Help altering a public Javascript

RyanLaird — Thu, 17 Jul 2014 20:55:40 GMT

Hello everyone,

I'm currently having issues getting my script to work with data hosted on my companies server. The code is copy/pasted from the following link, and the goal is to perform the exact same function but with our data. So far I keep getting an "unexpected token" error for one of the colons on line 71.

Below is my script, it's completely unmodified other than the names of the data, but I could have mistyped anywhere, if you catch something, please let me know. I've attached an HTML file of the script I've adapted.

Thanks!

On line 70 you have a "." rather than a comma.

Thank you so much! It's working fine now. It's always the stupidest thing isn't it?

I'm actually still having problems with this script, after the period was fixed the map displayed by my data still won't appear. I know it's there as it can be highlighted, and the pop-up works, but the data won't display until it is selected. I'm pretty sure I can find the problem but we're trying to get this finished ASAP.

Any help would be greatly appreciated!

Ryan,

you have your layer set to only show up if it is being selected:

mode: FeatureLayer.MODE_SELECTION

once you remove that, your layer will show.

Great! That's working like a charm! Thank you very much.

I hate to be a leech, but I have one more thing I would like to get done, but isn't 100% nessesary. My map doesn't zoom to the extent of my data like the other one, is there somewhere in the code I have to just punch in the extent? Sorry about this, I'm still quite new to Javascript.

	map = new Map("map", {
	infoWindow: popup,
	center:[-80.719892, 28.303518],
	zoom:13,
	slider: false
	});

Just replace the center with your coordinates and adjust zoom.

Just thought I would throw this out there. Here is a training video that may help with some debugging of your application. I didn't know much about developer tools until I saw this. It helped me a lot. Esri Training | Time-Saving Tips for JavaScript Developers‌

In addition, I believe that support is working on a series of blogs that help developers troubleshoot their scripts:

Sorry guys, haven't had time to check out those tutorials/ webinars and we're hoping to get htis script done today. Just have one last problem, I got every thing else working. When you type the OBJECTID into the url (?OBJECTID=) it will bring you to the map but will not link to the selected polygon. I think the problem is in lines 147-168 (where the parcel is selected from the url).

Pretty sure the error is with the original code too, rather than my changes. Just like how I had to delete "mode: FeatureLayer.MODE_SELECTION" after my changes. Anyway, thanks for all the help fellas.

I don't think I understand what you want to accomplish. Do you want to zoom to a feature when the user clicks on it?

Re: Help altering a public Javascript

RyanLaird — Tue, 22 Jul 2014 17:16:39 GMT

Nope, It's already doing that from the popup. The goal is that when an OBJECTID number is added to the url (in the format specified in line 101) the maps selects and zooms tot he corresponding feature, like in the example.That way, we could send a client a link to the map, and it would automatically select and zoom to whatever feature they are interested in.

We're looking to do more with this script down the road, but I'll have time to check out more tutorials before than. My schooling in Javascript was unfortunately quite minimal.

Ryan,

I wish I could help you, but I don't see the error. It might be good to start a new thread, since it got a little busy here
