值的隐藏字段设置不是在文件准备功能体现 [英] Value set in the hidden field is not reflecting in document ready function

问题描述

我无法从隐藏字段检索值。有时候，我得到的值和放大器;有时它的到来为空。请协助。

也让我知道，我们可以存储一个C＃的ArrayList在hiddenfield？
我的HTML看起来像这样...

 ＆LT;输入类型=隐藏ID =hdnSelectedContactIDVALUE =@ Model.Contact.ContactID/＆GT;
＆LT;输入类型=隐藏ID =hdnSelectedAddressListVALUE =@ Model.Contact.AddressList/＆GT;
$（文件）。就绪（函数（）{
        _contactID = $（＃hdnSelectedContactID）VAL（）。
        。_addressList = $（＃hdnSelectedAddressList）VAL（）;
}
 

在的document.ready方法分配一个名称，它之后，外部HTML（快速腕表）出现这样的...

  outerHTML＆LT;输入ID = hdnSelectedContactID类型=隐藏的名称= hdnSelectedContactID＆gt;中串outerHTML＆LT;输入ID = hdnSelectedAddressList值= Dell.USP.Business.Models.TelephoneList类型=隐藏的名称= hdnSelectedAddressList＆gt;中串
 

解决方案

为什么不使用辅助插入一个隐藏字段？

  @ Html.HiddenFor（H =＆GT; h.ContactID）
 

您不能存储在hiddenfield作为一个对象的ArrayList，但你可以在分隔符单独他们hiddenfield插入一个ArrayList的值。你把它变成一个字符串，并在视图中加载它。

I am not able to retrieve the values from hidden field. Sometimes I am getting values & sometimes its coming empty. Please assist.

Also let me know can we store a C# arraylist in a hiddenfield? My HTML looks like this...

<input type="hidden" id="hdnSelectedContactID" value="@Model.Contact.ContactID" />
<input type="hidden" id="hdnSelectedAddressList" value="@Model.Contact.AddressList" />


$(document).ready(function () {
        _contactID = $("#hdnSelectedContactID").val();
        _addressList = $("#hdnSelectedAddressList").val();
}

After assigning a name to it in document.ready method, the outer html(in quick watch) appears like this...

outerHTML         "<INPUT id=hdnSelectedContactID type=hidden name=hdnSelectedContactID>"            String

outerHTML         "<INPUT id=hdnSelectedAddressList value=Dell.USP.Business.Models.TelephoneList type=hidden name=hdnSelectedAddressList>"       String

解决方案

Why not use a helper to insert a hidden field?

@Html.HiddenFor(h => h.ContactID)

You can't store an arraylist in a hiddenfield as an object, but you can insert the values of an arraylist in a hiddenfield with delimiters to seperate them. You turn it into a string and load it in the view.
