jquery - Ajax get column table value to become a variable in javascript -


i want column table value become variable in javascript complete formula: 10 * vhasil_m * 32.03* 1000 / 5.

i have query this:

select round(avg(cast(t_dtl.hasil_m decimal(6,4))),4) hasil_m t_hdr join  t_dtl on t_hdr.headerid = t_dtl.headerid id_solvent ='naoh' , status='ok' , concentrate='0.0100' , date_start <='2016-05-01' , date_finish >='2016-05-01'

the query result like:

| hasil_m     | | ----------- | | 0.0100      |

i want above column value become variable formula, vhasil_m.

to run query, i've created model:

function getdata_naoh($datetest){     $result = $this->db1->query("select round(avg(cast(t_dtl.hasil_m decimal(6,4))),4) hasil_m t_hdr join  t_dtl on t_hdr.headerid = t_dtl.headerid id_solvent ='naoh' , status='ok' , concentrate='0.0100' , date_start <='$datetest' , date_finish >='$datetest'");     if($result->num_rows()>0){         return $result->result_array();     }else{         return array();     } }

and controller executed it:

function get_naoh(){     $date_analysis = trim($this->input->post('date_analysis'));     $datetest = trim($this->input->post('date_analysis'));     $datetest = substr($datetest,6,4).'-'.substr($datetest,3,2).'-'.substr($datetest,0,2);      $dtnaoh = $this->m_tambahan->getdata_naoh($datetest);      foreach($dtnaoh $row){         $data1 .= $row[hasil_m];     }      $data =  $data1;     echo $data; }

then create ajax this:

<script type="text/javascript"> $(document).ready(function(){       $(document).on('change','.no_picno', function() {         var = $(this);         var dt_no = that.val();         console.log(that.next());         var col_date_analysis =  that.parent().prev().find('.date_analysis');         var date_analysis = col_date_analysis.val();          $.ajax({                   type :"post",                   url : "<?php echo base_url();?>index.php/additionals/file/c_utils/get_naoh",                   data : { date_analysis: date_analysis, no_picno: dt_no },                   success: function(data){                       // code here                   }         });     }); }); </script>

the ajax work without error, create javascript run formula:

<script type="text/javascript">     function gettotal() {         var obj = document.getelementsbytagname('input');            for(var i=0; < obj.length; i++) {           if (obj[i].name == "sulfur_vnaoh[]") {                var dt_sulfur_vnaoh = obj[i].value;           };           if (obj[i].name == "sulfur_ws[]") {                var dt_sulfur_ws = obj[i].value           };           if (obj[i].name == "sulfur_hasil[]") {             if ((dt_sulfur_ws != '')&&(dt_sulfur_vnaoh != '')) {                 var totalsulfur = 10*vhasil_m*32.03*1000/5;               obj[i].value = totalsulfur;             } else {                 obj[i].value = '';             };           };         }     }; </script>

how declare or initializing ajax result variable in javascript complete formula ?

thanks.

in ajax code need create global variable store data:

<script type="text/javascript"> $(document).ready(function(){       $(document).on('change','.no_picno', function() {         var = $(this);         var dt_no = that.val();         console.log(that.next());         var col_date_analysis =  that.parent().prev().find('.date_analysis');         var date_analysis = col_date_analysis.val();          $.ajax({                   type :"post",                   url : "<?php echo base_url();?>index.php/additionals/file/c_utils/get_naoh",                   data : { date_analysis: date_analysis, no_picno: dt_no },                   success: function(data){                       window.data=data;                   }         });     }); }); </script>

and after ajax call, fire gettotal() function, instead of using vhasil_m in formula use window.data:

<script type="text/javascript">     function gettotal() {         var obj = document.getelementsbytagname('input');            for(var i=0; < obj.length; i++) {           if (obj[i].name == "sulfur_vnaoh[]") {                var dt_sulfur_vnaoh = obj[i].value;           };           if (obj[i].name == "sulfur_ws[]") {                var dt_sulfur_ws = obj[i].value           };           if (obj[i].name == "sulfur_hasil[]") {             if ((dt_sulfur_ws != '')&&(dt_sulfur_vnaoh != '')) {                 var totalsulfur = 10*window.data*32.03*1000/5;               obj[i].value = totalsulfur;             } else {                 obj[i].value = '';             };           };         }     }; </script>

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
