Question

我有一个text-editor

，我想要一个脚本，这样我们的徽标或水印将自动出现在文本编辑器的打印页面中，而无需在由contenteditable制作的文本编辑器中插入我们的徽标或水印，因为用户可以删除它，而我尝试某些技巧，但是所有这些技巧都是快速解决方案，在我的文本编辑器中不起作用，并且被某些用户忽略了，是否有任何解决方案或想法或提示可以对我有所帮助？这是文本编辑器的script

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");

Answer 1

如我在上面的评论中所述，您可以在printDoc()函数内部修改/添加到 printContents 变量。

我创建了一个变量WaterMark，您可以将其替换为徽标/水印。

这是一个JsFiddle Demo和下面的有效代码段。

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;
}
/*page margin*/
var cssPagedMedia = (function() {
  var style = document.createElement('style');
  document.head.appendChild(style);
  return function(rule) {
    style.innerHTML = rule;
  };
}());

cssPagedMedia.margin = function(margin) {
  cssPagedMedia('@page {margin: ' + margin + '}');
};

cssPagedMedia.margin('0');
/*page size*/
cssPagedMedia.size = function(size) {
  cssPagedMedia('@page {size: ' + size + '}');
};

var cssPagedMedia = (function() {
  var style = document.createElement('style');
  document.head.appendChild(style);
  return function(rule) {
    style.innerHTML = rule;
  };
}());
cssPagedMedia.size = function(size) {
  cssPagedMedia('@page {size: ' + size + '}');
};
cssPagedMedia.size('portrait');
