我必须在一个servlet中添加4个函数，如添加，删除，更新，搜索。我正在使用jquery来验证我的表单。那么，我怎样才能在jquery中放置单独的按钮动作。我在下面添加了验证脚本。任何人都可以帮我做这个......
$(document).ready(function() {
$("#departmentId").keypress(function (e)
{
//if the letter is not digit then display error and don't type anything
if( e.which!=8 && e.which!=0 && (e.which<48 || e.which>57))
{
//display error message
$("#errmsg").html("Digits Only").show().fadeOut("slow");
return false;
}
});
$('.btn-delete').click(function(e){
// Declare the function variables:
// Parent form, form URL, email regex and the error HTML
var $formId = $(this).parents('form');
var formAction = $formId.attr('action');
var $error = $('<span class="error"></span>');
// Prepare the form for validation - remove previous errors
$('li',$formId).removeClass('error');
$('span.error').remove();
// Validate all inputs with the class "required"
$('.required',$formId).each(function(){
var inputVal = $("#departmentId").val();
var $parentTag = $("#departmentId").parent();
if(inputVal == ''){
$parentTag.addClass('error').append($error.clone().text('Required Field'));
}
// Run the email validation using the regex for those input items also having class "email"
// Check passwords match for inputs with class "password"
});
// All validation complete - Check if any errors exist
// If has errors
if ($('span.error').length > 0) {
$('span.error').each(function(){
// Set the distance for the error animation
var distance = 5;
// Get the error dimensions
var width = $(this).outerWidth();
// Calculate starting position
var start = width + distance;
// Set the initial CSS
$(this).show().css({
display: 'block',
opacity: 0,
right: -start+'px'
})
// Animate the error message
.animate({
right: -width+'px',
opacity: 1
}, 'slow');
});
} else {
$formId.submit();
}
// Prevent form submission
e.preventDefault();
});
// Fade out error message when input field gains focus
$('.required').focus(function(){
var $parent = $(this).parent();
$parent.removeClass('error');
$('span.error',$parent).fadeOut();
});
