javascript click a button with if statement to compare text variable

can you please help me with this :

I am trying to click three different buttons with different ids, but based on a string variable name in javascript like :

function my_custom_js_func(){

  jQuery( "#listViewer" ).click();

};

but this will always click the button with id listViewer

i have a variable :

 var viewTog = "List";

or : var viewTog = "Grid";

I want to do something like this :

 function my_custom_js_func(){

  if (viewTog == "List") {jQuery( "#listViewer" ).click();};
  if (viewTog == "Grid") {jQuery( "#gridViewer" ).click();};

};

but it doesn't work, I am using the variable viewTog as a memory.

thank you !
