Data lazy loading in DataTables 1.9

yzhang1121

Hi, Allen,

I saw your answer to an old discussion about lazy loading. You referred to this page: http://datatables.net/examples/server_side/pipeline.html. I copied the code to my file. It worked well. But I got an error:

TypeError: json.aaData is undefined

json.aaData.splice(0, iRequestStart - oCache.iCacheLower);

What do I miss something here? I am using Datatables 1.9.

Thank you for your help,

Yin

Please link to a test case showing the problem. I'm afraid I don't know what would cause that issue without guessing based on the limited information available. My best guess is that the JSON return doesn't have an aaData property, like the error says.

Allan,
Sorry for the delay. I looked into your code. If bNeedServer is true, my report is ok. No errors. But if bNeedServer is not true, the code goes to this branch:

json = jQuery.extend(true, {}, oCache.lastJson);
//console.log(oCache.lastJson);
json.sEcho = sEcho; /* Update the echo for each response */
json.aaData.splice(0, iRequestStart - oCache.iCacheLower);
json.aaData.splice(iRequestLength, json.aaData.length);
fnCallback(json);
return;

console.log(oCache.lastJson) returned undefined. What should I modify here?

Thanks,

Yin

Not sure I'm afraid. I'd need to see a test case to understand what is going wrong.
