Removing overlays

    "Overlays"....!!! What is this now! Never heard or used it before? You might immediately say "NO"...But, actually all of you have already seen what an overlay is and you have also used it! Now you would say "When!?!?" Well, all of the markers, polylines, polygons that you have created are overlays. Overlays are objects on the map that are tied to latitude/ longitude coordinates, so they move when you drag or zoom the map. Overlays reflect objects that you add to the map to designate points, lines, areas or collection of objects.

    Till now we have seen how to create an overlay. In today's example we will see how to remove an overlay. In this example we will create markers on click. But the difference will be that when you create a new marker, the earlier one will disappear from the map. So at any given time there would only be one single marker on the map! Note that removing the marker does not delete the overlay; it simply removes the overlay from the map.

    Let's head on to the example. You can copy the following code in a text file and save it with .html extension. Now click on this file and it will open up in your default browser and you will see the map in action!


    The code is very simple. You should have no problems in understanding the same. If you have any queries or doubts regarding the code, you can leave a comment or drop me a mail. The output of the above example is as seen in the result section above.

Difference between word-break: break-all versus word-wrap: break-word

The 2 CSS properties word-break: break-all and word-wrap: break-word appear to work in the same way or generate the same output, but there is a slight difference between the 2 and we will be discussing these differences today.



    Take a look at the example above. The difference is quite evident, however I will try to explain it further.

word-break: break-all Irrespective of whether it’s a continuous word or many words, break-all breaks them up at the edge of the width limit even within the characters of the same word
word-wrap: break-word This will wrap long words onto the next line.break-word adjusts different words so that they do not break in the middle.
    So if you have many fixed-size spans which get content dynamically, you might just prefer using word-wrap: break-word, as that way only the continuous words are broken in between, and in case it’s a sentence comprising many words, the spaces are adjusted to get intact words (no break within a word).     In case you want to exp…

Onclick polygon

Yesterday we had a look at a simple polygon example. But that example was not exciting as it was all hard-coded with no user interaction and which means no fun! Today's example will deal with creating a polygon on the fly, i.e. an on-click polygon in action!

    The code for creating a polygon is very much similar to creating a polyline! The only difference is that you need to replace "Polyline" by "Polygon" in such examples. Let's head on to our code.


    The output of the above code can be viewed in the result section above. If you have any doubts or queries regarding the above code then please comment here or feel free to drop me a mail! Till then, happy mapping!

Get directions between different states in India

Having seen a simple hard coded directions example yesterday, today we will have a look at another simple example but not an hard coded one. In today's  example we will see the directions between different states in India. We have two simple list boxes stating Origin and Destination as lists of the states in India. You can select a state from either of the lists and then you will get the directions between the two selected cities.

    If you see yesterday's code and today's code you will find a lot of similarities and so  it would be easy to follow. The code will look lengthy, but it is just because of the list boxes code. So don't worry about the code, just go for it.


    The output of the above code will look as seen in the results section above. Hope you find this code helpful in understanding the directions services even further. Tomorrow, we will look at another - a bit complex example. Till then, happy mapping.
Note: The above code will not display any results …

Two maps on the same page - Side-by-side

How good I am feeling to post a code example after such a long time! It's been all "news" over the past so many posts! Well now that I am finally doing a code example, I am posting a very highly requested code sample. Placing two Google Maps on the same page (Now that's simple you would say!), but side by side. Now this is the thing that most people struggle with. Well, implementing the second part is also very simple, as you will see in today's code.

    Let's see the code. Here it is!



    The output of the above code will be as seen in the result section above.

    As most of you will realize, there are two maps, one centered at "Pune" and other at "Noida". Why I chose these two locations? Well, just like that!...The main issue of concern is how the maps appeared side-by-side and not one below the other as would be normal behavior of two "div" elements used in the same page. Now here is the trick! Check out the the first
