无法在 asp.net c# 中保存可编辑 div 的 innerText/innerHTML
Can't save innerText / innerHTML of an editable div in asp.net c#
我尝试保存可编辑div的更改文本。我在页面加载时将一些文本放入 div 并在浏览器中更改它,但我无法保存更改,因为 innerHTML 内容没有更改。
这是我的 aspx 文件:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Title</title>
</head>
<body>
<form id="form1" runat="server">
<div contenteditable="true" runat="server" id="txtText" ></div>
<asp:Button ID="btnSave" runat="server" Text="Speichern" OnClick="btnSave_Click" />
</form>
</body>
</html>
这是文件背后的代码:
public partial class editWordModule : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
txtText.InnerHTML = "This is the unmodified text";
}
protected void btnSave_Click(object sender, EventArgs e)
{
string test = txtText.InnerHtml;
//still shows "This is the unmodified text" while it was changed before in the div
}
}
}
那么如何保存 div 的编辑后的 innerHTML?
用JavaScript做个小把戏。
单击按钮时,获取DIV的innerHTML并放入asp:HiddenField
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Title</title>
</head>
<body>
<script type="text/javascript">
function ChangeDiv() {
var div = document.getElementById("txtText");
var hdn = document.getElementById("hdnText");
hdn.value = div.innerHTML;
}
</script>
<form id="form1" runat="server">
<div contenteditable="true" id="txtText"></div>
<asp:HiddenField ID="hdnText" runat="server" ClientIDMode="Static" />
<asp:Button ID="btnSave" runat="server" Text="Speichern" OnClick="btnSave_Click" OnClientClick="ChangeDiv()" />
</form>
</body>
</html>
并在您的代码后面读取隐藏字段。
string hdn = hdnText.Value
