How do I display a JavaScript variable inside my HTML tags in JSP? -


i have function gets original string , slice it. how display results in html?

function parsingfunction() {     var originalstring = entity.getgenresolr();     var results = originalstring.slice(1, -1);     return results;  } </script> <div class = "option_title_summary_summary"> <p>genre list: ${parsingfunction}</p>

well code using incorrect because can't update html javascript variables way, have update html javascript instead.

your code this:

function parsingfunction() {    /*var originalstring = entity.getgenresolr();    var results = originalstring.slice(1, -1);    return results;*/    return ["aaa", "bbb", "ccc"].join(" -- ");  }    document.getelementbyid("genrelist").textcontent = "genre list: " + parsingfunction();
<div class="option_title_summary_summary">    <p id="genrelist"> </p>

i commented old code avoid exceptions undefined variables , gave id="genrelist" paragraph can in js code.

note:

there's solution it's not recommended in javascript, using document.write():

<script>    function parsingfunction() {      /*var originalstring = entity.getgenresolr();      var results = originalstring.slice(1, -1);      return results;*/      return ["aaa", "bbb", "ccc"].join(" -- ");    }  </script>  <div class="option_title_summary_summary">    <script>      document.write('<p> genre list: ' + parsingfunction() + '</p>');    </script>
