一款前端打印插件,可实现各个前端打印功能,并且跨浏览器。官网:[http://www.lodop.net/index.html]
(http://www.lodop.net/index.html)
基础用法
首先引入LodopFuncs.js文件,官网有下载,也可以下面直接复制
PRINT_INIT(strPrintTaskName)打印初始化
SET_PRINT_PAGESIZE(intOrient,intPageWidth,intPageHeight,strPageName)设定纸张大小
ADD_PRINT_HTM(intTop,intLeft,intWidth,intHeight,strHtml)增加超文本项
ADD_PRINT_TEXT(intTop,intLeft,intWidth,intHeight,strContent)增加纯文本项
ADD_PRINT_TABLE(intTop,intLeft,intWidth,intHeight,strHtml)增加表格项ADD_PRINT_SHAPE(intShapeType,intTop,intLeft,intWidth,intHeight,intLineStyle,intLineWidth,intColor)画图形
SET_PRINT_STYLE(strStyleName, varStyleValue)设置对象风格
PREVIEW打印预览
PRINT直接打印
PRINT_SETUP打印维护
PRINT_DESIGN打印设计

<body>
<div>
<a href="javascript:prn1_print()">直接打印</a>
</div>
<div id="print">
这里是会被打印出来的
</div>
</body>
<script> var LODOP; //声明全局变量 function prn1_print() { CreateOneFormPage(); LODOP.PRINT(); // 直接打印,不预览 }; function CreateOneFormPage() { LODOP = getLodop(); let strBodyStyle = "<style>" + document.getElementById("style2").innerHTML + "</style>" //打印内容的css let srtFormHtml = strBodyStyle + "<body>" + document.getElementById("print").innerHTML + "</body>" // id 为需要打印html部分的id LODOP.ADD_PRINT_RECT(0, 0, 800, 1100, 0, 1) LODOP.ADD_PRINT_HTM(0, 20, 800, 1100, srtFormHtml); //ADD_PRINT_HTML(0,0,0,0,'打印部分'),通过html方式打印出来 } </script>
以上是最基础的用法,vue框架同样可用,更复杂的话可以去官网查询用法,除了直接打印以外,还有预览打印等,以及其他控制打印的方法,功能还是挺多的,插件还是挺强大的,不过商用的话是需要买的,不然会有水印。
