我正在使用Malsup的AJax表单插件。Ajax表单多次提交。有时
我去过的是一个“聊天”页面,基本上是一个每隔2秒刷新一次的div,并在用户向聊天窗口提交内容时进行刷新。页面的
粗糙HTML布局:
<div id='refresh_openmsg'>
<div id='chatdiv'>Chat window here</div>
</div>
<div id='reply_block'>
<form id='send_msg_form'>Basic form goes here</form>
</div>
JS:
//create timer to refresh chat window every 2 seconds
<script type='text/javascript'>
$(document).ready(function() {
refresh_openmsg = setInterval(function(){$('#refresh_openmsg').load('messaging.php?view='+the_page+' #refresh_openmsg');}, 2000);
});
</script>
//This is what happens when the form is submitted
<script type='text/javascript'>
$(document).ready(function() {
var options = {
target: '',
dataType: 'html',
beforeSubmit: showRequest_sendmsg,
success: showResponse_sendmsg
};
$('#send_msg_form').live('submit', function() {
$(this).ajaxSubmit(options);
return false;
});
});
function showRequest_sendmsg(formData, jqForm, options) {
return true;
}
function showResponse_sendmsg(responseText, statusText, xhr, $form) {
$("#reply_block").load('messaging.php?view='+the_page+' #reply_block', function() {
$('#reply_area').focus();
$("#refresh_openmsg").load('messaging.php?view='+the_page+' #refresh_openmsg', function() {
$("html, body").animate({ scrollTop: $(document).height() }, 500);
});
}).focus();
}
</script>
//on showResponse, I'm reloading the #reply_block div, and reloading the #refresh_openmsg div (#refresh_openmsg div is also being reloaded every 2 seconds)
我遇到的问题是,窗体被提交多次,有时两次,有时是3次,有时甚至是4或5.非常奇怪,我之前建立过类似的网页,并且从未遇到过这个问题。我知道这是我的代码,并永不结束刷新,但这是我目前唯一的选择。任何人都看到这个问题?
提交表单时,我已经尝试在.live事件之前放入.die(),但没有解决问题。
隐而不宣只有在提交表单时才会触发这种情况? – DanielOlivasJr
是的,它会在表单提交时被触发,但是因为您一次又一次地重新加载此页面,多个侦听器正在连接 – mprabhat
如果我添加$(“#send_msg_form”)。到 – DanielOlivasJr
