jquery - jQuery onclick if then 条件 window.location.href 问题

Question

好的，所以我正在尝试使用我在这里找到的一个很酷的图像加载器/图库，称为 ShineTime。

我想采用它来类似于我主页上的产品查看器，您可以在其中查看我为它保留的空白区域。

现在，由于我需要将其调整为产品查看器，因此我想要链接到我正在预览的产品或服务。

我在代码中创建了一个条件，您可以在下面看到，我将在此处突出显示：

$('#thumb1').click(function()
     {
       if($('#largephoto').click())
       {
         window.location.href = 'http://www.marioplanet.com/product.asp?IDnum=1';
        }
        else
        {
        }
     });

如您所见，我正在尝试将其设置为单击thumb1元素的位置，一个包含我的第一个小缩略图的 div，如果然后单击largephotodiv，我的较大预览照片所在的位置，那么它将带我到上面的链接。但是，由于某种原因，当我单击缩略图时，它无法正常工作。当我单击缩略图时，它将直接将我带到链接。我认为这可能是由于下面的一些 jQuery 代码，所以我在这里包含了完整的代码：

     function loadPhoto($url, $caption)

        showPreloader();

这段代码：

$('#thumb1').click(function()
{
    if($('#largephoto').click())
    {
        window.location.href = 'http://www.marioplanet.com/product.asp?IDnum=1';
    }
});

...没有被用作 jQuery 的意图。现在，它说：“当我点击 'thumb1' 时，通过调用click()'#largephoto' 检查是否返回了非空值。该 if 语句将始终为非空值（因此它是true），这就是为什么你被直接带到你的链接。你实际上是在以编程方式点击你的 largephoto 链接，而不是等待它被点击。

听起来您正在尝试捕获一系列点击事件。您可能需要在 thumb1 点击事件中设置一个变量，然后在 largephoto 点击事件中检查它。就像是：

var thumbClicked = false;

$('#thumb1').click(function()
{
    thumbClicked = true;
});

$('#largephoto').click(function()
{
    if (thumbClicked)
    {
        window.location.href = 'http://www.marioplanet.com/product.asp?IDnum=1';
    }
});

首先尝试使用所有拇指上的类说 class="thumbclass"。显然你需要调整它，但你可以看到我们解析了产品编号的 ID，然后 URL 可以是动态的。通过使用一个通用类，我们可以使点击事件适用于所有拇指。可能需要微调。

var str ='',
productID='';

$('.thumbclass').click(function(){
str = this.attr("id");
productID = str.match(/[0-9]/);
})
$('#largephoto').click(function(){
  if(productID != ''){
     window.location.href= 'http://www.marioplanet.com/product.asp?IDnum='+productID
  };
})

jquery - jQuery onclick if then 条件 window.location.href 问题
