透过禁用按钮避免jQuery.ajax重复请求

function disabledButton() {
	$("input[@type='submit']").each(function () {
	    $(this).bind("click", function () {
		   $(this).attr("disabled", true);
		   $(this).parents().filter("form").trigger("submit");
		});
	});
}


var initFun = window.onload;
if (initFun == null) {
	window.onload = disabledButton;
} else {
	window.onload = function () {
		initFun();
		disabledButton();
	};
}
