javascript - Why window.setTimeout throws an exception in IE9? -

here's code:

save: function(){ window.settimeout(recipecontrolsviewmodel.savewotimeout(),500); },

here's error in ie9 when "display notification every script error" alternative checked in net options in ie9. doesn't happen in firefox, chrome or ie10 & ie11.

script87: invalid argument

does know why happens , how prepare this?

you need wrap function phone call in anonymous function:

save: function(){ window.settimeout(function() { recipecontrolsviewmodel.savewotimeout() },500); },

alternatively, ie9 forwards can utilize .bind():

save: function(){ window.settimeout(recipecontrolsviewmodel.savewotimeout.bind(recipecontrolsviewmodel) },500); },

though in case that's more typing. .bind() function returns function that's "bound" object pass it. means returned function phone call original function (the 1 referred "savewotimeout" property) argument ("recipecontrolsviewmodel") value of this.
