The PDF Viewer library allows you to switch or load PDF documents dynamically after the initial load operation. To achieve this, load the PDF document as a base64 string or file name into the PDF Viewer control using the Load() method dynamically.
The following steps are used to load the PDF document dynamically.
Step 1: Follow the steps provided in the link to create a simple PDF Viewer sample.
Step 2: Use the following code snippet to load the PDF document using a base64 string.
<template>
<div>
<button v-on:click="load_1">LoadDocumentFromBase64</button>
<div>
<ejs-pdfviewer
id="pdfViewer"
:serviceUrl="serviceUrl"
:documentPath="documentPath">
</ejs-pdfviewer>
</div>
</div>
</template>
<script>
import Vue from 'vue';
import { PdfViewerPlugin, Toolbar, Magnification, Navigation, LinkAnnotation, BookmarkView,
ThumbnailView, Print, TextSelection, TextSearch, Annotation, FormDesigner, FormFields} from '@syncfusion/ej2-vue-pdfviewer';
Vue.use(PdfViewerPlugin);
export default {
data () {
return {
serviceUrl:"https://ej2services.syncfusion.com/production/web-services/api/pdfviewer",
documentPath:"PDF_Succinctly.pdf",
};
},
provide: {
PdfViewer: [Toolbar, Magnification, Navigation, LinkAnnotation, BookmarkView,
ThumbnailView, Print, TextSelection, TextSearch,Annotation, FormDesigner, FormFields]},
methods: {
// Load the PDF document from a Base64 string
load_1: function (event) {
var viewer = document.getElementById('pdfViewer').ej2_instances[0];
viewer.load('data:application/pdf;base64,'+ AddBase64String, null);
}
}
}Step 3: Use the following code snippet to load the PDF document using the document name.
<template>
<div>
<button v-on:click="load_2">LoadDocument</button>
<div>
<ejs-pdfviewer
id="pdfViewer"
:serviceUrl="serviceUrl"
:documentPath="documentPath">
</ejs-pdfviewer>
</div>
</div>
</template>
<script>
import Vue from 'vue';
import { PdfViewerPlugin, Toolbar, Magnification, Navigation, LinkAnnotation, BookmarkView,
ThumbnailView, Print, TextSelection, TextSearch, Annotation, FormDesigner, FormFields} from '@syncfusion/ej2-vue-pdfviewer';
Vue.use(PdfViewerPlugin);
export default {
data () {
return {
serviceUrl:"https://ej2services.syncfusion.com/production/web-services/api/pdfviewer",
