什么是 "Dojo Name Text Box" onremove 事件？

Question

我的表单上有一个 Dojo 名称文本框 "xe:djextNameTextBox"。通过单击 [x]，它会从列表中删除一个名称。如何在不解析 getComponent("myNameBox").getValue()?

中的所有值的情况下检查删除或单击的确切名称

Answer 1

在我看来，处理此问题的唯一方法是解析所有值以获取确切删除了哪个名称的信息。我不得不在之前的项目中处理同样的问题。

设置视图范围变量"viewFiltersAsString":

    <xp:this.beforeRenderResponse><![CDATA[#{javascript:log('beforerenderresponse (start rendering)');
requestScope.start = new Date().getTime();
viewScope.put('viewFiltersAsString', viewController.getViewFiltersAsString());
viewController.actionSetPage();}]]></xp:this.beforeRenderResponse>

扩展库Dojo名称列表文本框控件：

<xe:djextListTextBox id="djFilters" multipleSeparator=","
    value="#{viewScope.viewFiltersAsString}" displayLabel="true"
    title="Hier klicken um Filter zu löschen">
    <xe:this.dataProvider>
        <xe:simpleValuePicker caseInsensitive="false"
            labelSeparator="~" valueListSeparator=","
            valueList="#{viewController.viewFiltersLabelsAsString}">
        </xe:simpleValuePicker>
    </xe:this.dataProvider>
    <xp:eventHandler event="onChange" submit="true" refreshMode="partial"
        refreshId="${javascript:compositeData.refreshId}" execMode="partial"
        action="#{javascript:viewController.setViewFiltersAsString(@Trim(viewScope.get('viewFiltersAsString')).toString())}">
    </xp:eventHandler>
</xe:djextListTextBox>

public String getViewFiltersAsString() {
    String filtersAsString = "";
    for (ViewFilter filter : viewFilters) {
        if (filtersAsString == "") filtersAsString = filter.getKey();
        else filtersAsString += "," + filter.getKey();
    }
    return filtersAsString;
}

public void setViewFiltersAsString(String viewFiltersAsString) {
    if (viewFiltersAsString != null && !viewFiltersAsString.equals("")) {
        List<String> currentfilters = Converter.toList(",", viewFiltersAsString);

        for (ViewFilter filter : viewFilters) {
            boolean remove = true;
            for (String currentFilter : currentfilters) {
                if (filter.getKey().equals(currentFilter)) {
                    remove = false;
                    break;
                }
            }
            if (remove) {
                // user can click only one filter at one time
                setActionViewFilter(viewFilters.removeFilter(filter));
                break;
            }
        }

    } else {
        setActionViewFilter(viewFilters.removeFilter(viewFilters.get(0)));
    }
}

提示：viewFilters 是 java.util.List 个 ViewFilter 对象，而 ViewFilter 是一个简单的 java class 保存有关过滤器的信息（在您的case a name)
