🔬 Test in Browsers with Use js

1: copy pgk dir files to html dir
2: <input type="file" id="file" multiple="multiple" onchange="read()">

3:
<script>
    function read() {
        var file = document.getElementById('file').files[0]//获取文件流

        /// file: 前端File对象
        /// title_row: 标题在第几行 组合标题: [2,3]
        /// rows_excluded: 排除多少行数据, 一行, 二行, 三行: [1,2,3]
        /// excluded_keyword: 关键字排除: 在单元格中检测到该关键字读取终止
        read_excel_file(file, [5, 6, 7], [1, 2, 3, 4, 5, 6, 7, 8], "合计").then(res => {
            console.log("res", res);
        }).catch(e => {
            alert(e);
        });
    }
</script>

4:
<script type="module">
    // 初始化wasm里的方法
    import {default as wasm, greet, read_excel_file} from "./excel_read.js";
    wasm().then((module) => {
        window.read_excel_file = read_excel_file;
    });
</script>

🔋 Batteries Included

• wasm-bindgen for communicating between WebAssembly and JavaScript.
• console_error_panic_hook for logging panic messages to the developer console.
• wee_alloc, an allocator optimized for small code size.
