<input type="submit" class="form-submit" value="Save" id="edit-submit" name="op">

the above is the submit button. i want to use jquery to do this. if the 1,2,3 input is no value. when he click the submit button. then alter a box. "you should write something."

this is my code. but it's too bad.

$(document).ready(function(){
if((#field-you-0-value).val()='' && .......)
$(#edit-submit).click(alert("test....."));

})
