jquery - Pass Golang Variables into Javascript -


i trying pass golang variables javascript file. have read multiple articles online, including how pass variables , data php javascript?. feel i'm pretty close, alas eloquent implementation problem eludes me.

i'm looking simple , elegant solution injects object value in go variable in javascript. feel common problem, lack of clear tutorial on surprises me.

my first file [server.go] servers html page using templating libraries in golang passing in context , serving them through handlers. 

type passstruct struct{     data    []int     number1 int     number2 int }  //inject structure render func render(w http.responsewriter, tmpl string, context context){        //parse context , fill in templating variables using template   }

i have html document served, adds javascript file it. 

 <html>      <head>      //import javascript file       </head>      <body>      //some body      </body>  </html>

finally, javascript file interested in: 

  var data; //some    var number1;   var number2;    function dosomething(){   }

i need send passstruct javascript file, , map out each of values within structure variable in javascript file. have tried ajax calls, have not had success far.

this way maybe helpful:

html:

<html>     <head>      <!--import javascript file -->         <script type="text/javascript" src="static/myjs.js"></script>         <script type="text/javascript">             myfunc({{.}});         </script>      </head>      <body>      <!--some body-->      </body> </html>

javascript:(myjs.js)

function myfunc(passstruct){     var obj = object();      var data = passstruct.data;     var number1=passstruct.number1;     var number2=passstruct.number2;      obj.data=data;     obj.number1=number1;     obj.number2=number2;      return obj;  }

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. :)
