jquery - Show all select box options that don't contain the value hello_ -

So I want to be able to hide all the options and then only show people who do not include hello_ their value includes Hello_by , Hello_Hello etc. Whoever starts with Hello _

is what I have done so far:

  jQuery ) .ready (function () {jQuery ("#metakeyselect" option). Hide (); jQuery ("#metakeyselect" gt; option [/]] What's here? / /] ")   
 How do I show everything, but how do I show values ​​along with Hello?   
 
 
 You can "hide" those people whose value is used by  Hello _ .  
 Tell that correctly Or you can not remove the option elements from all browsers (see also this). But you can remove them:  
  var hidden_options = jQuery ("#metakeyselect" option) [Value = = hello_] "). Remove ();   
 Or disable them:  
  jQuery ("#metakeyselect> option [value ^ = hello _]"). Prop ('disabled', true);   
 Depends on what you want to do with them.
