the images database not coming out in json page , html page image source name outputted. how make images show on html page?

thank precious time.

linejson.php page

<?php header("access-control-allow-origin: *"); header("content-type: application/json; charset=utf-8");  $conn = new mysqli("localhost", "db_user", "db_pwd", "db_name");  $result = $conn->query("select tbl_users.image, tbl_users.firstname, tbl_users.lastname, tbl_users.username,    tbl_posts.post, tbl_posts.post_date                     tbl_posts inner join tbl_users on  tbl_users.id=tbl_posts.user_id                     tbl_posts.user_id=3");  $outp = "["; while($rs = $result->fetch_array(mysqli_assoc)) { if ($outp != "[") {$outp .= ",";}  $outp .= '{"image":"'  . $rs["image"] . '",'; $outp .= '"firstname":"'   . $rs["firstname"]     . '",'; $outp .= '"lastname":"'  . $rs["lastname"] . '",'; $outp .= '"username":"'   . $rs["username"]        . '",'; $outp .= '"post":"'   . $rs["post"]        . '"}';  } $outp .="]";  $conn->close();  echo($outp); ?>

linejson.html page

<!doctype html> <html>  <head> <style>   table, th , td  {  border-top: 1px solid purple;  border-collapse: collapse;  padding: 15px;  } table tr:nth-child(odd) { background-color: #f0f1f1;  } table tr:nth-child(even) { background-color: #ffffff; } </style> </head>  <body> <div id="timeline"></div>  <script> var xmlhttp = new xmlhttprequest(); var url = "http://www.outpaceng.com/linejson.php";  xmlhttp.onreadystatechange=function() { if (xmlhttp.readystate == 4 && xmlhttp.status == 200) {     myfunction(xmlhttp.responsetext);   }   } xmlhttp.open("get", url, true); xmlhttp.send();  function myfunction(response) { var arr = json.parse(response); var i; var out = "<table>";  for(i = 0; < arr.length; i++) {     out += "<tr><td>" +     arr[i].image +     "</td><td>" +     arr[i].firstname +     "&nbsp;" +     arr[i].lastname +     "&nbsp;" +     arr[i].username +     "<br>" +     arr[i].post +     "</td><tr>" ;     }    out += "</table>";    document.getelementbyid("timeline").innerhtml = out;  }  </script>  </body>  </html>

the code can sipmlified , should use json_encode creating json

change this

$outp = "["; while($rs = $result->fetch_array(mysqli_assoc)) { if ($outp != "[") {$outp .= ",";}  $outp .= '{"image":"'  . $rs["image"] . '",'; $outp .= '"firstname":"'   . $rs["firstname"]     . '",'; $outp .= '"lastname":"'  . $rs["lastname"] . '",'; $outp .= '"username":"'   . $rs["username"]        . '",'; $outp .= '"post":"'   . $rs["post"]        . '"}';  } $outp .="]";  $conn->close();  echo($outp);

to 

echo json_encode($result->fetch_all()); $conn->close();

and javascript

for(i = 0; < arr.length; i++) {     out += "<tr><td><img src='" +     arr[i].image +     "' alt="img"/></td><td>" +     arr[i].firstname +     "&nbsp;" +     arr[i].lastname +     "&nbsp;" +     arr[i].username +     "<br>" +     arr[i].post +     "</td><tr>" ; }

java - Static nested class instance -

this question has answer here: java inner class , static nested class 23 answers i came across in java, know static nested class why create instance of 'static'. isn't whole idea of 'static' use without instance? understand concept of inner classes, why (and frankly how possible to) create 'instance' of 'static' member @ ? why this: 1- outerclass.staticnestedclass nestedobject = new outerclass.staticnestedclass(); 2- nestedobject.anestedclassmethod(); and not this: 1- outerclass outerinstance=new outerclass(); 2- outerinstance.staticnestedclass.anestedclassmethod(); use on inner classes, keyword static indicates can access inner class without instance of outer class. for example: public class outer { public static class inner { /* code here. */ } } with construction, can create instance of inn

JavaScript - Replace variable from string in all occurrences -

ok, know if have character '-' , want remove in places in string javascript, ... someword = someword.replace(/-/g, ''); but, when applying array of characters, s not working ... const badchars = ('\/:*?"<>|').split(''); let filename = title.replace(/ /g, '-').tolocalelowercase(); (let item = 0; item < badchars.length; item++) { // below not work global '/ /g' filename = filename.replace(/badchars[item]/g, ''); } any ideas? /badchars[item]/g looks badchars , literally, followed i , t , e , or m . if you're trying use character badchars[item] , you'll need use regexp constructor, , you'll need escape regex-specific characters. escaping regular expression has been well-covered . using that: filename = filename.replace(new regexp(regexp.quote(badchars[item]), 'g'), ''); but , don't want that. want character class: let filename = title.replac
