双击可拖动项 [英] Apply double click on draggable items

问题描述

我有一个黄色按钮，可以将其拖放到灰色面板上.我使用"handleDragStop"功能来处理用户拖放黄色按钮时需要完成的所有任务.一切都很好.但是，我不知道如何启用用户双击黄色按钮并具有与拖放相同的行为?

I have a yellow button that can be dragged and dropped on the gray panel. I use "handleDragStop" function to handle all the tasks that need to be done when users drag and drop the yellow button. Everything works great. However, I wonder how do I enable the behavior where users double click on the yellow button and have the same behavior as when they drag and drop?

$(".top-icon").draggable({
        connectToSortable: '#content',
        helper: myHelper,
        stop: handleDragStop
});

function handleDragStop(event, ui) {
        var current_text = '<div class="color-box"><b>Yellow Box ' + i + '</b>' + '<div class="yellow-content">' + '<div class="item">Item 1</div>' + '<div class="item">Item 2</div>' + '<div class="item">Item 3</div>' + '<div class="add-item">Add New Item</div>' + '</div>' + '</div>';
        $('#content .top-icon').after(current_text);

        i++;

        var $new_insert_item = $('#content .top-icon').next();
        $('#content .top-icon').remove(); // remove the clone .top-icon inside #content

        console.log('hi');
        // when click on Add New Item button
}
// end of handleDragStop

像这样调用draggable之后，我可以应用dblclick事件:

I can apply dblclick event after calling draggable like this:

$(".top-icon").draggable({
        connectToSortable: '#content',
        helper: myHelper,
        stop: handleDragStop
})
.dblclick(function() {

    alert('hi');
    // Do the same tasks as handleDragStop....

});

但是，我想知道是否有一种方法可以共享可拖动对象和dblclick的handleDragStop功能，这样我就不需要维护可拖动对象的handleDragStop函数和另一个类似dblcclick的handleDragStop函数吗?谢谢您的帮助.

However, I wonder if there is a way I can share the functionality of handleDragStop for both draggable and dblclick so that I don't need to maintain a function handleDragStop for draggable and another similar function as handleDragStop for dblcclick? Thank you for your help.

这是 jsfiddle

推荐答案

您的handleDragStop()函数在两个事件处理程序中均应正常工作.其中唯一可拖动的特定代码是$('#content .top-icon').after(current_text);和CMIIW，但我不明白为什么您不能同样出色地执行$('#content').append(current_text);，这在两种情况下均有效.试试这个: http://jsfiddle.net/tonicboy/Tt7Fb/

Your handleDragStop() function should work fine in both event handlers. The only draggable-specific code in it was $('#content .top-icon').after(current_text); and CMIIW but I don't see why you couldn't do $('#content').append(current_text); just as well, which would work in both cases. Try this: http://jsfiddle.net/tonicboy/Tt7Fb/

JS:

$(function () {

    $('#content').sortable({
        placeholder: 'ui-state-highlight'
    });


    $(".top-icon").draggable({
        connectToSortable: '#content',
        helper: myHelper,
        stop: handleDragStop
    }).dblclick(function(e) {

    handleDragStop(e);

});;


    function myHelper(event) {
        return $(this).clone();
    }

    var i = 1;

    function handleDragStop(event, ui) {
        debugger;

        var current_text = '<div class="color-box"><b>Yellow Box ' + i + '</b>' + '<div class="yellow-content">' + '<div class="item">Item 1</div>' + '<div class="item">Item 2</div>' + '<div class="item">Item 3</div>' + '<div class="add-item">Add New Item</div>' + '</div>' + '</div>';
        $('#content').append(current_text);

        i++;

        var $new_insert_item = $('#content .top-icon').next();
        $('#content .top-icon').remove(); // remove the clone .top-icon inside #content

        console.log('hi');
        // when click on Add New Item button



    }
    // end of handleDragStop


    $('#content').on('click', '.add-item', function () {

        var $this = $(this);
        var item_count = $this.siblings('.item').length + 1;
        console.log(item_count);

        var str_item = '';
        str_item = '<div class="item">Item ' + item_count + '</div>';

        $(str_item).insertBefore($this);


    });
});
