Modify DataTables TableTools default PDF export filename at runtime
提问by Chris
I am using JQuery DataTables TableTools plugin and am defining a default filename for the PDF. However, I am using datatables with ajax, and have a date range selector, so the page isnt refreshed and therefore I am unable to provide a new default filename when then criteria changes.
我正在使用 JQuery DataTables TableTools 插件并为 PDF 定义默认文件名。但是，我使用带有 ajax 的数据表，并且有一个日期范围选择器，因此页面不会刷新，因此当条件更改时我无法提供新的默认文件名。
Does anyone know how I can change the default filename at runtime, after datatables has been initialized with table tools, i.e modify the config directly?
有谁知道如何在运行时更改默认文件名，在使用表工具初始化数据表后，即直接修改配置？
"oTableTools": {
"sSwfPath": "js/DataTables/copy_cvs_xls_pdf.swf",
"aButtons": [
"copy",
"csv",
"xls",
{
"sExtends": "pdf",
"sTitle": "Report Name",
"sPdfMessage": "Summary Info",
"sFileName": "<?php print('How do i use jquery to change this after the table has been initialized'); ?>.pdf",
"sPdfOrientation": "landscape"
},
"print"
]
}

I guess you want some dynamically generated name. Create a function that returns the (string) file name.
我猜您想要一些动态生成的名称。创建一个返回（字符串）文件名的函数。
function getCustomFileName(){
var docDate = $("#from").val();
var filter = $("#example_filter input").val();
var oSettings = oTable.fnSettings();
var fileName = docDate+"_"+filter;
return fileName;
}
And use the function inside $(document).readybut outside $('#dTable').dataTable({ }).
并使用内部$(document).ready但外部的功能$('#dTable').dataTable({ })。
"oTableTools": {
"sSwfPath": "js/DataTables/copy_cvs_xls_pdf.swf",
"aButtons": [
"copy",
"csv",
"xls",
{
"sExtends": "pdf",
"sTitle": "Report Name",
"sPdfMessage": "Summary Info",
"sPdfOrientation": "landscape"
"fnClick": function( nButton, oConfig, flash )
{
customName = getCustomFileName()+".pdf";
flash.setFileName( customName );
this.fnSetText( flash,
"title:"+ this.fnGetTitle(oConfig) +"\n"+
"message:"+ oConfig.sPdfMessage +"\n"+
"colWidth:"+ this.fnCalcColRatios(oConfig) +"\n"+
"orientation:"+ oConfig.sPdfOrientation +"\n"+
"size:"+ oConfig.sPdfSize +"\n"+
"--/TableToolsOpts--\n" +
this.fnGetTableData(oConfig)
);
}
},
"print"
]
}
