jQuery - multiple document ready

Question

Question   If I link in two JavaScript files  both with   document  ready functions  what happens  Does one overwrite the other  Or do both   document  ready get called   For example    lt script type  text javascript  src  http   ajax googleapis com ajax libs jquery 1 4 1 jquery min js  gt  lt  script gt    lt script type  text javascript  src  http       jquery1 js  gt  lt  script gt    lt script type  text javascript  src  http       jquery2 js  gt  lt  script gt    jquery1 js      document  ready function            page-title   html  Document-ready was called           jquery2 js     document  ready function            page-subtitle   html  Document-ready was called            I m sure it is best practice to simply combine both calls into a single   document  ready but it s not quite possible in my situation

It is important to note that each jQuery   call must actually return   If an exception is thrown in one  subsequent  unrelated  calls will never be executed   This applies regardless of syntax   You can use jQuery    jQuery function          document  ready    whatever you like  the behavior is the same   If an early one fails  subsequent blocks will never be run   This was a problem for me when using 3rd-party libraries   One library was throwing an exception  and subsequent libraries never initialized anything

Execution is top-down  First come  first served   If execution sequence is important  combine them

document  ready    is the same as any other function  it fires once the document is ready - ie loaded  the question is about what happens when multiple   document  ready   s are fired not when you fire the same function within multiple   document  ready   s        this  lt div id  target  gt  lt  div gt     document  ready function       jQuery   target   append  target edit 1 lt br gt           document  ready function       jQuery   target   append  target edit 2 lt br gt           document  ready function       jQuery   target   append  target edit 3 lt br gt            is the same as  lt div id  target  gt  lt  div gt     document  ready function         jQuery   target   append  target edit 1 lt br gt          jQuery   target   append  target edit 2 lt br gt          jQuery   target   append  target edit 3 lt br gt            both will behave exactly the same  the only difference is that although the former will achieve the same results  the latter will run a fraction of a second faster and requires less typing      in conclusion where ever possible only use 1   document  ready       old answer  They will both get called in order  Best practice would be to combine them  but dont worry if its not possible  the page will not explode

Not to necro a thread  but under the latest version of jQuery the suggested syntax is      handler     Using an anonymous function  this would look like    function         insert code here           See this link   https   api jquery com ready

Both will get called  first come first served  Take a look here     document  ready function            page-title   html  Document-ready was called              document  ready function            page-title   html  Document-ready 2 was called             Output      Document-ready 2 was called

All will get executed and On first Called first run basis     lt div id  target  gt  lt  div gt    lt script gt      document  ready function        jQuery   target   append  target edit 1 lt br gt               document  ready function        jQuery   target   append  target edit 2 lt br gt               document  ready function        jQuery   target   append  target edit 3 lt br gt            lt  script gt    Demo As you can see they do not replace each other  Also one thing i would like to mention  in place of this    document  ready function         you can use this shortcut  jQuery function         dom ready codes
