/* doajax("someurl" [, 'sometarget'] [, setstatus]);
- set sometarget to the ID of the HTML object you would like results put into (innerHTML)
- setstatus=true will show "Loading...[25%]" status box during ajax.readyState's 1-3
- doajax2 will always return a string named 'tehString' containing the results (see following note)
- The catch with using 'tehString' is that you need to know when it exists; with ajax the JS that called this function will carry on while this function works away in the background. Below is an example of how you can check to see if 'tehString' is available:
var url = "foobar.php";
doajax(url);
wait4ajax = setInterval('ajaxDone()',100);
}
function ajaxDone() {
if (tehString) {
clearInterval(wait4ajax);
alert("All done! Here is tehString: " + tehString);
