c# - php code as converted in asp.net not working as expected? -
doing example of ajax, user type in textbox , text continuously posted using javascript , simultanously showing result whether item available or not.
main html as
<body> <h3>the chuff bucket </h3> enter food order: <input type="text" id="userinput" onfocus="process()"/> <div id="underinput"/> </body> here code javascript
var xmlhttp = createxmlhttprequestobject(); function createxmlhttprequestobject() { var xmlhttp; if (window.activexobject) { try { xmlhttp = new activexobject("microsoft.xmlhttp"); } catch (e) { xmlhttp = false; } } else { try { xmlhttp = new xmlhttprequest(); } catch (e) { xmlhttp = false; } } if (!xmlhttp) { alert("cant create object boss!"); } else return xmlhttp; } function process() { if (xmlhttp.readystate == 0 || xmlhttp.readystate == 4) { food = encodeuricomponent(document.getelementbyid("userinput").value); xmlhttp.open("get", "foodstore.aspx?food=" + food, true); xmlhttp.onreadystatechange = handleserverresponse; xmlhttp.send(null); } else { settimeout('process()', 1000); } } function handleserverresponse() { if (xmlhttp.readystate == 4) { if (xmlhttp.status == 200) { xmlresponse = xmlhttp.responsexml; xmldocumentelement = xmlresponse.documentelement; message = xmldocumentelement.firstchild.data; document.getelementbyid("underinput").innerhtml = '<span style = "color:blue;">' + message + '</span>'; settimeout('process()', 1000); } else { alert('something went wrong'); } } } the code php working fine is
<?php header('content-type: text/xml'); echo '<?xml version="1.0" encoding="utf-8" standalone="yes" ?>'; echo '<response>'; $food = $_get['food']; $foodarray = array("tuna","bacon","beef","mutton","biryani"); if($food == '') echo 'enter food idiot.'; else{ if(in_array($food,$foodarray)) echo 'we have '.$food.'!'; else echo 'we not sell '.$food.'!'; } echo '</response>'; ?> but when converted asp.net postback , and working not showing reult inside div. main cause figure out relating echo lines
protected void page_load(object sender, eventargs e) { response.contenttype = "text/xml"; system.diagnostics.debug.print("<?xml version=\"1.0\" encoding=\"utf-8\" standalone=\"yes\" ?>"); system.diagnostics.debug.print("<response>"); string food = (string)request.querystring["food"]; string[] foodarray = new string[] { "tuna", "beef", "mutton", "fish","biryani" }; if (string.isnullorempty(food)) { system.diagnostics.debug.print("enter food idiot."); } else { if (foodarray.contains(food)) { system.diagnostics.debug.print("we serve " + food); } else { system.diagnostics.debug.print("we not serve " + food); } } system.diagnostics.debug.print("</response>"); } note: have tried instead of print response.write result same div id=underinput not getting result. here please.
make sure have replaced system.diagnostics.debug.print response.write. then, check html markup on foodstore.aspx.
foodstore.aspx should have @page directive, nothing else.. want return xml content, need make sure there no doctype or html elements on page.
