[英]Mvc4 display model property in View
I have developed one module and it works fine. 我已经开发了一个模块,它工作正常。 I have few textboxes and submit button. 我有几个文本框和提交按钮。 When submitting textboxes values i will compare those with db values and return result and display. 提交文本框值时,我将比较它们与db值,并返回结果并显示。 I have used paging also. 我也用过分页。 This is my action method. 这是我的动作方法。
[HttpGet]
public ActionResult Index(int? clientId, DateTime? dateofAction, int? doc_typeid, string employeeID,string citizenId,int? currentFilter, DateTime? filterdateTime,int? filterdocType,string filteredemployeeID,string filteredcitizenId,int? page)
{
logDetailsEnumeration model = new logDetailsEnumeration();
DB_KYC3Entities db = new DB_KYC3Entities();
var docTypes = from c in db.tm_doc_type select c;
if (clientId != null)
{
page = 1;
}
else
{
clientId = currentFilter;
}
if(dateofAction!=null)
{
page = 1;
}
else
{
dateofAction = filterdateTime;
}
if(doc_typeid != null)
{
page = 1;
}
else
{
doc_typeid = filterdocType;
}
if(employeeID!=null)
{
page = 1;
}
else
{
employeeID = filteredemployeeID;
}
if(citizenId!=null)
{
page = 1;
}
else
{
citizenId = filteredcitizenId;
}
ViewBag.CurrentFilter = clientId;
ViewBag.filterdateTime = dateofAction;
int pageSize = 8;
int pageNumber = (page ?? 1);
VerificationLogBAL obj = new VerificationLogBAL();
int docType = obj.GetDocDetails(doc_typeid?? default(int));
List<logDetails> logDetails = obj.getlogDetails(clientId?? default(int), dateofAction??DateTime.Now, docType, employeeID, citizenId);
IPagedList<logDetails> pagedLog = logDetails.ToPagedList(pageNumber, pageSize);
model = new logDetailsEnumeration()
{
doc_typeid= doc_typeid,
Count=logDetails.Count,
employeeID = employeeID,
citizenId= citizenId,
logDetails = pagedLog,
doctype_name=new SelectList(docTypes, "doc_typeid", "doctype_name")
};
return View("Index",model);
}
}
This is View 这是视图

}
Above code works fine. 上面的代码工作正常。 I have some difficulties. 我有些困难 Inside action method i have model. 内部动作方法我有模型。 Inside model i have Count=logDetails.Count. 在模型内部,我有Count = logDetails.Count。 Count will be holding number of rows returned. Count将保存返回的行数。 When the first time page loads the count value will be 0 and when there is no corresponding matching data in database then also count value will be 0. I want to display message something like below. 当第一次加载页面时,计数值将为0,而当数据库中没有相应的匹配数据时,计数值也将为0。我想显示以下消息。
var records = @Html.Raw(Model.Count);
if(records==0)
{
fun_toastr_notify('success','No Records Found');
}
It also works but it also pops up message when the page loads first time(count will be zero). 它也可以使用,但是在页面第一次加载时也会弹出消息(计数为零)。 May i know how can I avoid this? 我可以知道如何避免这种情况吗? Thanks in advance. 提前致谢。
have you tried something like that? 你尝试过类似的东西吗? (that code has been written on the fly, not tested) (该代码是即时编写的,未经测试)
<script type="javascript/text">
document.ready(function(){
@if (Model.logDetails.Count != 0)
{
fun_toastr_notify('success','No Records Found');
}
};
</script>
for the first time pass a viewbag.isfirsttime = true depending on search parameters or whatever you have to differentiate if it is first time. 第一次通过viewbag.isfirsttime = true取决于搜索参数,或者如果是第一次则需要区别。 than in code 比在代码中
<script>
@{
var count = !ViewBag.IsFirstTime ? Model.Count : -1;
};
var records = @count;
if (records == 0) {
fun_toastr_notify('success', 'No Records Found');
}
</script>
This will work surely. 这一定可以工作。 Happy Coding ! 编码愉快!
