datalist里，有两个控件，先在想通过一个checkbox激发一个js事件，对比这两个控件的值，如果一样的话，背景不变，如果不一样，背景都变成红色<td style="border: 1px solid #C0C0C0; width: 40%; " id="td13" runat="server">
<asp:TextBox ID="TextBox1" runat="server" BorderStyle="None" Width="100%" ></asp:TextBox>
<asp:Label ID="Label1" runat="server" Text='<%#Eval("aaa")%>' Width="100%" ></asp:Label>
</td>其中textbox1可以由用户输入，label1的值已经从数据库中读取出来，请问怎么写这个js？
<asp:TextBox ID="TextBox1" runat="server" BorderStyle="None" Width="100%" ></asp:TextBox>
<asp:Label ID="Label1" runat="server" Text='<%#Eval("aaa")%>' Width="100%" ></asp:Label>
</td>其中textbox1可以由用户输入，label1的值已经从数据库中读取出来，请问怎么写这个js？
<script type="text/javascript">
function a() {
var datalist = document.getElementById("dgrid");
var name="";
for (var i = 1; i < datalist.rows.length; i++) {
name += datalist.rows[i].cells[0].innerText;
}
alert(name);
}
</script>
var txt= gv.getElementsByTagName("input");
for(var i=0;i<txt.length;i++)
{
}
var Array1s = document.getElementById("datalist1");
var textbox1values = document.getElementById("<%= TextBox1.ClientID %>").value;
var lbl1values = document.getElementById("<%= Label1.ClientID %>").value;
if(textbox1values != lbl1values )
{
document.getElementById("<%= TextBox1.ClientID %>").style.color = "Red";
document.getElementById("<%= Label1.ClientID %>").style.color = "Red";
} 试试行不行
<script type="text/javascript">
function a() {
var datalist = document.getElementById("dgrid");
for (var i = 1; i < datalist.rows.length; i++) {
if (datalist.rows[i].cells[2].innerText == datalist.rows[i].cells[7].innerText) {
datalist.rows.style.backgroundColor = "red";
}
}
}
</script>
var Array1s = document.getElementById("datalist1");
起什么作用，报错是找到textbox1和label1啊，他们在datalist1里面，能这个取到他们的值吗？
datalist不循环能拿到里面的值？
我这两个控件在同一列里
这一句注释掉，不用。 <script type="text/javascript" language="javascript">
function setstyle()
{
var textbox1values = document.getElementById("<%= TextBox1.ClientID %>").value;
var lbl1values = document.getElementById("<%= Label1.ClientID %>").value;
if(textbox1values != lbl1values )
{
document.getElementById("<%= TextBox1.ClientID %>").style.color = "Red";
document.getElementById("<%= Label1.ClientID %>").style.color = "Red";
}
}
</script>checkbox激发的js事件里调用setstyle方法即可
只是给你说说实现方法，你可以按照这样的方法去试试，你说的没有cells属性你自己百度下datalist是什么

function ReSize() {
var table_all = document.getElementById("table_all");

var td99 = document.getElementById("td99");
td99.style.height = table_height - 28 + "px";

这两个右键看看生成的html是什么
