我正试图找出一种方法来自动选择一个基于传递变量的选项，该选项仅匹配该选项的值。

<label>
    <span>Font Type</span>
    <select id="options>
        <option value="one">One</option>
        <option value="two" selected>Two</option>
        <option value="three">Three</option>
    </select>
</label>

function loadSelect(userFont){
    $('#options').find('option[value='+userFont+']').attr('selected', 'selected');
}

loadSelect(three);

Answer 1

只需在<select>标记上设置值：

$('#options').val(userFont);

$(function() {
  $("#options").val("three");
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<select id="options">
  <option value="one">One</option>
  <option value="two" selected>Two</option>
  <option value="three">Three</option>
</select>
