这里我只想在一个页面中使用两个提交按钮，但它不通过post发送任何数据？
<form name="form_post" id="form-post" method="post">
<label>
<span>Title *</span>
<input type="text" name="post_name" id="post-name" placeholder="Post title...." required>
</label>
<label>
<span>Body *</span>
<input type="text" name="post_body" id="post-body" placeholder="Post body...." required>
</label>
<input type="submit" id="submit_post" value="Submit Post">
</form>
这是另一种形式：
<form id="form_comment" method="post">
<!-- need to supply post id with hidden fild -->
<input type="hidden" name="postid" value="<?php echo $post_id ?>">
<label>
<span>Name *</span>
<input type="text" name="comment_name" id="comment-name" placeholder="Your name here...." required>
</label>
<label>
<span>Your comment *</span>
<textarea name="comment" id="comment" cols="30" rows="10" placeholder="Type your comment here...." required></textarea>
</label>
<input type="submit" id="submit_comment" value="Submit Comment">
</form>
这是我的剧本，但不起作用？我发送请求的地方。我想激活这样的scrpts以供参与者提交，有什么办法吗？
$(#form_post).submit(function(){
var form = $(form);
var submit = $('#submit_post');
form.on('submit', function(e) {
// prevent default action
e.preventDefault();
// send ajax request
$.ajax({
url: 'ajax_post.php',
type: 'POST',
cache: false,
data: form.serialize(), //form serizlize data
beforeSend: function(){
// change submit button value text and disabled it
submit.val('Submitting...').attr('disabled', 'disabled');
},
success: function(data){
// Append with fadeIn see http://stackoverflow.com/a/978731
var item = $(data).hide().fadeIn(500);
$('.wrap').append(item);
// reset form and button
form.trigger('reset');
submit.val('Submit Post').removeAttr('disabled');
},
error: function(e){
alert(e);
}
});
});
})；
$(#form_comment).submit(function(){
var form = $(form);
var submit = $('#submit_comment');
form.on('submit', function(e) {
// prevent default action
e.preventDefault();
// send ajax request
$.ajax({
url: 'ajax_comment.php',
type: 'POST',
cache: false,
data: form.serialize(), //form serizlize data
beforeSend: function(){
// change submit button value text and disabled it
submit.val('Submitting...').attr('disabled', 'disabled');
},
success: function(data){
// Append with fadeIn see http://stackoverflow.com/a/978731
var item = $(data).hide().fadeIn(500);
$('.comment-block').append(item);
// reset form and button
form.trigger('reset');
submit.val('Submit Comment').removeAttr('disabled');
},
error: function(e){
alert(e);
}
});
});
})；
您错过了一些"它应该是$（"#form_comment"）和$（"#form_post"）。。。
这对我有效：
$('#form_post').on('submit', function(event){
event.preventDefault();
$.ajax({
...
...
...
});
});
$('#form_comment').on('submit', function(event){
event.preventDefault();
$.ajax({
...
...
...
});
});
使用这样的提交事件，
$('body').on('submit', '#form_comment', function(){
e.preventDefault();
$.ajax({
...
...
...
});
});
$('body').on('submit', '#form_post', function(){
e.preventDefault();
$.ajax({
...
...
...
});
});
