使用jquery验证函数不适用于select元素

Question

I've got working validate function for my input fields :

$.tools.validator.fn("#password", function(input, value) {
    return value!='Password' ? true : {     
        en: "Please complete this mandatory field"
    };
});

$("#form").validator({ 
    position: 'bottom left', 
    messageClass:'form-error',
    message: '<div><em/></div>' // em element is the arrow
});

My input field :

<input type="password" id="password" class="full" value="" name="j_password" required="required" placeholder="Password" />

And tried the same logic for select but it's not working :

$.tools.validator.fn("#environment", function(select, value) {
    return value!='Select Environment' ? true : {     
        en: "Please choose the environment"
    };
});

My select (not working):

<select id="environment" style="opacity: 0; "><option value="Select Environment">Select Environment</option><option value="1">Dev</option><option value="2">Test</option></select>

My select (not working as well ):

<select id="environment" style="opacity: 0; "><option>Select Environment</option><option>Dev</option><option>Test</option></select>

Can someone point out where I'm making mistake and how to fix it ?

Update:

I'm using http://jquerytools.org/documentation/validator/index.html

Answer 1

I don't know if this is relevant but when I want to get the item selected from a dropdown I use $('#dropDownID option:selected').val() .

I would recommend displaying the value to see what you are actually getting, then try it this way.

Answer 2

Removed the style="opacity: 0;" and Your code seems to work fine, see: jsFiddle

Answer 3

如果你尝试使用$(select).val()来获取值，它应该从select中获得正确的选择值

With following code :

 $.tools.validator.fn("#environment", function(input, value) {          
         return value!='Select Environment' ? true : {     
                en: "Please select which environment you want to logon"
            };
        });
