我们使用以下jQuery来禁用提交按钮以防止双重提交(服务器速度慢!)。
jQuery(document).ready(function($){
/*SENDE BTN INAKTIV STELLEN*/
$("input[type=submit]").click(function() {
$(this).css({'opacity':'0.5','cursor':'wait'}).attr('disabled','disabled');
});
});
但是,在浏览器验证HTML表单中具有“required”属性的所有字段后,我们如何触发脚本?

EDIT: I found a much more elegant way to do this. Please accept this answer if it works for you.
jQuery(document).ready(function($){
/*SENDE BTN INAKTIV STELLEN*/
$("input[type=submit]").click(function() {
var myform = $('#theform');
//checks if the form is valid
if(myform[0].checkValidity())
{
$(this).css({'opacity':'0.5','cursor':'wait'}).attr('disabled','disabled');
}
});
});
//this is slightly awkward but it works
jQuery(document).ready(function($){
/*SENDE BTN INAKTIV STELLEN*/
$("input[type=submit]").click(function() {
var flag = true;
$('[required]').each(function(){
if(!$(this).val())
flag = false;
});
if(flag){
$(this).css({'opacity':'0.5','cursor':'wait'}).attr('disabled','disabled');
}
else
return false;
});
});
