我在项目可嵌套列表扩展中使用。如何使用此列表中的jquery,键和值来阅读?

List的代码如下所示:

<div class="dd" id="list1">
    <ol class="dd-list">
        <li class="dd-item" data-id="1">Item 1</li>
        <li class="dd-item" data-id="2">Item 2</li>
        <li class="dd-item" data-id="3">Item 3</li>
        <li class="dd-item" data-id="4">Item 4</li>
        <li class="dd-item" data-id="5">Item 5</li>
    </ol>
</div>

序列化输出如下所示:

  

[{ “ID”:1},{ “ID”:2},{ “ID”:3},{ “ID”:4},{ “ID”:5}]

此输出由此javascript代码生成:

<script type="text/javascript">
    $('.dd').nestable();
    //Watch for list changes and show serialized output
    function update_out(selector, sel2){
        var out = $(selector).nestable('serialize');
        $(sel2).html(window.JSON.stringify(out));
    }

    update_out('#list1',"#out1");

    $('#list1').on('change', function() {
        update_out('#list1',"#out1");
    });  
</script>

请参阅答案here

var test = [{"id":1},{"id":2},{"id":3},{"id":4},{"id":5}]    
var result = test.filter(function( obj) {
  return obj.id == 1;
});
