fnClick not working in TableTools button defintion

marcfarrow

Consider the following code. The CSV button works fine and generates a random filename. However, if the "fnClick" attribute is left in the extended PDF button properties, the Save As dialog does not appear.

[code]
TableTools.DEFAULTS.aButtons = [
{
"sExtends": "xls",
"fnClick" : function (nButton, oConfig, flash) {
if (parent && parent.OSDIndex) {
var newfilename = parent.OSDIndex.getSaveAsFilename(nButton, "csv");
if (newfilename != null) {
flash.setFileName(newfilename);
}
}
}
},
{
"sExtends" : "pdf",
"sPdfOrientation" : "landscape",
"sPdfSize" : "letter",
"fnClick" : function (nButton, oConfig, flash) {
if (parent && parent.OSDIndex) {
var newfilename = parent.OSDIndex.getSaveAsFilename(nButton, "pdf");
if (newfilename != null) {
/* using a debugger I have verified that the filename here is valid */
flash.setFileName(newfilename);
}
}
return true;
}
}
];
[/code]

Anyone have any thoughts on this?

Thanks.

In the simplest form, just adding the "fnClick" method to the PDF extension button, causes the dialog to stop working. Can anyone offer any suggestions?

Thanks.


[code]
if (typeof(TableTools) === "function") {
TableTools.DEFAULTS.sSwfPath = "/vsjs/jQuery/v1_8_2/plugins/TableTools-2_0_1/media/swf/copy_cvs_xls_pdf.swf";
TableTools.DEFAULTS.aButtons = [
{
"sExtends": "xls",
"fnClick" : function (nButton, oConfig, flash) {
if (parent && parent.OSDIndex) {
var newfilename = parent.OSDIndex.getSaveAsFilename(nButton, "csv");
if (newfilename != null) {
this.fnSetText(flash, newfilename)
// flash.setFileName(newfilename);
}
}
}
},
{
"sExtends" : "pdf",
"sPdfOrientation" : "landscape",
"sPdfSize" : "letter"
,
"fnClick" : function (nButton, oConfig, flash) {
}
}
];
}
[/code]

You are effectively replacing the default fnClick by doing that, so you need to replicate the logic that is used by default to get the 'Save as' box:

Fair enough, but why does the XLS behavior work, but the PDF doesn't?

I will look at this code and implement it.

Thanks Allan!

Ignore that last question Allan. I took your link above and looked at the implementations for XLS and also PDF and I understand why the XLS worked and the PDF doesn't. Either way, thanks for the response as you have me on the correct path now.

When the PDF and XLS buttons are clicked, it always presents the Save As Dialog box. Is there a setting (or some other way) to just "view" the document directly without saving to disk?

Thanks.
