How can i update javascript with php?


Recommended Posts

Hello.

 

I have the following code for part of an ajax fuction:

	var a1 = document.getElementById('1').value;
var b2 = document.getElementById('2').value;
var queryString = "?a1=" + a1 + "&b2=" + b2;
ajaxRequest.open("GET", "updatedetails.php" + queryString, true);
ajaxRequest.send(null); 
}

//-->
</script>

 

Although the problem is that i need to be able to change the variables. for example i have 1, 2, 3 fields in my database. For example this code would work in php:

while ($i <= $rowcount){
$result = mysql_query("SELECT * FROM type WHERE type_id = $i") 
or die(mysql_error());  
$qry = mysql_fetch_array($result);
echo "the variable put here";
$i = $i + 1;
}

 

Something like that, but i don't know how to get it into the javascript file. Any ideas?

 

Thanks.

 

P.s. The full ajax code is here:

<script language="javascript" type="text/javascript">
<!-- 
//Browser Support Code
function ajaxFunction(){
var ajaxRequest;  // The variable that makes Ajax possible!

try{
	// Opera 8.0+, Firefox, Safari
	ajaxRequest = new XMLHttpRequest();
} catch (e){
	// Internet Explorer Browsers
	try{
		ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP");
	} catch (e) {
		try{
			ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP");
		} catch (e){
			// Something went wrong
			alert("Your browser broke!");
			return false;
		}
	}
}
// Create a function that will receive data sent from the server
ajaxRequest.onreadystatechange = function(){
	if(ajaxRequest.readyState == 4){
	var ajaxDisplay = document.getElementById('ajaxDiv');
		ajaxDisplay.innerHTML = ajaxRequest.responseText;
	}
}

var MSN = document.getElementById('MSN').value;
var Yahoo = document.getElementById('Yahoo').value;
var queryString = "?MSN=" + MSN + "&Yahoo=" + Yahoo;
ajaxRequest.open("GET", "updatedetails.php" + queryString, true);
ajaxRequest.send(null); 
}

//-->
</script>

let php store the values in an array and then at the end of your loop do:

 

echo "<script language='javascript'>";

 

for($i = 0; $i < sizeof($myarray); $i++){

 

echo "var num" . $myarray[$i] . "=" .  $myarray[$i] .";";

}

echo "</srcipt>";

 

now javascript has global vars named like num1, num2 etc.. which holds the values you got from you DB
