jQuery 远程验证强制双击提交表单

Question

我正在尝试远程验证表单字段。如果当我在页面上时该字段获得焦点，那么一切都会很好。但是，如果该字段从未获得焦点，则该表单需要我单击“提交”按钮两次才能成功提交。

我希望它只验证字段是否获得焦点，或者以某种方式阻止表单需要单击两次才能提交。大家有什么想法吗？

$("#form1").validate({
    rules: {
        project: {
            required: true,
            remote: "check.php"
        }
    },
    messages: {
        project: {
            required: "Required.",
            remote: "Check Failed."
        }
    },
});

<input type="text" name="project" id="project" value="X"/>

Instead of making ajax setup to false you can just set "project" "remote" async to false like this

$("#form1").validate({
    rules: {
        project: {
            required: true,
            remote: {url:"check.php", async:false}
        }
    },
    messages: {
        project: {
            required: "Required.",
            remote: "Check Failed."
        }
    },
});
