将以前的行数据添加到动态生成的行 [英] add previous row data to dynamically generated row
本文介绍了将以前的行数据添加到动态生成的行的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想要做的是，我在第一行中写入的数据应该被复制到生成的行中。
这是我的表和Java脚本。
< form>
< table border =1id =engagementments>
< tr>
< th>< input type =checkboxonclick =checkAll（this）>< / th>
< th>组织< / th>
< th> Project< / th>
< th>产品< / th>
< th>活动< / th>
< / tr>
< tr>
< td>< input type =checkboxonclick =checkAll（this）>< / td>
< td>< input type =text/>< / td>
< td>< input type =text/>< / td>
< td>< input type =text/>< / td>
< td>< input type =text/>< / td>
<！ -
< td>< input type =text/>< / td>
< td>< input type =text/>< / td>
< td>< input type =text/>< / td>
< td>< input type =text/>< / td>
< td>< input type =text/>< / td>
- >
< / tr>
< / table>
< option value =>添加更多与上述相同数据的行< / option>
< option value =1> 1更多< / option>
< option value =2> 2更多< / option>
< option value =3> 3更多< / option>
< option value =4> 4更多< / option>
< option value =5> 5更多< / option>
< / select>
< / form>
< script language =javascript>
函数addrow（tableID）
{
var table = document.getElementById（tableID）;
var rowCount = table.rows.length;
var row = table.insertRow（rowCount）;
var colCount = table.rows [0] .cells.length;
var e = document.getElementById（mode）;
var strUser = e.options [e.selectedIndex] .value; （var i = 0; i
$ b（var j = 0; j
var newcell = row.insertCell（i）;
newcell.innerHTML = table.rows [1] .cells [i] .innerHTML;
}
var row = table.insertRow（rowCount）;
}
}
< / script>
解决方案
如果您已经在使用jQuery， -
$ b $
$（＃mode）。on（'change'，function（）{
var rows = parseInt（this.value）;
var lastRow;
for（var i = 0; i
$（'＃engagements tr'）。last（）。after（lastRow）;
}
}）;

I have a table. onchange of select variable, it generates rows. what i want to do is that, the data which i wrote in the first row, should be copied in the generated rows. This is my Table and the java script.
<form>
<table border = "1" id = "engagements">
<tr>
<th><input type="checkbox" onclick="checkAll(this)"></th>
<th>Organization</th>
<th>Project</th>
<th>Product</th>
<th>Activity</th>
</tr>
<tr>
<td><input type="checkbox" onclick="checkAll(this)"></td>
<td><input type = "text"/></td>
<td><input type = "text"/></td>
<td><input type = "text"/></td>
<td><input type = "text"/></td>
<!--
<td><input type = "text"/></td>
<td><input type = "text"/></td>
<td><input type = "text"/></td>
<td><input type = "text"/></td>
<td><input type = "text"/></td>
-->
</tr>
</table>
<select name = "mode" id = "mode" onchange="addrow('engagements')">
<option value="">Add More Rows with Same Data as Above</option>
<option value="1">1 More</option>
<option value="2">2 More</option>
<option value="3">3 More</option>
<option value="4">4 More</option>
<option value="5">5 More</option>
</select>
</form>
<script language="javascript">
function addrow(tableID)
{
var table = document.getElementById(tableID);
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);
var colCount = table.rows[0].cells.length;
var e = document.getElementById("mode");
var strUser = e.options[e.selectedIndex].value;
for (var j = 0; j < strUser; j++)
{
for (var i = 0; i < colCount; i++)
{
var newcell = row.insertCell(i);
newcell.innerHTML = table.rows[1].cells[i].innerHTML;
}
var row = table.insertRow(rowCount);
}
}
</script>
解决方案
If you are already using jQuery , You can do this -
$("#mode").on('change', function () {
var rows = parseInt(this.value);
var lastRow;
for (var i = 0; i < rows; i++) {
lastRow = $('#engagements tr').last().clone();
$('#engagements tr').last().after(lastRow);
}
});
