问题一直是asked before，但是已经快四年了，也许有更好的解决方案。
我有一个$ .each循环，其中有时通过ajax获取其他数据。
我用获取的数据建立对象，循环后有一个从该对象生成HTML的函数。问题是循环在ajax数据到达之前完成。如果我在HTML生成功能中放置了警报，则内容正在正确加载。
我正在寻找一种仅在循环和所有ajax调用完成后才调用HTML-generator-function的解决方案。也许这是一种对启动的Ajax请求进行计数并等待所有请求完成的解决方案？
我相信jQuery延迟对我来说是正确的解决方案，但我只发现所有东西都停留在循环中的示例。有人可以帮忙吗？
我已将代码精简为最重要的内容：
//goes through each testplace -->main loop
$.each(jsobject, function(key, value)
{
//build object together...
for (var i = 0, numComputer = jenkinsComputer.contents.computer.length; i < numComputer; i++)
{
//If the testplace is in both objects then fire AJAX request
if (jenkinsComputer.contents.computer[i].displayName == key) //<<<This can happen only once per $.each loop, but it does not happen every time
{
//next $.each-iteration should only happen when received the JSON
var testplaceurl = jenkinsComputer.contents.computer[i].executors[0].currentExecutable.url;
$.when($.getJSON("php/ba-simple-proxy.php?url=" + encodeURI(testplaceurl) + "api/json?depth=1&pretty=1")).done(function(jenkinsUser)
{
//build object together...
});
}
}
}); //End of main Loop ($.each)
generateHTML(builtObject);
如果有人可以给我一些建议，那就太好了。
最佳答案
我会做这样的事情：
var thingstodo = $(jsobject).length;
var notfired = true;
$.each(jsobject, function(key, value)
{
//build object together...
for (var i = 0, numComputer = jenkinsComputer.contents.computer.length; i < numComputer; i++)
{
//If the testplace is in both objects then fire AJAX request
if (jenkinsComputer.contents.computer[i].displayName == key) //<<<This can happen only once per $.each loop, but it does not happen every time
{
//next $.each-iteration should only happen when received the JSON
var testplaceurl = jenkinsComputer.contents.computer[i].executors[0].currentExecutable.url;
$.when($.getJSON("php/ba-simple-proxy.php?url=" + encodeURI(testplaceurl) + "api/json?depth=1&pretty=1")).done(function(jenkinsUser)
{
//build object together...
thingstodo--;
if(thingstodo === 0 && notfired){
notfired = false;
generateHTML(buildObject);
}
});
}else{
thingstodo--;
}
}
}); //End of main Loop ($.each)
if(thingstodo === 0 && notfired){
generateHTML(buildObject);
}
