[英]How to make sure all ajax calls got executed successfully ( not completed)
[英]How to make sure my function executes after all ajax calls?
我有一个javascript函数。在此函数中,我有3个ajax调用。 这些ajax调用完成后,如何确保我的另一个函数执行?
function a(){
for(var i=0;i<3;i++)
$.post("somePage.php").done(function(){
do stuff here...
});
return false;
}
function b(){
//.....
}
我的函数b在ajax调用完成后会执行吗?
完整的解决方案将类似于
function a() {
var array = [], xhr;
for (var i = 0; i < 3; i++) {
xhr = $.post("somePage.php").done(function () {});
array.push(xhr)
}
//create a promise which will be called after all the ajax request are completed
return $.when.apply($, array);
}
function b() {
//.....
}
//on succss callback of all the ajax requests created in a call b
a().done(b)
编写一个增量检查,对每个返回的Ajax进行增量检查,如下所示:
increments = 0;
$.post("somePage.php").done(function(){
// Check if the increments are total to 3
++increments;
if(increments == 3) {
//do something now such as call b();
}
//do stuff here...
});
jQuery ajaxStop方法允许您注册所有Ajax请求完成后要调用的处理程序。
