我试图将具有相同名称的文本框的值从JSP传递到servlet,但无法完成此任务。
我尝试在servlet中使用它,但只得到一个文本框值:
String[] words = request.getParameterValues("words"); String[] meanings = request.getParameterValues("meaning");
我的JavaScript可以帮助生成多个表格行:
<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"; cell1.appendChild(element1); var cell2 = row.insertCell(1); var element2 = document.createElement("input"); element2.type = "text"; cell2.appendChild(element2); var cell3 = row.insertCell(2); var element3 = document.createElement("input"); element3.type = "text"; cell3.appendChild(element3); } 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); } } </SCRIPT>
HTML表格会产生多行:
</body> <form name="managelist" action="../createlistpath" method="post"> <TABLE id="dataTable" width="600px" border="0"> <tr> <td><b> List Name</b></td> <td colspan="2"><input type="text" name="listname"></td> </tr> <tr > <td><b>Select</b></td> <td><b>Word</b></td> <td><b>Meaning</b></td> </tr> <TR > <TD><INPUT type="checkbox" name="checkbox"/></TD> <TD> <INPUT type="text" name="words" /> </TD> <TD> <INPUT type="text" name="meaning" /> </TD> </TR> </TABLE> <INPUT type="button" value="Add Row" onclick="addRow('dataTable')" /> <INPUT type="button" value="Delete Row" onclick="deleteRow('dataTable')" /> <br> <input type="submit" value = "submit" name="submit"> </form> </body>
您不命名动态创建的输入元素(命名为“单词”或“含义”)
var element2 = document.createElement("input"); element2.name = "words"; element2.type = "text"; cell2.appendChild(element2);
