所以,这很奇怪,大约一个月前,它在我做了一堆代码更新之前对我有用。无论如何,问题是实时提交处理程序甚至不会在IE8中运行,但是,如果我在按钮单击上运行它,它的工作原理。见下文:
HTML
<label>Add Attachment</label>
<form class="file_upload" method="post" enctype="multipart/form-data" target="upload_target" action="">
<input name="binary" id="file" size="27" type="file" /><br />
<br><input type="submit" name="action" value="Upload" /><br />
<input type="button" class="test" value="test">
<iframe class="upload_target" name="upload_target" src="" style=""></iframe>
</form>
<label>Attachments</label>
<ul class="upload_output">
<li class="nofiles">(No Files Added, Yet)</li>
</ul>
JavaScript的:
function file_upload($theform,item_id){
$theform.attr('ACTION','io.cfm?action=updateitemfile&item_id='+item_id);
if($theform.find('[type=file]').val().length > 0){
$('iframe').one('load',function(){
$livepreview.agenda({
action:'get',
id:item_id,
type:'item',
callback:function(json){
$theform.siblings('.upload_output').append('<li style="display:none" class="file-upload"><a target="blank" href="io.cfm?action=getitemfile&item_file_id='+json[0].files.slice(-1)[0].item_file_id+'">'+json[0].files.slice(-1)[0].file_name+'</a> <a style="color:red" title="Delete file?" href="#deletefile-'+json[0].files.slice(-1)[0].item_file_id+'">[X]</a></li>').children('li').fadeIn();
$theform.siblings('.upload_output').find('.nofiles').remove();
}
});
//Resets the file input. The only way to get it cross browser compatible as resetting the val to nothing
//Doesn't work in IE8. It ignores val('') to reset it.
$theform.append('<input type="reset" style="display:none">').children('[type=reset]').click().remove();
});
}
else{
$.alert('No file selected');
return false;
}
}
/* FILE UPLOAD EVENTS */
//When they select "upload" in the modal
$('.file_upload').live('submit',function(event){
alert('hello world');
file_upload($('.agenda-modal .file_upload'),$('.agenda-modal').attr('data-defaultitemid'));
});
/* This is the code that makes it work..., but i dont want it! it should alert hello world on the submit button! */
$('.test').live('click',function(event){
$('.file_upload').submit();
});

这是设计上的,并没有完全与IE 8隔离。在所有浏览器中一直都是这样。
如果您调用submit
方法,只有在使用提交按钮提交表单时才会发生submit
事件。

而不是创建重置按钮,模拟点击事件并销毁它 - 为什么不只是
$('.file_upload').reset();
您真的需要直播才能提交表单吗?如果按钮始终保留在DOM中,请使用正常的点击事件,如
$('.test').click(function(){
$('.file_upload').submit();
});
