浏览器中输出指定unicode范围的汉字序列

话不多说，直接上脚本代码

一：获取汉字unicode 范围(获取数据源)

//获取数据源
//打开网站： https://www.qqxiuzi.cn/zh/hanzi-unicode-bianma.php
//控制台执行


{
    let arr=Array.from(document.querySelectorAll('tr'));
    arr.shift();
    result=[]
    arr.forEach((value,index,array)=>{
        let col1=value.firstElementChild.innerText
        let col2=value.firstElementChild.nextElementSibling.innerText
        let col3=value.firstElementChild.nextElementSibling.nextElementSibling.innerText
        console.log(col1,col2,col3)
        result.push([
            col1,col2,col3
        ])
    })
    console.log(JSON.stringify(result))
    let blob = new Blob([JSON.stringify(result)], {type: "application/json"});
    let url = window.URL.createObjectURL(blob);
    let a = document.createElement("a");
    a.style.display = "none";
    a.href = url;
    a.download = 'unicode-chinese.json';
    a.click();
    setTimeout(function () {
        window.URL.revokeObjectURL(url);
    }, 3000);

}
