由于公司开发需要再查看word pdf Excel 插件中插入自定义的签署水印解决办法如下： function watermark(settings) { //默认设置 var defaultSettings={ watermark_txt:”text”, watermark_x:0,//水印起始位置x轴坐标 watermark_y:20,//水印起始位置Y轴坐标 watermark_rows:400,//水印行数 watermark_cols:700,//水印列数 watermark_x_space:100,//水印x轴间隔 watermark_y_space:50,//水印y轴间隔 watermark_color:’#000000’,//水印字体颜色 watermark_alpha:0.3,//水印透明度 watermark_fontsize:’45px’,//水印字体大小 watermark_font:’微软雅黑’,//水印字体 watermark_width:10,//水印宽度 watermark_height:70,//水印长度 watermark_angle:25//水印倾斜度数 }; //采用配置项替换默认值，作用类似jquery.extend if(arguments.length===1&&typeof arguments[0] ===”object” ) { var src=arguments[0]||{}; for(key in src) { if(src[key]&&defaultSettings[key]&&src[key]===defaultSettings[key]) continue; else if(src[key]) defaultSettings[key]=src[key]; } }
