I want to update model value in JavaScript as below but it is not working.

function updatePostID(val)

{

    @Model.addcomment.PostID = val;

}

in Razor view as shown below

foreach(var post in Model.Post)

{

    <br/>

    <b>Posted by :</b> @post.Username <br/>

    <span>@post.Content</span> <br/>

    if(Model.loginuser == Model.username)

    {

        @Html.TextAreaFor(model => model.addcomment.Content)

        <button type=submit onclick=updatePostID('@post.PostID');>Add Comment </button>

    }

}

Can anyone tell me how to assign model value in JavaScript?

This should work

function updatePostID(val)

{

    document.getElementById('PostID').value = val;



    //and probably call document.forms[0].submit();

}

Then have a hidden field or other control for the PostID

@Html.Hidden(PostID, Model.addcomment.PostID)

//OR

@Html.HiddenFor(model => model.addcomment.PostID)
