自定义jQuery - 将数据过滤器添加到

I need make a modification to a custom jQuery script.

我需要修改自定义的jQuery脚本。

I've got a custom jQuery script which does the following:

我有一个自定义的jQuery脚本,它执行以下操作:

• it converts a standard HTML un-ordered list into a <select> dropdown

它将标准HTML无序列表转换为下拉列表

• it converts the list-items to clickable <options>

它将列表项转换为可点击的

• the <select> is hidden on desktop and only shown on mobile

隐藏在桌面上,仅显示在移动设备上

• all of this works great and here's a screenshot:

所有这些都很棒,这是一个截图:

All is working well, however I need an additional attribute to be added to each <option>

一切都运行良好,但是我需要在每个中添加一个额外的属性

• Notice how each HTML list item has (data-filter=".term-x")

注意每个HTML列表项的具体方式(data-filter =“。term-x”)

• I need this to also be added to each <option> in the <select> dropdown

我还需要将其添加到下拉列表中的每个

Here's what the final HTML output looks like on the page after script has run and done it's thing:

以下是脚本运行完成后页面上最终HTML输出的样子:

<div id="horizontal_nav">
<ul class="sub-menu">
    <li><a href="http://localhost.local/site/horizontal-nav/" data-filter=".term-3"><span><strong>Horizontal Nav</strong></span></a></li>
    <li><a href="http://localhost.local/site/full-width/" data-filter=".term-4"><span><strong>Full Width</strong></span></a></li>
    <li><a href="http://localhost.local/site/blog/" data-filter=".term-3"><span><strong>Blog</strong></span></a></li>
    <li><a href="http://localhost.local/site/cart/" data-filter=".term-4"><span><strong>Cart</strong></span></a></li>
    <li><a href="http://localhost.local/site/checkout/" data-filter=".term-5"><span><strong>Checkout</strong></span></a></li>
    <li><a href="http://localhost.local/site/features/" data-filter=".term-5"><span><strong>Features</strong></span></a></li>
</ul>
<select>
    <option selected="selected" value="">More in this section...</option>
    <option value="http://localhost.local/site/horizontal-nav/">Horizontal Nav</option>
    <option value="http://localhost.local/site/full-width/">Full Width</option>
    <option value="http://localhost.local/site/blog/">Blog</option>
    <option value="http://localhost.local/site/cart/">Cart</option>
    <option value="http://localhost.local/site/checkout/">Checkout</option>
    <option value="http://localhost.local/site/features/">Features</option>
</select>
</div>

Here's the jQuery that creates the <select> and needs the modification mentioned above

这是创建的jQuery,需要上面提到的修改

    jQuery(document).ready(function () {

    jQuery("<select />").appendTo("#horizontal_nav");
    jQuery("<option />", {
        "selected": "selected",
        "value": "",
        "text": php_data.mobile_sub_menu_text
    }).appendTo("#horizontal_nav select");
    jQuery("#horizontal_nav a").each(function() {
        var el = jQuery(this);
        jQuery("<option />", {
            "value": el.attr("href"),
            "text": el.text()
        }).appendTo("#horizontal_nav select")
    });
    jQuery("#horizontal_nav select").change(function() {
        window.location = jQuery(this).find("option:selected").val()
    })
};

});

jQuery(document).ready(function() {

  jQuery("<select />").appendTo("#horizontal_nav");
  jQuery("<option />", {
    "selected": "selected",
    "value": ""
  }).appendTo("#horizontal_nav select");
  jQuery("#horizontal_nav a").each(function() {
    var el = jQuery(this);
    jQuery("<option />", {
      "value": el.attr("href"),
      "text": el.text(),
      "data-filter": el.attr('data-filter')//add it here
    }).appendTo("#horizontal_nav select")
  });
  jQuery("#horizontal_nav select").change(function() {
    window.location = jQuery(this).find("option:selected").val()
  })


});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="horizontal_nav">
  <ul class="sub-menu">
    <li><a href="http://localhost.local/site/horizontal-nav/" data-filter=".term-3"><span><strong>Horizontal Nav</strong></span></a>
    </li>
    <li><a href="http://localhost.local/site/full-width/" data-filter=".term-4"><span><strong>Full Width</strong></span></a>
    </li>
    <li><a href="http://localhost.local/site/blog/" data-filter=".term-3"><span><strong>Blog</strong></span></a>
    </li>
    <li><a href="http://localhost.local/site/cart/" data-filter=".term-4"><span><strong>Cart</strong></span></a>
    </li>
    <li><a href="http://localhost.local/site/checkout/" data-filter=".term-5"><span><strong>Checkout</strong></span></a>
    </li>
    <li><a href="http://localhost.local/site/features/" data-filter=".term-5"><span><strong>Features</strong></span></a>
    </li>
  </ul>
</div>

add an .attr() name it data-filter then append the data-filter from the ul

添加一个.attr()名称,数据过滤器然后从ul附加数据过滤器
