Wait until previous .append() is complete

Question

How can we make append wait until the previous append is complete. I am appending huge amount of data so the present append should check if the pre

Answer 1

Based on the answer from Tim Gard, I found this solution to be very elegant...

$(".selector").append(content).append(function() { /*code goes here to run*/ });

Answer 2

Unfortunately, the jQuery append() function does not include a callback. There is no way to really check for completion of it, as it supposedly happens immediately.

See Here for some info on how to use append efficiently. What it pretty much gets at is you can try to get all of your text into one variable and simply use append once.

[update] Since you have all your data in a JSON object from the get go, just do your looping through and put it all in a variable, then just append that once you're finished. [/update]

The below solution is working on all the browsers especially IE6. The response time in Firefox is 10 sec, but in IE6 it is 2 min 30 sec.

$('#printall1').click(function() {
    $('#fourElementsonly').empty();
    var cleartable = 0;
    var maxlimit = 0;
    var presentarraycount = 0;

    $.post("/PortalUserReport/getjunkdata", null, function(response, status) {
        var report = eval(response);// we have 6000 records in the report now
        var totalRecordsCount = report.length; // count = 6000 
        var totalRecordsCountfortheLoop = totalRecordsCount;
        var arraycount = Math.ceil(totalRecordsCount / 1000);
        var reports = new Array(arraycount); // reports[6]
        for (var i = 0; i < arraycount; i++) {
            $('#fourElementsonly').append('<table border = "1" id = "Portal_User_elements' + i + '" style = " border-collapse:collapse; width:800px; margin:0px; padding:0px; border-color:black"> </table>');
        }
        reports[presentarraycount] = "";
        $.each(report, function(x) {
            if (cleartable == 0) {
                for (var i = 0; i < arraycount; i++) {
                    $('#Portal_User_elements' + i).empty(); 
                }
                cleartable++;
            }

            if (recordnumber <= totalRecordsCountfortheLoop) {
                reports[presentarraycount] += "<tr style = \"height:20px;  border: 1px Solid Black\"> <td style = \"width:50px; text-align:center \"> " + recordnumber + " </td>   <td style = \"width:350px;\"> Name :" + report[x].FirstName + "</td> <td style = \"width:200px;\"> UserName :" + report[x].UserName + " </td> <td style = \"width:200px; \"> Company : " + report[x].Company + " </td> </tr>";
                reports[presentarraycount] += "<tr style = \"height:20px;  border: 1px Solid Black\"> <td > </td> <td> Registration Date : <label class = \"datepicker\"> " + report[x].ActiveDate + " </label> <td> User CN : " + report[x].UserCN + " </td> <td> Status: " + report[x].Status + " </td> </ td>  </tr>";
                reports[presentarraycount] += "<tr style = \"height:20px;  border: 1px Solid Black\"> <td> </td> <td> User Privilege : " + report[x].Privileges + " </td> <td> </td> </tr>";
                maxlimit++;
                if (maxlimit == 1000) {
                    presentarraycount++;
                    reports[presentarraycount] = "";
                    maxlimit = 0;
                }
            }
            recordnumber++;
        });

        for (var i = 0; i < arraycount; i++) {
            $('#Portal_User_elements' + i).append(reports[i]);
        }
    });
});
