How to post html data using jquery?

I need to grab a table's html and post it to a page where the table will be exported as xls, but I can't get it to work, I tried to pass the data as object, no luck, then I tried to pass it as string, still no luck (is it because the table too large?)

        //var tblReportResultData= "id=tblReportResult&name=tblReportResult&html=" + escape($("#tblReportResult").html()); //,
        var tbl开发者_如何学GoReportResultData = {id:"check",html:$("#tblReportResult").html()}

        $.ajax({
            url:'ajax.aspx',
            type:'POST',
            data:tblReportResultData,
            dataType:'html',
            success:function(msg){
                alert("waterver");
            },
            error: function(xhr, text, err){
                alert("Error:" + text);
            }                
        });

I found out the problem, it's because post html code could be dangerous and the system automatically blocked it, after I used escape(), it worked.
