我目前有一种形式,可以添加新的条目使用JavaScript点击。但是,我想更改每个后续“附加”的ID:例如第一个tbody的id为“participant1”,但下一个会有“participant2”的id,第八个“participant8”等等。更改选择ID与循环
这里是我的主文件摘录:
<fieldset class="row2">
<legend>List of Participants</legend>
<p>
<input type="button" value="Add Participant" onclick="addRow('dataTable')" />
<input type="button" value="Clear Participants" onclick="deleteRow('dataTable')" />
<p>(All acions apply only to entries with check marked check boxes only.)</p>
</p>
<table id="dataTable" class="form" border="1">
<tbody>
<tr>
<p>
<td>
<input type="checkbox" required="required" name="chk[]" checked="checked" />
</td>
<td>
<div>Participant: </div>
<select name="participant1" id="participant1">
<option>Person A</option>
<option>Person B</option>
<option>Person C</option>
</select>
</td>
</p>
</tr>
</tbody>
</table>
<div class="clear"></div>
</fieldset>
,这里是什么我目前正在与我的JS文件尝试:
function addRow(tableID) {
var table = document.getElementById(tableID);
var rowCount = table.rows.length;
if (rowCount < 50) {
var row = table.insertRow(rowCount);
var colCount = table.rows[0].cells.length;
for (var i = 0; i < colCount; i++) {
var newcell = row.insertCell(i);
//newcell.id="participant"+ rowCount;
var cellBody = table.rows[0].cells[i].innerHTML;
newcell.innerHTML = replaceAll(cellBody, 'participant1', 'participant' + (rowCount + 1));
console.log(rowCount, newcell.innerHTML)
}
}
else {
alert("More than 50 Participants? Are you sure?");
}
}
function replaceAll(str, find, replace) {
var i = str.indexOf(find);
if (i > -1) {
str = str.replace(find, replace);
i = i + replace.length;
var st2 = str.substring(i);
if (st2.indexOf(find) > -1) {
str = str.substring(0, i) + replaceAll(st2, find, replace);
}
}
return str;
}
但这似乎只在一个参与者服用?
