问题描述

我有问题。

for(a=1;a<10;a++){
    $(".div").append("<div id="+a+"></div>")
        $.ajax({
              url: "file.php",
              data: "a="+a,
              type: "POST",
              async: false,
              success: function(data) {
                $("#"+a).html(data);
              }
        });

}
 $("div").click(function(){
        alert("it works");
 });

问题是: 是我没有把有异步:从假数据的为file.php 的仅在过去的div所以用ID 9 但现在有异步:假 - 这样的数据在每一个div中,这样的好

problem is: is I didn't put there async: false data from file.php are only in last div so with id 9 but now there is async: false - so data are in every div so that is good

但是,如果我想点击,而它加载阿贾克斯不工作(仅限于完成后,所有的Ajax-ES)

but if i want click while it was loading by ajax it doesn't work (only after finished all ajax-es)

如何解决这个问题呢? (也许我使用AJAX的错误是,我可以使用的getJSON等..)

how resolve this problem? (maybe the false is that am I using ajax. I can use getJSON ect..)

推荐答案

如果您希望用户能够使用该接口Ajax调用运行时,你应该改变你的异步。也有人指出,由詹姆斯·阿勒代斯,在这种情况下,你需要使用JavaScript闭包来保留原始 ID 的值时,返回Ajax调用。有关JavaScript的闭包的更多信息,请查看<一个href="http://stackoverflow.com/questions/111102/how-do-javascript-closures-work">how-do-javascript-closures-work,发现这里的计算器一个非常好的问题。

If you want the user to be able to use the interface while the ajax call is running, you should change your async to true. It has also been noted by James Allardice that in this scenario you need to use a javascript closure to retain the value of your original id for when the ajax call is returned. For more information regarding javascript closures check out how-do-javascript-closures-work, a really good question found here on stackoverflow.

for(id = 1; id < 10; id++){
    $(".div").append("<div id='" + id + "'></div>");

    (function(id) {
        $.ajax({
            url: "file.php",
            data: "a=" + id,
            type: "POST",
            async: true,
            success: function(data) {
                $("#"+ id).html(data);
            }
        });
     }(id));
}
