我有一个可以动态添加行的表。当我提交保存按钮时，我想将每一行中的数据获取到一个 php 数组。请有人帮我解决这个问题。我是 java-script 的新手，对它知之甚少。谢谢！

<HTML>
<HEAD>
    <TITLE> Add/Remove dynamic rows in HTML table </TITLE>
    <SCRIPT language="javascript">
        function addRow(tableID) {

            var table = document.getElementById(tableID);

            var rowCount = table.rows.length;
            var row = table.insertRow(rowCount);

            var cell1 = row.insertCell(0);
            var element1 = document.createElement("input");
            element1.type = "checkbox";
            element1.name="chkbox[]";
            cell1.appendChild(element1);

            var cell2 = row.insertCell(1);
            cell2.innerHTML = rowCount + 1;

            var cell3 = row.insertCell(2);
            var element2 = document.createElement("input");
            element2.type = "text";
            element2.name = "txtbox[]";
            cell3.appendChild(element2);


        }

        function deleteRow(tableID) {
            try {
            var table = document.getElementById(tableID);
            var rowCount = table.rows.length;

            for(var i=0; i<rowCount; i++) {
                var row = table.rows[i];
                var chkbox = row.cells[0].childNodes[0];
                if(null != chkbox && true == chkbox.checked) {
                    table.deleteRow(i);
                    rowCount--;
                    i--;
                }


            }
            }catch(e) {
                alert(e);
            }
        }

您的代码是正确的，只是那里的变化不大

<TR>
  <TD><INPUT type="checkbox" name="chk"/></TD>
  <TD> 1 </TD>
  <TD> <INPUT type="text" name="<?php echo $i; ?>"/> </TD>
</TR>

用此代码替换

<TR>
  <TD><INPUT type="checkbox" name="chkbox[]"/></TD>
  <TD> 1 </TD>
  <TD> <INPUT type="text" name="txtbox[]"/> </TD>
</TR>

你的工作完成了

var rows=getElementsByTagName("tr");
var noOfRows=rows.length;

for(int i=0;i<noOfRows;i++){

   var html=rows[i].innerhtml; /*a single row's inner html say (<td>apple</td><td>25</td>)*/
   var td=html.match(/(?!<td>)([\s*\w*]*)[^<\/td>]/g);     
   /**
         td[0] is 'apple', td[1] is '25'
   **/  

}
