如何将参数传递给DOJO中的自定义小部件？

Question

我在DOJO中创建了一些自定义小部件。 我需要能够在对象初始化时覆盖窗口小部件上的一些属性，例如：new _labelWebpart('my value here');

知道该怎么做吗？

 var widget2 = new _labelWebpart('my value here');


   define([
        "dojo/_base/declare",
        "dijit/_WidgetBase",
        "dijit/_TemplatedMixin",
        "dojo/text!./templates/label.html",
        "dojo/dom-style",
        "dojo/_base/fx",
        "dojo/_base/lang",
        "dojo/on",
        "dojo/mouse",
        "require"
    ], function (declare, _WidgetBase, _TemplatedMixin, template, domStyle, baseFx, lang, on, mouse, require) {
        return declare([_WidgetBase, _TemplatedMixin], {
            label: "Default text for label", // THIS VALUE SHOULD BE OVERWRITTEN WHEN PASSING ARGUMENT IN THE COSTRUCTOR
            templateString: template,
            baseClass: "Label",
              postCreate: function () {
                var domNode = this.domNode;
                  this.own(
                );
            }
        });
    });

Answer 1

我建议查看构造函数属性：

   return declare([_WidgetBase, _TemplatedMixin], {
        label: "Default text for label",
        templateString: template,

        // other stuff of your declare here

        constructor: function(override_arguments_here) {
           // your init code here to override the label from your arguments
        }
    });

Answer 2

构造函数是文件中的第一个执行点。声明骨架应如下：

    return declare("fileNameIfHTMLIsDifferent", [.....], {
		templateString: _templateString
		....
		, constructor: function(args) {
			declare.safeMixin(this, args);
			....
		}
		, postCreate: function() {
			this.inherited(arguments);
		    ....
		},
    startup: function() {
      this.inherited(arguments);
    }
	});
