我需要每 5 分钟创建一个 ajax 调用。我必须在下面的代码。有人可以告诉我如何修改此代码以每 5 分钟运行一次 ajax 吗?

    $(document).ready(function() {
     var seriesOptions = [],
        yAxisOptions = [],
        colors = Highcharts.getOptions().colors;


        $.ajax({
                    url: 'echo_file.php', 
                    datatype: 'json',
                    success: function(data) {

                        seriesOptions=data;
                        createChart();
                    },

                    cache: false    
                    });

       function createChart() {

At the simplest level, put your AJAX call into a function, then create an interval:

在最简单的层面上,将您的 AJAX 调用放入一个函数中,然后创建一个间隔:

setInterval(ajaxCall, 300000); //300000 MS == 5 minutes

function ajaxCall() {
    //do your AJAX stuff here
}
