Question

我想运行一个for循环，它会在表格的文本框中插入一个单词;然后在文本框中插入一个新单词。

但是，当我点击提交时，我只有一个单词可以在没有ajax的情况下执行此操作吗？

function check()
{
  var myrows = new Array();
  myrows[0] = "row1";
  myrows[1] = "row2";

  var server =" ";
  var root = " ";

  for (var i=0;i<myrows.length;i++){

    root = myrows[i]+ "rootname";
    server = myrows[i]+ "servername";
    var j = document.getElementById(root);
    var y = document.getElementById(server);

    document.getElementById('id_rootname').value=j.textContent;
    document.getElementById('id_servername').value=y.textContent;

  }

  var x;
  var r=confirm("Are you sure you?" );
  if (r==true)
  {
    x="You pressed OK!";
  }
  else
  {
    Object.cancel;
  }  

}
</script>


        <tr >
    <td align="center"><input type="checkbox"  class="selectedId"
    onclick="resetSelectedAll(this);" id= "check" value="row1" name="row{{ forloop.counter }" ></td>

Answer 1

root = myrows[i]+ "rootname";
server = myrows[i]+ "servername";
var j = document.getElementById(root);
var y = document.getElementById(server);

 instead of this try this one.



start var i = 1 in for loop.
var j= document.getElementById("row"+i+"rootname");

对于循环不能正常工作
