带有ajax内容的滑块 [英] Slider with ajax content

问题描述

我有一个jquery滑块，默认情况下它是关闭的.因此，当用户尝试打开并发送ajax请求时，数据就来了.我的问题是每次用户关闭并打开ajax请求时都会发送.那么我如何才能第一次进行Ajax调用，如果用户关闭并打开滑块则如何保留数据?

My problem is each time the user closes and opens the ajax request is send. so how can i make the ajax call for the first time and if the user closes and opens the slider how to retain the data?

推荐答案

您可以设置变量，例如:

You can set a variable, for example:

var alreadySent = false;

然后在您的ajax回调函数中将其更改为true(假设您使用的是jQuery post):

then in your ajax callback function you can change it to true (assuming you are using jQuery post):

if (!alreadySent) {
  $.post("address", params, function(data) {
    // do something
    alreadySent = true;
  });
}
