Question

我对编码很陌生，所以请耐心等待（我甚至不知道我想做什么是可能的）。我正在尝试为新网页创建一个联接页面，这需要人们选择他们知道如何做的多种技能，并且想知道该怎么做。

一旦选择了技能，我需要一个140char的盒子来弹出解释。我已经拥有了所有技能设置的数据库。有11个主要技能组，其下有许多孩子，每个都有一个parent_id和特定的skill_id。

我找到了一个名为"JQuery multi level accordion menu"的菜单。我无法弄清楚如何动态调用所有技能，所以我刚刚在那里硬编码。我能够把它们列出来，但不能用手风琴。如果有人有任何想法，请告诉我。

我遇到的主要问题是我需要菜单像表单一样工作，以便我可以POST选择哪些技能，以及它的140char盒子。由于菜单需要技巧为ahref，我不知道如何将其转换为表单选项。这是菜单的前两个元素......

任何想法？如果我没有包含任何必要的代码，请告诉我们！

Answer 1

如果您希望锚标记执行POST请求，则需要查看jQuery.post()方法。如果您希望它执行表单提交，则使用submit()方法。查看jQuery文档以查看两者是如何工作的，但是从代码的外观来看，因为您没有实际的<form>，您很可能需要jQuery.post

在任何一种情况下，您需要的是锚标记上的单击事件侦听器。如下所示：

<script>
jQuery("a").click(function(evt) {
        //this function gets called every time an <a> tag is clicked
        //evt contains information about the event
        //look at it in Chrome Developer tools to see it
        console.log(evt); //logging the event object so you can see what it contains
        jQuery.post(YOUR CODE HERE);
});
</script>

很抱歉，如果我过度简化了任何内容（你说你不熟悉编码）。

<a href=""> form option? dynamic Jquery</a>
