请参阅下面我对此问题的回答。它基于Kevin的输入，关于堆栈溢出的另一个问题加上一些反复试验。
我正在尝试做一些我认为相当简单的事情，但我一直都在失败。我的页面上有一个表单，用户可以选中一个框，使用javascript SDK将其输入发布到他们的Facebook墙上。用户确认或取消发布到他们的Facebook墙后，我无法正常发布表单。具体来说，如果我只是在函数结尾处“返回true”或者如果我将return false添加到结尾，它或者不等待答案，但是将facebook返回true插入到我的回调函数中以进行facebook api调用，它等待我回答并按预期提交到Facebook墙，但后来什么也没做。
这是我的代码到目前为止（这是第二个例子，发布到Facebook很好但后来没有正常提交表单）：
<script type="text/javascript">
$(function() {
$('#search').submit(function() {
var type = $('#type').val();
if((type == 'o' || type == 'r') && $('#fb-publish').attr('checked') == true) {
var start = $('#start :selected').text();
var dest = $('#dest :selected').text();
var date = $('#datepicker').val();
var time = $('#time').val();
var seats = $('#spots').val();
var notes = $('#notes').val();
console.log('type: ',type);
if(type == "r") {
var begin = "I need a ride";
if(seats > 1) {
var end = " for "+seats+" people.";
}
else {
var end = '.';
}
}
else {
var begin = "I'm offering a ride";
if(seats > 1) {
var end = " for "+seats+" people.";
}
else {
var end = ' for 1 person.';
}
}
publishWallPost('{{ page.slug }}', notes, begin + " from " +start+" to " + dest + " on "+date+" at " + time + end);
return false;
}
else {
alert('you are browsing!');
return true;
}
});
});
</script>
<script>
<!--
function publishWallPost(slug, message, description) {
var attachment = {'name':'Backcountryride.com','description':description,'media':[{'type':'image','src':'http://dev.backcountryride.com/images/vanlogo.jpg','href':'http://backcountryride.com/' + slug + '/'}]};
FB.ui({
method: 'stream.publish',
message: message,
attachment: attachment,
user_message_prompt: 'post this ride to your wall?'
},
function(response) {
if (response && response.post_id) {
alert('Ride was published to your Facebook wall.');
return true;
} else {
alert('Ride was not published to your Facebook wall.');
return true;
}
});
}
//-->
</script>
这是我的表格，如果有任何帮助的话：
<form action="quick_process.php" method="post" name="search" id="search" >
<label for="type" id="quick_label1" >Choose Action</label>
<select name="type" size="1" id="type">

</select><br />

我想我知道你的问题是什么。当您在表单上运行提交功能时，它希望立即提交，但是，如果您在其上返回false，则表单将不会提交。你想要的是编写一个不同的函数来处理你的fb post ....然后在那个逻辑的结尾，你想做一个$('#search').submit();
所以举例......
$('#submitButton').click(function(e){
e.preventDefault();
[All your logic here in your original function]
publishWallPost('{{ page.slug }}', notes, begin + " from " +start+" to " + dest + " on "+date+" at " + time + end);
$('#search').submit();
});
您需要重写表单提交按钮，因为您不希望它首先使用表单的提交功能，您希望它首先运行您的新功能。
<input type="button" id="submitButton" value="Submit" name="submitme" class="form-submit" />
所以你在这里做的是....你想在表格上运行你的逻辑，然后你想做你的Facebook发帖，或者不....然后你运行实际提交的一旦你打电话给你的FB帖子就形成你的php帖子。
我希望这是有道理的。

如果将来有人试图这样做，这就是最终代码的样子。谢谢你kevin.mansel指出我正确的方向。我需要将submit（）添加到回调函数，并将表单的提交按钮添加到表单标签外，否则它会破坏javascript。这是javascript：
$(function() {
$('#submitButton').click(function(e) {
e.preventDefault();
var type = $('#type').val();
if((type == 'o' || type == 'r') && $('#fb-publish').attr('checked') == true) {
[logic from original post]
publishWallPost('{{ page.slug }}', notes, description);
}
else $('#search').submit();
});
});
</script>
<script>
<!--
function publishWallPost(slug, message, description) {
var attachment = {'name':'Backcountryride.com','description':description,'media':[{'type':'image','src':'http://dev.backcountryride.com/images/vanlogo.jpg','href':'http://backcountryride.com/' + slug + '/'}]};
FB.ui({
method: 'stream.publish',
message: message,
attachment: attachment,
user_message_prompt: 'post this ride to your wall?'
},
function(response) {
if (response && response.post_id) {
alert('Ride was published to your Facebook wall.');
$('#search').submit();
} else {
alert('Ride was not published to your Facebook wall.');
$('#search').submit();
}
});
}
//-->
</script>
以下是HTML表单：
<form action="quick_process.php" method="post" name="search" id="search" >
[form inputs]
</form>
<input type="submit" value="Submit" name="submit" class="form-submit" id="submitButton" />
请注意，提交按钮位于表单标记之外（或者它可以是链接或图像，也可以是绑定了点击事件的任何内容。）
