我在jqxtree画了一棵树。我必须拖动树元素并绘制一个小方框div并附加到div processFlowId
。
dragAndDrop代码
$( ".dragItem" ).draggable({ revert: true,
revertDuration: 0,
cancel : 'span',
refreshPositions: true
//,containment: "parent"
,helper: 'clone'});
$('#jqxTree').jqxTree({
height: '200px',
width: '300px',
theme: 'energyblue',
allowDrag: true,
allowDrop: false
});
$(".dragItem").css({"position": ""});
var itemFlag =0;
$("#acceptDrop").droppable({
accept: ".dragItem",
activeClass: "drop-active",
hoverClass: "drop-hover",
drop: function (event, ui) {
var itemid = ui.draggable.attr("id");
itemFlag++
drawAttrList(itemid + "_" + itemFlag,itemid,"processElement",ui);
}
});
function drawAttrList(mainDivId, droppedToolId, dataMiningType,ui) {
var html = '<div class="mouseHover" id="'+ mainDivId+ '"'
+ 'style="width:200px;"'+'><div class="widget-box w"><div class="widget-header" title="'+ mainDivId+ '">';
html += '<h4 class="lighter smaller" onclick="openProperties(\''
+ mainDivId + '\',\'' + dataMiningType
+ '\')"><i class="icon-random blue"></i>' + droppedToolId + '</h4>';
html += '</div>';
html += '<div class="widget-body" ><div class="widget-main" ><div class="row-fluid">';
html += '<div id="cart_toolbarList " class="drags"><div id="'+itemFlag+ droppedToolId + 'List_items" style="height:100px">';
html += '<ul class="item-list ui-sortable ' + droppedToolId + 'List'+ itemFlag + '" style="height:100%;border-style: dashed;border-width: 1px;border-color: silver;">';
html += '</ul></div></div></div></div></div></div></div>';
$("#" + mainDivId).draggable({
revertDuration : 0,
refreshPositions : true,
revert: true,
helper : 'clone'
});
$("#processFlowId").append(html);
}
请参考我的 Jsfiddle
问题
我需要拖动李并在我掉落的位置画画。现在它没有被绘制在我们放弃的位置。
有任何建议要做到这一点! 在此先感谢!
答案 0 :(得分:0)
为了获得放置位置,我们使用ui.position,它将相对于offset元素给出“top,left”。即,
var top = ui.position.top; // gives the top postion
var left = ui.position.left; // gives the left postion
现在,在style属性的帮助下,将这些x和y坐标附加到附加到div id“processFlowId”的小方框div中。如,
<div class="mouseHover" id="'+ mainDivId+ '"'+ 'style="width:200px;position:absolute; top: '+ top+ 'px; left: '+ left+ 'px;"'>
