WAB: Change Layer List 'Description' option

MatissValdmanis1 — Tue, 27 Oct 2015 21:43:57 GMT

Hello everyone,

I am using Web AppBuilder Developers Edition and want to change the Layer List "Description" option. When you run an app, when you click on the drop down beside a layer in the Layer List you are given the option to view the layer's 'Description'. This automatically opens the layer's REST endpoint URL.

I am wondering if there is a way to change the 'Description' option to show a custom URL website I can create myself, or even just the layer's "Description" value - you can edit this in an mxd by opening the layer's properties, under the General Tab, and then republishing the mxd to a Map Service that AGOL (and thus WAB) uses.

Matiss,

Sure you can have that option in the menu do what ever you want just open the:

[install dir]\server\apps\[app #]\widgets\LayerList\PopupMenuInfo.js

and find the _getATagLabel function this is the function that set the anchor hyper link to the layers rest end point page.

Thank you Robert! Definitely got me closer. However, I am not sure how to change which URL it goes do (please bear with me, I am still new to WAB JS).

As it stands I can't seem to get the layer's name string value - I could make a small html Description/metadata website for each layer if I could just get the layer's name value and pop the websites in the ...apps/[app #]/ folder.

Here is the code I have put in the _getATagLabel function:

_getATagLabel: function() {

var url;

var label;

var itemLayerId = this._layerInfo._isItemLayer && this._layerInfo._isItemLayer();

/*if (itemLayerId) {

url = portalUrlUtils.getItemDetailsPageUrl(

portalUrlUtils.getStandardPortalUrl(this.layerListWidget.appConfig.portalUrl),

itemLayerId);

label = this.nls.itemShowItemDetails;

} else if (this._layerInfo.layerObject &&

this._layerInfo.layerObject.url &&

(this._layerType === "CSVLayer" || this._layerType === "KMLLayer")) {

url = this._layerInfo.layerObject.url;

label = this.nls.itemDownload;

} else if (this._layerInfo.layerObject && this._layerInfo.layerObject.url) {

url = this._layerInfo.layerObject.url;

label = this.nls.itemDesc;

} else {

url = '';

label = this.nls.itemDesc;

} */ MV removed

url = ((this._layerInfo.layerObject.layerId) + '.com'); //MV added - returns 'undefined.com'

label = this.nls.itemDesc; //MV added

return '<a class="menu-item-description" target="_blank" href="' +

url + '">' + label + '</a>';

Matiss,

If you are just wanting the layers name then just use "name" there is no property called "layerId" in the layerObject.

url = ((this._layerInfo.layerObject.name) + '.com'); //MV added - returns 'layername.com'

Hi Robert,

Unfortunately

url = ((this._layerInfo.layerObject.name) + '.com');

returned undefined again,

However I've got a solution that works now:

} else if (this._layerInfo.layerObject && this._layerInfo.layerObject.url) {

//url = this._layerInfo.layerObject.url;

url = ((this._layerInfo.id) + '.html'); //MV added

label = this.nls.itemDesc;

}

That code returns .../webappbuilder/apps/3/(Mapservice_Name)_3308_3.html

I can build the description/metadata websites off of this.

Thank you so much for the help!

Also

} else if (this._layerInfo.layerObject && this._layerInfo.layerObject.url) {

//url = this._layerInfo.layerObject.url;

url = ((this._layerInfo.title) + '.html'); //MV added

label = this.nls.itemDesc;

}

Works, returns
.../webappbuilder/apps/3/(layer name).html

However spaces in the layer name make it unusable
