/ 18 ноября 2018

У меня есть текстовый редактор

, и я хочу, чтобы когда пользователь печатал текст в нем, на напечатанной странице был водяной знак, а когда я пробовал его с текстовым водяным знаком, он работаетно с водяным знаком изображения это не работает, и вот сценарий печати 

function printDoc() {
 if (!validateMode()) { return; }
var printContents = document.getElementById('textBox').innerHTML;
var originalContents = document.body.innerHTML;
document.body.innerHTML = printContents+'<div style="width:150px;position:fixed;bottom:5px;right:5px;opacity:.5;">Display Logo Here...</div>';
window.print();
document.body.innerHTML = originalContents;
}

и даже когда я пытался поставить водяной знак перед printContents, он не работает вообще, и вот полный скрипт текстового редактора JsFiddle Demo 

var oDoc, sDefTxt;

function initDoc() {
  oDoc = document.getElementById("textBox");
  sDefTxt = oDoc.innerHTML;
  if (document.compForm.switchMode.checked) {
    setDocMode(true);
  }
}

function formatDoc(sCmd, sValue) {
  if (validateMode()) {
    document.execCommand(sCmd, false, sValue);
    oDoc.focus();
  }
}

function validateMode() {
  if (!document.compForm.switchMode.checked) {
    return true;
  }
  alert("Uncheck \"Show HTML\".");
  oDoc.focus();
  return false;
}

function setDocMode(bToSource) {
  var oContent;
  if (bToSource) {
    oContent = document.createTextNode(oDoc.innerHTML);
    oDoc.innerHTML = "";
    var oPre = document.createElement("pre");
    oDoc.contentEditable = false;
    oPre.id = "sourceText";
    oPre.contentEditable = true;
    oPre.appendChild(oContent);
    oDoc.appendChild(oPre);
    document.execCommand("defaultParagraphSeparator", false, "div");
  } else {
    if (document.all) {
      oDoc.innerHTML = oDoc.innerText;
    } else {
      oContent = document.createRange();
      oContent.selectNodeContents(oDoc.firstChild);
      oDoc.innerHTML = oContent.toString();
    }
    oDoc.contentEditable = true;
  }
  oDoc.focus();
}




function printDoc() {
  if (!validateMode()) {
    return;
  }
  // Add your watermark here  
  var WaterMark = '<div style="width:150px;position:fixed;bottom:5px;right:5px;opacity:.8;">StackOverFlow</div>';
  var printContents = document.getElementById('textBox').innerHTML;
  var originalContents = document.body.innerHTML;
  document.body.innerHTML = printContents + WaterMark;
  window.print();
  document.body.innerHTML = originalContents;
}

Что мне нужно сделать, чтобы добавить img в качестве водяного знака на печатную страницу?

Существует гораздо более простой способ сделать это с помощью таблиц стилей, предназначенных для печати. ​​
