I want to post value from index.php, then get the value by self without refresh the page. one botton with two values, I want explode them and finally get $namea and $nameb. then use them in other php part.
but when I use echo $name, in the source code, I can see <div id='msg'></div>(html tag), this is not a pure value, so I tried to use strip_tags, but the value lost. it seems the left the ajax pointed div tag, the value also gone.
index.php
PHP Code:
<head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <script language="javascript"> function saveUserInfo() { var msg = document.getElementById("msg"); var f = document.user_info; var userName = f.user_name.value; var url = "value.php"; var postStr = "user_name="+ userName; var ajax = false; if(window.XMLHttpRequest) { ajax = new XMLHttpRequest(); if (ajax.overrideMimeType) { ajax.overrideMimeType("text/xml"); } } else if (window.ActiveXObject) { try { ajax = new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { try { ajax = new ActiveXObject("Microsoft.XMLHTTP"); } catch (e) { } } } if (!ajax) { window.alert("wrong"); return false; } ajax.open("POST", url, true); ajax.setRequestHeader("Content-Type","application/x-www-form-urlencoded"); ajax.send(postStr); ajax.onreadystatechange = function() { if (ajax.readyState == 4 && ajax.status == 200) { var myPhpVariable = ajax.responseText; msg.innerHTML = myPhpVariable; // myPhpVariable is now a variable which you can use alert( myPhpVariable ); } } } </script> </head> <body> <?php echo $name="<div id='msg'></div>"; $name1=strip_tags($name); $name2 = explode("|",$name1); $namea=$name2[0]; $nameb=$name2[1]; ?> <form name="user_info" id="user_info" method="post"> <input name="user_name" type="hidden" value="abc|def" /><br /> <input type="button" value="abc|def" onClick="saveUserInfo()"> </form> </body>
