问题描述
我的问题很简单-
我正在使用jquery和ajax提交表单.单击该按钮后,数据将提交到数据库.
I am submitting form using jquery and ajax . When the button is clicked the data is submitted to database .
问题-如果用户单击两次提交,则数据库中有两个条目.我该如何解决?
Question - If the user clicks the submit twice there are two entries in the database . how can I solve this ?
我不能使用.one(),因为如果发生错误,则提交按钮将调用验证功能,因此不会提交数据.因此,用户必须再次调用同一功能.
I cannot use .one() because the submit button invokes validation function if the errors happen the data will not be submitted .So , user has to call the same function again .
很明显,我可以使用.success上的变量来执行此操作,但是解决此问题的最佳方法是什么.
Obviously I can do that with a variable on .success .but what is the best solution to this issue .
感谢您的帮助.
推荐答案
覆盖以防止点击是一种方法.
Overlaying to prevent click is one way.
如果您想要一些即插即用的blockUI.js很好.您只需要
If you want something plug and play blockUI.js is good. All you need is
$(document).ajaxStart($.blockUI).ajaxStop($.unblockUI);
,或者您可以只使用.ajaxstart()
和.ajaxstop(
)自己覆盖元素以启用和禁用提交按钮.
or you can just use .ajaxstart()
and .ajaxstop(
) to overlay an element yourself to enable and disable the submit button.
