// 前端将数据导出josn文件；
saveJSON(data, filename) { if (!data) { alert('保存的数据为空'); return; } if (!filename) filename = 'json.json' if (typeof data === 'object') { data = JSON.stringify(data, undefined, 4) } var blob = new Blob([data], { type: 'text/json' }), e = document.createEvent('MouseEvents'), a = document.createElement('a') a.download = filename a.href = window.URL.createObjectURL(blob) a.dataset.downloadurl = ['text/json', a.download, a.href].join(':') e.initMouseEvent('click', true, false, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null) a.dispatchEvent(e) }
// 调用方式 obj（数据）;
saveJSON(obj,"obj.json")，就可以导出js的object变量了
