List Rendering 23 4.2 v-for In order to loop through each item in an array, we will use v-for Vue’s directive. The v-for loop works on arrays/objects and is used to loop through each item in an array. This directive requires a special syntax in the form of item in array where array is the source data Array and item is an alias for the Array element being iterated on. Warning If you are coming from the php world you may notice that v-for is similar to php’s foreach function. But be careful if you are used to foreach($array as $value). Vue’s v-for is exactly the opposite, value in array. The singular first, the plural next. 4.2.1 Range v-for Directive v-for can also take an integer. Whenever a number is passed instead of an array/object, the template will be repeated as many times as the number given. 1 2 3 5 Hello Vue 6 7 8 9 The multiplication table of 4. 10 11 12 {{ i }} times 4 equals {{ i * 4 }}. 13 14 15 16 17 18 19 new Vue({ 20 el: '.container' 21 })
List Rendering 24 22 23 The above code displays the multiplication table of 4. Note Multiplication Table of 4 Because we want to display all the multiplication table of 4 (until 40) we repeat the template 11 times since the first value i takes is 0.
