issamymansour@gmail.comissamymansour@gmail.com Posts: 24Questions: 3Answers: 0

I am using the following code to make a link for a new page:-
columnDefs: [
{
targets: [2],
render: function ( data, type, row, meta ) {
if(type === 'display'){
data = '<a target="_blank" href="link.php?name=' + row[2] +'">' + data + ' </a>';
}

                        return data;
                    },

                },

            ],  

i need to get the column name instead of data.

regards

    I'm not sure what you mean by the name. Where are you defining the name? Do you mean columns.name? If so, I don't see it in the above code.

    Hi Allan,
    Thank you for your response, i am using the following dynamic code.

    var data,
    tableName= '#Dynamic',
    columns,
    str,
    jqxhr = $.ajax('test.php')
    .done(function () {
    data = JSON.parse(jqxhr.responseText);

                // Iterate each column and print table headers for Datatables dynamic_Account_Analysis.php
                $.each(data.columns, function (k, colObj) {
                    str = '<th>'+'<h5><center>' + colObj.name + '</center></h5>'+'</th>';
                    $(str).appendTo(tableName+'>thead>tr');
                });
    
    
                        // Debug? console.log(data.columns[0]);
    
                $(tableName).dataTable({
                    dom: 'Bfrtip',

    Thanks - however, I'm not actually clear on where the error is. Could you clarify where in the above code you are having a problem and what it is that you want it to do?

    Thanks,
    Allan

    in line 36 above code it give me "undefined "
    i want have the column name or row[number] both are the same error

  • allanallan Posts: 43,572Questions: 1Answers: 5,708 Site admin

    data = '<a target="_blank" href="test.php?screen_name=' + screen_name +'&data_type=' + columns.name +'">' + data + ' </a>'

    Is the line with the error.

    My guess is that you need to use columns[1] to get the data, since your data source appears to be arrays, not objects. Its difficult to say without a test case, but there is no columns.data option, which suggests that it is an array data source.

    test number 1:-
    this is the error message after using columns[2] :-

    Notice: Undefined index: column "in line number"

    Yes the data source is array correct

    test number 2:
    modify code using

    columns.data

    not working

  • Tester2017Tester2017 Posts: 94Questions: 14Answers: 10

    With console.log you can see what columns is and what it contains. Just put this line console.log('columns = ' + columns); before your line where filling data with a hyperlink.

  • issamymansour@gmail.comissamymansour@gmail.com Posts: 24Questions: 3Answers: 0

    I try the as following your code :-1:
    targets: 1,
    render: function ( data, type, row, meta ) {
    if(type === 'display'){
    console.log('columns = ' + columns);
    data = '<a target="_blank" href="Dynamic_tweets_report.php?screen_name=' + screen_name +'&data_type=' + data_type +'&column=25' +'&description=' + row[0] +'">' + data + ' </a>';
    }

    return data;
    },
    },

    No effect or any thing show in

    You are initializing your columns variable:

    var data,
    tableName= '#Dynamic',
    columns,
    

    But I don't see where you are populating it with anything. Maybe you need to add something like this to your loop that builds the table headers:
    columns.push(colObj.name);

    And change your variable init to this:

    var data,
    tableName= '#Dynamic',
    columns = [],

  • allanallan Posts: 43,572Questions: 1Answers: 5,708 Site admin

    Rather than us guessing about the full initialisation and data, please post a link to a test case showing the issue so we can help to debug the live running code.

    Answer ✓

    &description=' + row[1]

    Should be:

    &description=' + row.Description
    

    Your data object is an object not an array.
