It should be the property name, which is OperationNo.
它应该是属性名称，即OperationNo.
So your JS will be

document.getElementById("OperationNo").html = " Some text " ;
You can use the web inspector in Chrome or JS to view the html on your page to see the element attributes.
您可以使用 Chrome 或 JS 中的 web 检查器查看页面上的 html 以查看元素属性。

This is happens in a scenario of using same input fields with same properties in web form. Like the case of Login and Signup forms in single view/page. Previously it was like this
这是在 Web 表单中使用具有相同属性的相同输入字段的情况下发生的。就像在单个视图/页面中登录和注册表单的情况一样。以前是这样的
input one >
输入一个 >
<div class="field-wrap">
@Html.TextBoxFor(model => model.Username, new { @class = "form-control",placeholder = "Username", @required = "required", autofocus = "" })
@Html.ValidationMessageFor(model => model.Username, "", new { @class = "text-danger" })
</div>
input two>
输入二>
<div class="field-wrap">
@Html.TextBoxFor(model => model.Username, new { @class = "form-control", placeholder = "Username", @required = "required", autofocus = "" })
@Html.ValidationMessageFor(model => model.Username, "", new { @class = "text-danger" })
</div>
then i added a unique id # for the username input
然后我为用户名输入添加了一个唯一的 id #
the new input one >
新输入一 >
<div class="field-wrap">
@Html.TextBoxFor(model => model.Username, new { @class = "form-control", id = "loginUsername", placeholder = "Username", @required = "required", autofocus = "" })
@Html.ValidationMessageFor(model => model.Username, "", new { @class = "text-danger" })
</div>
the new input two >
新输入二 >
<div class="field-wrap">
@Html.TextBoxFor(model => model.Username, new { @class = "form-control", id = "SignupUsername" , placeholder = "Username", @required = "required", autofocus = "" })
@Html.ValidationMessageFor(model => model.Username, "", new { @class = "text-danger" })
</div>
