随着salesforce lwc的优化,越来越多的项目从aura转到了lwc开发,没有lwc的知识是不能的,但是指望lwc可以搞定所有的场景是万万不能的,比如今天的场景,quick action。目前 quick action只允许选择 Aura Component,所以我们开发 quick action基本操作是 aura 套着 lwc实现功能。那如何更好的适配UI,本篇浅入浅出,做一些特定场景的demo,以便有需求的小伙伴可以快速参考上手。先来一个简单的demo。
quickActionLwcAdjustment.html
<template>
this is a component build by LWC
</template>
testQuickActionForLWC.cmp
<aura:component implements="force:lightningQuickActionWithoutHeader,force:hasRecordId,flexipage:availableForRecordHome,lightning:actionOverride">
<aura:attribute name="recordId" type="Id"/>
<c:quickActionLwcAdjustment/>
</aura:component>
将这个aura component配在 quick action中,我们demo中放在了account里面
展示效果:
嗯,实现了,目测没啥问题。但是总觉怪怪的,因为弹出的 Modal没有header,没有footer,但是大部分弹出的需要这些内容,所以,OK,我们继续往下探索,加一下header 以及 footer,demo中 header / footer放在lwc中。
1.0版改动尝试
quickActionLwcAdjustment.html
<template>
<div class="slds-modal slds-fade-in-open" style="width: 100%;">
<div class="slds-modal__container" style="width:100%;">
<header class="slds-modal__header">
<h2 class="title slds-text-heading--medium slds-hyphenate">header title section</h2>
</header>
<div class="slds-modal__content slds-p-around--medium">
<lightning-card style="text-align:center;">
<p class="title slds-text-heading--medium slds-hyphenate">this is a component build by LWC</p>
</lightning-card>
</div>
<div class="slds-modal__footer">
<lightning-button onclick={handleOKClick} variant="brand" label="OK" class="slds-m-right_x-small slds-no-flex text-right slds-float--right"></lightning-button>
</div>
</div>
</div>
</template>
quickActionLwcAdjustment.js
import { LightningElement } from 'lwc';
export default class QuickActionLwcAdjustment extends LightningElement {
handleOKClick(event) {
this.dispatchEvent(new CustomEvent('closemodal'));
}
}
testQuickActionFowLWC.cmp
<aura:component implements="force:lightningQuickActionWithoutHeader,force:hasRecordId,flexipage:availableForRecordHome,lightning:actionOverride">
<aura:attribute name="recordId" type="Id"/>
<c:quickActionLwcAdjustment onclosemodal="{!c.refreshAndCloseModal}"/>
</aura:component>
testQuickActionForLWCController.js
({
refreshAndCloseModal : function(component, event, helper) {
$A.get('e.force:refreshView').fire();
$A.get("e.force:closeQuickAction").fire();
}
})
效果展示:
尽管还有点丑,但是雏形出来了,做一下适配。
2.0版改动尝试
testQuickActionForLWC上面加一下的样式
<aura:html tag="style">
.slds-modal__content {
height:unset !important;
max-height:unset !important;
}
</aura:html>
尽管整体效果挺好,但是关闭的按钮却没有顶上去,所以没法作为最终版本,我们通过样式把关闭按钮隐藏,使用lwc展示
3.0版改动尝试
testQuickActionForLWC.cmp
<aura:component implements="force:lightningQuickActionWithoutHeader,force:hasRecordId,flexipage:availableForRecordHome,lightning:actionOverride">
<aura:html tag="style">
.slds-modal__close {
display: none;
}
.slds-modal__content {
height:unset !important;
max-height:unset !important;
}
</aura:html>
<aura:attribute name="recordId" type="Id"/>
<c:quickActionLwcAdjustment onclosemodal="{!c.refreshAndCloseModal}"/>
</aura:component>
quickActionLwcAdjustment.html
<template>
<div class="slds-modal slds-fade-in-open" style="width: 100%;">
<div class="slds-modal__container" style="width:100%;">
<header class="slds-modal__header inner">
<h2 class="title slds-text-heading--medium slds-hyphenate">header title section</h2>
<lightning-button-icon class="slds-button slds-button_icon slds-modal__close slds-button_icon-inverse"
icon-name="utility:close" alternative-text="close" title="close" onclick={handleOKClick}>
</lightning-button-icon>
</header>
<div class="slds-modal__content slds-p-around--medium">
<lightning-card style="text-align:center;">
<p class="title slds-text-heading--medium slds-hyphenate">this is a component build by LWC</p>
</lightning-card>
</div>
<div class="slds-modal__footer">
<lightning-button onclick={handleOKClick} variant="brand" label="OK" class="slds-m-right_x-small slds-no-flex text-right slds-float--right"></lightning-button>
</div>
</div>
</div>
</template>
quickActionLwcAdjustment.css:做一个派生选择器,先隐藏整体,然后指定css下子样式展示
.inner .slds-modal__close {
display: inline !important;
}
显示效果如下:
总结: 这个demo现在还有瑕疵,quick action展示的关闭按钮是白色,这个是透明色。本篇抛砖引玉,大神们类似需求如何实现,欢迎留言和讨论。篇中有错误欢迎指出,有不懂欢迎留言。
