Question

我在显示信使的页面<section id="parent"> <header>Parent flex header </header> <section id="child" > <header>Child flex header</header> <article> Lots of content. Lots of content. Lots of content. Lots of content. Lots of content. Lots of content. Lots of content. Lots of content. Lots of content. Lots of content. Lots of content. Lots of content. Lots of content. Lots of content. Lots of content. Lots of content. Lots of content. Lots of content. Lots of content. Lots of content. Lots of content. Lots of content. Lots of content. Lots of content. Lots of content. Lots of content. Lots of content. Lots of content. Lots of content. Lots of content. Lots of content. Lots of content. Lots of content. </article> <footer>Child flex footer</footer> </section> <footer>Parent flex footer</footer> </section>内有此代码......

PHP：

<div id="chtmsg">

效果很好。所以，我想用js加载它来刷新div #chtmsg内的所有新消息，然后我创建了一个文件msg.php并且if($perguntas){ for($c=0;$c<count($perguntas);$c++){ $perguntas[$c]->tipo == 'F' ? $class = 'message_F' : $class = 'message_P'; $hora = substr($perguntas[$c]->hora, 0, 5); echo "<li class=\"".$class."\">".$perguntas[$c]->mensagem."".$pergunta->databr($perguntas[$c]->data)." - ".$hora."</li>"; if($perguntas[$c]->tipo=='F' and $perguntas[$c]->status == 0){ $pergunta->marcaRespLida($perguntas[$c]->id); } } }它继续工作正常，但是使用js我需要放入路径...

HTML：

<?php include("msg");?>

但是它显示了de div中的错误......

注意：未定义的变量：第3行的/Applications/XAMPP/xamppfiles/htdocs/sisconbr-sistema-novo/site/modulos/produto/msg.php中的perguntas

我测试了msg.php文件中的其他代码，没有变量就可以正常工作......

Answer 1

只是一个想法...

PHP的第一行

if($perguntas){

或许应检查是否定义如此

if(isset($perguntas)){

我的建议在另一个答案中解释here

为了获得更好的代码，您最好使用：

class MSC_CLItem_Tizer : MSC_CLItem
{
    var Title:String!
    var Video:MSC_CLItem_TizerVideo!
    var Detail:MSC_CLItem_TizerDetail!

    private init(title:String!)
    {
        super.init()
        self.Title = title
        super.Type = .Tizer
    }

    override func RenderUI(Point:CGPoint) -> UIView
    {
        let v = UIImageView()
        v.backgroundColor = UIColor.yellowColor()
        let screenSize: CGRect = UIScreen.mainScreen().bounds
        v.frame.size = CGSize(width: screenSize.width - 10, height: CGFloat(160))
        v.frame.origin = Point

        let vid = UIImageView()
        vid.image = UIImage(named: "default")
        vid.backgroundColor = UIColor.grayColor()
        vid.contentMode = .ScaleAspectFill
        vid.af_setImageWithURL(NSURL(string: "Image HTTP url")!)
        vid.frame.size = v.frame.size
        vid.frame.origin = CGPoint(x: 0, y: 0)
        vid.clipsToBounds = true
        vid.userInteractionEnabled = true
        v.userInteractionEnabled = true
        let tapRecognizer = UITapGestureRecognizer(target: self, action: Selector("imageTapped:"))
        vid.addGestureRecognizer(tapRecognizer)
        v.addSubview(vid)
    }

    func imageTapped(gestureRecognizer: UITapGestureRecognizer) {
        //Not detected to here
    }
}
