get is used to obtain data. There is a word limit. The request is included in the URL. Post has no limit and is used to modify the content of the server. Get is a safe request and needs to ensure that the information is not modified. 1. Ajax is generally used for the current page and does not implement page jumps

2. Ajax side: How to asynchronously monitor the status of the server side? Monitor the readystate attribute through onreadystatechange

request.onreadystatechange = function() {

<span>if (request.readyState===4) {</span>
  • 0: The request is not initialized ( has not been called yet). open()
  • 1: The request has been established, but has not been sent yet ( has not been called yet). send()
  • 2: The request has been sent and is being processed (usually the content headers can now be obtained from the response).
  • 3: The request is being processed; usually some data is available in the response, but the server has not yet completed generating the response.
  • 4: The response is complete; you can get and use the server's response.
So generally, the corresponding operation is performed after judging that it is equal to 4.

But please note that this is different from the status of request

For example, readystate=4 but status=404 means that the response is completed but the content of the response is that the file was not found

So the general approach is to return the content when ==200, and otherwise just display the sound error.

Note that in the post request, you must set the url to encode and

url decoding, otherwise the result will not be given correctly

request.setRequestHeader("Content-type","application/x-www-form-urlencoded");

But there is a problem with url decoding. Since the plus sign will be automatically decoded into a space when urlencoded, & will be decoded into a variable connector, so if these characters appear, they must be transcoded

(I encountered this problem when making the URL for uploading images to canvas)

Pic = Pic.replace(/ /g, "+");

Pic = Pic.replace(/&/g, "&");
3. The server returns to the interface passing ajax through echo. (Tip: zendstudio’s built-in browser will always display the last page for ajax pages, so run it in an external browser instead. Setting in preference-general-web browser. ) If you only return a simple row, you don't need Jason. Jason can more conveniently return data with different key values.
