facebook反应按钮/ javascript只在PHP循环中被调用一次

时间：2016-06-18 23:49:32

标签： javascript php jquery css facebook

我正在尝试将facebook动画反应表情符号整合到我的网站上，并且很惊讶没有太多关于它的消息来源。其实我差不多完成了。我发现了很好的脚本，并根据我的目的对其进行了修改，并乐意与您分享。但它只适用于我想要的一个帖子。当页面有多个可以喜欢的帖子时会出现问题。我发现javascript在php循环中不会被调用多次，也不知道为什么。我都试图在外部和内部保持JavaScript。没工作。这是我的代码。为了演示目的，我在片段中的html部分添加了一些php行。有任何想法吗？

你应该不在fetch环中插入Javascript functions。

效果是输出你的功能，就像你有行一样。

所以这样的事情显然不会起作用：

<script>
function something(){
    // code
}
</script>

<!-- some HTML for row[0]-->

<script>
function something(){
    // code
}
</script>

<!-- some HTML for row[1]-->

<script>
function something(){
    // code
}
</script>

<!-- some HTML for row[2]-->

<!-- and so on... -->

你应该马上看到函数something()被定义了不止一次......
这很糟糕。
我认为这是你面临的问题。
