javascript - Iterate through table and create an array in js/jquery -

-



i want iterate through dynamically created table , create array of elements project name, client name, , field rate @ each index populate , pass through json object

here how table looks:

        <table id="project-table" class="table table-striped table-hover">         <thead>         <tr>             <th>project name</th>             <th>client name</th>             <th>field rate</th>             <th>delete row</th>         </tr>         </thead>         <tbody>         <%--jquery append our data here...     --%>         </tbody>     </table>     <button type="button" onclick="projecttable()" class="btn btn-primary">add row</button>  function projecttable() {  projectrows = projectrows + 1;  var $tbody = $('#project-table').find('tbody'); var $id = $(""); var $tr = $("<tr>");  $id.append(     "<hidden id='projectid'/>" +     "<hidden id='projectversion'/>" );  $tr.append(     "<td>" + "<input class='form-control' id='inputprojectname' placeholder='project name' type='text'>" + "</td>" +     "<td>" + "<input class='form-control' id='inputclientname' placeholder='client name' type='text'>" + "</td>" +     "<td>" + "<input class='form-control' id='inputrate' placeholder='rate' type='text'></td>" +     "<td>" + "<input type='button' value='delete' onclick='deleterow(this)'>" + "</td>"); $tbody.append($id); $tbody.append($tr);}

projecttable() called each time click add new row button. want able depending on how many rows have been created create array containining info each of rows so:

            projectlist: [             {                 id: projectid,                 version: projectversion,                 projectname: projectname,                 clientname: clientname,                 fieldrate: fieldrate             }

but multiple objects have tried few different loops haven't worked me.

you selecting tr , each of select input elements build data.

some issues in current code:

  • you cannot have static id property values in rows, id values must unique
  • the custom hidden element cannot child of tbody. don't see how need element.

i have altered other things in code make more jquery-like:

function projecttable() {      $('#project-table>tbody').append(          $("<tr>").append(              $("<td>").append($("<input>").addclass("form-control")                  .attr({placeholder: "project name", type: "text"})),              $("<td>").append($("<input>").addclass("form-control")                  .attr({placeholder: "client name", type: "text"})),              $("<td>").append($("<input>").addclass("form-control")                  .attr({placeholder: "rate", type: "text"})),              $("<td>").append($("<input>").addclass("form-control delete")                  .attr({type: "button"}).val("delete"))          )      );  }    $(document).on("click", ".delete", function () {      $(this).closest("tr").remove();  });    $('#get').click(function () {      var data = $.map($('#project-table>tbody>tr'), function (tr) {          var $inp = $('input', tr);          return {              project: $inp.eq(0).val(),              client: $inp.eq(1).val(),              rate: $inp.eq(2).val(),          };      });      $('#jsonout').text(json.stringify(data, null, 2));      });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <table id="project-table" class="table table-striped table-hover">      <thead>      <tr>          <th>project name</th>          <th>client name</th>          <th>field rate</th>          <th>delete row</th>      </tr>      </thead>      <tbody>      </tbody>  </table>  <button type="button" onclick="projecttable()" class="btn btn-primary">add row</button>  <button type="button" id="get" class="btn btn-primary">get json</button>  <pre id="jsonout"></pre>
