I am Displaying mask images & allowing user to upload the custome image inside mask image, now i want to give an option for user to Edit & Delete the Uploaded image....
Video link : https://drive.google.com/file/d/158RCO_NaXUg9KWOKSX6_SQ5r0CYF40oK/view
For that I need to create Pop up box once user click on Edit button, Also in the pop up i need to give an option to zoom, rotate the uploaded images....
for these i need to add lot of html code in future inside jquery, so is this is good way ? because i dont want to right more html code inside jquery as it looks bad when reading....
$("<span class="pip">" +
"<br/><span id="open" class="edit">Edit </span>" +
"<br/><span class="remove">Remove </span>" +
"</span>").insertAfter("#fileup");
Or Is it possible to write Html code outside script ?

What is your requirement? and what you are trying to do from business/exercise point of view in this code? Your title is vague and therefore your question becomes harder to answer.

I am Displaying mask images & allowing user to upload the custome image inside mask image, now i want to give an option for user to Edit & Delete the Uploaded image....
Video link : https://drive.google.com/file/d/158RCO_NaXUg9KWOKSX6_SQ5r0CYF40oK/view
For that I need to create Pop up box once user click on Edit button, Also in the pop up i need to give an option to zoom, rotate the uploaded images....
for these i need to add lot of html code in future inside jquery, so is this is good way ? because i dont want to right more html code inside jquery as it looks bad when reading....
$("<span class="pip">" +
"<br/><span id="open" class="edit">Edit </span>" +
"<br/><span class="remove">Remove </span>" +
"</span>").insertAfter("#fileup");
Or Is it possible to write Html code outside script ?

You can write your Templates as plain HTML (invisible) and then clone, adapt and insert them as you want.
HTML5 has even an extra template tag: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/template
