打印DIV内容的最佳方法是什么?


当前回答

只需使用PrintJS

let printjs = document.createElement("script");
printjs.src = "https://printjs-4de6.kxcdn.com/print.min.js";
document.body.appendChild(printjs);

printjs.onload = function (){
    printJS('id_of_div_you_want_to_print', 'html');
}

打开一个新窗口 打开新窗口的文档对象,并在其中写入一个简单的文档,其中只包含您已经获得的div和必要的html头文件等-您可能还希望将文档拉入样式表,这取决于您的内容是什么 在新页面中放入一个脚本来调用window.print() 触发脚本

这应该可以工作:

function printDiv(divName) {
     var printContents = document.getElementById(divName).innerHTML;
     var originalContents = document.body.innerHTML;
     document.body.innerHTML = printContents;
     window.print();
     document.body.innerHTML = originalContents;
}
function printDomElement(element) {
    element.classList.add("printCss");

    let printId = "printId";
    let name = ".printCss";
    let rules = "-webkit-print-color-adjust:exact;height:100%;width:100%;position:fixed;top:0;left:0;margin:0;";

    var style = document.createElement('style');
    style.id = printId;
    style.media = "print";
    document.getElementsByTagName('head')[0].appendChild(style);

    if (!(style.sheet || {}).insertRule)(style.styleSheet || style.sheet).addRule(name, rules);
    else style.sheet.insertRule(name + "{" + rules + "}", 0);

    window.print();

    setTimeout(() => {
      element.classList.remove("printCss");
      let elem = document.getElementById(printId);
      if (elem) elem.remove();
    }, 500);

  }

与早期版本相比略有变化-在CHROME上测试

function PrintElem(elem)
{
    var mywindow = window.open('', 'PRINT', 'height=400,width=600');

    mywindow.document.write('<html><head><title>' + document.title  + '</title>');
    mywindow.document.write('</head><body >');
    mywindow.document.write('<h1>' + document.title  + '</h1>');
    mywindow.document.write(document.getElementById(elem).innerHTML);
    mywindow.document.write('</body></html>');

    mywindow.document.close(); // necessary for IE >= 10
    mywindow.focus(); // necessary for IE >= 10*/

    mywindow.print();
    mywindow.close();

    return true;
}

有点晚了,但我发现这真的很好!!

function printDiv(divID) {
    //Get the HTML of div
    var divElements = document.getElementById(divID).innerHTML;
    //Get the HTML of whole page
    var oldPage = document.body.innerHTML;

    //Reset the page's HTML with div's HTML only
    document.body.innerHTML = 
       "<html><head><title></title></head><body>" + 
              divElements + "</body>";

    //Print Page
    window.print();

    //Restore orignal HTML
    document.body.innerHTML = oldPage;
          
}
