随着IT信息技术的发展，工业化和信息化结合的场景越来越多。下面是某公司通过信息化系统动态维护设备开发的案例。
整体效果
设备管理
可以从左侧把需要的设备拖拽到右边的画布，双击可以维护设备的信息以及点位。2个设备之间可以添加连线。

$("#flowBox").droppable({
scope: 'ss',
drop: function (event, ui) {
var $chart = $(ui.draggable[0]);
var node = {};
node.id = "node" + Math.random().toString(36).substr(3, 10);
node.name = $chart.attr("data-name");
node.data_id = $chart.attr("id");
node.data_code = $chart.attr("data-code");
node.data_type = $chart.attr("data-type");
node.type = 'chart';
node.groupId = null;
node.width = 150;
node.height = 130;
node.left = miniview_position.left * miniview_percent + (ui.position.left - 100);
node.top = miniview_position.top * miniview_percent + (ui.position.top - 50);
node.EndpointList = getEndpointList(node);
addNode(node);
}
})
function drawNode(node) {
if(node.type == 'chart'){
var nodeDiv = ['<div data_name="'+node.name+'" onmouseup="changeNodeSite(this)" onclick="onclickNode(this)" ondblclick="ondblclickNode(this)" id="' + node.id + '" class="nodeBox" style="left:' + node.left + 'px;top:' + node.top + 'px;width:' + node.width + 'px;height:' + node.height + 'px">',
'<div class="nodeBox-img ' + node.data_type + '"></div>',
'<div class="nodeBox-text" >' + node.name + '</div>',
'</div>'].join('');
$("#flowBox").append(nodeDiv);
// 拖拽改变大小
$("#"+node.id).resizable({
autoHide: true ,
minHeight: 50,
minWidth:50,
aspectRatio:15/13,
containment: "parent",
resize: function (event, ui) {
changeNodeSize(node.id,ui.size.width,ui.size.height)
//拖拽时点位跟着变动
jsPlumb.repaint(ui.helper);
jsPlumb.repaintEverything();
}
})
jsPlumb.draggable(node.id);
if(node.groupId !=null){
var el = eval（'(' + node.id + ')');
var groupNode = dataNodeList.filter(function (itemNode) {
return itemNode.id == node.groupId;
})[0];
$("#"+node.id).css('left',(groupNode.left + node.left)+"px");
$("#"+node.id).css('top',(groupNode.top + node.top)+"px");
jsPlumb.addToGroup(node.groupId, el);
}
}
if(node.EndpointList !=null && node.EndpointList.length >0){
for (var i = 0; i < node.EndpointList.length; i++) {
jsPlumb.addEndpoint(node.id, {uuid:node.EndpointList[i].id,anchors:locationToAnchors(node.EndpointList[i].location,node)}, GetEndpointOptions(node.EndpointList[i]));
}
}
}设备组管理
多个设备可以拉进一个设备组中一起管理，组㐓展开折叠。
jsPlumb通过事件控制组元素的新增和删除
//添加到组
jsPlumb.bind("group:addMember",function(evt) {
var nodeId = evt.el.id;
var groupId = evt.group.id;
var pos = evt.pos;
for (var i = 0; i < dataNodeList.length; i++) {
if (dataNodeList[i].id == nodeId) {
dataNodeList[i].groupId = groupId;
dataNodeList[i].left = pos.left;
dataNodeList[i].top = pos.top;
break;
}
}
});
//从组中删除
jsPlumb.bind("group:removeMember",function(evt) {
console.log(1)
var nodeId = evt.el.id;
var groupId = evt.group.id;
var pos = evt.pos;
for (var i = 0; i < dataNodeList.length; i++) {
if (dataNodeList[i].id == nodeId) {
dataNodeList[i].groupId = null;
dataNodeList[i].left = pos.left;
dataNodeList[i].top = pos.top;
break;
}
}
});
其他功能
其中还有放大缩小整个画布、导入导出，返回上一步等其他功能。下面附上所有的JavaScript代码，感兴趣的同学可以学习参考一下。
