You&#39;ve accidentally set &quot;Pause on Exceptions&quot; to all/uncaught exceptions.

Go to the &quot;Sources&quot; tab. At the top right hand side, toggle the button that looks like the pause symbol surrounded by a hexagon (button on the far right) until the color of the circle turns black to turn it off.

There are a couple of reasons for this:

 1. You&#39;ve toggled on the *Pause On Caught Exceptions* button. So, toggle it off.

 2. You&#39;ve toggled a line (or more) to be paused on exception. So, toggle it off.

If you were unfamiliar with the tools, it was likely that at some point while in the debugger you toggled a setting that was causing the debugger to stop the application.

I suggest you &quot;Disable all break points&quot;:

You have multiple Google Chrome browser tabs open for the same URL and developer toolbar.

In some other tab, you have set breakpoints which are showing up when you are debugging in the current tab.

Solution: Close the developer toolbar in the other tab or the tab itself.


For anyone that&#39;s searching why their chrome debugger is automatically jumping to sources tab on every page load, event though all of the breakpoints/pauses/etc have been disabled.

For me it was the `&quot;breakOnLoad&quot;: true` line in VS Code `launch.json` config.

I have a DataFrame object similar to this one:

           onset    length
    1      2.215    1.3
    2     23.107    1.3
    3     41.815    1.3
    4     61.606    1.3
    ...

What I would like to do is insert a row at a position specified by some index value and update the following indices accordingly. E.g.:

           onset    length
    1      2.215    1.3
    2     23.107    1.3
    3     30.000    1.3  # new row
    4     41.815    1.3
    5     61.606    1.3
    ...

What would be the best way to do this?

I&#39;m surprisingly struggling to find a very simple example of how to add a marker(s) to a Google Map when a user left clicks on the map.

I have looked around for the past couple of hours, and consulted the Google Maps API documentation, and would appreciate some help!

If the debugging window is open, the debugger starts hitting lines by itself even though there are no set breakpoints.

I have tried using the &quot;Deactivate breakpoints&quot; button and it doesn&#39;t make a difference if it is on or off.

This happens on any website.




How can I stop Chrome from going into debug mode?

If the debugging window is open, the debugger starts hitting lines by itself even though there are no set breakpoints.
I have tried using the "Deactivate breakpoints" button and it doesn't make a difference if it is on or off.
This happens on any website.

In both the cases I get in output the content of the object:
 
    alert(JSON.stringify(obj));

or

    alert(obj.toString());

so... what&#39;s the difference? what are the advantages or disadvantages of each one?

Are there practical examples to show the difference?

Although the [size of localStorage](https://stackoverflow.com/questions/2989284) has been addressed in detail and there is a [online test for it](http://arty.name/localstorage.html), I was wondering what the maximum size of [sessionStorage](https://developer.mozilla.org/en-US/docs/DOM/Storage#sessionStorage) is for the common browsers?

I am Javascript beginner.

I am initing web page via the `window.onload`, I have to find bunch of elements by their class name (`slide`) and redistribute them into different nodes based on some logic. I have function `Distribute(element)` which takes an element as input and does the distribution. I want to do something like this (as outlined for example [here][1] or [here][2]):

    var slides = getElementsByClassName(&quot;slide&quot;);
    for(var i = 0; i &lt; slides.length; i++)
    {
       Distribute(slides[i]);
    }

however this does not do the magic for me, because `getElementsByClassName` does not actually return array, but a [`NodeList`][3], which is... 

**...this is my speculation...**

...being changed inside function `Distribute` (the DOM tree is being changed inside this function, and cloning of certain nodes happen). `For-each` loop structure does not help either.

The variable slides act&#39;s really un-deterministicaly, through every iteration it changes it&#39;s length and order of elements wildly.


What is the correct way to iterate through NodeList in my case? I was thinking about filling some temporary array, but am not sure how to do that...

**EDIT:**
---------

 

important fact I forgot to mention is that there might be one slide inside another, this is actually what changes the `slides` variable as I have just found out thanks to user [Alohci][4].

The solution for me was to clone each element into an array first and pass the array ono-by-one into `Distribute()` afterwards.

How to correctly iterate through getElementsByClassName

Is there any difference between `typeof (myVariable)` compared to `typeof myVariable`? 

Both work, but coming from PHP, I don&#39;t understand why this function can use parenthesis or not. 



Why does &quot;typeof&quot; not need parentheses?

I&#39;m trying to figure out a way to pass a native object through javascript&#39;s event.dataTransfer for drag and drop. I&#39;m writing the front end editor portion of a CMS, and want users to be able to drag and drop elements (of many different types, ranging from files to images to snippets of HTML to just about anything). That&#39;s why I want to pass a real object, so I can attach data to it to specify things that will be necessary in order to know how to render it.

One workaround is to use jQuery&#39;s .data() to attach an object to something else on the page, and then simply pass the selector string in setData... but I don&#39;t particularly enjoy that hack.

This could also be solved with jQuery UI&#39;s draggable/droppable (and I&#39;m not totally opposed to using any libraries), but since the dropzone is in an iframe, this is a actually a documented bug in the latest jQuery UI (1.10.2). Also, I would strongly prefer to do it natively if possible. There are already enough libraries in this app.

Here&#39;s the problem: http://jsfiddle.net/AHnh8/
    
    var foo = {foo: &quot;foo&quot;, bar: &quot;bar&quot;};

    $dragme.on(&quot;dragstart&quot;, function(e) {
        e.originalEvent.dataTransfer.setData(&quot;foo&quot;, foo);
    });

    $dropzone.on(&quot;dragenter&quot;, function(e) { e.preventDefault(); });
    $dropzone.on(&quot;dragover&quot;, function(e) { e.preventDefault(); });
    $dropzone.on(&quot;drop&quot;, function(e) {
        console.log(e.originalEvent.dataTransfer.getData(&quot;foo&quot;)); // [Object object]
        console.log(typeof e.originalEvent.dataTransfer.getData(&quot;foo&quot;)); // string
    });


Now, after reading the specs, I totally understand why this fails. What I don&#39;t understand, is how to ultimately achieve what I want.

Thanks

The [last example of jQuery&#39;s `focus()` documentation][1] states

    $(&#39;#id&#39;).focus()

should make the input focused (active). I can&#39;t seem to get this working.

Even in the console on this site, I&#39;m trying it for the search box

    $(&#39;input[name=&quot;q&quot;]&#39;).focus()

and I&#39;m getting nothing. Any ideas?

Is there a Java &#39;finally&#39; analogue in jQuery AJAX calls? I have this code here. In my **always** I throw an exception, however I ALWAYS want it to go to the **then()** method.


        call.xmlHttpReq = $.ajax({
            url : url,
            dataType : &#39;json&#39;,
            type : &#39;GET&#39;
        }).always(function(processedDataOrXHRWrapper, textStatus, xhrWrapperOrErrorThrown) {

           throw &quot;something&quot;;

        }).then(function() {

            alert(&quot;i want to always run no matter what&quot;);
        });


I have tried to use **done()**, **complete()**, and the another **always()**, but nothing seems to work.

When I evaluate an expression directly in the Chrome Console like 

    1 + 1
then I can reference to the evaluated value using 

    $_
![enter image description here][1]

However, I can&#39;t access the value with $_, when the value is a result of a console.log, coming from inside of my application, instead of an expression I typed directly into the console.

![enter image description here][2]

Is there a way to access the last evaluated expression, regardless where it came from?

I have struggled around with the heap profiler in chrome but it is very confusing. Especially if there are minimized libraries inside. But even the DOMElements views, elements which may not be removed are very unclear presented.

Are there any tips how to use the heap dump in chrome to find JS code that leads to memory leaks, code that cannot be cleaned by GC... and how to find elements messing around even if removed from dom?

In other words, how to read heap dump in chrome correctly? Dominators View? Comparison?

I&#39;m trying to test out my fallback page in my html5 cache manifest. I&#39;d rather not have to actually disconnect from the internet in order to do it. I&#39;ve heard that it doesn&#39;t work quite right in Chrome, so I need to test it specifically. Does Chrome have the ability to work offline? I&#39;ve searched through the settings and the available extensions, and I can&#39;t find anything.

I am trying to understand the working of Google chrome extensions. I was studying the `manifest.json` file where I came across the permissions `&quot;http://*/*&quot;`, `&quot;https://*/*&quot;` and `&quot;&lt;all_urls&gt;&quot;`
