如何在表单集合键值中获取列表框ID？ [英] How do I get list box id in my form collection key values?

问题描述

我正在提交给学生发放的书籍。因为我提交了一个列表框，用于为同一个学生发放多本书，当我提交表格时。在post方法中，我使用表单集合类从表单中检索所有值，当我检查表单集合键值时，它显示所有字段id但是列表框id没有显示在表单集合键中。



我尝试了什么：



这里是我用于显示列表框的代码

$（＃FieldListTable）。append（'

< input class =addNewButtonstyle =float：left; margin-left：0px; type =buttonvalue =添加id =btnAdd/>< input class =addNewButtonstyle =float：left; margin-left：0px;type =buttonid =btnRemove value =删除/>

BOOkS LISt @ Html.ListBox（LstSignInAuthority ，Enumerable.Empty< SelectListItem>（），new {@id =LstSignInAuthority，style =width：200px; height：130px;}）

' ）;

I am submitting books issued to students in form.for that i had kept one list box in that for issuing multiple books for same student,when i submit form. in post method i use form collection class to retrieve all values from form,when i check form collection key values it displays all fields id's but list box id is not showing in form collection key's.

What I have tried:

here the code which i used in view to display list box in the form
$("#FieldListTable").append('

<input class="addNewButton" style="float: left; margin-left: 0px;" type="button" value="Add" id="btnAdd" /><input class="addNewButton" style="float: left; margin-left: 0px;" type="button" id="btnRemove" value="Remove" />

BOOkS LISt @Html.ListBox("LstSignInAuthority", Enumerable.Empty<SelectListItem>(), new { @id = "LstSignInAuthority", style = "width:200px;height:130px;" })

');

解决方案

("#FieldListTable").append('

<input class="addNewButton" style="float: left; margin-left: 0px;" type="button" value="Add" id="btnAdd" /><input class="addNewButton" style="float: left; margin-left: 0px;" type="button" id="btnRemove" value="Remove" />

BOOkS LISt @Html.ListBox("LstSignInAuthority", Enumerable.Empty<SelectListItem>(), new { @id = "LstSignInAuthority", style = "width:200px;height:130px;" })

');
