为什么我的脚本没有将值传递给PHP？

I want to get the value of an href using java script and then pass it to another file of php, I did the code of JS and some friend add J query to it, in order to pass the value to the test.php file, but I don't why it is not working.

<script>
$(function(){
    $('div#tabs ul li a').click(function() {
    var n = $(this).attr('href');
    var p=n.slice(5,6); 
    alert(p);
     $.ajax({
        type: 'post',
        url: 'test.php'
        data: {value : p}
        success: function(data) {
            //do something with response 'data'
        }

});
});
</script>

You're missing a final }); (and a few commas) in your code example. It should look like this:

<script>
$(function(){
    $('div#tabs ul li a').click(function() {
        var n = $(this).attr('href');
        var p = n.slice(5, 6);
        alert(p);
        $.ajax({
            type: 'post',
            url: 'test.php',
            data: {value : p},
            success: function(data) {
                // Do something with response 'data'
            }
        });
    });
});
</script>

When creating a set in javascript, the key/value pairs need commas:

<script>
$(function(){
    $('div#tabs ul li a').click(function() {
    var n = $(this).attr('href');
    var p=n.slice(5,6); 
    alert(p);
     $.ajax({
        type: 'post',
        url: 'test.php',
        data: {value : p},
        success: function(data) {
            //do something with response 'data'
        }

});
});
});
</script>
