Info

A Flavor of Directives. 13 Info An element with v-show will always be rendered and remain in the DOM. v-show simply toggles the display CSS property of the element. 1 You must send a message for help! 2 3 4 Send word to allies for help! 5 What we want to accomplish in this example, is to toggle different elements. In this step, we need to hide the warning inside the h1 tag, if a message is present, otherwise hide the message by setting its style to **display: none. 3.2 v-if In this point you might ask ‘What about the v-if directive we mentioned earlier?’, so we will build the previous example again, only this time we’ll use v-if! 1 2 3 Hello Vue 4 5 6 7 You must send a message for help! 8 9 10 Send word to allies for help! 11 12 13 {{$data | json}} 14 15 16 17 18 19 new Vue({ 20 el: '#app',
A Flavor of Directives. 14 21 data: { 22 message: 'Our king is dead! Send help!' 23 } 24 }) 25 26 As shown, the replacement of v-show with v-if works just as good as we thought. Go ahead and try to make your own experiments to see how this works! The only difference is that an element with v-if will not remain in the DOM. 3.2.1 Template v-if If sometime we find ourselves in a position where we want to toggle the existence of multiple elements at once then we can use v-if on a element. In occasions where the use of div or span seems appropriate, the element can serve also as an invisible wrapper. Also the won ‘t be rendered in the final result. 1 2 3 You must send a message for help! 4 Dispatch a messenger immediately! 5 To nearby kingdom of Hearts! 6 7 8 9 Send word to allies for help! 10 11 12 {{$data | json}} 13 14
