如何從所選元素中獲取數據？

Question

頁面包含html

<ol id="selectable">
    <li class="ui-widget-content word">I've</li>
    <li class="ui-widget-content word">got</li>
    <li class="ui-widget-content word">a</li>
    <li class="ui-widget-content word">job</li>
</ol>

我嘗試從li元素獲取數據

$(function() {
    $("#selectable").selectable({
        stop : function() {
            var result = $("#select-result");
            $(".ui-selected", this).each(function() {   
                //getting data from an element
                var value = $("#selectable li").data(this);
                console.log("value"+value); //this outputs to `value[object Object]`    
            });
        }
    });

});

Answer 1

我想你需要li元素內的文本

console.log($(this).text());

我會這樣

$('.ui-widget-content').click(function(){
     console.log($(this).text());
});

Answer 2

你可以這樣做：

function getDATA(){    
    var data;
    $("#selectable li").each(function() {
         data += $(this).text();
    })

    console.log(data);
}

您可以使用選擇的屬性

 $( "#selectable" ).selectable({ selected: function( e, ui ) { if ($( ui.selected ).hasClass( "ui-state-highlight" )) { $( ui.selected ).removeClass( "ui-state-highlight" ); } else { $( ui.selected ).addClass( "ui-state-highlight" ); } console.log(ui.selected.innerHTML); }, unselected: function( e, ui ) { $( ui.unselected ).removeClass( "ui-state-highlight" ); } }); 

 ul {margin: 0; padding: 0; list-style-type: none; width: 50%;} ul li {padding: 0.4em; margin: 0.2em; cursor: pointer; font-size: 0.8em;}

Answer 4

為什么不只是使用

 var foo = $('#selectable').find(':selected').data('id'); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script> <ol id="selectable"> <li data-id="I've" class="ui-widget-content word">I've</li> <li data-id="got" class="ui-widget-content word">got</li> <li data-id="a" class="ui-widget-content word">a</li> <li data-id="job" class="ui-widget-content word">job</li> </ol>
