在上一个问题之后我继续回答：On Click - Make @Html.DisplayFor an editable text field
我想在JQuery中获取一个电影项目的ID，我只需要在＆＃34; var＆＃34;形式。
我目前可以通过文本框条目获取.Name，但我似乎无法使用此代码来获取ID。任何帮助表示赞赏！
查看摘录
@Html.HiddenFor(modelItem => item.ID) // <-- this is above it a bit
<span class="item-display">
<span style="font-size: 17px;">@Html.DisplayFor(modelItem => item.Name)</span>
</span>
<span class="item-field">
@Html.EditorFor(modelItem => item.Name)
</span>
这是让我获得项目字段值
的JQuery.on("focusout", "span.item-field", function (event) {
console.log("this is a log");
var $field = $(event.currentTarget),
$display = $field.prev("span.item-display");
$display.html($field.find(":input:first").val());
$display.show();
$field.hide();
var name1 = $field.find(":input:first").val(); // get's the .Name
我是JQuery的新手，所以我不确定这是否足以帮助解决我的问题。我非常乐意附上更多代码，我只是试图了解情况。
谢谢！

答案 0 :(得分：1)
var ID = $field.siblings("#ID").val();
或
var ID = $field.siblings("[name=ID]").val();
答案 1 :(得分：0)
可以使用此
var name1 = $field.find("[id$=Name]").val();
答案 2 :(得分：0)
我所做的是添加隐藏字段来存储我的ID
<span style="visibility:hidden">@Html.DisplayFor(modelItem => item.ID)</span>
然后我才导航到它。对于这个例子，我必须使用下面的代码，因为$this位于我当前位置之前的两个span中。
var id = $(this).prev("span").prev("span").text();
