Hello, I'm trying to integrate the new ClusterLayer sample introduced at 3.0 (http://help.arcgis.com/en/webapi/javascript/arcgis/demos/layers/layers_point_clustering.html) into my application but I'm having some problems with the dojo.require statement. So, I've included the dojo.require("extras.Clusterlayer"); statement in my Default.aspx page. But when I try to load my application with that statement included, it fails to load...I just end up with a blank page. Then I saw this code in the sample: var dojoConfig = { parseOnLoad: true, packages: [{ "name": "extras", "location": location.pathname.replace(/\/[^/]+$/, '') + "/extras" }] }; So I included it in mine and still nothing. I realized the "location" property's pathname was probably incorrect, but I've tried everything I can think of, including setting "location" to "help.arcgis.com/en/webapi/javascript/arcgis/demos/layers/extras" which I assume is what it must be in the sample but no dice. Can anyone instruct me on what I'm doing wrong here? Thanks!

nav[aria-label="Primary Navigation"] { padding: 0; & ul { list-style: none; width: 100%; display: flex; flex-direction: row; justify-content: start; align-items: start; gap: 30px; padding: 0; & li { margin: 0; } & ul li { list-style: none; } } }

Trying to Integrate 3.0 ClusterLayer

Hello,

I'm trying to integrate the new ClusterLayer sample introduced at 3.0 (http://help.arcgis.com/en/webapi/javascript/arcgis/demos/layers/layers_point_clustering.html) into my application but I'm having some problems with the dojo.require statement.

So, I've included the dojo.require("extras.Clusterlayer"); statement in my Default.aspx page. But when I try to load my application with that statement included, it fails to load...I just end up with a blank page. Then I saw this code in the sample:

<script>
var dojoConfig = {
parseOnLoad: true,
packages: [{
"name": "extras",
"location": location.pathname.replace(/\/[^/]+$/, '') + "/extras"
}]
};
</script>

So I included it in mine and still nothing. I realized the "location" property's pathname was probably incorrect, but I've tried everything I can think of, including setting "location" to "help.arcgis.com/en/webapi/javascript/arcgis/demos/layers/extras" which I assume is what it must be in the sample but no dice.

Can anyone instruct me on what I'm doing wrong here? Thanks!

This usually happens when you try to reference something in the library before it's been loaded. We mention this in the Migrating to 3.0 doc.

Ok, it works fine now.

Another question: How to automatically zoom in the selected cluster by one click, then show the points?

When I added the point clustering js to my project with other js files, the error "esri is not defined" occurred. How to fix this bugs? Thanks!

Try loading the .json file directly in your browser. If you still get a 404, and you're sure that the path to the file is correct, you probably need to configure IIS to server JSON: http://stackoverflow.com/q/332988/1934

Thank you very much.It's work in my IIS server.

Rather than running the sample by double-clicking it, you need to use a web server (like IIS or Apache). Your web server can be local. The important part is that you run JS API samples over http:// rather than file://.

I used the web server(IIS),it can work but also have some problem.It just show a map without the point.The firebug note me that Error: Unable to load data/1000-photos.json status:404

the layers_point_clustering.html file can't work in my browser after the file double clicked.my aim is the file can work in my browser.

We made an update and missed adding the extras directory and ClusterLayer.js file to the download. I fixed this yesterday. Please re-download: http://www.arcgis.com/sharing/content/items/1a6528fd3c774cfbbdf46df66c42958f/data

thank you for your help. but i also can't run the api that [URL="http://help.arcgis.com/en/webapi/javascript/arcgis/demos/layers/layers_point_clustering.html"] successfully by vs2008. at first,the firebug note me that extras/ClusterLayer.js not found. but after extras/ClusterLayer.js added to dojo library,the firbug note me that map.js not found. so i want know what happen.
thanks, I am a novice programming.

thanks

Now then, I think there is a small fault in the extras/ClusterLayer.js file included in Esri's sample. There is a line of code that says:
alert('Sorry, that cluster contains more than 1000 points.  Zoom in for more detail.');
I submit it should say:
alert('Sorry, that cluster contains more than ' + this._maxSingles + ' points. Zoom in for more detail.');
As maxSingles is an option provided to the user during configuration of a new ClusterLayer.

Thanks,
Mark

You're right, I'll make the change.

Finally got it working...aiming at the correct path to parse the extras library proved a pain, but it works!

This was discussed in a previous thread, but also make sure that your server environment is configured to serve .json, as that is how the point data for this sample is stored under the "/data" folder.

I just ran a quick test using the cluster sample code and was able to run it locally. Here are the steps I performed:
1. Downloaded the zip file containing the cluster code from here:
http://www.arcgis.com/home/item.html?id=4174dcae65bf42e1b776c17da4b279c1
2.Unzip the contents into a folder called cluster in my web server root direction (c:/inetpub/wwwroot)
3.Test the app in my browser
http://localhost/cluster/layers_point_clustering.html

Indeed, simply copying the sample code and trying to run it locally produces the same problem. Any assistance available?

ESRI, any help?
