Every time you create an ajax request you could use a variable to store it: var request = $.ajax({ type: ‘POST’, url: ‘someurl’, success: function(result){} }); Then you can abort the request: request.abort(); You could use an array keeping track of all pending ajax requests and abort them if necessary.
info = []; info[0] = ‘hi’; info[1] = ‘hello’; $.ajax({ type: “POST”, data: {info:info}, url: “index.php”, success: function(msg){ $(‘.answer’).html(msg); } });
This one did it for me: var input = $(“<input>”) .attr(“type”, “hidden”) .attr(“name”, “mydata”).val(“bla”); $(‘#form1′).append(input); is based on the Daff’s answer, but added the NAME attribute to let it show in the form collection and changed VALUE to VAL Also checked the ID of the FORM (form1 in my case) used the Firefox firebug to … Read more

$(“#selectId > option”).each(function() { alert(this.text + ‘ ‘ + this.value); }); http://api.jquery.com/each/ http://jsfiddle.net/Rx3AP/
This could help: $(‘#test’).find(‘option[text=”B”]’).val(); Demo fiddle This would give you the option with text B and not the ones which has text that contains B. For recent versions of jQuery the above does not work. As commented by Quandary below, this is what works for jQuery 1.9.1: $(‘#test option’).filter(function () { return $(this).html() == “B”; … Read more
This should get the id added. ASP.NET MVC 5 and lower: <% using (Html.BeginForm(null, null, FormMethod.Post, new { id = “signupform” })) { } %> ASP.NET Core: You can use tag helpers in forms to avoid the odd syntax for setting the id. <form asp-controller=”Account” asp-action=”Register” method=”post” id=”signupform” role=”form”></form>
As the error message states, jQuery does not include a :unchecked selector. Instead, you need to invert the :checked selector: $(“input:checkbox:not(:checked)”)
