                yAxis: {
                    title: {
                        text: 'IDR'
                    },
                },

                },
                series: [{
                    showInLegend: false,
                    name: 'Daily',
                    data: [
                        1,2
                    ]
                }]
            };
            var obj = {},
            exportUrl = options.exporting.url;
            obj.options = JSON.stringify(options);
            obj.type = 'image/png';
            obj.async = true;

            var link=$.ajax({
                type: 'post',
                url: exportUrl,
                data: obj,
                dataType: 'html',
                context: document.body,
                global: false,
                async:false,

                success: function (data) {
                    var result=exportUrl+data;
                    return result;
                }
            }).responseText;
            $.ajax({
                        type: 'get',
                        url: 'http://webserver2/index.php/report/render?link='+link+'&id=1',
                        data: link,
                        success: function (data2) {
                            //alert(data2); 
                        }
                    });
});
</script>

If i execute it in my browser i will get file highcart.png to my server. But if i execute in cronjobs i get nothing. Any body know how to execute it with cronjobs??

Answer 1

JavaScript is a client-side language that runs from within a browser. You can however use something like PhantomJS to run js from the server side. Look at: http://phantomjs.org/

Edit:

Download the necessary package from here. Note that these are pre-compiled packages, we will assume you are using Linux.

You simply save the 'phantomjs' file in your filesystem somewhere (that you can access with crontab).

Save your javascript as a .js file extension.

Add a cron job like:

30 08 10 06 * /path/to/phantomjs javscriptfile.js

This will run 30 of June at 8.30am (You will need to schedule it when you want.)

Hopefully this should work as intended, although it does seem you are using jQuery functions so you might need to include the jQuery source code in your .js file.
