pdf表單模板
js : 渲染出動態的html ,其實就是一個a標籤
Visitor.operateFormatter = function(value, row, index) { //編輯 var editButton = '<button type="button" class="btn btn-success btn-xs" onclick="Visitor.openUpdateVisitor(\'' + row.id + '\')" '; if($("#visitor_update").val() == undefined){ editButton += 'disabled="disabled"'; } editButton += '><i class="fa fa-edit"></i> 編輯</button>'; //刪除 var deleteButton = '<button type="button" class="btn btn-danger btn-xs button-margin" onclick="Visitor.delete(\'' + row.id + '\')" '; if($("#visitor_delete").val() == undefined){ deleteButton += 'disabled="disabled"'; } deleteButton += '><i class="fa fa-remove"></i> 刪除</button>'; //pdf下載 var pdfButton = '<a href="visitor/exportPDF/' + row.id + '" '; pdfButton += '> PDF</a>'; return [ editButton,deleteButton,pdfButton,].join(''); }
controller

maven 載入的jar包
<!--pdf 匯出需要的jar包 --> <dependency> <groupId>com.itextpdf</groupId> <artifactId>itextpdf</artifactId> <version>5.5.6</version> </dependency> <dependency> <groupId>com.itextpdf.tool</groupId> <artifactId>xmlworker</artifactId> <version>5.5.6</version> </dependency>

pdf檔案匯出進階版
1. pdf檔案網頁預覽
2.pdf檔案合併
3.刪除專案路徑的pdf
引入pdfjs
js:

//ids 是check 方法裡面把多個id 用都用隔開儲存的一個js屬性controller:
