javascript - jQuery:每个循环暂停直到完成

Question

我有以下 jQuery 循环，但在每个循环操作中我都有用户交互，代码应该等到用户交互完成。是否有可能暂停循环或是否有其他可能实现它？

jQuery.each([345, 897, 345 /* ... */], function(index, value) {
    // User interaction, need to wait the user finishing/answer

    // Here is a jQuery UI dialog with an input field in it
    // After the user entered their value and hit the submit button
    // which fires an own callback which could also continue the loop somehow?
});

Answer 1

您需要放弃 each 并自行处理。一种选择是这样的:

var curIndex = 0;
var ids = [345, 897, 345 /* ... */];

function doNext(){

  // check curIndex here to make sure you haven't completed the list, etc.

  var id = ids[curIndex++];

  // do stuff with this id
}

// THIS IS SOME SORT OF CODE EXECUTED WHEN THE "USER INTERACTION" FINISHES
function interactionDone(){
   doNext();
}
