Text to HTML Converter Integration in SAP UI5

Preface – This post is part of the UI5 Integration Programs series.

Introduction

A Text to HTML Converter is a tool or software program that converts plain text into HTML (HyperText Markup Language) format. HTML is a markup language used to create web pages and display content on the internet. The HTML format provides a way to structure text and add visual elements, such as headings, paragraphs, lists, images, and links.

When you use a Text to HTML Converter, you can take plain text and turn it into an HTML document, which can then be displayed on the web. The converter adds the necessary HTML tags and syntax to format the text and create a web page. This can be useful for people who want to publish text content on the web but don’t have experience with HTML coding.

When do we need to convert Text to HTML in UI5?

In SAP UI5, you might need to convert text to HTML when you want to display dynamic content on a web page, and you need to format that content in a specific way. For example, you might want to display text with different fonts sizes, colors, or styles. You might also want to include links, images, or lists in your content.

When you use UI5 to build web applications, you can use the HTML format to create rich and dynamic user interfaces. The conversion from plain text to HTML can be done programmatically, for example, in a controller or helper class, and then the HTML content can be added to a UI5 control, such as a sap.m.Text control, for display in the user interface.

This allows you to dynamically create and display formatted content in your UI5 applications, and provides a flexible and powerful way to present data and information to your users.

The major business use case for Text to HTML converters is for the creation of an Email template. A business guy will create a template for you, and you will have to convert it into HTML, so that the same can be sent via Email. An email always sends data in HTML format.

Text to HTML Converter Integration in SAP UI5

1. Using RichTextEditor

You can use RichTextEditor in view (commented here) or in the controller. When you try to get its value using getValue() function, then it always return HTML format data.

View.xml

<mvc:View controllerName="Test.Test.controller.Main" xmlns:mvc="sap.ui.core.mvc" displayBlock="true" xmlns="sap.m" xmlns:core="sap.ui.core"
    xmlns:html="http://www.w3.org/1999/xhtml" xmlns:l="sap.ui.layout" xmlns:f="sap.ui.layout.form" xmlns:RichTextEditor="sap.ui.richtexteditor">
    <Shell id="shell">
        <App id="app">
            <pages>
                <Page id="page" title="Text to HTML Converter using UI5">
                    <content>
                        <VBox class="sapUiSmallMarginBegin">
                            <HBox>
                                <!--<RichTextEditor:RichTextEditor id="RichTextEditor1" height="300px" width="500px"/>-->
                                <Text id="text2" class="sapUiSmallMarginBeginEnd sapUiSmallMarginTop"/>
                                <VBox id="editorContainer"></VBox>
                                <VBox class="sapUiLargeMargin">
                                    <Button text="Convert" width="100px" press="onConvert"/>
                                    <Button id="uploadText" text="Copy" width="100px" enabled="false" press="onSave"/>
                                </VBox>
                                <TextArea id="RichTextEditor2" value='' editable="false" height="300px" width="500px"/>
                            </HBox>
                        </VBox>
                    </content>
                </Page>
            </pages>
        </App>
    </Shell>
</mvc:View>

Controller.js

sap.ui.define([
    "sap/ui/core/mvc/Controller"
], function (Controller) {
    "use strict";

    return Controller.extend("Test.Test.controller.Main", {
        onInit: function () {
            var that = this;
            sap.ui.require(["sap/ui/richtexteditor/RichTextEditor"],
                function (RTE) {
                    that.oRichTextEditor = new RTE("myRTE", {
                        editorType: sap.ui.richtexteditor.EditorType.TinyMCE,
                        width: "500px",
                        height: "300px",
                        showGroupFont: true,
                        tooltip: "Enter Text",
                        value: ""
                    });

                    that.getView().byId("editorContainer").addItem(that.oRichTextEditor);
                });
        },

        onConvert: function () {
            var text = this.getView().byId("RichTextEditor2");
            var value = this.getView().byId("editorContainer").getItems()[0].getValue();
            if (value.length > 0) {
                text.setValue(value);
                this.getView().byId("uploadText").setEnabled(true);
            } else {
                sap.m.MessageBox.information("Empty Input. Please type something");
            }
        }
    });
});

Text to HTML Converter using UI5

2. Using JavaScript

In SAP UI5, you can integrate a Text to HTML Converter in your web application by using JavaScript or any other programming language. Here’s an example of how you could implement a Text to HTML Converter in a UI5 application using JavaScript:

  1. Create a function that converts text to HTML format. This function can be called whenever you need to convert text to HTML.
    function convertTextToHTML(text) {
      // Use regular expressions or other string manipulation techniques to convert the text to HTML format
      var html = text.replace(/\n/g, "<br>");
      return html;
    }
    
  2. In your UI5 controller or helper class, call the convertTextToHTML function and pass the text that you want to convert.
    var html = convertTextToHTML("This is some sample text\nThis is a new line");
    
  3. Finally, set the HTML content to a UI5 control, such as a sap.m.Text control, and add it to the view.
    var textControl = new sap.m.Text({
      text: html
    });
    this.getView().addContent(textControl);
    

    This is just one way to implement a Text to HTML Converter in SAP UI5. The exact implementation will depend on the specific requirements of your application, such as the format of the input text and the desired output HTML format. However, this example should give you a general idea of how to integrate a Text to HTML Converter in your UI5 application.
