打印DIV内容的最佳方法是什么?


当前回答

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;
}

从这里https://forums.asp.net/t/1261525.aspx

<html> 
<head>
    <script language="javascript">
        function printdiv(printpage) {
            var headstr = "<html><head><title></title></head><body>";
            var footstr = "</body>";
            var newstr = document.all.item(printpage).innerHTML;
            var oldstr = document.body.innerHTML;
            document.body.innerHTML = headstr + newstr + footstr;
            window.print();
            document.body.innerHTML = oldstr;
            return false;
        }
    </script>

    <title>div print</title>

</head>

<body>
    //HTML Page //Other content you wouldn't like to print
    <input name="b_print" type="button" class="ipt" onClick="printdiv('div_print');" value=" Print ">

    <div id="div_print">
        <h1 style="Color:Red">The Div content which you want to print</h1>
    </div>
    //Other content you wouldn't like to print //Other content you wouldn't like to print
</body>    
</html>

将Element传递给这个函数打印:

函数printElm(elm) { var orig = document.body.innerHTML; document.body.innerHTML = elm.outerHTML; print (); document.body.innerHTML = origin; }

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。

最好的方法是将div的内容提交给服务器,并打开一个新窗口,服务器可以将这些内容放入新窗口中。

如果这不是一个选项,你可以尝试使用客户端语言,如javascript隐藏页面上的所有内容,除了div,然后打印页面…
