javascript - Banners are disappearing from webpage. Any suggestions on how to fix this? -

-

i'm having issue labels @ top of page disappearing after click button. when click "show employees" button, "last name" "first name" , "region name" disappear.

here screenshots:

after clicking "show employees": https://imgur.com/a/pqkoh

i have feeling issue displayemployees js function:

function displayemployees(data) { var table = ""; $.each(data.rows, function(index, row){     table += "<div class='row'>\n";      table += "<div class='col1'>" + row.emp_first + "</div>\n";     table += "<div class='col2'>" + row.emp_last + "</div>\n";     table += "<div class='col3'>" + row.region_name + "</div>\n";     table += "<button dbutton = " + row.employee_id + " class =  'deletebutton'> delete employee </button>";     table += "</div></br>"; });   $("#outputdiv").children("div:not(:first)").remove(); $("#outputdiv").html(table); $("#addemployeebutton").on('click', addemployee); $(".deletebutton").on('click', deleteemployee);

}

$("#outputdiv").children("div:not(:first)").remove(); $("#outputdiv").html(table); $("#addemployeebutton").on('click', addemployee); $(".deletebutton").on('click', deleteemployee);

}

here html:

<!doctype html> <html lang="en">   <head>     <meta charset="utf-8">     <title>employee table</title>     <link rel="stylesheet" type="text/css" href="style.css" /> </head> <body>     <h2 id="title">project 4 web app</h2>     <div id="outputdiv" class="container">         <div class="row">             <div class="col1h">last name</div>             <div class="col2h">first name</div>             <div class="col3h">region name</div>     </div>     </div>     <br>     filter region&nbsp     </br>     <select>     <option value="1">select</option>     <option value="2">nw</option>     <option value="3">sw</option>     <option value="4">mn</option>     <option value="5">ms</option>     <option value="6">ne</option>     <option value="7">se</option>     </select>     <div id="buttondiv"><br>         <button id="showbutton">show employees</button>     </div>     <p>         <h3>to add employee:</h3>         <div class="divcol1">employee first name:</div><div class="divcol12">     <input type="text" id="emp_first"/></div><br>         <div class="divcol1">employee last name:</div><div class="divcol12"><input type="text" id="emp_last"/></div><br>         <br><div class="divcol1">region id:</div><div class="divcol12"><input type="text" id="region_id"/></div><br>          <br><button id="addemployeebutton">add employee</button><br>       <script src="jquery-3.1.1.min.js"></script>     <script src="employee.js"></script> </body> </html>

any appreciated. thank in advance.

your selector isn't correct. instead of

$("#outputdiv").children("div:not(:first)").remove();

try

$("#outputdiv").children("> div:not(:first)").remove();

or shorter:

$("#outputdiv > div:not(:first)").remove();

explanation: selector finds column divs , not rows. take @ jquery documentation more info.
