Simply supplying the HTML of elements you want to add to a jQuery constructor     will return a jQuery object from newly built HTML  suitable for being appended into the DOM using jQuery s append   method   For example   var t       lt table cellspacing  0  class  text  gt  lt  table gt       append t     You could then populate this table programmatically  if you wished   This gives you the ability to specify any arbitrary HTML you like  including class names or other attributes  which you might find more concise than using createElement and then setting attributes like cellSpacing and className via JS

jQuery out of the box doesn t have the equivalent of a createElement   In fact the majority of jQuery s work is done internally using innerHTML over pure DOM manipulation   As Adam mentioned above this is how you can achieve similar results   There are also plugins available that make use of the DOM over innerHTML like appendDOM  DOMEC and FlyDOM just to name a few   Performance wise the native jquery is still the most performant  mainly becasue it uses innerHTML

Though this is a very old question  I thought it would be nice to update it with recent information   Since jQuery 1 8 there is a jQuery parseHTML   function which is now a preferred way of creating elements  Also  there are some issues with parsing HTML via     html code goes here     fo example official jQuery website mentions the following in one of their release notes      Relaxed HTML parsing  You can once again have leading spaces or   newlines before tags in   htmlString   We still strongly advise that   you use   parseHTML   when parsing HTML obtained from external   sources  and may be making further changes to HTML parsing in the   future    To relate to the actual question  provided example could be translated to   this  OuterDiv       parseHTML   lt div gt  lt  div gt          hide        append     parseHTML   lt table gt  lt  table gt              attr   cellSpacing   0             addClass  text             which is unfortunately less convenient than using just      but it gives you more control  for example you may choose to exclude script tags  it will leave inline scripts like onclick though     gt    parseHTML   lt div onclick  a  gt  lt  div gt  lt script gt  lt  script gt      lt div onclick   a  gt   lt  div gt      gt    parseHTML   lt div onclick  a  gt  lt  div gt  lt script gt  lt  script gt    document  true    lt div onclick   a  gt   lt  div gt     lt script gt   lt  script gt      Also  here s a benchmark from the top answer adjusted to the new reality   JSbin Link  jQuery 1 9 1       parseHTML     88ms       parseHTML   240ms    lt div  lt  div      138ms    lt div            143ms   createElement   64ms   It looks like parseHTML is much closer to createElement than      but all the boost is gone after wrapping the results in a new jQuery object

Simply supplying the HTML of elements you want to add to a jQuery constructor     will return a jQuery object from newly built HTML  suitable for being appended into the DOM using jQuery s append   method   For example   var t       lt table cellspacing  0  class  text  gt  lt  table gt       append t     You could then populate this table programmatically  if you wished   This gives you the ability to specify any arbitrary HTML you like  including class names or other attributes  which you might find more concise than using createElement and then setting attributes like cellSpacing and className via JS

Though this is a very old question  I thought it would be nice to update it with recent information   Since jQuery 1 8 there is a jQuery parseHTML   function which is now a preferred way of creating elements  Also  there are some issues with parsing HTML via     html code goes here     fo example official jQuery website mentions the following in one of their release notes      Relaxed HTML parsing  You can once again have leading spaces or   newlines before tags in   htmlString   We still strongly advise that   you use   parseHTML   when parsing HTML obtained from external   sources  and may be making further changes to HTML parsing in the   future    To relate to the actual question  provided example could be translated to   this  OuterDiv       parseHTML   lt div gt  lt  div gt          hide        append     parseHTML   lt table gt  lt  table gt              attr   cellSpacing   0             addClass  text             which is unfortunately less convenient than using just      but it gives you more control  for example you may choose to exclude script tags  it will leave inline scripts like onclick though     gt    parseHTML   lt div onclick  a  gt  lt  div gt  lt script gt  lt  script gt      lt div onclick   a  gt   lt  div gt      gt    parseHTML   lt div onclick  a  gt  lt  div gt  lt script gt  lt  script gt    document  true    lt div onclick   a  gt   lt  div gt     lt script gt   lt  script gt      Also  here s a benchmark from the top answer adjusted to the new reality   JSbin Link  jQuery 1 9 1       parseHTML     88ms       parseHTML   240ms    lt div  lt  div      138ms    lt div            143ms   createElement   64ms   It looks like parseHTML is much closer to createElement than      but all the boost is gone after wrapping the results in a new jQuery object

jQuery out of the box doesn t have the equivalent of a createElement   In fact the majority of jQuery s work is done internally using innerHTML over pure DOM manipulation   As Adam mentioned above this is how you can achieve similar results   There are also plugins available that make use of the DOM over innerHTML like appendDOM  DOMEC and FlyDOM just to name a few   Performance wise the native jquery is still the most performant  mainly becasue it uses innerHTML
