        var tRow = tRowList[rIndex];
      
      	var rData = {};
      	var tCellList = $(tRow).find("td");
      	for (var cIndex = 0; cIndex < tCellList.length; cIndex++) {
      		var tCell = tCellList[cIndex];
      		if ($(tCell).find("select").length)
      			rData[$(tCell).find("option").prop("value")] = $(tCell).find(

      </table>
      <button id="saveBtn" class="btn btn-primary pull-right">Save</button>
   </body>
   
</html>

I have select Options in a table which is dynamic(I just showed three here).I tried to get the selected value of option and push into array when i click on save button.But when I change the value of select option and click on save button then it is only showing value "1" in when i try to grab the selected value using console.log(allOptionsSelected); .

Though i change the value of these three options it is only showing me "1".It should have been 2 or 3 or 4 according to options selected.

enter image description here

You can just use below statement for get all selected option values

var dataList=[];
$("#saveBtn").click(function(e) {       
    $("#tempTable tbody tr select option:selected").each(function(){
        dataList.push($(this).val())
    })
    console.log(dataList);
});

The code to get the selected option is bit lengthy. I think that can be shorten.

In the click event handler get all select and iterate it. Then use the val method , to get the selected option.

Also not inside the handler the dataList is emptied to remove the previously selected values

var dataList = [];
$("#saveBtn").click(function(e) {
  dataList.length = 0;
  $("#tempTable").find('select').each((i, v) => {
    dataList.push($(v).val())

  });
  console.log(dataList)

})

find(option) will return the first option element it finds so it is always giving one as output. Use find(option:selected) to get the selected option

var dataList = [];
$("#saveBtn").click(function(e) {

  var allOptionsSelected = getEditableTableOptionData("#tempTable");
  console.log(allOptionsSelected);
});

function getEditableTableOptionData(param_table) {
  var tRowList = $(param_table).find("tbody").find("tr");
  var dataList = [];
  for (var rIndex = 0; rIndex < tRowList.length; rIndex++) {
    var tRow = tRowList[rIndex];
    var rData = {};
    var tCellList = $(tRow).find("td");
    for (var cIndex = 0; cIndex < tCellList.length; cIndex++) {
      var tCell = tCellList[cIndex];
      if ($(tCell).find("select").length)
        rData[$(tCell).find("option").prop("value")] = $(tCell).find(
          "option:selected").val();
    }
    dataList.push(rData);
  }
  return dataList.flatMap(e=>Object.values(e));
}
