javascript for循环的问题不在每次执行时

Question

I'm using this JavaScript code for alert count in an array of pages.

urls is an array of page names, and count is the count value.

I want to alert the count value in each pages of the array urls.

But the for loop is not executing all time. I don't know what happens... Any body please help me to find out the mistake..

Am using echo $_POST['suggest']; in the array of pages. But i want to use JavaScript code for receiving the value of suggest and alert it. How to receive the value using JavaScript?

<script>
        $(document).ready(function () {
            var count = document.getElementById('display_visitor_number').innerHTML; //count
            var urls = document.getElementById('display_visitor_urls').innerHTML; //array of page names
            var myarr = urls.split(",");

            for (var i=1;i<myarr.length;i++)
            { 
                $.post(myarr[i],{suggest:count}, function(data) {
                    alert(data);
                });
            }


        });
    </script>

Answer 1

if the string urls starts with , before you split it will have an empty string as first value (this will cause jquery to make an ajax call for the current page) you may want to check for that and start with 0

<script>
        $(document).ready(function () {
            var count = document.getElementById('display_visitor_number').innerHTML; //count
            var urls = document.getElementById('display_visitor_urls').innerHTML; //array of page names
            var myarr = urls.split(",");

            for (var i=0;i<myarr.length;i++)
            { 
                if(myarr[i] !== '')$.post(myarr[i],{suggest:count}, function(data) {
                    alert(data);
                });
            }


        });
    </script>

instead of using split function you'd better try RegExp and match all non-space character sequences. replace

var myarr = urls.split(",");

with

var myarr = urls.match(/[^ ,]+/g)

and you should start you for loop with var i=0 then.
