简单代码的jquery问题

Question

为什么这段代码不起作用

    var name = $("#name").val();    
    var email = $("#email").val();
    var web = $("#web").val();
    var comment = $("#comment").val();


    if(name.length < 5){
        $("#name").css("border-color","red");
    } elseif (email.length < 5) {
        $("#email").css("border-color","red");
    } elseif (web.length < 5) {
        $("#web").css("border-color","red");
    } elseif (comment.length < 10) {
        $("#comment").css("border-color","red");         
    }else{

alert('ok');

}

和每个像这样的val <input id="name" type="text" size="24" />

在javascript中你elseif需要else if,像这样:

if(name.length < 5) {
    $("#name").css("border-color","red");
} else if (email.length < 5) {
    $("#email").css("border-color","red");
} else if (web.length < 5) {
    $("#web").css("border-color","red");
} else if (comment.length < 10) {
    $("#comment").css("border-color","red");         
} else {
    alert('ok');
}
