打印DIV内容的最佳方法是什么?


当前回答

虽然@BC的答案最好打印一页。

但要打印多页A4大小的同时按ctrl+P以下解决方案可能会有所帮助。

@media print{
html *{
    height:0px!important;
    width:0px !important;
    margin: 0px !important;
    padding: 0px !important;
    min-height: 0px !important;
    line-height: 0px !important;
    overflow: visible !important;
    visibility: hidden ;


}


/*assing myPagesClass to every div you want to print on single separate A4 page*/

 body .myPagesClass {
    z-index: 100 !important;
    visibility: visible !important;
    position: relative !important;
    display: block !important;
    background-color: lightgray !important;
    height: 297mm !important;
    width: 211mm !important;
    position: relative !important;

    padding: 0px;
    top: 0 !important;
    left: 0 !important;
    margin: 0 !important;
    orphans: 0!important;
    widows: 0!important;
    overflow: visible !important;
    page-break-after: always;

}
@page{
    size: A4;
    margin: 0mm ;
    orphans: 0!important;
    widows: 0!important;
}}

我编写了一个插件来解决这种情况。我对现有的插件不满意,开始做一些更广泛/可配置的东西。

与最佳答案相同,以防你需要像我一样打印图像:

如果你想打印图像:

function printElem(elem)
    {
        Popup(jQuery(elem).attr('src'));
    }

    function Popup(data) 
    {
        var mywindow = window.open('', 'my div', 'height=400,width=600');
        mywindow.document.write('<html><head><title>my div</title>');
        mywindow.document.write('</head><body >');
        mywindow.document.write('<img src="'+data+'" />');
        mywindow.document.write('</body></html>');

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

        return true;
    }

如果你想拥有原始文档的所有样式(包括内联样式),你可以使用这种方法。

复制完整的文档 将body替换为要打印的元素。

实现:

class PrintUtil {
  static printDiv(elementId) {
    let printElement = document.getElementById(elementId);
    var printWindow = window.open('', 'PRINT');
    printWindow.document.write(document.documentElement.innerHTML);
    setTimeout(() => { // Needed for large documents
      printWindow.document.body.style.margin = '0 0';
      printWindow.document.body.innerHTML = printElement.outerHTML;
      printWindow.document.close(); // necessary for IE >= 10
      printWindow.focus(); // necessary for IE >= 10*/
      printWindow.print();
      printWindow.close();
    }, 1000)
  }   
}

我使用Bill Paetzke的答案打印一个div包含图像,但它不能与谷歌chrome

我只需要添加这一行myWindow.onload=function(){使它工作,这里是完整的代码

<html>
<head>
    <script type="text/javascript" src="http://jqueryjs.googlecode.com/files/jquery-1.3.1.min.js"> </script>
    <script type="text/javascript">
        function PrintElem(elem) {
            Popup($(elem).html());
        }

        function Popup(data) {
            var myWindow = window.open('', 'my div', 'height=400,width=600');
            myWindow.document.write('<html><head><title>my div</title>');
            /*optional stylesheet*/ //myWindow.document.write('<link rel="stylesheet" href="main.css" type="text/css" />');
            myWindow.document.write('</head><body >');
            myWindow.document.write(data);
            myWindow.document.write('</body></html>');
            myWindow.document.close(); // necessary for IE >= 10

            myWindow.onload=function(){ // necessary if the div contain images

                myWindow.focus(); // necessary for IE >= 10
                myWindow.print();
                myWindow.close();
            };
        }
    </script>
</head>
<body>
    <div id="myDiv">
        This will be printed.
        <img src="image.jpg"/>
    </div>
    <div>
        This will not be printed.
    </div>
    <div id="anotherDiv">
        Nor will this.
    </div>
    <input type="button" value="Print Div" onclick="PrintElem('#myDiv')" />
</body>
</html>

如果有人只是需要打印一个带有id的div,他不需要加载jquery

这里是做这件事的纯javascript代码

<html>
<head>
    <script type="text/javascript">
        function PrintDiv(id) {
            var data=document.getElementById(id).innerHTML;
            var myWindow = window.open('', 'my div', 'height=400,width=600');
            myWindow.document.write('<html><head><title>my div</title>');
            /*optional stylesheet*/ //myWindow.document.write('<link rel="stylesheet" href="main.css" type="text/css" />');
            myWindow.document.write('</head><body >');
            myWindow.document.write(data);
            myWindow.document.write('</body></html>');
            myWindow.document.close(); // necessary for IE >= 10

            myWindow.onload=function(){ // necessary if the div contain images

                myWindow.focus(); // necessary for IE >= 10
                myWindow.print();
                myWindow.close();
            };
        }
    </script>
</head>
<body>
    <div id="myDiv">
        This will be printed.
        <img src="image.jpg"/>
    </div>
    <div>
        This will not be printed.
    </div>
    <div id="anotherDiv">
        Nor will this.
    </div>
    <input type="button" value="Print Div" onclick="PrintDiv('myDiv')" />
</body>
</html>

我希望这能帮助到一些人

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');
}
