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>

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.

android - Unable to generate FCM token from dynamically instantiated Firebase -

our business logic requires instantiate firebase during runtime. fetch firebase credentials (app id, api key etc.) default firebase location after knowing user's public key , create firebase instance using credentials. this means there 2 firebase instances used within app: the default "index" firebase gives credentials second the actual firebase intend use point forward the second firebase initialised this: firebaseapp app = firebaseapp.initializeapp(<context>, <options>, <app_label>); our problem traditional method of retrieving fcm token using firebaseinstanceidservice , ontokenrefresh() fails since ontokenrefresh() method called first firebase instance. directly calling string token = firebaseinstanceid.getinstance(app).gettoken(); returns null never ready when called. have tried polling test if token generated @ point. no luck. how can generate fcm token reliably firebase instance instantiated during runtime? i...
