1、最常见的window.open(url)可以满足就是get请求，参数在url中。
2、POST请求
第一种
前后端约定格式为字符串格式
$.ajax({ url:urls, type:"POST", data:args, responseType:'blob', success:
function(res){ download(res,$('#allExport_eventName').val()) } }); function
download(data,exportName){ if(!data){ return } var csv="\uFEFF"+data;
//为解决导出中文乱码问题 var url=window.URL.createObjectURL(new Blob([csv],{type:
'text/plain'})); var link=document.createElement('a') link.style.display='none'
link.href=url if(exportName){ link.setAttribute('download',exportName+'.csv') }
else{ link.setAttribute('download','事件.csv') } document.body.appendChild(link)
link.click() }
第二种
前后端约定格式为特定格式
let data={id:1,name:2} let formData=new FormData(); for(let k in data){
formData.append(k,data[k]); } const xhr = new XMLHttpRequest(); xhr.open('POST',
url, true); xhr.responseType = "blob"; xhr.onload = () => { var blob = new Blob
([xhr.response], {type: 'application/vnd.ms-excel'}); const blobUrl = URL.
createObjectURL(blob); var elink = document.createElement('a'); elink.style.
display= 'none'; elink.href = blobUrl; document.body.appendChild(elink); elink.
click(); document.body.removeChild(elink); } xhr.send(formData);
