Delete all rows in an HTML table

Question

How can I delete all rows of an HTML table except the  lt th gt  s using Javascript  and without looping through all the rows in the table  I have a very huge table and I don t want to freeze the UI while I m looping through the rows to delete them

Assuming you have just one table so you can reference it with just the type. If you don't want to delete the headers:

$("tbody").children().remove()

otherwise:

$("table").children().remove()

hope it helps!

const table   document querySelector  table    table innerHTML           null   table innerHTML        the above javascript worked fine for me  It checks to see if the table contains any data and then clears everything including the header

If you can declare an ID for tbody you can simply run this function   var node   document getElementById  tablebody    while  node hasChildNodes        node removeChild node lastChild

If you have far fewer  lt th gt  rows than non- lt th gt  rows  you could collect all the  lt th gt  rows into a string  remove the entire table  and then write  lt table gt thstring lt  table gt  where the table used to be   EDIT  Where  obviously   thstring  is the html for all of the rows of  lt th gt s

Assing some id to tbody tag  i e    After this  the following line should retain the table header footer and remove all the rows    document getElementById  yourID   innerHTML       And  if you want the entire table  header rows footer  to wipe out  then set the id at table level i e

Points to note  on the Watch out for common mistakes   If your start index is 0  or some index from begin   then  the correct code is   var tableHeaderRowCount   1  var table   document getElementById  WRITE YOUR HTML TABLE NAME HERE    var rowCount   table rows length  for  var i   tableHeaderRowCount  i  lt  rowCount  i          table deleteRow tableHeaderRowCount       NOTES  1  the argument for deleteRow is fixed this is required since as we delete a row  the number of rows decrease   i e  by the time i reaches  rows length - 1   or even before that row is already deleted  so you will have some error exception  or a silent one    2  the rowCount is taken before the for loop starts since as we delete the  table rows length  will keep on changing  so again you have some issue  that only odd or even rows only gets deleted    Hope that helps

How about this   When the page first loads  do this   var myTable   document getElementById  myTable    myTable oldHTML myTable innerHTML    Then when you want to clear the table   myTable innerHTML myTable oldHTML    The result will be your header row s  if that s all you started with  the performance is dramatically faster than looping
