布局模板
示例
在 Foxit PDF SDK For Web 中,模板由包含 UIExtension 特定元素、属性和指令的 HTML 编写。UIExtension 将布局模板与来自组件、控制器和指令的信息相结合,以在浏览器中渲染 UI。以下代码段展示了带有 UIExtension 组件和指令的模板。
html
<webpdf>
<div class="toolbar" style="display:flex;flex-direction:row;padding:6px">
<print:print-ribbon-button></print:print-ribbon-button>
<ribbon-button name="freetext-typewriter"
@tooltip tooltip-title="toolbar.tooltip.typewriter.title"
@controller="states:CreateTypewriterController"
icon-class="fv__icon-toolbar-typewriter">toolbar.create.typewriter
</ribbon-button>
</div>
<div class="fv__ui-body">
<viewer @touch-to-scroll>
</viewer>
</div>
<template name="template-container">
<print:print-dialog></print:print-dialog>
</template>
</webpdf>
点击 run
按钮来查看运行结果:

布局模板格式说明
html
<!-- 布局模板必须以 <webpdf> 为根组件 -->
<webpdf>
<!-- 布局模板支持所有 html 标签和属性 -->
<div class="toolbar" style="display:flex;flex-direction:row;padding:6px">
<!-- 冒号前缀是组件模块的名字,组件名字和模快名必须是小写 -->
<print:print-ribbon-button></print:print-ribbon-button>
<!-- @开头的参数用于标记指令,@后面跟随的是指令的名称,如果指令注册在非根模快中,则指令名需要以 @module-name:directive-name 的格式编写 -->
<ribbon-button name="freetext-typewriter" @tooltip tooltip-title="toolbar.tooltip.typewriter.title"
@controller="states:CreateTypewriterController" icon-class="fv__icon-toolbar-typewriter">
toolbar.create.typewriter
</ribbon-button>
</div>
<div class="fv__ui-body">
<!-- Viewer 是用来显示 PDF 的区域,布局模板中必须有一个 viewer 组件 -->
<viewer @touch-to-scroll></viewer>
</div>
<!-- template 是被重写以后的 html template 标签, 通常用来容纳不需要立即显示的组件,比如对话框、右键菜单以及浮动框等 -->
<template name="template-container">
<print:print-dialog></print:print-dialog>
</template>
</webpdf>
如何指定布局模板和实现设备自适应
请参阅 Appearance 小节。
动态插入布局模板
请点击 run
按钮运行如下的示例:
html
<script>
var libPath = window.top.location.origin + '/lib';
var pdfui = new UIExtension.PDFUI({
viewerOptions: {
libPath: libPath,
jr: {
licenseSN: licenseSN,
licenseKey: licenseKey
}
},
renderTo: document.body,
addons: [
libPath + '/uix-addons/print'
]
});
pdfui.getComponentByName('home-tab-group-change-color')
.then(component => {
// after this component, insert a new group component.
component.after(`
<group>
<xbutton name="alert-btn" class="fv__ui-toolbar-show-text-button">Alert</xbutton>
</group>
`, [{
target: 'alert-btn',
config: {
callback: function () {
alert('Hello world')
}
}
}])
})
</script>
json
{
"iframeOptions": {
"style": "height: 500px"
}
}
支持插入模板的接口有:
- Component
- #after(component|template, fragments)
- #before(component|template, fragments)
- ContainerComponent
- #append(component|template,fragments)
- #prepend(component|template,fragments)
- #insert(component|template, index, fragments)
有关这些接口的详细信息,请参考 API Reference: Component 和 ContainerComponent
初始化时插入布局模板
