@confirmClick="confirmClick"></cc-codeDialog>
</view>
</template>
<script>
export default {
data() {
return {
show: false
}
},
methods: {
showCodeDialog(item) {
this.show = true;
},
closeCodeDialog(item) {
this.show = false;
},
confirmClick(result) {
console.log("result = " + JSON.stringify(result));
this.show = false;
}
}
}
</script>
<style>
.content {
display: flex;
flex-direction: column;
background-color: aliceblue;
