有人可以帮助我实现这一目标吗? 我想在jquery中调用异步函数,并想停止一个过程,直到按我执行的顺序完成请求为止。使用jquery + ajax + python
$("upload_input").change( function(){
var opration = chcekFileonServer(filedata) // should complete first
uploadFileonServer(filedata,opration) // should complete second after finish first
print filename return by server // lastly
}
chcekFileonServer(filedata){
//use ajax call
if file exist
print confirm message to overwrite or copy //how to stop process here until I am not getting yes or no response from a user.
return file_name // return filename and userresponse(overwrite or copy)
}
uploadFileonServer(filedata){
//use ajax call
upload file to the server using ajax
return file_name
}
