Question

sap.m.Page和sap.m.semantic.SemanticPage之间有什么区别？因为两者都适用于FIORI页面。

Answer 1

页面是具有一些属性的简单容器，例如“ title”和“ showNavButton”。 Page中的其他所有内容都是您可以从库中自由选择并设置它们的控件。例如，如果要添加页脚，则可以使用库中的通用<footer>控件。

SemanticPage也是一个容器，但是，它具有许多可以使用的特定控件，并且它们具有预定义的行为。例如，它具有特定的页脚（<semantic:footer>...</semantic:footer>），旨在每次使用时都具有相同的外观。

以下代码显示了SAP UI5 SDK中的语义页面示例，您可以看到语义页面中使用了许多<semantic:控件：

<semantic:SemanticPage
        id="mySemanticPage"
        headerPinnable="true"
        toggleHeaderOnTitleClick="true"
        preserveHeaderStateOnScroll="false"
        titleAreaShrinkRatio="1:1.6:1.6"
        showFooter="true">

        <!-- Title Heading-->
        <semantic:titleHeading>
            <Title text="{/title}" />
        </semantic:titleHeading>

        <!-- Title Breadcrumbs-->
        <semantic:titleBreadcrumbs>
            <Breadcrumbs>
                <Link text="Home" />
                <Link text="Page 1" />
                <Link text="Page 2" />
                <Link text="Page 3" />
                <Link text="Page 4" />
                <Link text="Page 5" />
            </Breadcrumbs>
        </semantic:titleBreadcrumbs>

        <!-- Title Snapped On Mobile Content-->
        <semantic:titleSnappedOnMobile>
            <Title text="Header Title On Phone"/>

Answer 2

语义页面是一个增强的sap.m.Page，它可以包含具有语义含义的控件（另请参见sap.m.semantic.SemanticControl）。 sap.m.semantic.SemanticPage #semanticControls聚合中指定的内容将自动定位在专用部分中页脚的页脚或页眉，取决于控件的语义。例如，sap.m.semantic.PositiveAction类型的语义按钮将位于页脚的右侧，并且相对于任何其他包含的语义控件，在逻辑上正确的顺序顺序。
