如何从此输入中获取数据选择的值？假设我只想要其中的“ title”值？
$( document ).ready(function() {
//console.log("prdcl ready");
$("#digital_object_prdcls__0__prdcl_links__0__ref_").on('keyup change', prdcl_link);
$("#digital_object_prdcls__0__volume_num_").on('keyup change', prdcl_link);
$("#digital_object_prdcls__0__issue_num_").on('keyup change', prdcl_link);
function prdcl_link(){
//console.log("entered function");
var valp = {};
valp = $("#digital_object_prdcls__0__prdcl_links__0__ref_").data('data-selected');
console.log(valp);
var valv = $("#digital_object_prdcls__0__volume_num_").val();
//console.log(valv);
var vali = $("#digital_object_prdcls__0__issue_num_").val();
//console.log(vali);
};
});<input type="text" class="linker initialised" id="digital_object_prdcls__0__prdcl_links__0__ref_" data-label="Publication" data-label_plural="Publications" data-name="ref" data-path="digital_object[prdcls][0][prdcl_links][0]" data-url="/search.json" data-browse-url="/search.js?" data-selected="{"lock_version":0,"publication":"1111","publisher":"1111","title":"1111 (1111)","created_by":"admin","last_modified_by":"admin","create_time":"2016-06-01T14:46:46Z","system_mtime":"2016-06-01T14:46:46Z","user_mtime":"2016-06-01T14:46:46Z","jsonmodel_type":"prdcl_title","uri":"/prdcl_titles/9"}" data-multiplicity="one" data-format_template="title" data-types="["prdcl_title"]" style="display: none;">不要data-在代码中使用属性的第一块：
valp = $("#digital_object_prdcls__0__prdcl_links__0__ref_").data('selected');
