div的附加文本和编辑文本-按钮单击事件 [英] Appending text and editing text of div - button click event

问题描述

我正在使用div元素和jquery.我能够创建一个新的div并通过按钮单击事件附加文本.借助于jqueryui插件，创建的每个div都具有可拖动属性.另外，我也可以通过onclick事件删除单个div.但是我遇到了这个实现问题:由于我能够在单击按钮时将文本附加到div上.如何编辑以前创建的div的文本? JSFIDDLE

I am working with div elements and jquery. I am able to create a new div and append text through an on button click event. Each div created has draggable property thanks to a jqueryui plugn. Also, I am able to delete individual divs through an onclick event as well. But I am running into this implementation issue: Since I am able to append text to a div on a button click. How can edit the text of a previously created div? JSFIDDLE

jQuery

/** Remove newly created div **/
$(".remove").click(function(){
    $(".draggable").remove();
});

var z = 1;
$('#button').click(function (e) {
    /** Make div draggable **/
    $('<div />', {
        class: 'draggable ui-widget-content',
        html: '<span class="close">[X]</span><span class="text">' + $('textarea').val() + '</span>',
        appendTo: '.middle-side',
        draggable: {
            containment: 'parent',
            start: function( event, ui ) {
                $(this).css('z-index', ++z);
            }
        }
    }).addClass('placement');


    /** Contain draggable div **/
    $('.middle-side').parent().mousemove(function(e){
        var offset = $(this).offset();
        var relX = e.pageX - offset.left;
        var relY = e.pageY - offset.top;
        $('.placement').css({'top': relY + 30,'left': relX + 10, 'position': 'absolute'});
    })

});

$('body').on('click', '.draggable .close', function () {
    $(this).closest('.draggable').remove();
});

HTML

<textarea rows="4" cols="50" placeholder="Enter Text Here!"></textarea>
<br/>
<input type="button" id="button" value="Add Div with Text" />
<br/>
<div>
    <div class="middle-side empty"></div>

</div>

推荐答案

由于您已经在使用jQuery-ui，如何使用对话框?

As you are already using jQuery-ui - what about using a dialog?

这是一个(未样式化的)示例.正如 Geraud Mathe 所建议的那样，我使用了dblclick()事件:

Here is an (unstyled) example. As Geraud Mathe suggested I used the dblclick() Event:

JSFiddle | 对话框文档

theDivJustAdded.dblclick(function() {
        var divElem = $(this);
        dialog = $( "#dialog-form" ).dialog({
            height: 300,
            width: 350,
            modal: true,
            buttons: {
                "Save": function() {
                    divElem.find('.text').text($( "#dialog-form input" ).val());
                    dialog.dialog( "close" );
                },
                Cancel: function() {
                    dialog.dialog( "close" );
                }
            }
        });

    }
);
