我目前正在通过CSS在动态sap.m.table中静态设置背景图像。但是,我想用Javascript而不是CSS设置背景图像。例如,给定这样的图像数组:
var imgArray = imageUrl1, imageUrl2, imageUrl3, imageUrl4.
我想遍历数组并将表的单元格分配给imageUrls。
我目前正在CSS中执行以下操作:
.sapMListTblCell:nth-child(2) {
background-image: url("https://image.shutterstock.com/image-photo/cute-baby-tabby-short-hair-260nw-160585535.jpg");
background-size: contain;
background-repeat: no-repeat;
background-position: center;
}
这里是jsbin的链接,描述了我如何创建表:https://jsbin.com/huyiyofexu/edit?html,css,js,output。

有多种方法可以执行此操作,但是我建议从表中创建2d数组,然后根据行和列数执行您喜欢的任何逻辑对其进行迭代:
const bgs = [
["red", "green", "blue"],
["magenta", "yellow", "cyan"],
["black", "gray", "white"]
];
document.addEventListener("DOMContentLoaded", () => {
const myTable = document.getElementById("MyTable");
const trs = Array.from(myTable.querySelectorAll("tr"));
const grid = trs.map((tr) => {
const tds = Array.from(tr.querySelectorAll("td"));
return tds;
});
grid.forEach((row, rowNum) => {
row.forEach((tdElement, colNum) => {
tdElement.style.background = bgs[rowNum][colNum];
});
});
});
td {
height: 100px;
width: 100px;
text-align: center;
}
<table id="MyTable">
<tr>
<td>1-1</td>
<td>1-2</td>
<td>1-3</td>
</tr>
<tr>
<td>2-1</td>
<td>2-2</td>
<td>2-3</td>
</tr>
<tr>
<td>3-1</td>
<td>3-2</td>
<td>3-3</td>
</tr>
</table>
