我有以下小部件HTML。Dijit/form /选择内部Dijit/TitlePane自定义小部件的一部分在错误位置打开下拉列表
<div class="expandableSearch">
<div data-dojo-type="dijit/TitlePane" data-dojo-props="title:'${prefixTitle}', open:false" id="${containedWidgetId}titleNodePane">
<div id="container"
class="${baseClass}Container"
data-dojo-attach-point="containerNode"></div>
</div>
</div>
与它背后的以下JavaScript：
/**
* Javascript for ExpandableSearchComponent
*/
define([ "dojo/_base/declare", "dijit/_WidgetBase", "dijit/_TemplatedMixin",
"dojo/text!./templates/ExpandableSearchComponent.html",
"dijit/TitlePane", "dijit/_WidgetsInTemplateMixin", "dijit/registry",
"dojo/on", "dojo/aspect", "dojo/_base/lang", "dojo/dom",
"dojo/dom-attr", "js/utils/CommonUtils", "dijit/focus" ], function(declare,
_WidgetBase, _TemplatedMixin, template, TitlePane,
_WidgetsInTemplateMixin, registry, on, aspect, lang, dom, domAttr,
CommonUtils, focusUtil) {
return declare([ _WidgetBase, _TemplatedMixin, _WidgetsInTemplateMixin ], {
templateString : template,
prefixTitle : "",
containedWidgetId : "",
defaultValue : "",
startup : function() {
this.inherited(arguments);
var containedWidgetId = this.containedWidgetId;
var containedWidget = registry.byId(this.containedWidgetId);
if (typeof containedWidget === "undefined") {
containedWidget = dom.byId(this.containedWidgetId);
}
var titlePane = registry.byId(this.containedWidgetId
+ "titleNodePane");
this.own(on(titlePane, "Show", function() {
if (typeof containedWidget.loadAndOpenDropDown === "function") {
containedWidget._aroundNode = containedWidget.focusNode;
containedWidget.loadAndOpenDropDown();
}
focusUtil.focus(dom.byId(containedWidgetId));
}));
this.own(on(titlePane, "Hide", function() {
if (typeof containedWidget.closeDropDown === "function") {
containedWidget.closeDropDown();
}
}));
this.own(on(containedWidget, "change", function(event) {
var newVal = "";
if (typeof containedWidget.attr == "function"
&& containedWidget.attr("displayedValue") !== null) {
newVal = containedWidget.attr("displayedValue");
}
if (typeof event === "object") {
newVal = containedWidget.value;
}
var newTitle = this.prefixTitle + newVal;
if (newTitle.length > 35) {
newTitle = newTitle.substring(0, 32) + "...";
}
titlePane.set("title", newTitle);
if (titlePane.open) {
titlePane.toggle();
}
}.bind(this)));
},
reset : function() {
var containedWidget = registry.byId(this.containedWidgetId);
if (typeof containedWidget === "undefined") {
containedWidget = dom.byId(this.containedWidgetId);
}
if (typeof containedWidget.set === "function"
&& containedWidget.attr("displayedValue") !== null) {
containedWidget.set("value", this.defaultValue);
}
if (typeof containedWidget.set === "function"
&& containedWidget.attr("displayedValue") === null) {
containedWidget.set("value", this.defaultValue);
}
if (typeof containedWidget.onChange !== "function") {
domAttr.set(containedWidget, "value", this.defaultValue);
if ("createEvent" in document) {
var evt = document.createEvent("HTMLEvents");
evt.initEvent("change", false, true);
containedWidget.dispatchEvent(evt);
} else {
containedWidget.fireEvent("onchange");
}
}
}
});
});
从本质上讲，HTML和Javascript的结合只是一个dijit/TitlePane有一些额外的JavaScript来
- 自动设置的标题窗格;
- Automaticaly打开和关闭底层元素，如果它有一个下拉菜单;
- 自动将焦点设置为包含的元素。
像这样来使用：
<div data-dojo-type="js/widgets/ExpandableSearchComponent" id="machineSearchView.operatingSystemExpandableSearch"
data-dojo-props="prefixTitle: '<s:property value="%{getText('label.machine.operatingSystem')}"/>: ', containedWidgetId: 'machineSearchView.operatingSystem', defaultValue: '-1'">
<div data-dojo-type="dojo/store/Memory"
data-dojo-id="operatingSystemStore"
data-dojo-props="<s:property value='%{getOperatingSystemTypeCodeJsonString()}'/>"></div>
<s:set name="operatingSystem" value="machineSearchView.operatingSystem"
scope="request"></s:set>
<div data-dojo-type="dijit/form/Select" class="readOnlySelect"
data-dojo-props="store:operatingSystemStore, labelAttr: 'label', sortByLabel: false, value:'${operatingSystem}'"
name="machineSearchView.operatingSystem" id="machineSearchView.operatingSystem"></div>
</div>
当我打开它，它看起来像这样：
正如你所看到的，dijit/form/Select打开SelectMenu的TitlePane组件而不是选择div本身。你可以看看SelectMenu旁边的选择。
由于我喜欢它看一个例子：
的containedWidget._aroundNode = containedWidget.focusNode;是企图使其工作基础上https://davidwalsh.name/dijit-dropdowns，但它并没有帮助。我不知道还有什么我可以尝试。我已经试着去深入调试Dojo组件内部的狂欢，但无济于事？
我该如何解决这个问题？
