isDOM: (typeof HTMLElement === 'object') ?
function (obj)
return obj instanceof HTMLElement;

function (obj)
return obj && typeof obj === 'object' && obj.nodeType === 1 && typeof obj.nodeName === 'string';

const MyPlugin =
MyPlugin.install = function (Vue, options)
// 4. 添加实例方法
Vue.prototype.$print = Print
export default MyPlugin
前端实现调动打印机部分打印界面

使用时直接引入js文件
<script type="text/JavaScript" src="path/to/jquery.print.js"></script>
<div id="ele"> <h1>印刷</h1> </div>
//使用时div的样式不可设置为隐藏,可先隐藏,执行打印方法时利用js切换显示效果,打印结束再隐藏
$("#ele").print(/*options*/); 或者使用下面的代码
$("#ele").print( globalStyles: true, mediaPrint: false, stylesheet: null, noPrintSelector: ".no-print", iframe: true, append: null, prepend: null, manuallyCopyFormValues: true, deferred: $.Deferred(), timeout: 750, title: null, doctype: ‘<!doctype html>‘ );
