jquery:查找除触发该函数的值之外的所有其他值

Question

通过用户单击“添加”按钮来克隆具有左类的 div。所以它是多个。

我需要找到除触发此函数的类(class)之外的所有其他类(class)的当前值[已在“changed_course”变量中找到该值]

<div id="ds_relation_main_block">




<div class="left">
    <select name="course[]" class="input-block-level course">
        <option value="55" selected="selected">BBA</option>
        <option value="56">BSc</option>
        <option value="57">BIT</option>
    </select> <!-- end of select -->
</div> <!-- end of left -->

<div class="left">
    <select name="course[]" class="input-block-level course">
        <option value="55" selected="selected">BBA</option>
        <option value="56">BSc</option>
        <option value="57">BIT</option>
    </select> <!-- end of select -->
</div> <!-- end of left -->

<div class="left">
    <select name="course[]" class="input-block-level course">
        <option value="55" selected="selected">BBA</option>
        <option value="56">BSc</option>
        <option value="57">BIT</option>
    </select> <!-- end of select -->
</div> <!-- end of left -->

<script>
jQuery(function($) {
    $('.course').change(function(evt) {
        var changed_course = $(this).find('option:selected').val();
        //console.log(changed_course);

        //need to find all other course's current values 
        //except the one which triggered this function [ already found the value in //"changed_course" variable ]
    });

});

Answer 1

这应该可以解决问题:

var otherValues = $('.course').not(this).map(function() {
    return this.value
}).get();
