javascript - Making URL, that keeps updating which is generated by span and id, clickable and opening in new tab -


i trying make url clickable , open in new window. how url being displayed , updated on html page:

python code:

def data_cb():     return jsonify(waiting=await_take_pic())

javascript code:

    jquery(document).ready(function() {         var tab = 1;          function update_values() {             $script_root = {{ request.script_root|tojson|safe }};             $.getjson($script_root+"/_data",                 function(data) {                     $("#waiting").text(data.waiting)                 });             if(tab == 1){                 settimeout(update_values, 3000);             }         }

html code:

<p>picture url update: <span id="waiting"></span></p>

this html line displays url keeps updating pictures being taken. if copy , paste url on new window can display picture.

i have tried sort of combinations , syntax make href, open.window, or onclick make url clickable , opens picture in new window haven't been successful (it needs taken http//...to end of link , placed appears). new python, javascript , html. in fact, first project working them need info , details possible when suggesting answers, please.tia

the easiest solution generate page url pre-set link:

 <p>picture <a href="url" target="_blank">url</a> update: <span id="waiting"></span></p>

this make url clickable , open in new window. can adjust image rotation code modify href attribute needed when image changes.

to make easier access link, add id attribute (e.g. <a id="imagelink" ...>) can set url like:

document.getelementbyid('imagelink').setattribute('href', url);
