AJAX呼叫未发送成功响应

Question

//MAKE AJAX CALL TO REPOPULATE TABLE
        var newData = 'page_number=1&type=2';

        $.ajax({
            type: 'POST', // HTTP method POST or GET
            url: 'http://www.myurl.net/form_validate.php', //Where to make Ajax calls
            dataType:'text', // Data type, HTML, json etc.
            data:newData, //post variables
            success:function(response){

                //REFORMAT UPON SUCCESSFUL AJAX CALL
                alert(response);

            },
            error:function (xhr, ajaxOptions, thrownError){
                alert(xhr + " " + ajaxOptions + " " + thrownError); //throw any errors
            }
        });

All I've put in my PHP file is:

<?php echo "test"; ?>

When I go straight to that file, it echoes 'test.' When I try to run the AJAX function on the click of a button it gives me the error:

[object Object] error 

in an alert window. I've put the absolute URL to the file because I was thinking that the relative linking I was using was wrong but it now seems like it's some other issue. Am I overlooking a simple syntax error? Sorry if this is super basic but I can't seem to figure this out after working on it for a really long time. Thanks for your help.

Answer 1

The problem is your absolute url . Some browsers have problems dealing with absolute urls, consider it as a cross-domain request and block it even if it's not a cross-domain request . You should try with relative url instead

Answer 2

The problem might be in the url , try with relative path instead of absolute. You named the file was in the same folder as the .js file, so try

url: '/directory_path_to_the_same_folder_as_the_JS_file/form_validate.php',

Answer 3

Try using done with jQuery.post instead .

For example:

jQuery.post('form_validate.php', data).done(
        function(data, textStatus, jqXHR) {
                            alert(jqXHR.responseText);

        }).fail(function(jqXHR, textStatus, errorThrown) {
                    alert(jqXHR.responseText);

}).complete(function() {
    // Common code when request completes
});

Answer 4

• If your error is [object Object] error NOT FOUND then the reason is the specified url in AJAX is not correct.

• If your error is [object Object] error INTERNAL SERVER ERROR , its because of the error in your server file ie the php file ,error like variables not defined correctly etc..

• Some times error may occur due to cross domain, if you have not specified headers when in case your php file is not in the same domain

Hope this helps

Thank you

function abc(){
  var ret=true;
 $.ajax({
           type: 'POST',
           url: 'send_password.php',
           data: 'mail_to=mymail&new_password=pwd',
           async:false,
           success: function(response){

           },
           error: function(r){

               ret=false;
           }
       });
return ret;
}

    alert(abc());
