解决方法
TommyF的反应非常好.但是我建议将查看器用作动态Vue数据,这样您就可以在Vue组件中使用Viewer库方法,事件及其所有功能.
const app = new Vue({
el: '#app',data() {
return {
viewer: null,mode: 'modal',}
},created() {
},methods: {
zoom(value) {
this.viewer.zoom(value);
},close() {
this.viewer.exit();
},toggleMode(newmode) {
if (newmode != this.mode) {
this.mode = newmode;
this.viewer.destroy();
this.viewer = new Viewer(this.$refs.gallery,{
inline: (this.mode === 'inline'),url: 'data-original',});
}
}
},mounted() {
this.viewer = new Viewer(this.$refs.gallery,{
inline: false,});
}
})
见下面的例子：
const app = new Vue({
el: '#app',data() {
return {
viewer: null,}
},created() {
},methods: {
zoom(value) {
this.viewer.zoom(value);
},close() {
this.viewer.exit();
},toggleMode(newmode) {
if (newmode != this.mode) {
this.mode = newmode;
this.viewer.destroy();
this.viewer = new Viewer(this.$refs.gallery,{
inline: (this.mode === 'inline'),});
}
}
},mounted() {
this.viewer = new Viewer(this.$refs.gallery,{
inline: false,});
}
})
