Adding variable data from an external file into Google Maps V3

Question

Adding variable data from an external file into Google Maps V3

Is it possible to use includes in Java for Google Maps like you can in PHP? Currently, I have code that assigns colors to polygons.

var lineColor = {
"Tornado Warning":                   "#FF0000",
"Severe Thunderstorm Warning":       "#FFFF33",
"Flash Flood Warning":               "#00FF00",
};

As the list grows longer, I want to avoid cluttering the main code. Can I store this color assignment in a separate file and call it instead? Here's what I have tried:

// Assign colors to alerts
    var lineColor = 'xml/alertColors.html';

I created an HTML file with the colors listed as follows:

<html>
<script type="text/javascript">


{
"Tornado Warning":                   "#FF0000",
"Severe Thunderstorm Warning":       "#FFFF33",
"Flash Flood Warning":               "#00FF00",
"Flood Advisory":                    "#00FF7F",
"Special Weather Statement":         "#00FFFF",
};

</script>
</html>

It doesn't seem to be working. Am I doing something wrong or is including files in JavaScript not the same as in PHP?

-Thanks

To implement custom line colors in your project, start by creating a new file called line_color.js. You can choose any name for this file as long as it ends with .js. Then, input the following code:

var lineColor = {
    "Tornado Warning": "#FF0000",
    "Severe Thunderstorm Warning": "#FFFF33",
    "Flash Flood Warning": "#00FF00" // avoid using a comma after the last entry
};

In the <head> section of your main HTML file, include a reference to this JavaScript file like so:

<script type="text/javascript" src="line_color.js"></script>

You can now utilize these custom settings and variables within your project. For example:

<script>
    alert(lineColor['Tornado Warning']); // This will display #FF0000
</script>

Finally cracked the code. I simply moved the entire var lineColors with its array into a separate .js file, just like how I initially set it up, and then referenced it above the script as before.

<script type="text/javascript" src="line_color.js"></script>

I didn't need to make any additional calls to the original file since it was already included. This allowed the script to pull the array seamlessly from the external file, resulting in cleaner and more organized code without the lengthy data array.
