i have a problem about this, i want to get the array length of my array data so that i can use it in my loop. Why i am not getting it by using this code : var arrayLength = myclinicsID.length; , i declared myclinicsID in a global variable and i also push data with other function and then now, i want to get the length of that array so that i can use it with my loop, now here is my full code:

function getbarxAxis() {
  getallclinics();
  var arrayLength = myclinicsID.length;
 $.ajax({
   url: siteurl+"patients_report/bardata_date",
   type: "POST",
   dataType: "JSON",
   success: function(data) {
     for (var i in myclinicsID) {
       categories.push(data[i]["datemonths"]);

          for(var innerLoop = 0; innerLoop < arrayLength; i++) {
            //getbarSeriesData(myclinicsID[innerLoop],data[i]['datemonths']);
          }
     }
   }
 });
}

here is my getallclinics(); full code where i populate the myclinicsID array:

function getallclinics() {
   $.ajax ({
          url: siteurl+"patients_report/seriesclinics",
          type: "POST",
          dataType: "JSON",
          success: function(data) {
            for(var i in data) {
              myclinicsNAME.push(data[i]['clinic_name']);
              myclinicsID.push(data[i]['clinic_id']);
            }
          }
   });
}

Are you sure your AJAX call succeeds? – Gibbs Apr 25 '17 at 05:23
hmm how can i make sure of it? @GopsAB please help me – Jc John Apr 25 '17 at 05:24
Add a Error call back and have a break point if u r using IDE or else use console.log. – Gibbs Apr 25 '17 at 05:25
Try to see `data` in console inside `success`. – Mamun Apr 25 '17 at 05:26
POST XHR http://localhost/clinic/patients_report/seriesclinics @Mamun – Jc John Apr 25 '17 at 05:28
how can i do that @GopsAB sorry sir, just a beginner – Jc John Apr 25 '17 at 05:28
Most probably it tries to get `myclinicsID.length` not waiting for `ajax` response of `getallclinics()` – kzharas210 Apr 25 '17 at 05:30
@kzharas210 yes sir, i think that is what happened, how can i avoid it ? – Jc John Apr 25 '17 at 05:34
@kzharas210 how can i be sure that my first function was finished before running my ajax ? – Jc John Apr 25 '17 at 05:35
@JcJohn You need a synchronous `ajax` execution by specifying `async: false`. – kzharas210 Apr 25 '17 at 05:40
@kzharas210 . can you give me some example so that i can follow with that? . a very simple to understand please. i am just a beginner – Jc John Apr 25 '17 at 05:43
@JcJohn try `dataType: "JSON", async: false, success: function(data) {` – kzharas210 Apr 25 '17 at 05:46
@kzharas210 in what function would i put that? at first or at second? – Jc John Apr 25 '17 at 05:48
@JcJohn inside `getallclinics()` – kzharas210 Apr 25 '17 at 05:48
@kzharas210 so, you mean, i will only add async: false? – Jc John Apr 25 '17 at 05:51
@JcJohn yes, only that – kzharas210 Apr 25 '17 at 05:53
@kzharas210 thanks, can you explain me why? and whats wrong if i didn't add async: false? . i need to know what was happen. – Jc John Apr 25 '17 at 05:55
