Answer 1

类似的东西：

$("form").submit(function(event) {
    var email1Validation = function() {
        if($("input:text[name='attendant\\[\email\]']", this).filter(function() {
            return $.trim(this.value) == "";
        }).length) {
            window.alert("No member email1 should be empty.");
            return true;
        }
    },
    email2Validation = function() {
        if ($("input:text[name='attendant\\[\email2\]']", this).filter(function() {
            return $.trim(this.value) == "";
        }).length) {
            window.alert("No member email2 should be empty.");
            return true;
        }
    }
    if(email1Validation() || email2Validation()) {
        event.preventDefault();
    }
});

$("form").submit(function(event) {
    if ($("input:text[name='attendant\\[\email\]']", this).filter(function() {
            return $.trim(this.value) == "";
        }).length) {
        window.alert("No member email1 should be empty.");

        event.preventDefault();
    }
       else if ($("input:text[name='attendant\\[\email2\]']", this).filter(function() {
            return $.trim(this.value) == "";
        }).length) {
        window.alert("No member email2 should be empty.");

        event.preventDefault();
    }
});

这是你需要做的...... 希望它可以帮到你。
