Examples of the differences between JS and Ajax get and post in use _javascript skills

The biggest difference between get and post methods is that:

The 1.get method passes the value parameter inside the URL, and the post parameter is sent inside the send

2.post method must be added

Xmlhttp.setrequestheader ("Content-type", "application/x-www-form-urlencoded");

The following example looks at the Get method

Xmlhttp.open ("Get", "for.php?text=" +url,true);

The post is displayed as:

Xmlhttp.open ("POST", "for.php", true);
Xmlhttp.setrequestheader ("Content-type", "application/x-www-form-urlencoded");

Post and Get methods Common files

index.php

<script src= "A.js" type= "Text/javascript" ></script>
<a href= "#" onclick= "funphp100 (' O ')" >o </a>
<a href= "#" onclick= "funphp100 (' t ')" >t</a>
<a href= "#" onclick= "funphp100 (' x ')" >x</a>

Post Method File:

A.js

var xmlHttp; 
function S_xmlhttprequest () { 
if (window). ActiveXObject) { 
xmlhttp=new activexobject (' microsoft.xmlhttp ');
} else if (window. XMLHttpRequest) { 
xmlhttp=new XMLHttpRequest ();
}
}
function funphp100 (n) {
var data = "text=" +N; Multiple parameters, then add
s_xmlhttprequest ();
Xmlhttp.open ("POST", "for.php", true); 
Xmlhttp.setrequestheader ("Content-type", "application/x-www-form-urlencoded");
xmlhttp.onreadystatechange=byphp;
Xmlhttp.send (data);
}
function byphp () {
var byphp100=xmlhttp.responsetext;
document.getElementById ("php100"). innerhtml=byphp100;

for.php:

?
echo $_post[' text '];

Get method File:

A.js:

var xmlHttp; 
function S_xmlhttprequest () { 
if (window). ActiveXObject) { 
xmlhttp=new activexobject (' microsoft.xmlhttp ');
} else if (window. XMLHttpRequest) { 
xmlhttp=new XMLHttpRequest ();
}
}
function funphp100 (URL) {
s_xmlhttprequest ();
Xmlhttp.open ("Get", "for.php?text=" +url,true); 
xmlhttp.onreadystatechange=byphp; 
Xmlhttp.send (null);
}
function byphp () {
var byphp100=xmlhttp.responsetext;
document.getElementById ("php100"). innerhtml=byphp100;

for.php:

?
echo $_get[' text '];
