.NET / jquery - previewing a form result/rendering a view to a string
Here's the situation (using MVC 2.0):
I'm trying to build a feature to allow a user to preview changes they make to their bio/profile without actually committing their changes first. User fills out a form, clicks a "Preview" button and see what their changes look like. One difficulty is the front-end has a different master-page, so we need to render the whole view, not just a control.
Here's the approach I took:
- Asynch post the serialized form to a controller action
- Manipulate the model to flesh out the collections, etc. that don't get posted
- Return the front-end view, passing it this modified model
- Catch the response to the asynch method, wrap it in an iframe and write that to a lightboxed div on the page
Code I'm using... Controller action (the BuildPreview method just alters the model slightly)
[HttpPost]
[Authorize]
public ActionResult PreviewProfile(PersonModel model)
{
return View("Person", PeopleService.BuildPreview(model));;
}
HTML/Jquery stuff:
<script type="text/javascript">
$(document).ready(function () {
$("#previewButton").click(function (e) {
$.post("/PreviewProfile", $("#bioForm").serialize(), function (response) {
$("#previewFrame").html(response);
$("#holdMyPreview").modal({
overlayClose: true,
escClose: true,
开发者_开发问答 autoResize: true,
}, "html");
});
});
});
The modal method is just a basic lightbox-esque thing.
Running into two problems:
- EDIT - removed this, I was accidentally pulling a child control
- The iframe isn't rendering the html (perhaps because it's not valid b/c it's missing html/body/head tags?). If I just drop the response direcltly into the div, without the iframe, it works... albiet with the wrong stylesheet. If I try to insert it into iframe it just treats it as an empty page, just the html, head and body tags show up.
Any thoughts?

PS: Tried this over at MSDN forums (http://forums.asp.net/t/1675995.aspx/1?Rendering+a+view+into+a+string+) and it didn't get anywhere, figured I'd see if SO has any brilliance.
so, just massage the response when you get it back, add the missing html/body/head
$.post("/PreviewProfile", $("#bioForm").serialize(), function (response) {
response = "<html><body>"+response+"</body></html>";
$("#previewFrame").html(response);
$("#holdMyPreview").modal({
overlayClose: true,
escClose: true,
autoResize: true,
}, "html");
});
加载中,请稍侯......
