急求哪位大神帮我解决这个问题，其实挺容易，只是我不熟悉

[zj25810]

<script type="text/javascript">
function setVal() {

delCookie("BBSTitle");
addCookie("BBSTitle", document.getElementById("txt_title").value, 1);
delCookie("BBSCon");
addCookie("BBSCon", document.getElementById("content1").value, 1)
}
</script>

<asp:TextBox runat="server" ID="txt_title" style=" width:550px; border:1px solid #CCC; height:18px; padding-left:3px; padding-top:5px; font-family:新宋体; color:#999; font-weight:bold;"></asp:TextBox>
<asp:Label ID="Label1" runat="server" Text="">
<textarea id="content1" onblur="setVal(obj)" runat="server" cols="100" rows="8" style="width:780px;height:420px;visibility:hidden;" ></textarea>
</asp:Label>

我可以获得BBSTitle的值，但是BBSCon一直为空。这是为什么？

[游北亮]

document.getElementById("content1").value能取到内容吗？
alert(document.getElementById("content1").value)试试

[zj25810]

不能，要是有这么容易我也就不来论坛问了。

[仲兴轩]

<textarea id="content1" name="content1">

加name, 用 document.forms[0].content1.value

[仲兴轩]

外面要加个<form>

[p2227]

是用.value获取的，你获取不了应该是有另外一个元素的id也是这个，冲突了。或者是其他原因冲突了。比如下面的代码是ok的，在textarea输入 的东西是可以alert出来

<textarea rows="10" cols="50" id="t" value=""></textarea>
<input type="button" onclick="r()" value="显示textarea的值"/>
<script>
r = function(){
	alert(document.getElementById("t").value)
}
</script>

[三石-gary]

delCookie("BBSTitle");
addCookie("BBSTitle", document.getElementById("txt_title").value, 1);
你把这个去掉看能不能获得BBSCon的值。。

[zj25810]

不能，我用了最平常的 var s=document.getElementById("content1").value;单独测试过，也没有值

[三石-gary]

document.getElementById( "content1").Inner.Text 试试这个

[zj25810]

document.getElementById(...).Inner.Text' 为空或不是对象

[三石-gary]

document.all.content1.value 试试这个

[hellNo]

ASP控件runat="server"后控件ID会变的，你document.getElementById("content1") 这样能获取到吗?你运行以后看看控件ID获取的对吗？不知道是不是这个原因

[三石-gary]

document.all.content1.value

[zj25810]

我现在是需要document.getElementById("<%=content1.ClientID %>").value
还是document.getElementById("<%=Label1.ClientID %>").value
还是怎么样？

[zj25810]

我发现两个都取不到<textarea></textarea>里面的值。

[zj25810]

我第一个那个 runat="server" 删掉了取到了值，第二个我在后台用
protected void btnLook_Click(object sender, EventArgs e)
{
string Content = content1.Value;
ClientScript.RegisterClientScriptBlock(this.GetType(), "", "setVal('" +Content + "')", true);
}取到的值

divStock.innerHTML = str;

[hch126163]

右键，查看源代码，看看你的控件的ID是什么？

[Quote=引用 9 楼 zj25810 的回复:]

我现在是需要document.getElementById("<%=content1.ClientID %>").value
还是document.getElementById("<%=Label1.ClientID %>").value
还是怎么样？
[/Quote]

[zj25810]

我用后台拿值解决了这个问题。因为JS取<textarea></textarea>里面的值很繁琐。

[xue_howar]

貌似在<asp:Label>标签里的<textarea></textarea> 不能输入值，又怎么获取呢 ？ 也看不出你的第一个值是怎么会获取的。还有既然是server控件，就需要用document.getElementById("<%=content1.ClientID %>")获取值吧。
