[英]Nesting Ajax calls in Prototype
I need to make two Ajax calls, one dependent on the return value of the previous call.我需要进行两个 Ajax 调用,一个取决于前一个调用的返回值。 I've attempted to create a new Ajax object from within the onComplete function of the outer object, however it seems that this never gets called.
我试图从外部 ZA8CFDE63311BD59EB266ZB6F 的 onComplete function 中创建一个新的 Ajax object
The onComplete function of the outer object is being called.正在调用外部 object 的 onComplete function。 Code is executed up to where I construct the second Ajax object.
代码执行到我构造第二个 Ajax object 的位置。
It looks something like this:它看起来像这样:
function called_from_page() {
new Ajax.Request(
'/request_url',
{ method: 'post', parameters: '', onComplete: function(originalRequest) {
if (originalRequest.responseText == '0') {
// do something
} else {
call_next_ajax();
}
}});
}
function call_next_ajax() {
new Ajax.Request(
'/next_request_url',
{ method: 'post', parameters: '', onComplete: some_other_function });
}
So, the problem is, that call_next_ajax is being called, but the ajax request within it is not being called.所以,问题是,call_next_ajax 被调用了,但是其中的 ajax 请求没有被调用。
The only problem I can think of is: there is no 'next_request_url' or there is no 'some_other_function'.我能想到的唯一问题是:没有'next_request_url'或没有'some_other_function'。 In both cases 'call_next_ajax()' will not execute.
在这两种情况下,'call_next_ajax()' 都不会执行。
