我是MVC4的新手.我必须创建一个登录名验证.写完一个字符串后,当我们退出文本框时,它应该显示它是否可用.
查看代码是:
@{
ViewBag.Title = "Home Page";
}
@section featured {
<section class="featured">
<div class="content-wrapper">
@Html.TextBox("textbox1")
@Html.TextBox("txtTest")
</div>
</section>
}
@section scripts{
<script type="text/javascript">
$(document).ready(function(){
$('#textbox1').blur(function(){
alert("a");
});
});
</script>
}
现在代替alert("a"),我将不得不称之为行动.该操作将包含数据库检查.
控制器代码:
public class HomeController : Controller
{
public ActionResult Index()
{
ViewBag.Message = "Modify this template to jump-start your ASP.NET MVC application.";
return View();
}
public ActionResult SearchUser()
{
string ExistsCheck;
SqlConnection con = new SqlConnection(ConfigurationManager.AppSettings["conn"].ToString());
SqlDataAdapter da = new SqlDataAdapter();
SqlCommand cmd = new SqlCommand(); …我正在使用 NAudio 录制和播放音频文件。现在，我想在给定的持续时间内在音频文件中添加静音或蜂鸣声。您能否建议 NAudio 提供商名称以实现它？
我在页面中有一个文本框.从服务器端将可见性设置为false.现在我想通过使用java-script从客户端看到它.(在这种情况下,无法执行任何回发或部分回发.)
<%@ Page Title="Home Page" Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head id="Head1" runat="server">
<title>ControlVisibilityClientSide</title>
<script type="text/javascript">
function toggleVisibility(controlId)
{
var control = document.getElementById(controlId);
if(control.style.visibility == "visible" || control.style.visibility == "")
control.style.visibility = "hidden";
else
control.style.visibility = "visible";
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<input type="button" ID="btnShowHide" value="Show/Hide" onclick="toggleVisibility('TextBox1');" />
</div>
</form>
</body>
</html>
这工作正常.
但是当我使用时
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using …我有一个.aspx页面,其中包含两个按钮,一个是"btnCancel",另一个是"btnSave".
<asp:Button ID="btnCancel" runat="server" Text="Cancel" CssClass="Button" OnClick="btnCancel_Click" />
<asp:Button ID="btnSave" runat="server" Text="Save" CssClass="Button" OnClick="btnSave_Click"
OnClientClick="tinyMCE.triggerSave(false,true);" ValidationGroup="grp"/>
现在问题是在填满该页面中存在的一些文本框之后,如果我按下"输入按钮",则"btnCancel_Click"事件正在触发而不是"btnSave_Click".
任何人都可以建议我如何设置"btnSave_Click"按钮作为默认按钮.因此,如果任何人按下"输入按钮",它将触发"btnSave_Click"事件.
请帮忙.
更新的问题:
<asp:Panel DefaultButton="btnSave" runat="server" ID="pnlTest">
<asp:Button ID="btnCancel" runat="server" Text="Cancel" CssClass="Button" OnClick="btnCancel_Click" />
<asp:Button ID="btnSave" runat="server" Text="Save" CssClass="Button" OnClick="btnSave_Click"
OnClientClick="tinyMCE.triggerSave(false,true);" ValidationGroup="grp" />
</asp:Panel>
我在使用JavaScript只读字段时遇到问题.我有一个文本框,我正在阅读.
if(val == true)
{
ddlCnt.value=objRec.iCntId;
tAdd1.value=objRec.sAddress1;
tAdd2.value=objRec.sAddress2;
tCity.value=objRec.sCity;
tState.value=objRec.sState;
tZip.value=objRec.sZip;
//tAdd1.disabled = tAdd2.disabled = tCity.disabled = tState.disabled = tZip.disabled = ddlCnt.disabled = true;
//tAdd1.disabled = tAdd2.disabled = tCity.disabled = tState.disabled = tZip.disabled = ddlCnt.disabled = true;
tAdd1.setAttribute("readonly", true);
tAdd2.setAttribute("readonly", true);
tCity.setAttribute("readonly", true);
tState.setAttribute("readonly", true);
tZip.setAttribute("readonly", true);
}
它工作正常.现在停用我使用的这个只读属性
else
{
tAdd1.value = tAdd2.value = tCity.value = tState.value = tZip.value = "";
//tAdd1.disabled = tAdd2.disabled = tCity.disabled = tState.disabled = tZip.disabled = ddlCnt.disabled = false;
ddlCnt.value="-1";
vsRec.innerHTML='';
tAdd1.setAttribute("readonly", false);
tAdd2.setAttribute("readonly", …
