Question

For example, there is for loop that I want to sleep for some seconds.

$.each(para.res, function (index, item) {
    Sleep(100);
});

I know I can use setTimeout or setInterval but both of them are asychronous, the loop will continue, just the function in the setTimeout will run in a few seconds if I do it this way.

$.each(para.res, function (index, item) {
    setTimeOut(function(){do something},1000); 
});

Answer 1

You can define a function.

var i = 0;    
function recursive() {
  setTimeout(function(){
     var item = para.res[i];
     // do something
     i++;        
     if (i < para.res.length) recursive()
  }, 100)
}
