You can pass the model data into the java script file in these ways (1). Just set the value in hidden field and access the value of hidden field in java script. (2). And pass the value using function parameter. (3).
您可以通过以下方式将模型数据传递到 java 脚本文件中 (1)。只需在隐藏字段中设置值并在java脚本中访问隐藏字段的值。(2). 并使用函数参数传递值。(3).
var LoginResourceKeyCollection = {
UserName_Required: '<%= Model.UserName%>',
Password_Required: '<%= Model.Password%>'
}
</script>

It generally works this way, you just have to omit the ""otherwise it gets interpreted as string. So you can write something like that in your JS:
它通常以这种方式工作，您只需要省略""否则它会被解释为字符串。所以你可以在你的 JS 中写这样的东西：
var myinteger = @item.ID;
which renders as
呈现为
var myinteger = 123; //for example
Edit: This makes sense when you id is an integer, of course, for strings you need to encapsulate it in ''or "". And don't get annoyed by any syntax errors reported by intellisense, it seems to have a problem with that but it works out just nicely.
编辑：当您 id 是整数时，这是有道理的，当然，对于字符串，您需要将其封装在''or 中""。并且不要对智能感知报告的任何语法错误感到恼火，它似乎有问题，但效果很好。

Try this...mind single quotes on parameter value while calling js function
试试这个...在调用 js 函数时注意参数值上的单引号
function MyJsFunction(modelvalue)
{
alert("your model value: " + modelvalue);
}
<input type="button" onclick="MyJsFunction('@item.ID')" />
OR
<input type="button" onclick="MyJsFunction('@(item.ID)')" />

The best solution is pass your textbox ID to javascrpit function and then in function retrieve the value form the ID,
最好的解决方案是将您的文本框 ID 传递给 javascrpit 函数，然后在函数中从 ID 中检索值，
@Html.TextBoxFor(model => model.DatemailedStart, new {id = "MailStartDate", placeholder = "MM/DD/YYYY", maxlength = "40", @class = "TextboxDates", @onblur = "isValidDate('MailStartDate');" })
function isValidDate(id) {
var dateString = $('#'+id+'').val();
}
