Value is not getting set in CKEditor setData

Question

$(document).on('change', "input[name='child']", function() {
    CKEDITOR.config.contentsCss = 'lib/bootstrap/css/bootstrap.css', 'lib/css/myStyle.css';
    CKEDITOR.config.extraPlugins = 'font';
    var pjID = {};
    var pjDesc = [];
    $("input[name='child']:checked").each(function() {
        pjDesc.push($(this).val());
    });
    if ($(this).prop("checked") == true) {
        pjID.projectsk = $(this).val();            
        $.ajax({
            url: 'sample.php',
            type: 'POST',
            data: pjID,
            success: function(result) {
            var response = JSON.parse(result);                    
            var content = CKEDITOR.instances.projectEditor.getData();         
            CKEDITOR.instances.projectEditor.setData(content + response.data[0].project_desc);            
          },
            error: function(error) {
                console.log(error);
            }
        });
    }
    else if ($(this).prop("checked") == false) {              
        var content = "";
        var contentVal = "";           
        $.each(pjDesc, function(key, val) {
            pjID.projectsk = val;              
            $.ajax({
                url: 'sample.php',
                type: 'POST',
                data: pjID,                    
                success: function(result) {
                    var response = JSON.parse(result);
                    console.log(response);
                    content = response.data[0].project_desc;
                    contentVal = contentVal+"<br>"+content;
                    console.log(contentVal);               
                },
                error: function(error) {
                    console.log(error);
                }

            });
            console.log('contentVal',contentVal);
            CKEDITOR.instances.projectEditor.setData(contentVal);
        });
    }
    CKEDITOR.replace('projectEditor');
});

The above code completely works except for the this line CKEDITOR.instances.projectEditor.setData(contentVal);. I get the exact output in console. But I am not able to set the value in ckeditor. I have tried using insertHtml,insertText and also foocallback(). Kindly help me out

You have to place following code in success part of ajax. because your line execute first and data comes in variable after it.

 console.log('contentVal',contentVal);
 CKEDITOR.instances.projectEditor.setData(contentVal);

just place above lines below these lines

contentVal = contentVal+"<br>"+content;
console.log(contentVal);

your variable prints on console because of async behavior of ajax and java script. you can follow the post to understand: https://stackoverflow.com/a/23667087/2651863

I ma going to modify your code:

    $(document).on('change', "input[name='child']", function() {
        CKEDITOR.config.contentsCss = 'lib/bootstrap/css/bootstrap.css', 'lib/css/myStyle.css';
        CKEDITOR.config.extraPlugins = 'font';
// its better to initilize CKeditor immidiate after configuration
 CKEDITOR.replace('projectEditor');
        var pjID = {};
        var pjDesc = [];
        $("input[name='child']:checked").each(function() {
            pjDesc.push($(this).val());
        });
        if ($(this).prop("checked") == true) {
            pjID.projectsk = $(this).val();            
            $.ajax({
                url: 'sample.php',
                type: 'POST',
                data: pjID,
                success: function(result) {
                var response = JSON.parse(result);                    
                var content = CKEDITOR.instances.projectEditor.getData();         
                CKEDITOR.instances.projectEditor.setData(content + response.data[0].project_desc);            
              },
                error: function(error) {
                    console.log(error);
                }
            });
        }
        else if ($(this).prop("checked") == false) {              
            var content = "";
            var contentVal = "";           
            $.each(pjDesc, function(key, val) {
                pjID.projectsk = val;              
                $.ajax({
                    url: 'sample.php',
                    type: 'POST',
                    data: pjID,                    
                    success: function(result) {
                        var response = JSON.parse(result);
                        console.log(response);
                        content = response.data[0].project_desc;
                        contentVal = contentVal+"<br>"+content;
                        console.log(contentVal);  
                // set data when actually it arrive
                console.log('contentVal',contentVal);
                CKEDITOR.instances.projectEditor.setData(contentVal);             
                    },
                    error: function(error) {
                        console.log(error);
                    }

                });

            });
        }

    });
