Deep_Secrets

Hi Please tell me What is wrong in my Code

 "columnDefs": [
                                        {

                                        "render": function (data, type, row) {
                                            if (row.Name == 'Student') {
                                                return row.UserName = "<a href='Userpage" + row.UserName + "')>" + row.UserName + "</a>";
                                            },
                                                if (row.Name == 'Admin') {
                                                return row.UserName = "<a href='Adminpage" + row.UserName + "')>" + row.UserName + "</a>";
                                              }   
                                            return data ;
                                        },
                                        "targets": [1,0]
                                    },

                                ]

---

Name | Group
user1 | StudentL')>Student

tangerine

return row.UserName = "<a href='Userpage" + row.UserName + "')>" + row.UserName + "</a>";

What is returned by that line?

Deep_Secrets

Col 1 is ok but It effects the col 2 (Group ).

Sets col1 value also to col 2

Deep_Secrets

Sorry it's if(row.type== or row.group

kthorngren

As Tangerine pointed out the return is incorrect. You don't want the row.UserName = on that line. Just return the html you want. Take a look at the forth example in the columns.render docs.

Then can you please tell me how I can add diffent links on username where the type matchs..
Eg add studentpage link to all usernames where Type/group is student..

kthorngren

Are you referring to this code?

                                               if (row.Name == 'Admin') {
                                               return row.UserName = "<a href='Adminpage" + row.UserName + "')>" + row.UserName + "</a>";
                                             }  

If so it should look like this:

                                               if (row.Name == 'Admin') {
                                               return "<a href='Adminpage" + row.UserName + "')>" + row.UserName + "</a>";
                                             }  

Notice I removed the row.UserName = from the return statement.

If this isn't your question then maybe you can put together a simple test case with an example of your data. This will allow use to more easily help you.

thanks, you are right but it will replace the content of col 2 with col 1 that means col 1 and col 2 data will be same where data matchs.

so to say but i want to check data from col 2 and add this link to col 1 is that possible

kthorngren

I'm not sure how to specifically help you without seeing an example with your data. The row parameter of columns.render contains the data for the row. You just need to setup your logic to use the row parameter in col1 to access the data of col2. But there isn't enough information here to actually understand your data structure, etc.

Please post a simple test case with an example of your data so we can help.

this is what i want

here is my tablehttps://codepen.io/DEEPSECRETS/project/editor/XmnBOG

All i want Username with Link and Type Must Not Be effected

kthorngren

Not sure I totally understand but based on your previous comments you don't want col1 and col2 to have the same link/value. However in you are running the same code for the two columns by using "targets": [0,1] in columnDefs. If you want different rendering for both columns then you should use different code for each. Maybe move them to the columns config like the cell and email columns.

For the Student column you say it must be Admin from ajax. Is this data returned in the ajax request?

Kevin

Deep_Secrets

I think you are not understanding me, let me clear you i want to add link to user name where result matches but col2 must not be effected
i request you please visi
t the link link again https://codepen.io/DEEPSECRETS/project/editor/XmnBOG

kthorngren

Like I said before if you want different results for the two columns then you should use different render functions. For col1 use the if (row.Type == 'Admin') { section but for col2 remove this if statement.

Another option is to include the meta parameter in the columns.render function. With this you can access the column index using meta.col. You can add this to this if statement, something like this if (row.Type == 'Admin' && meta.col === 0) {.
