我需要检查该表格是否为最后500毫米秒。 如果提交,则阻止提交。 就我的聊天而言,如果他/她的最后电文被发送到最后500毫米秒,我就需要停止发送电文的用户。 防止游泳的信号越多。 感谢!

尝试:
var start= (new Date()).getTime();
...................
var now = (new Date()).getTime();
var diff = now - start;//diff should be in milis
在您的提交书记中,储存了最后提交书的时间。 每当用户提交表格时,对照目前时间检查最后提交书的时间。
使用<代码>event.preventDefault()方法,在“......”后取消提交;500 ms。
$( yourForm ).on( submit , function (e) {
var self = $(this);
var lastSubmission = self.data( last ) || 0;
var now = (new Date()).getTime();
if (lastSubmission - now > 500) {
self.data( last , now);
} else {
e.preventDefault();
}
});
