The below code should apply different CSS classes based on your Model&#39;s `CanEdit` Property value .

    &lt;div class=&quot;@(Model.CanEdit?&quot;visible-item&quot;:&quot;hidden-item&quot;)&quot;&gt;Some links&lt;/div&gt;

But if it is something important like Edit/Delete links, you shouldn&#39;t be simply hiding,because people can update the css class/HTML markup in their browser and get access to your important link. Instead you should be simply **not Rendering** the important stuff to the browser.

    @if(Model.CanEdit)
    {
      &lt;div&gt;Edit/Delete link goes here&lt;/div&gt;
    }



Try:

    &lt;div style=&quot;@(Model.booleanVariable ? &quot;display:block&quot; : &quot;display:none&quot;)&quot;&gt;Some links&lt;/div&gt;

Use the &quot;Display&quot; style attribute with your bool model attribute to define the div&#39;s visibility. 

Your code isn&#39;t working, because the hidden attibute is not supported in versions of [IE before v11][1]

If you need to support IE before version 11, add a CSS style to hide when the hidden attribute is present:

    *[hidden] { display: none; }


  [1]: https://developer.mozilla.org/en/docs/Web/HTML/Global_attributes/hidden

I know the question is specifically about hiding the div but if you don&#39;t do anything else with the div (in JavaScript for example) then you can just not include it in the output of the view by using the Razor `@if` syntax.

    @if (Model.IsOwnedByUser &amp;&amp; Model.CanEdit)
    {
    &lt;div&gt;Some Links&lt;/div&gt;
    }



I&#39;m trying to do a lescan using hcitool on the raspberry pi. 

The command prints out 

    Set scan parameters failed: Input/output error. 

I&#39;m not sure, what exactly happens here. My iPhone is advertising here. 

I&#39;m using a BLE dongle from IOGear. 

However, if I restart my machine, it shows the a MAC address after I issue the `lescan` command, and starts showing the same error after I issue the lescan command a couple of more times. Is it like, the lescan command cannot be issued more than once?

Note I have studied the [git-is-very-very-slow](https://stackoverflow.com/questions/3055506/git-is-very-very-slow) question, but in their case the reason was big binary files - while in my repository there is PHP/JS/HTML/CSS only code (no binaries) and the biggest file in the repository is around 800 KB.

I&#39;ve changed one file (a few lines), then `git add .` and `git commit -m &quot;msg&quot;`, then `git push origin master`.

On some other machine, when I do `git pull origin master` it downloads a few MiB of data, and it takes more than 2 minutes to calculate the delta and apply changes. Something is terribly wrong here.

I suspect some recent operations may cause this:

recently, I&#39;ve accidentally added many vendor assets (`bower_components` assets)
when I realized it, I&#39;ve used `git rm` to remove them from repository (and ofcourse, `git add`, `git commit` and `git push` to upstream).

That was a few days ago and the problems I have right now started happeing around that time.

I have two questions:

* Why this is happeing?
* How can I fix my repository?

Note: I am the only one useing and pushing to this repo.

Git pull is very slow... Why?

Here is what I have at the moment 

     hidden=&quot;@(Model.IsOwnedByUser||!Model.CanEdit)&quot;
This works fine on Chrome but doesnt hide on Internet Explorer

I tried also visibility set false but no luck.

then I found out another style as below 

    style=&quot;@(Model.IsOwnedByUser||!Model.CanEdit)?&#39;display:none&#39;&quot;&quot;

I could not get it worked. What is the correct format to hide an element with Razor syntax?

Or I would use Jquery to hide the element. but is it actually possible print out jquery statement that would hide the element on page load?

Does any one know how to do a simple image upload and display it on the page.

This is what I&#39;m looking for.

* The page will display the image without refreshing the page or going to another file.
* multiple `&lt;img src&gt;` will do because I need to display different image size.

So I&#39;ve got this HTML form:

    &lt;html&gt;
    &lt;head&gt;&lt;title&gt;test&lt;/title&gt;&lt;/head&gt;
    &lt;body&gt;
        &lt;form action=&quot;myurl&quot; method=&quot;POST&quot; name=&quot;myForm&quot;&gt;
            &lt;p&gt;&lt;label for=&quot;first_name&quot;&gt;First Name:&lt;/label&gt;
            &lt;input type=&quot;text&quot; name=&quot;first_name&quot; id=&quot;fname&quot;&gt;&lt;/p&gt;

    &lt;/html&gt;

Which would be the easiest way to send this form&#39;s data as a JSON object to my server when a user clicks on submit?

UPDATE: 
I&#39;ve gone as far as this but it doesn&#39;t seem to work:

    &lt;script type=&quot;text/javascript&quot;&gt;
        function submitform(){
            alert(&quot;Sending Json&quot;);
            var xhr = new XMLHttpRequest();
            xhr.open(form.method, form.action, true);
            xhr.setRequestHeader(&#39;Content-Type&#39;, &#39;application/json; charset=UTF-8&#39;);
            var j = {

            };
            xhr.send(JSON.stringify(j));

What am I doing wrong?

I did some javascript / jQuery programming a few years ago, and I just started up again. Back then the dollar sign was used for all the jQuery functionality, and if no jQuery library was imported, the dollar sign was not defined. 

Today, I started up Firefox, in a completely empty html file with no javascript libraries, and yet the dollar sign points to something. If I open the Firefox console and type **&#39;$&#39;** I get `&quot;function()&quot;`.

1) Is it correct that dollar sign was not assigned, a few years back, or do I remember wrong?

2) What is the **dollar sign**, if not jQuery?

How can I find an element&#39;s ancestor that is closest up the tree that has a particular class, **in pure JavaScript**? For example, in a tree like so:

    &lt;div class=&quot;far ancestor&quot;&gt;
        &lt;div class=&quot;near ancestor&quot;&gt;
            &lt;p&gt;Where am I?&lt;/p&gt;
        &lt;/div&gt;
    &lt;/div&gt;

Then I want `div.near.ancestor` if I try this on the `p` and search for `ancestor`.

I am using [EntityFramework.Extended](https://github.com/loresoft/EntityFramework.Extended) library to perform batch updates. The only problem is EF does not keep track of the batch updates performed by the library. So when I query the `DbContext` again it does not return the updated entities.

I found that using `AsNoTracking()` method while querying disables the tracking and gets fresh data from the database. However, since EF does not keep track of the entities queried with `AsNoTracking()`, I am not able to perform any update on the queried data.

Is there any way to force EF to get the latest data while tracking changes?

    var jsdata = @Html.Raw(Json.Encode(Model.data)); 

But I don&#39;t know why I should have to use JSON. 

Also while at the moment I&#39;m restricting this to 255 bytes. In the future it could run into many MBs.
