Is there a function to read a text file into a variable? I see in the docs a dhc.files.writeTextFile(), dhc.files.deleteFile(), and dhc.files.fileExists(), but no similar dhc.files.readTextFile().

Hello Bryce,

Please, take a look at the "Files" sample app. There is no "readTextFile" because we can use a XMLHttpRequest ("jQuery.get()" for example) without problems in the new generation of DecSoft HTML Compiler. In the referred sample you can see how we read a text file (previously write) with the below Javascript code:


  $('#read-file-in-root-button').on('click', function () {
  
    dhc.files.fileExists({
      filePath: 'my_text_file.txt'
    }).then((result) => {
      if (result) {
        // In DecSoft HTML Compiler apps we can use AJAX requests to read local app files:
        $.get('my_text_file.txt', function (contents) {
          $('#input-textarea').val(contents);
        });		   
  	  } else {
  	    alert('The my_text_file.txt file do not exist.');
  	  }
    },
    (error) => {
      alert('An error occur: ' + error);
    });	 	 
  });
