function getBoundary() {
let list = [];
for (let item of list) {
let location = util.bd_decrypt(Number(item[0]), Number(item[1]))
list.push([location.bd_lat, location.bd_lng])
}
var content = JSON.stringify(list);
var eleLink = document.createElement(‘a’);
eleLink.download = “list.json”;
eleLink.style.display = ‘none’;
// 字符内容转变成blob地址
var blob = new Blob([content]);
eleLink.href = URL.createObjectURL(blob);
// 触发点击
document.body.appendChild(eleLink);
eleLink.click();
// 然后移除
document.body.removeChild(eleLink);
