How to change a button when clicked in Vue JS and Tailwind CSS-CodePudding

I'm trying to do a Dark mode button toggle, the fist step that I want to make is a icon that changes when I click in the button, but my code isn't running. That's my code:

<button href=""  @click="isDark = !isDark">
        <img src="../Assets/Icons/moon.svg" alt=""  v-if="isDark = true">
        <img src="../Assets/Icons/sun.svg" alt=""  v-if="isDark = false">
        </button>
<script>
export default {
  setup(){
    const showSidebar = ref(false)
    const stayInDropdown = ref(true)
    const isDark = ref(true)
    return{
      showSidebar,
      stayInDropdown,
      isDark,
    }
  },
</script>

CodePudding user response：

v-if="isDark = true" means assigning true to isDark not comparing them, the comparison should be like v-if="isDark === true" but you could just do v-if='isDark':

 <img v-if='isDark' src="../Assets/Icons/moon.svg" alt=""  >
 <img v-else src="../Assets/Icons/sun.svg" alt=""  >
