将数据从视图传递到ASP.NET MVC4剃须刀中的控制器

Question

I've situation like, I've got two different views and one common controller (and its method too) for both. One is create item view and another is edit item view. My controller has one method called details. Now I want to inform controller that I'm coming form create or edit. On this basis my whole code will execute.

csHTML

<a href="..\example\details" id="iCreate">Create</a>
<script>
$( document ).ready(function() {
 $('#iCreate').click(function(){ 
    @Session["createMode"] = true; // Not working...
    @ViewBag["createMode"] = true; // Not working...
 });
});
</script>

Controller

public ActionResult details()
{
    // How to get data here??? 
     if(createMode){
      }
      else{
      }
}

To achieve this one way is pass parameter in querystring , but I don't want to do that. So is there any other way to pass data from View to Controller??

Thanks in advance...

Answer 1

regarding

@Session["createMode"] = true; // Not working...
@ViewBag["createMode"] = true; // Not working...

This cannot work because @Session and @ViewBag are server side variables which cannot be changed via JavaScript (which is client side) obviously.

You can use

1. Query string (which you mentioned)
2. Post form data
3. Use Ajax request and write a controller action which retrieves your request

to achieve what you want

Answer 2

do something like this

in HTML

<input type="hidden" id="createMode" value="False" />

javascript:

$( document ).ready(function() {
 $('#iCreate').click(function(){ 
    $('#createMode').val('True');
 });
});

Controller:

public void details(bool createMode)
{
    //createMode will automatically be passed
     if(createMode){
      }
      else{
      }
}

Answer 3

An easy way to do this is by using Ajax

$( document ).ready(function() {
 $('#iCreate').click(function(){ 
    $.ajax({
      url: '@Url.Action("details")' + '?mode=create'
    }).done(function(){
      //do something
    });
 });

public void details(string mode)
{
     if(mode.Equals("create")){
      }
      else{
      }
}
