NoTe: On succesfull form submission it will always be 200 .. so it need to check and recheck for 500 and then for 200 before redirecting to the mainpage again.</p> <p>I tried to create checkstatus function so i can resuse. how can this be done correctly?</p> <pre><code> // setTimeout(function() { location.reload(true);}, 3000); function checkStatus() { /*** Re check bit ***/ var restartCheck = window.setInterval( $.ajax({ // dataType : 'jsonp', //jsonp : 'js', url: "../../../../../rest/configuration", beforeSend: function (jqXHR, settings) { console.info('in beforeSend'); console.log(jqXHR, settings); }, error: function (jqXHR, textStatus, errorThrown) { alert(" 500 top data still loading " + jqXHR + " : " + textStatus + " : " + errorThrown); console.info('in error'); console.log(jqXHR, textStatus, errorThrown); }, complete: function (jqXHR, textStatus) { alert(" complete " + jqXHR + " : " + textStatus); console.info('in complete'); console.log(jqXHR, textStatus); }, success: function (data, textStatus, jqXHR) { window.clearInterval(restartCheck); alert(" success " + jqXHR + " : " + textStatus); console.info('in success'); console.log(data, textStatus, jqXHR); } }), 3000); //This will call the ajax function every 3 seconds until the clearInterval function is called in the success callback. /*** recheck bit **/ } </code></pre> <p>/** On initial success form submission the success values is 200. After that I need to wait sometimes to check and recheck for 500 for server starts, when the Server restarts or is restarting it gives a 500 internal server message, it take about 30 to 40 sec or more to restart the server so i have await time for 30 sec.. Once the server restarts it gives a 200 success server message. and then redirect the page . SO i am trying to checkstatus until it changes from 200 --> 500 -200 **/</p> <pre><code> $.ajax({ type: "POST", url: "foo.json", data: json_data, contentType: 'application/json', success: function (data, textStatus, xhr) { console.log(arguments); console.log(xhr.status); alert("Your changes are being submitted: " + textStatus + " : " + xhr.status); $('#myModal').modal('hide'); $('#myModal-loading').modal('show'); //call function checkstatus not currently workign //statsu val ==200 server inital form success val from server setTimeout(function () { count=0; var statusval = checkStatus(); while(statusval == 200 and count <=5) { statusval = checkStatus(); //statsu val has changed to 500 server is restarting if (statusval==500) { //wait for 30 sec to recheck if the server has restarted and changed to success ie 200 setTimeout(function () { checkStatus();}, 30000); } count++; }, 3000); alert("restartCheck " + restartCheck) setTimeout(function () { location.reload(true); }, 3000); // $('#myModal-loading').modal('hide'); $('<div id="loading">Loading...</div>').insertBefore('#myform'); //location.reload(true); }, error: function (jqXHR, textStatus, errorThrown) { // alert("Warning and error has occured: "+errorThrown + " : " + jqXHR.status); alert(jqXHR.responseText + " - " + errorThrown + " : " + jqXHR.status); } }); }); }); </code></pre>
