Please help me any thing wrong in this code?...even i changed cache to false also getting same problem. if i type 1000/less or more lines data, always it is taking limited data. Please help me. thanks in Advance

Answer 1

I'd be willing to bet that your text has characters in it that are interfering with the url like "&", "?", "/", "=", etc.

You should encode your text with encodeURIComponent() like this:

var txtcategoryname=encodeURIComponent(tinyMCE.get('txtcategoryname').getContent());
var txttitle=encodeURIComponent($('#txttitle').val());
var selectError1=encodeURIComponent($("#selectError1").val());
var selectError2=encodeURIComponent($("#selectError2").val());
var selectError3=encodeURIComponent($("#selectError3").val());
