【问题描述】:
我正在尝试在 Salesforce 闪电网络组件中实现 handsonTable。 我了解这里的观众可能没有 Salesforce 知识,但希望共同努力找出问题所在。
以下是从示例中提取的一个非常基本的实现,但非常简化。
<head>
<link rel="stylesheet" type="text/css" href="https://cdn.jsdelivr.net/npm/handsontable@latest/dist/handsontable.full.min.css">
<link rel="stylesheet" type="text/css" href="https://handsontable.com/static/css/main.css">
<script src="https://cdn.jsdelivr.net/npm/handsontable@latest/dist/handsontable.full.min.js"></script>
</head>
<body>
<div id="hot"></div>
<script>
var dataObject = [{
id: 1,
currency: 'Euro'
}, {
id: 2,
currency: 'Japanese Yen'
}];
var hotElement = document.querySelector('#hot');
var hotElementContainer = hotElement.parentNode;
var hotSettings = {
data: dataObject,
columns: [{
data: 'id',
type: 'numeric',
width: 40
}, {
data: 'currency',
type: 'text'
}],
rowHeaders: true,
colHeaders: [
'ID',
'Currency'
]
};
var hot = new Handsontable(hotElement, hotSettings);
</script>
</body>
</html>
为了在 Salesforce Lightning Web Components (LWC) 中使用外部库,我使用https://developer.salesforce.com/docs/component-library/documentation/lwc/lwc.create_third_party_library 中提到的格式
将上面的 HTML 代码修改为提到的格式会给我 LWC JS 文件
import { LightningElement } from 'lwc';
import { ShowToastEvent } from 'lightning/platformShowToastEvent';
import { loadScript, loadStyle } from 'lightning/platformResourceLoader';
import handsonTableResource from '@salesforce/resourceUrl/handsonTable';
export default class handsonTable extends LightningElement {
dataObject = [
{
id: 1,
currency: 'Euro'
},
{
id: 2,
currency: 'Japanese Yen'
}
];
renderedCallback() {
Promise.all([
loadScript(this, handsonTableResource + '/handsontable.full.js'),
loadStyle(this, handsonTableResource + '/handsontable.full.css')
])
.then(() => {
this.initialiseHandsOnTable();
})
.catch(error => {
alert(error);
});
}
hotElement;
hotSettings;
initialiseHandsOnTable() {
this.hotElement = this.template.querySelector('div.hotElement');
this.hotSettings = {
data: this.dataObject,
columns: [
{
data: 'id',
type: 'numeric',
width: 40
},
{
data: 'currency',
type: 'text'
}
],
rowHeaders: true,
colHeaders: [
'ID',
'Currency'
]
};
new Handsontable(this.hotElement, this.hotSettings);
}
}
和 LWC html 一样
<template>
<div class="slds-m-around_medium">
<div class="hotElement" lwc:dom="manual"></div>
</div>
</template>
应用这些,在 Salesforce 中得到如下结果
(来源:handsontable.com)
生成的DOM如下
<c-handson-table data-data-rendering-service-uid="188" data-aura-rendered-by="322:0">
<div class="slds-m-around_medium">
<div class="hotElement handsontable htRowHeaders htColumnHeaders" id="ht_917e38abdce11495">

<div id="hot-display-license-info">The license key for Handsontable is missing. Use your purchased key to activate the product. Alternatively, you can activate Handsontable to use for non-commercial purposes by passing the key: 'non-commercial-and-evaluation'. <a target="_blank" href="https://handsontable.com/docs/tutorial-license-key.html">Read more</a> about it in the documentation or contact us at <a href="mailto:support@handsontable.com">support@handsontable.com</a>.</div>
</div>
</c-handson-table>
如您所见,正在为 handsonTable 生成 DOM 结构,但没有生成任何数据或列。 我在 Chrome 开发工具控制台上没有看到任何错误或警告(handson 表中的许可证警告除外)
我发现的一个观察结果是行数似乎反映了我们在屏幕上看到的内容。
a.countRows();
--> 2
a.countEmptyRows();
--> 0
a.countVisibleRows();
--> -1
a.countRenderedRows();
--> -1
我已经能够在面向公众的 URL 上发布实现。您可以通过https://sandbox-business-java-1763-16aaf9f33bb.cs6.force.com/ 访问我的实现 我在 initialiseHandsOnTable 函数的开头添加了一个调试器来提供帮助。
任何帮助将不胜感激。
