什么是“Dojo名称文本框”onremove事件？

Question

我的表单上有一个Dojo名称文本框“xe：djextNameTextBox”。单击[x]，将从列表中删除名称。如何在不解析getComponent（“myNameBox”）中的所有值的情况下检查删除或单击的确切名称.getValue（）？

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名称的信息。我不得不在之前的项目中处理同样的问题。

的XPage

设置viewScope var“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>

Managed Bean“viewController”

/**
 * Converts all filters to a useable format for dojo List Textbox
 * @return string of filters
 */
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 ViewFilter个对象，ViewFilter是一个简单的java类，包含有关过滤器的信息（在您的情况下是名称）
