下载文件

下载/导出文件

1.不带参数

window.open(url);

2.带参数

window.open(".../?para1="+para1val+"&para2="+para2val);

前端处理下载数据

H5 chrome支持；IE 11;IE edge 不支持

 download(filename, text) {
        var element = document.createElement('a')
        element.setAttribute('href', 'data:text/plain;charset=utf-8,' + encodeURIComponent(text))
        element.setAttribute('download', filename)
      
        element.style.display = 'none'
        document.body.appendChild(element)
      
        element.click()
      
        document.body.removeChild(element)
}

使用blob 下载

download(filename, text) {
    var aLink = document.createElement('a')
    var blob = new Blob([text], {
      type: 'text/plain'
    })
    aLink.download = filename
    aLink.href = URL.createObjectURL(blob)
    if(!!window.ActiveXObject || 'ActiveXObject' in window){ //兼容IE
      window.navigator.msSaveOrOpenBlob(blob, filename)
    }else {
      aLink.click()
    }
    URL.revokeObjectURL(blob)
    aLink = null
    blob = null
 },
