javascript - AJAX request not working on remote host -


i've got ajax request pulls data form , posts api. weird thing works fine on localhost fails silently when upload remote server. , mean silently: response code blank, there's nothing in logs. i've checked on firefox , chrome. jquery loaded, function firing properly. code below:

function send() {     console.log("preparing");     var beacon = {         beaconid: $("#beaconid").val(),         name:$("#beaconname").val(),         campaignid:$("#campaignid").val(),         clientid:$("#clientid").val()     }     console.log("payload:");     console.log(beacon);      $.ajax({         type: 'post',         url: '../beaconapi/index.php/createbeacon',         data: json.stringify(beacon),         contenttype: "application/json; charset=utf-8",         traditional: true,         success: function (response) {             console.log("done:");             console.log(response);         },         error: function(jqxhr, textstatus, errorthrown) {             console.log(json.stringify(jqxhr));             console.log("ajax error: " + textstatus + ' : ' + errorthrown);          }     }); }

from comments posted

10:33:21.046 "{"readystate":0,"responsetext":"","status":0, "statustext":"error"}" addbeacon.html:34 10:33:21.046 "ajax error: error : "

a status code of 0 means 1 of 2 things:

  1. you running off file protocol
  2. the page refreshed ajax call made

since said on production, sounds case of #2.

so need cancel action causing page refresh. since not show how call send, here basic ways of cancelling action. 

onclick="send(); return false"  onsubmit="send(); return false"  $("#foo").on("click", function(e) {     send();     e.preventdefault(); });

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .

identifier - Is it possible for an html5 document to have two ids? -

i wondering if html5 element can have 2 ids, this: <button id="thing1" id="thing2" name="button1" onclick="change()">click here</button> or this: <button id="thing1, thing2" name="button1" onclick="change()">click here</button> also, if 1 of ids said 1 thing, , other id said thing, 1 used? tl;dr : no. in versions of html, each element can have 1 id. see the spec : the id attribute specifies element's unique identifier (id). [dom] the value must unique amongst ids in element's home subtree , must contain @ least 1 character. the value must not contain space characters. note: there no other restrictions on form id can take; in particular, ids can consist of digits, start digit, start underscore, consist of punctuation , etc. note: element's unique identifier can used variety of purposes, notably way link specific parts of document usin
