Question

我在iframe中有几个关于php内容的问题。

我想创建一些导航链接并定位iframe。有简单的方法吗？
你认为我只能用Ajax或Ahah做到这一点吗？
这是我到目前为止所尝试的，但它不起作用。

这是我的代码。

      // HERE ARE NAVIGATION LINKS

        <header>
        <h1>Välkommen till Min Sida</h1><br>
            <nav>
                <a href="index.php?go=welcome">HOME</a>
                <a href="index.php?go=about">ABOUT ME</a>
                <a href="index.php?go=contact">CONTACT</a>
                <a href="index.php?go=subscribtion">SUBSCRIBE</a>
            </nav>
        </header>


    // HERE IS MY IFRAME WHERE I WANT TO OPEN MY PHP FILES  



<div class='content' >
  <iframe>

    <?php

$go = @$_GET["go"];

            switch($go){


    // IF I CLICK ON "WELCOME" FROM THE NAVIGATION BAR, OPEN THIS LINK IN My IFRAME

                case "welcome";
                include("welcome.php");
                break;


    // IF I CLICK ON "ABOUT" FROM THE NAVIGATION BAR, THIS LINK IN MY IFRAME





 case "about";
        include("newarrivals.php");
        break;


 // AS "DEFAULT", SHOW THIS IN THE IFRAME

    default;
    echo 

            <figure>
            <img src="figure.png"  alt="Figure 1" style="max-width:80%; height:auto;">
            <figcaption> <h6> Illustration: Mehmet Akb. </h6> </figcaption>
            </figure>

break;
}
?>

</iframe> 
</div>
</div>
</body>

Answer 1

您可以使用javascript重新加载iframe

将您的iframe内容移至<iframe id="contentFrame"></iframe>
在iframe <a href="javascript:void(0)" onclick="goto('icontent.php?go=welcome')">HOME</a> <a href="javascript:void(0)" onclick="goto('icontent.php?go=about')">ABOUT ME</a> <a href="javascript:void(0)" onclick="goto('icontent.php?go=contact')">CONTACT</a> <a href="javascript:void(0)" onclick="goto('icontent.php?go=subscribtion')">SUBSCRIBE</a>

更改您的链接操作

function goto(url) {
    document.getElementById("contentFrame").contentWindow.location.replace(url);
}

创建此javascript函数

override func viewDidAppear(animated: Bool) {
    self.giphyBackground(Title: "dancing") { [weak self] (gifUrl) -> Void in
        let gifView = FLAnimatedImageView(frame: self!.giphy.frame)
        gifView.animatedImage = FLAnimatedImage(animatedGIFData: NSData(contentsOfURL: NSURL(string: gifUrl)!)!)
        self?.view.insertSubview(gifView, aboveSubview: self!.giphy)
    }
}

Answer 2

如果您的Iframe有名称，您可以使用目标属性来确定iframe名称，例如

<iframe name="topframe"></iframe>
<a href="xxx" target="topframe">

使用iframe和PHP
