Dynamically Adding Content to a Widget

WilliamMiller4 — Sun, 12 Dec 2021 10:53:48 GMT

Hello,

I'm trying to use a format like the one used in Robert Scheitlin's Enhanced Search Widget where the main widget (widget.js) calls a function from a secondary file (List.js) to add content to the widget. Below are abbreviated versions of what my widget.js, List.js and widget.html look like.

Widget.js

define([
  //...
  './List',
  //...
  ],function(
  //...
  List, 
  //...
  ) {
  return declare([BaseWidget, _WidgetsInTemplateMixin], {
    //...
    list: null,
    //...
    
    startup: function() {
      this.inherited(arguments);
      //console.log('RatioQuery::startup');
      this.list.parentWidget = this;
    },
    
    //...
    
    _onSuccessfulQueryCompletion: function(results) {
      console.log('RatioQuery::_onSuccessfulQueryCompletion');
      //...
      this.list.add = ({
        accountNbr: accountNbr,
        addressLine1: addressLine1,
        grantor: grantor,
        grantee: grantee,
        saleDate: saleDate,
        salePrice: salePrice
      });
      //...
    },
    //...
    });
  }); ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

List.js

define([
  'dojo/_base/declare',
  'dijit/_WidgetBase',
  'dojo/_base/lang',
  'dojox/gfx',
  'dojo/on',
  'dojo/dom-construct',
  'dojo/dom-attr',
  'dojo/_base/array',
  'dojo/dom',
  'dojo/query',
  'dojo/dom-class',
  'dojo/dom-style',
  'dojo/Evented',
  'esri/symbols/jsonUtils'
  ],
  function(
    declare,
    _WidgetBase,
    lang,
    gfx,
    on,
    domConstruct,
    domAttr,
    array,
    dom,
    query,
    domClass,
    domStyle,
    Evented,
    jsonUtils
    ) {
    return declare([_WidgetBase, Evented], {

      'class': 'widgets-ratio-query-list',
      parentWidget: null,

      startup: function() {
        console.log("RatioQuery::List::startup");
        this.items = [];
        this._listContainer = domConstruct.create("div");
        domConstruct.place(this._listContainer, this.domNode);
      },

      add: function(item) {
        console.log("RatioQuery::List::add");
        
        if (arguments.length === 0) {
          return;
        }
        
        this.items.push(item);
        //console.info(this.items);
        
        var div = domConstruct.create("div");
        
        var parcelRecord = domConstruct.create("p");
        
        parcelRecord.textContent = parcelRecord.innerText = "Account No: " + item.accountNbr + "Address: " + item.addressLine1 + "Grantor: " + item.grantor + "Grantee: " + item.grantee + "Sale Date: " + item.saleDate + "Sale Price: " + item.salePrice;
        
        domConstruct.place(parcelRecord, div);
        
        domConstruct.place(div, this._listContainer);
        this.clearSelection();
      }
    });
  });‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Widget.html

  <div data-dojo-type="widgets/ratioQuery/List" data-dojo-attach-point="list" style="width:100%;clear:both;">
  </div>‍‍

I don't know why it's not working. Any help is greatly appreciated. Thank you.

William

William,

What errors (if any) are displayed in your browsers web console? What exactly is not working?

Hi Robert,

There are no errors, but the div where the content is supposed to go just has another empty div inside, as shown below.

<div data-dojo-type="widgets/RatioQuery/List" data-dojo-attach-point="list" style="width: 100%; clear: both;" id="uniqName_0_0" class="widgets-ratio-query-results" widgetid="uniqName_0_0">
      <div></div>
</div>‍‍‍

William,

If you uncomment line 9 below do you get that console line printed?

      add: function(item) {
        console.log("RatioQuery::List::add");
        
        if (arguments.length === 0) {
          return;
        }
        
        this.items.push(item);
        //console.info(this.items);
....‍‍‍‍‍‍‍‍‍‍

Hi Robert,

I shouldn't have had this.list.add = ({...});

I changed it to this.list.add({...}); and it works.

How do I get the vertical scroll bar? The content goes off the page and there is no way to view it.

William,

That is something you control in the css using an overflow css rule.
