var statone; var xhr = new xmlhttprequest(); xhr.open("get", "https://www.dsswym.3ds.com/", true); xhr.onreadystatechange = function() { if (xhr.readystate == 4 && xhr.status==200) { settimeout(function(){ //wait webpage loading statone = $('#widgetpanel-7qrsn8cawqkk0dp2_gqk').text(); console.log(statone); alert(statone); }, 10000); } } xhr.send(); i'm not able text values on above code, instead alert box empty. source site doesn't provide xml or json file, need extract first content or update on site.
you need use response xmlhttprequest. doing xmlhttprequest request doesn't load request resource page.
in jquery, can this:
$.get("https://www.dsswym.3ds.com/", function(data) { // load response text new page element var fakepage = document.createelement("html"); fakepage.innerhtml = data; // find desired element within new page element var statone = $(fakepage).find('#widgetpanel-7qrsn8cawqkk0dp2_gqk').text(); console.log(statone); } }); this stores result of ajax fetch innerhtml of new <html> element, cases text parsed new dom. use jquery's .find method element need out of dom.
