我在使用jquery .each()和.ajax()函数时遇到了问题.我正在使用.each()循环遍历5个元素,并为每个元素执行.ajax()调用.我的问题是,我只希望在从每个ajax请求收到响应时继续循环.目前,所有5个元素都在循环,5个ajax请求正在进行,然后返回5个响应.
她是一个简单的例子:
$(".element").each(function() { var id= $(this).find(('txtId').val(); $.ajax({ type: "POST",url: "/Handlers/Handler.ashx",data: "ID=" + id,success: function(xml){ // I would like the each() loop to pause until this is hit,// and some additional logic can be performed. } }); });
干杯.
解决方法
您可以使用
async
选项使每个请求同步(=在每个请求完成之前暂停脚本执行):
async
By default,all requests are sent asynchronous (i.e. this is set to true by default). If you need synchronous requests,set this option to false. Cross-domain requests and dataType: “jsonp” requests do not support synchronous operation. Note that synchronous requests may temporarily lock the browser,disabling any actions while the request is active.
但是,正如文档已经说过的那样,这是非常气馁的,因为如果请求挂起或超时,它可能会冻结浏览器.
