make column data as hyperlink (dataTable JQUERY)

问题:

I am trying to make a column as hyperlink with datatable but no success.

function successCallback(responseObj){

  $(document).ready(function() {
         $('#example').dataTable( {
        "data":responseObj ,
        "bDestroy": true,
        "deferRender": true ,
        "columns": [
                    { "data": "infomation" },
                    { "data": "weblink" },
                ]
  } );

  } );

}

I need the weblink to display the link and be an hyperlink in that column so users can click and be redirected to another page. I looked into render but with less information there on links, i can't succeed to do it.

I also looked into this example but it wasn't very helpful.

回答1:

Use columns.render API method to dynamically produce content for a cell.

$('#example').dataTable({
   "data": responseObj,
   "columns": [
      { "data": "information" }, 
      { 
         "data": "weblink",
         "render": function(data, type, row, meta){
            if(type === 'display'){
                data = '<a href="' + data + '">' + data + '</a>';
            }

            return data;
         }
      } 
   ]
});

See this example for code and demonstration.

回答2:

    $('#example').dataTable( {
  "columnDefs": [ {
    "targets": 0,
    "data": "download_link",
    "render": function ( data, type, full, meta ) {
      return '<a href="'+data+'">Download</a>';
    }
  } ]
} );

From the documentation. It is quite clear and straightforward to me, what is it specifically that you do do not understand? What errors do you see?

If you are looking to add link based on other column data then can use the below approach.

$('#example').dataTable({
   "data": responseObj,
   "columns": [
      { "data": "information" }, 
      { 
         "data": "weblink",
         "render": function(data, type, row, meta){
            if(type === 'display'){
                data = '<a href="' + row.myid + '">' + data + '</a>';
            }
            return data;
         }
      } 
   ]
});

I have just changed the render function. data refers to only current column data, while row object refers to entire row of data. Hence we can use this to get any other data for that row.
