Wie exportiere ich HTML, um ein Word-Dokument zu erstellen?

Vorwort:

Während der Projektentwicklung stieß ich auf die Notwendigkeit, den Inhalt der HTML-Seite in ein Word-Dokument zu exportieren, also habe ich mir Folgendes ausgedacht Aufsatz.

Natürlich war die Projektentwicklungszeit etwas knapp und das erste, woran ich dachte, war die Verwendung von Plug-Ins, also schaute Baidu vorbei. Hier sind zwei Methoden zum Exportieren von Word-Dokumenten.

Methode 1: Wort über jquery.wordexport.js exportieren

Hinweis: Kompatibel mit IE9 und höher

Durchsuchen Sie den Code des Plug-Ins jquery.wordexport.js und Erfahren Sie mehr darüber. Dieses Plug-in kann Text und Bilder exportieren. Die Bilder werden zunächst in Form einer Leinwand gezeichnet. Der Text muss auf dem FileSaver.js-Plug-in basieren. Das js-Plug-in verwendet hauptsächlich die neue Dateioperationsfunktion von H5 new Blob() und new FileReader()

, um den Textexport zu implementieren.

Plug-in-Quellcode:

Rufen Sie direkt die Schnittstelle wordExport() auf, um das Word-Dokument zu exportieren, und Die übergebenen Parameter sind der Name der exportierten Word-Datei.

Ergänzung:

Es ist ungültig, den Stil durch unser normales Schreiben im externen Stil festzulegen. Durch persönliche Praxis habe ich festgestellt, dass es notwendig ist, den Inline-Stil und die Einheit zu schreiben muss der Konfiguration des Wortes

Einstellung der Einheit pt folgen.

Das Plug-in jquery.wordexport.js ist mit einem Stil konfiguriert, der es uns ermöglicht, die Stileinstellungen zu ergänzen:

Aber nach persönlicher Übung habe ich set it Der Stil kann nicht wirksam werden, er kann nur durch Inline-Einstellung wirksam werden.

Methode 2: Generieren Sie ein Word-Dokument über die Baidu-JS-Vorlagen-Engine

Legen Sie hauptsächlich das entsprechende über die JS-Vorlage fest Tag, und dann exportiert XDoc.to(baidu.template()) Word, und der Vorteil der Verwendung der Baidu js Template Engine besteht darin, dass sie auch PDF-Dateien exportieren kann.

Vollständige Demo:

Hier rufe ich die js-Vorlage auf, um sie über die renderTemplate-Funktion in HTML zu rendern und so die Kombination aus Textanzeige und exportiertem Inhalt zu realisieren. Und da das hier exportierte Word-Dokument einen speziellen Stil haben muss, können wir ihn festlegen, indem wir .class unter der Seitenstilanzeige hinzufügen.
