VueJs Conditional Rendering


Syntax


//v-if
//v-if | v-else
//templated v-if
//v-show


Remarks


It is very important to remember the difference between v-if and v-show. While their uses are almost identical, an element bound to v-if will only render into the DOM when it's condition is true for the first time. When using the v-show directive, all elements are rendered into the DOM but are hidden using the display style if the condition is false!

Examples



Overview


In Vue.js, conditional rendering is achieved by using a set of directives on elements in the template.

v-if


Element displays normally when condition is true. When the condition is false, only partial compilation occurs and the element isn't rendered into the DOM until the condition becomes true.

v-else


Does not accept a condition, but rather renders the element if the previous element's v-if condition is false. Can only be used after an element with the v-if directive.

v-show


Behaves similarly to v-if, however, the element will always be rendered into the DOM, even when the condition is false. If the condition is false, this directive will simply set the element's display style to none.
