Navigating through Dropdown Menus

I'm working on implementing a drop-down menu in my HTML, and my goal is to have a JavaScript function called whenever the user changes the selected value in the menu. Currently, here's what I have:

HTML/PHP:

<select name="selectSquad" class="SquadWeaponSelector" id="selectSquad" onchange="javascript:showWeaponEditorWindow(this.form.selectSquad);">
<?PHP
   $max = $squadNumbers - 1;
   $i = 0;
   while($i <= $max){
      echo "<option value=\"".$names_split[$i]."\"/>".$names_split[$i]."</option>";
      $i++;
   }
?>
</select>

JavaScript – desired behavior:

function showWeaponEditorWindow(squad){
   if(squad == "A PHP Value - Jack"){
      alert("jack selected");
   }
}

Any suggestions on how I can achieve this functionality?

Answer №1

Give this a shot, make sure you set squad.value within your condition.

<select name="selectSquad" class="SquadWeaponSelector" id="selectSquad" onchange="showWeaponEditorWindow(this);">


function showWeaponEditorWindow(squad){
   if(squad.value == "A PHP Value - Jack"){
     alert("jack selected");
  }
}

Update:

you can utilize selectedIndex to retrieve the selected menu item, remembering that the menu index starts at 0;

therefore, modify squad.value to 

(squad.selectedIndex == 1)

Answer №2

If you're looking for a solution, I suggest utilizing jQuery in this scenario. You can simply implement the following code:

$('#selectSquad').change(function(){
   var selectedValue = $(this).val();
   // Utilize the selectedValue variable as needed
});
