$("#tournamentDesignTabs").tabs();
$("#tournamentDesign").validate();
$("#createTournament").click(function(){
if($("#tournamentDesign").validate()){
$.post(
"createTournament.php",
{tournamentName: $("#tournamentName").val(), district: $("#district").val(), region: $("#region").val(), location: $("#location").val(), date: $("#date").val(), time: $("#time").val(), logo: $("#logo").val()},
function(responseText){
$("#result").html(responseText);

"html" )
} else {
alert("oh no");
}
}
);
以上是我用来验证某些表单信息然后将其输入数据库的脚本。我遇到的问题是，当附加到span的click事件处理程序时，validate函数似乎没有做任何事情。我也注意到onfocusout似乎也表现不正常。关于我做错了什么的任何建议或想法。我知道我已正确包含插件，因为验证功能在我提交表单时仍然有效。我更喜欢ajax。谢谢！
编辑：正如下面的一个答案所说，他们认为拥有html会有所帮助，所以这里是页面。最后一点代码和内容。我知道它很脏而且很乱，但我正在学习并很快就会清理它。无论如何它是：<!DOCTYPE HTML SYSTEM>

答案 0 :(得分：2)
.validate()初始化了form上的验证插件。
.valid()会返回true或false，具体取决于您的表单目前是否有效。
因此，您要在.valid()语句中使用.validate()而不是if来测试表单是否有效...
$("#tournamentDesign").validate();
$("#createTournament").click(function(){
if($("#tournamentDesign").valid()){
...
