(像上面這種加了style并不會實現(xiàn)漸變效果,因為vue默認是會盡量復(fù)用dom,想要vue不復(fù)用dom,要給其加上不同的key值)
專注于為中小企業(yè)提供成都網(wǎng)站建設(shè)、網(wǎng)站建設(shè)服務(wù),電腦端+手機端+微信端的三站合一,更高效的管理,為中小企業(yè)尼金平免費做網(wǎng)站提供優(yōu)質(zhì)的服務(wù)。我們立足成都,凝聚了一批互聯(lián)網(wǎng)行業(yè)人才,有力地推動了上1000+企業(yè)的穩(wěn)健成長,幫助中小企業(yè)通過網(wǎng)站建設(shè)實現(xiàn)規(guī)模擴充和轉(zhuǎn)變。
加上不同key值后,漸變效果有了:
<!DOCTYPE?html> <html> <head> ????<title></title> ????<meta?http-equiv="Content-Type"?content="text/html;?charset=utf-8"?/> ????<link?rel="stylesheet"?type="text/css"?href="./animate.css"> ????<script?src="./vue.js"></script> ????<!--?<script?src="http://cdn.staticfile.org/vue/2.6.10/vue.common.dev.js"></script>?--> ????<style> ????????.myfade-enter,?.myfade-leave-to?{ ????????????opacity:?0; ????????} ????????.myfade-enter-active,?.myfade-leave-active?{ ????????????transition:?opacity?1s; ????????} ????</style> </head> <body> ????<div?id="root"> ????????<transition?name="myfade"> ????????????<div?v-if="show"?key="hello">hello</div> ????????????<div?v-else?key="bye">bye</div> ????????</transition> ????????<button?@click="handleClick">切換</button> ????</div> ????<script?type="text/javascript"> ????????var?vm?=?new?Vue({ ????????????el:?"#root", ????????????data:?{ ????????????????show:?true ????????????}, ????????????methods:?{ ????????????????handleClick:?function()?{ ????????????????????this.show?=?!this.show ????????????????} ????????????} ????????}); ????</script> </body> </html>
如果想設(shè)置多個屬性之間的切換效果,可以用mode(mode="in-out":先顯示要顯示的再隱藏要隱藏的。mode="out-in":和前面的相反):
<!DOCTYPE?html> <html> <head> ????<title></title> ????<meta?http-equiv="Content-Type"?content="text/html;?charset=utf-8"?/> ????<link?rel="stylesheet"?type="text/css"?href="./animate.css"> ????<script?src="./vue.js"></script> ????<!--?<script?src="http://cdn.staticfile.org/vue/2.6.10/vue.common.dev.js"></script>?--> ????<style> ????????.myfade-enter,?.myfade-leave-to?{ ????????????opacity:?0; ????????} ????????.myfade-enter-active,?.myfade-leave-active?{ ????????????transition:?opacity?1s; ????????} ????</style> </head> <body> ????<div?id="root"> ????????<transition?name="myfade"?mode="out-in"> ????????????<div?v-if="show"?key="hello">hello</div> ????????????<div?v-else?key="bye">bye</div> ????????</transition> ????????<button?@click="handleClick">切換</button> ????</div> ????<script?type="text/javascript"> ????????var?vm?=?new?Vue({ ????????????el:?"#root", ????????????data:?{ ????????????????show:?true ????????????}, ????????????methods:?{ ????????????????handleClick:?function()?{ ????????????????????this.show?=?!this.show ????????????????} ????????????} ????????}); ????</script> </body> </html>
組件動畫也是可以的(不需要上面的不同值的key):
<!DOCTYPE?html> <html> <head> ????<title></title> ????<meta?http-equiv="Content-Type"?content="text/html;?charset=utf-8"?/> ????<link?rel="stylesheet"?type="text/css"?href="./animate.css"> ????<script?src="./vue.js"></script> ????<!--?<script?src="http://cdn.staticfile.org/vue/2.6.10/vue.common.dev.js"></script>?--> ????<style> ????????.myfade-enter,?.myfade-leave-to?{ ????????????opacity:?0; ????????} ????????.myfade-enter-active,?.myfade-leave-active?{ ????????????transition:?opacity?1s; ????????} ????</style> </head> <body> ????<div?id="root"> ????????<transition?name="myfade"?mode="out-in"> ????????????<child1?v-if="show">hello</child1> ????????????<child2?v-else>bye</child2> ????????</transition> ????????<button?@click="handleClick">切換</button> ????</div> ????<script?type="text/javascript"> ????????Vue.component("child1",?{ ????????????template:?"<div>child1</div>" ????????}); ????????Vue.component("child2",?{ ????????????template:?"<div>child2</div>" ????????}); ????????var?vm?=?new?Vue({ ????????????el:?"#root", ????????????data:?{ ????????????????show:?true ????????????}, ????????????methods:?{ ????????????????handleClick:?function()?{ ????????????????????this.show?=?!this.show ????????????????} ????????????} ????????}); ????</script> </body> </html>
動態(tài)組件的實現(xiàn)方法:
<!DOCTYPE?html> <html> <head> ????<title></title> ????<meta?http-equiv="Content-Type"?content="text/html;?charset=utf-8"?/> ????<link?rel="stylesheet"?type="text/css"?href="./animate.css"> ????<script?src="./vue.js"></script> ????<!--?<script?src="http://cdn.staticfile.org/vue/2.6.10/vue.common.dev.js"></script>?--> ????<style> ????????.myfade-enter,?.myfade-leave-to?{ ????????????opacity:?0; ????????} ????????.myfade-enter-active,?.myfade-leave-active?{ ????????????transition:?opacity?1s; ????????} ????</style> </head> <body> ????<div?id="root"> ????????<transition?name="myfade"?mode="out-in"> ????????????//通過動態(tài)組件的方式實現(xiàn): ????????????<component?:is="type"></component> ????????</transition> ????????<button?@click="handleClick">切換</button> ????</div> ????<script?type="text/javascript"> ????????Vue.component("child1",?{ ????????????template:?"<div>child1</div>" ????????}); ????????Vue.component("child2",?{ ????????????template:?"<div>child2</div>" ????????}); ????????var?vm?=?new?Vue({ ????????????el:?"#root", ????????????data:?{ ????????????????type:?"child1" ????????????}, ????????????methods:?{ ????????????????handleClick:?function()?{ ????????????????????this.type?=?this.type?==?"child1"???"child2"?:?"child1" ????????????????} ????????????} ????????}); ????</script> </body> </html>
