The idea is simple, if all the JQuery executions are completed, then it will return jQuery.active == 0 which we can use in our Wait.Until method to wait till the script return as true. Wait for Ajax call to fin
1.对所有请求使用Fetch或Axios。混合它们只会导致更大的爆炸半径和更困难的测试

wait after each page interaction. Whether you click or hover over a web element, execute a javascript function, or simulate a keypress, it can cause either a page transition or an ajax operation. You would need to wait for this to complete before you can perform the next operation. If ...
then(function () { return ThirdAsync(); }) .done(function () { finish(); }); 同时,要记住的是,如果你没有在done()中添加错误处理程序,而且操作出现错误,它会抛出异常,这将消耗整个事件循环。即使写在try catch块中,你也无法捕获这样的异常,而唯一能获取它的方式是通过window.onerror()。
jQuery.ajax({ url: 'https://api.example.com/endpoint', success: function(response) { ...
这里使用Ajax请求作为示例,你可以让任何代码块异步执行。 这可以通过 setTimeout(callback,milliseconds) 函数来完成。setTimeout 函数的作用是设置一个回调函数milliseconds后执行,如下: function first() { console.log('first'); } function second() { console.log('second'); } function third() { console....
AJAX stands for: Asynchronous – means that if you start some request (call some API), you can move on to another task before that request is finished. This is the direct opposite of when you execute something synchronously – in that case, you have to wait for it to finish before movin...
