Html code as IFRAME source rather than a URL

Question

This standard code for an IFRAME  is there a way to replace the src URL with Just html code  so my problem is simple  I have a page it loads an HTML body from MYSQL I want to present that code in a frame so it renders it self independent of the rest of the page and in the confines of that specific bordering    lt iframe src  http   example com  name  test  height  120  width  600  gt You need a Frames Capable browser to view this content  lt  iframe gt

iframe srcdoc  This attribute contains HTML content  which will override src attribute  If a browser does not support the srcdoc attribute  it will fall back to the URL in the src attribute  Let s understand it with an example  lt iframe      name  quot my iframe quot       srcdoc  quot  lt h1 style  text-align center  color  9600fa  gt Welcome to iframes lt  h1 gt  quot      src  quot https   www birthdaycalculatorbydate com  quot      width  quot 500px quot      height  quot 200px quot   gt  lt  iframe gt   Original content is taken from iframes

You can do this with a data URL   This includes the entire document in a single string of HTML   For example  the following HTML    lt html gt  lt body gt foo lt  body gt  lt  html gt    can be encoded as this   data text html charset utf-8  3Chtml 3E 3Cbody 3Efoo 3C body 3E 3C html 3E   and then set as the src attribute of the iframe   Example     Edit  The other alternative is to do this with Javascript   This is almost certainly the technique I d choose   You can t guarantee how long a data URL the browser will accept   The Javascript technique would look something like this   var iframe   document getElementById  foo        iframedoc   iframe contentDocument    iframe contentWindow document   iframedoc body innerHTML    Hello world     Example    Edit 2  December 2017   use the Html5 s srcdoc attribute  just like in Saurabh Chandra Patel s answer  who now should be the accepted answer  If you can detect IE Edge efficiently  a tip is to use srcdoc-polyfill library only for them and the  pure  srcdoc attribute in all non-IE Edge browsers  check caniuse com to be sure     lt iframe srcdoc   lt html gt  lt body gt Hello   lt b gt world lt  b gt   lt  body gt  lt  html gt   gt  lt  iframe gt

According to W3Schools  HTML 5 lets you do this using a new  srcdoc  attribute  but the browser support seems very limited

I have a page it loads an HTML body from MYSQL I want to present that code in a frame so it renders it self independent of the rest of the page and in the confines of that specific bordering   An object with a unencoded  dataUri might have also fit your need if it was only to load a portion of data text   The HTML  lt object gt  element represents an external resource  which can be treated as an image  a nested browsing context  or a resource to be handled by a plugin    x000D   x000D  body  display flex min-height 25em   p  margin auto   object  margin 0 auto background lightgray   x000D   lt p gt here My uploaded content   lt  p gt   lt object data  data text html     lt style gt    table     display  table    text-align center    width 100     height 100       table  gt        display  table-row      table  gt  main     display  table-cell    height  100     vertical-align  middle     lt  style gt     lt div class  table  gt     lt header gt       lt h1 gt Title lt  h1 gt       lt p gt subTitle lt  p gt     lt  header gt      lt main gt       lt p gt Collection lt  p gt       lt p gt Version lt  p gt       lt p gt Id lt  p gt     lt  main gt      lt footer gt       lt p gt Edition lt  p gt     lt  footer gt   gt    lt  object gt  x000D   x000D   x000D   But keeping your Iframe idea  You could also load your HTML inside your iframe tag and set it  as the srcdoc value You should not have to mind about quotes nor turning it into a dataUri but only mind to fire onload once   The HTML Inline Frame element   lt iframe gt   represents a nested browsing context  embedding another HTML page into the current one   Both iframe below will render the same  one require extra javascript  example loading a full document    x000D   x000D  body     display  flex    min-height  25em     p     margin  auto     iframe     margin  0 auto    min-height  100     background lightgray    x000D   lt p gt here my uploaded contents   gt   lt  p gt     lt iframe srcdoc   lt  xml version  1 0  encoding  utf-8   gt   lt  DOCTYPE html PUBLIC  -  W3C  DTD XHTML 1 1  EN     http   www w3 org TR xhtml11 DTD xhtml11 dtd  gt    lt html xmlns  http   www w3 org 1999 xhtml  gt   lt head gt     lt title gt  lt  title gt     lt style gt  html  body     height  100     margin 0     body table     display  table    text-align center    width 100       table  gt        display  table-row      table  gt  main     display  table-cell    height  100     vertical-align  middle     lt  style gt   lt  head gt    lt body class  table  gt     lt header gt       lt h1 gt title lt  h1 gt       lt p gt injected via  lt code gt srcdoc lt  code gt  lt  p gt     lt  header gt      lt main gt       lt p gt Collection lt  p gt       lt p gt Version lt  p gt       lt p gt Id lt  p gt     lt  main gt      lt footer gt       lt p gt Edition lt  p gt     lt  footer gt   lt  body gt   lt  html gt   gt    lt  iframe gt      lt iframe onload  this setAttribute  srcdoc   this innerHTML  this setAttribute  onload       gt       lt  -- below html loaded -- gt       lt  xml version  1 0  encoding  utf-8   gt       lt  DOCTYPE html PUBLIC  -  W3C  DTD XHTML 1 1  EN         http   www w3 org TR xhtml11 DTD xhtml11 dtd  gt        lt html xmlns  http   www w3 org 1999 xhtml  gt        lt head gt         lt title gt Test lt  title gt         lt style gt          html          body             height  100             margin  0            overflow auto                             body table             display  table            text-align  center            width  100                               table gt               display  table-row                              table gt main             display  table-cell            height  100             vertical-align  middle                   lt  style gt       lt  head gt        lt body class  table  gt         lt header gt           lt h1 gt Title lt  h1 gt           lt p gt Injected from  lt code gt innerHTML lt  code gt  lt  p gt         lt  header gt          lt main gt           lt p gt Collection lt  p gt           lt p gt Version lt  p gt           lt p gt Id lt  p gt         lt  main gt          lt footer gt           lt p gt Edition lt  p gt         lt  footer gt       lt  body gt        lt  html gt       lt  iframe gt  x000D   x000D   x000D
