打印DIV内容的最佳方法是什么?


当前回答

function printdiv(printdivname) {
    var headstr = "<html><head><title>Booking Details</title></head><body>";
    var footstr = "</body>";
    var newstr = document.getElementById(printdivname).innerHTML;
    var oldstr = document.body.innerHTML;
    document.body.innerHTML = headstr+newstr+footstr;
    window.print();
    document.body.innerHTML = oldstr;
    return false;
}

这将打印您想要的div区域,并将内容设置为原来的内容。Printdivname是要打印的div。

下面是一个适用于IE和Chrome的IFrame解决方案:

function printHTML(htmlString) {
    var newIframe = document.createElement('iframe');
    newIframe.width = '1px';
    newIframe.height = '1px';
    newIframe.src = 'about:blank';

    // for IE wait for the IFrame to load so we can access contentWindow.document.body
    newIframe.onload = function() {
        var script_tag = newIframe.contentWindow.document.createElement("script");
        script_tag.type = "text/javascript";
        var script = newIframe.contentWindow.document.createTextNode('function Print(){ window.focus(); window.print(); }');
        script_tag.appendChild(script);

        newIframe.contentWindow.document.body.innerHTML = htmlString;
        newIframe.contentWindow.document.body.appendChild(script_tag);

        // for chrome, a timeout for loading large amounts of content
        setTimeout(function() {
            newIframe.contentWindow.Print();
            newIframe.contentWindow.document.body.removeChild(script_tag);
            newIframe.parentElement.removeChild(newIframe);
        }, 200);
    };
    document.body.appendChild(newIframe);
}

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。

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');
}

这是我的jquery打印插件

(function ($) {

$.fn.printme = function () {
    return this.each(function () {
        var container = $(this);

        var hidden_IFrame = $('<iframe></iframe>').attr({
            width: '1px',
            height: '1px',
            display: 'none'
        }).appendTo(container);

        var myIframe = hidden_IFrame.get(0);

        var script_tag = myIframe.contentWindow.document.createElement("script");
        script_tag.type = "text/javascript";
        script = myIframe.contentWindow.document.createTextNode('function Print(){ window.print(); }');
        script_tag.appendChild(script);

        myIframe.contentWindow.document.body.innerHTML = container.html();
        myIframe.contentWindow.document.body.appendChild(script_tag);

        myIframe.contentWindow.Print();
        hidden_IFrame.remove();

    });
};
})(jQuery);
