Write javascript code in PHP

Question

My index.php

 switch ($action){
 case "calendar":
 echo "<script language=\"javascript\">\n";
 echo "document.write('Hello World!')";
 echo "</script>";
 include($_STR_TEMPLATEPATH."/calendar_view.php");
 break;
 }

my calendar_view.php:

I have an ajax function which should call the action calendar from the index and display the result on calendar_view.php in calendar div

<script>
 function calendarList()
 {
 var xmlHttp;
 try
 {
 // Firefox, Opera 8.0+, Safari
 xmlHttp=new XMLHttpRequest();
 }
 catch (e)
 {
 // Internet Explorer
 try
 {
 xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
 }
 catch (e)
 {
 try
 {
 xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
 }
 catch (e)
 {
 alert("Your browser does not support AJAX!");
 return false;
 }
 }
 }
 xmlHttp.onreadystatechange=function()
 {
 if (xmlHttp.readyState==4 && xmlHttp.status==200)
 {
 document.getElementById("calendar").innerHTML=xmlHttp.responseText;
 }
 }
 xmlHttp.open("GET","?action=calendar",true);
 xmlHttp.send(null);
 }
 </scritp>

The calendar div:

<div id="calendar"></div>

When I call the calendarList function it did call the case, but did not display the result in calendar div.

Any help. Thanks

Answer 1

There is not much to display there. If everything works like you described, the response is appended to the DOM, but the JavaScript-alert will never be executed.

Try alert(xmlHttp.responseText); to be absolutely sure that your response is correct. If it is, you can go from there.

• alkhader: I added alert(xmlHttp.responseText); to the script but nothing come out
• alkhader: But, if I open the inspect element with Firebug in FireFox and open the request "GET" under Response I can see it prints out the script
• Amberlamps: @alkhader: Then it MUST alert your response when you use alert(xmlHttp.responseText);.
• alkhader: Yes Got it. It alerts the scripts now,

Instead of using a script to write thee text just output text

switch ($action){
 case "calendar":
 echo "Hello World!";
 include($_STR_TEMPLATEPATH."/calendar_view.php");
 break;
}

I don't think inserting scripts with innerHTML works see Can scripts be inserted with innerHTML?

• alkhader: Thank you, the text example just to make my post easy. Actually I need to write a complex script.
