Generalized Ajax function [migrated]
- by TecBrat
Not sure if this question will be considered "off topic". If it is, I'll remove it, but:
I hadn't see this yet so I wrote it and would like to know if this is a good approach to it. Would anyone care to offer improvements to it, or point me to an example of where someone else has already written it better?
function clwAjaxCall(path,method,data,asynch)
{
var xmlhttp;
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
if(asynch)
{
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
//alert(xmlhttp.responseText);
//var newaction=xmlhttp.responseText;
//alert('Action becomes '+newaction);
return xmlhttp.responseText;
}
}
}
if(method=='GET'){path=path+"/?"+data;}
xmlhttp.open(method,path,asynch);
if(method=='GET'){xmlhttp.send();}else{xmlhttp.send(data);}
if (!asynch){return xmlhttp.responseText;}
}
I then called it like
Just Testing
<script type="text/javascript" src="/mypath/js/clwAjaxCall.js"></script>
<script type="text/javascript">
document.write("<br>More Testing");
document.write(clwAjaxCall("http://www.mysite.com",'GET',"var=val",false));
</script>
