If you can use jquery then you can put the alert inside the   document  ready   function  it would look something like this    lt script gt      document  ready function        alert   lt    TempData  Resultat    gt            lt  script gt    To include jQuery  include the following in the  lt head gt  tag of your code    lt script type  text javascript  src  http   ajax googleapis com ajax libs jquery 1 jquery js  gt  lt  script gt    Here s a quick example in jsFiddle  http   jsfiddle net ChaseWest 3AaAx

There are three ways  The first is to put the script tag on the bottom of the page    lt body gt   lt  --Body content-- gt   lt script type  text javascript  gt  alert   lt    TempData  Resultat    gt      lt  script gt   lt  body gt    The second way is to create an onload event    lt head gt   lt script type  text javascript  gt  window onload   function     window addEventListener  load  function           for Netscape  and window attachEvent  onload  function           for IE and Opera  also work     alert   lt    TempData  Resultat    gt        lt  script gt   lt  head gt    It will execute a function when the window loads  Finally  the third way is to create a readystatechange event and check the current document readystate    lt head gt   lt script type  text javascript  gt  document onreadystatechange   function     window addEventListener  readystatechange  function           for Netscape  and window attachEvent  onreadystatechange  function           for IE and Opera  also work     if document readyState   loaded     document readyState   complete           alert   lt    TempData  Resultat    gt        lt  script gt   lt  head gt

Another option is to use the defer attribute on the script  but it s only appropriate for external scripts with a src attribute    lt script src    exampleJsFile js  defer gt   lt  script gt

Another option to resolve issue described in OP which I encountered on recent bootcamp training is using window setTimeout to wrap around the code which is bothersome  My understanding is that it delays the execution of the function for the specified time period  500ms in this case   allowing enough time for the page to load  So  for example    lt script type    text javascript  gt              window setTimeout function                    alert  Hello World                    500     lt  script gt

Why can t you use it in MVC   Rather than using the body load method use jQuery and wait for the the document onready function to complete

User · Answer

With the use of jQuery to handle the document ready event    lt script type  text javascript  gt   function onLoadAlert         alert   lt    TempData  Resultat    gt          document  ready onLoadAlert    lt  script gt    Or  even simpler - put the  lt script gt  at the end of body  not in the head
