方法一:
html代码:
在要打印的内容上加入:<!--startprint-->
和<!--endprint-->
js代码:
$('.printData').click(function(){bdhtml=window.document.body.innerHTML; sprnstr="<!--startprint-->"; eprnstr="<!--endprint-->"; prnhtml=bdhtml.substr(bdhtml.indexOf(sprnstr)+17); prnhtml=prnhtml.substring(0,prnhtml.indexOf(eprnstr)); window.document.body.innerHTML=prnhtml; window.print();})
去除打印按钮,在css中加入:
@media print {.noprint{display: none;}}
方法二:
<buttonn>打印</buttton><div id="print">
<!-- 要打印的内容 -->
<div>
$('.printData').click(function(){
// document.getElementById('print')获取需要打印区域的id名// innerHTML 属性设置或返回表格行的开始和结束标签之间的 HTML。let newstr = document.getElementById('print').innerHTML;console.log(newstr)window.document.body.innerHTML = newstr;let oldstr = window.document.body.innerHTML;// 实现打印功能window.print();window.location.reload(); //解决打印之后按钮失效的问题window.document.body.innerHTML = oldstr;return false;
})
方法三:lodop 官网:http://www.lodop.net/index.html
- 语法:更详细的可以戳 “这里”
(1) PRINT_INIT(strPrintTaskName)打印初始化
(2)SET_PRINT_PAGESIZE(intOrient,intPageWidth,intPageHeight,strPageName)设定纸张大小
(3)ADD_PRINT_HTM(intTop,intLeft,intWidth,intHeight,strHtml)增加超文本项
(4) ADD_PRINT_TEXT(intTop,intLeft,intWidth,intHeight,strContent)增加纯文本项
(5) ADD_PRINT_TABLE(intTop,intLeft,intWidth,intHeight,strHtml)增加表格项
(6) ADD_PRINT_SHAPE(intShapeType,intTop,intLeft,intWidth,intHeight,intLineStyle,intLineWidth,intColor)画图形
(7)SET_PRINT_STYLE(strStyleName, varStyleValue)设置对象风格
(8)PREVIEW打印预览
(9)PRINT直接打印
(10)PRINT_SETUP打印维护
(11)PRINT_DESIGN打印设计 - 去下载中心下载案例,保留 js 文件。
- 我这里用在 vue 项目中,所以要对 js 进行改造。感谢一下https://www.jianshu.com/p/d288963c1a80提供的代码

}
- 把它放到 src 下的 plugs 文件夹中,在需要用的页面中引入
import {getLodop} from '@/plugs/vuePrint/LodopFuncs.js'
5.要注意的是,lodop 不能读取外部样式
