Obtaining Entire Model Objects from Form Data in MVC
When passing entire model objects through form data, it's essential to ensure their correct conversion back to the model type in the controller. Here's how to achieve this:
JavaScript Implementation:
Utilize FormData to serialize the entire model rather than manually appending individual properties:
var formdata = new FormData($('form').get(0));
This will also include any file inputs present in the form.
Ajax Request:
Post the form data using Ajax, disabling auto-processing and content type setting:
$.ajax({
url: '@Url.Action("YourActionName", "YourControllerName")',
type: 'POST',
data: formdata,
processData: false,
contentType: false,
});
Controller Action:
In the controller, define an action that accepts the model as a parameter:
[HttpPost]
public ActionResult YourActionName(YourModelType model)
{
// Perform operations on the model...
}
Alternatively, if the model contains a file input, the second parameter should be HttpPostedFileBase for the file property:
[HttpPost]
public ActionResult YourActionName(YourModelType model, HttpPostedFileBase myImage)
{
// Handle file and perform operations on the model...
}
Additional Data Appendage:
If required, additional properties can be appended to the form data using:
formdata.append('someProperty', 'SomeValue');The above is the detailed content of How to Pass Entire Model Objects via Form Data in MVC?. For more information, please follow other related articles on the PHP Chinese website!
