javascript - Execute a src script inserted with .innerHTML -

-

i'm working on blogger. have function (showmusic, takes json code parameter) show posts , i'm calling this:

<script src='/feeds/posts/default/-/album/pop?max-results=20&orderby=published&alt=json-in-script&callback=showmusic'></script>

i'm looking way change labels ("album" , "pop") <select> tags , need insert script innerhtml, script doesn't execute:

function myfunction(label1,label2) {   var label1 += "/";   var label2 += "/";   var script = "\x3cscript src='/feeds/posts/default/-/"+label1+label2+"?max-results=20&amp;orderby=published&amp;alt=json-in-script&amp;callback=showmusic'>\x3c/script>"   document.getelementbyid("my-container").innerhtml = script; }

try out: 

function myfunction( label1, label2 ) {     var s = document.createelement( "script" );     s.type = "text/javascript";     s.async = true;     s.src = "/feeds/posts/default/-/" + label1 + label2 + "?max-results=20&amp;orderby=published&amp;alt=json-in-script&amp;callback=showmusic";     document.getelementbyid( "my-container" ).appendchild( s ); }

i'm made simple test. create html page content: 

<!doctype html> <html>     <head>         <title>test</title>         <script type="text/javascript">             function getjavascript() {                 var s = document.createelement( "script" );                 s.type = "text/javascript";                 s.async = true;                 s.src = "get_javascript.js";                 document.getelementbyid( "javascriptholder" ).appendchild( s );             }         </script>     </head>     <body>         <button type="button" onclick="getjavascript();">get javascript</button>         <div id="javascriptholder"></div>     </body> </html>

and file get_javascript.js this: 

alert( 'i javascript' );

and when click on button works charm.
