How to Generate and Download Text File By Oracle Apex 5.1 Using JavaScript

It is very easy to generate a text file from oracle apex by using JavaScript . Here I describe it step by step.

1.  First create a page and create a region with (Type: Static Content).

2. Create a textarea type item. (Name: P21_CONTENT ) 

3. Then copy-pest the JavaScript code into  Page >>JavaScript >>Function and Global Variable        Declaration. 

(function () {

var textFile = null,

  makeTextFile = function (text) {

    var data = new Blob([text], {type: 'text/plain'});

    if (textFile !== null) {

      window.URL.revokeObjectURL(textFile);

    }

    textFile = window.URL.createObjectURL(data);

    return textFile;

  };

  var create = document.getElementById('create'),

    textbox = document.getElementById('P21_CONTENT');

    var link = document.getElementById('downloadlink');

    link.href = makeTextFile(textbox.value);

   link.style.display = 'block';

})();

4.  P21_CONTENT it is the CSS  ID of  P21_CONTENT of  textarea item.

5. Create a button with Behavior>>Action>>Submit Page. And another one button for clearing the data of the textarea.  

6. Then  copy-pest the HTML code into the Region >> Source 

   <a download="info.txt" id="downloadlink" width="107" 

   height="10" ><b>Download</b></a> 

JOB DONE...

Now you can see a page like this. Here you write any thing on the textarea and click on Generate Text button.  Finally Click on Download link.
