activiti自定义流程之整合(二):使用angular js整合ueditor创建表单

注:整体环境搭建:activiti自定义流程之整合(一):整体环境配置

基础环境搭建完毕,接下来就该正式着手代码编写了,在说代码之前,我觉得有必要先说明一下activit自定义流程的操作。

抛开自定义的表单不谈,通过之前的了解,我们知道一个新的流程开始,是在启动流程实例(processIntence)的时候,而流程实例依赖于流程定义(processDefinition),流程定义又依赖于流程模型(model)。

我们用到的自定义表单需要在创建模型,画模型图的时候就指定表单的名称formKey,需要保证这个formKey和我们创建的表单名称一致。

表单并不在创建模型的时候使用,而是在部署的时候用到,因此只要是在部署流程定义之前创建自定义表单,那么无论是先创建模型还是先创建表单,只要名称一致就行。

那么我这里就先创建表单,因为我觉得这样的话,在创建模型时可以预览,更能保证创建模型的正确性(虽然模型也可以修改);

与之前的自定义表单稍有不同的是,在这个整合的例子中,我用的是angularjs,同时预览时也用到了jquery中的dialog对话框的功能,也就需要比之前导入更多前端的js,他们如下图所示。

需要注意的是,dialog的样式在jquery-ui.js中控制,这个也是网上下载的。

前端首页index.html代码如下,因为angular js为单页面应用,因此实际上只有一个html声明,所有的js以及css文件也都需要在index.html中一开始就导入进来:

<!DOCTYPE html><html ng-app="activitiApp"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><link href="./activi_css/activi.css" rel="stylesheet"/> <script type="text/javascript">var _root='http://form/index.php?s=/',_controller = 'index';</script><script src="./angular-1.4.0-rc.2/angular.js"></script><script src='./angular-1.4.0-rc.2/angular-ui-router.js'></script><script src='./activi_js/app.js'></script><script src='./activi_js/createCtr.js'></script><script src='./activi_js/modelCtr.js'></script><script src='./activi_js/processCtr.js'></script><script src='./activi_js/taskCtr.js'></script><script src='./activi_js/findFirstTaskCtr.js'></script><script src='./activi_js/loginCtr.js'></script><script src='./activi_js/hisTaskCtr.js'></script><script src='./activi_js/completeTaskCtr.js'></script><script src='./activi_js/completeTaskTo1Ctr.js'></script><script src="./my_js/updateFormCtr.js"></script><script src="./my_js/formListCtr.js"></script><!-- 导入form相关的js --><!-- <meta name="viewport" content="width=device-width, initial-scale=1.0"><meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"><link href="form_css/bootstrap/css/bootstrap.css?" rel="stylesheet" type="text/css" /><link href="form_css/site.css?" rel="stylesheet" type="text/css" />--><link href="form_css/jquery-ui.css" rel="stylesheet" type="text/css" /><link href="my_css/a.css" rel="stylesheet" type="text/css" /><script type="text/javascript">var _root='http://form/index.php?s=/',_controller = 'index';</script> <script src="form_js/jquery-1.7.2.min.js?"></script><script src="form_js/common.js"></script><script src="form_js/jquery-ui.js"></script><script src="form_js/jquery.form.js"></script><script src="form_js/ajax.js"></script><script src="form_js/common/plugins/validate/jquery.validate.pack.js"></script><script src="form_js/jquery.datetimepicker.js"></script><script src="form_js/ueditor/ueditor.config.js?"></script><script src="form_js/ueditor/ueditor.all.js?"> </script><script src="form_js/ueditor/lang/zh-cn/zh-cn.js?"></script><script src="form_js/ueditor/formdesign/leipi.formdesign.v4.js?"></script><!-- 导入form相关的js --></head><body style="width:100%;height:400px;margin:0;background-color:#fff"><div style="height:70px;width:100%;border:1px solid #ccf"><img id="rdiv" src="./images/activiti.png" style="width:30%;height:98%"/><a href="script:;" ng-show="userName!=undefined" style="margin-right:10px;float:right;margin-top:25px;" ng-click="logOut();">[退出登陆]</a><font ng-show="userName!=undefined" style="margin-right:10px;float:right;margin-top:25px;">当前登陆用户:{{userName}}</font></div><div style="width:100%;position: absolute;height:auto"><div style="height:630px;width:12%;font-size:36px;position:relative;float:left;border:1px solid #ccf" ng-show="userName!=undefined"><table style="width:100%;text-align:center;margin-top:0px" cellSpacing="5px" cellPadding="0px"><tr><td style="background-color:#aac;"><a href="#/create">创建模型</a></td></tr><tr><td style="background-color:#acd;"> <a href="#/modelList">模型列表</a></td></tr><tr><td style="background-color:#aac;"><a href="#/processList">流程列表</a></td></tr><tr><td style="background-color:#acd;"><a href="#/findFirstTask">我的申请</a></td></tr><tr><td style="background-color:#aac;"><a href="#/taskList">我的任务</a></td></tr><tr><td style="background-color:#acd;"><a href="#/hisTask">历史任务</a></td></tr><tr><td style="background-color:#aac;"><a href="#/createForm">创建表单</a></td></tr><tr><td style="background-color:#acd;"><a href="#/formList">表单列表</a></td></tr></table></div><div ui-view="view" ></div></div></body></html>

Angular js 控制路由跳转app.js代码:

var app=angular.module('activitiApp',['ui.router']); app.run(function($rootScope) {$rootScope.logOut=function(){$http.post("./loginOut.do").success(function(loginOutResult){$rootScope.userName=undefined;$location.path("/login");});}});app.config(function($stateProvider,$urlRouterProvider){ $stateProvider .state('createForm', { url: "/createForm", views: { 'view': { templateUrl: 'my_views/updateForm.html', controller: 'updateFormCtr' } } }); });

新增form表单的页面updateForm.html代码如下,要注意的是,这个页面也是有ueditor插件中的index.html改变过来的:

<div id="formDiv" style="margin-top:20px;margin-left:50px;height:550px;width:70%;font-size:18px;position:relative;float:left;"><div class="container"><form method="post" id="saveform" name="saveform" action="/index.php?s=/index/parse.html"><input type="hidden" name="fields" id="fields" value="0"><div style="width:98%;height:500px;margin-top:20px;border:3px solid grey"><p style="margin-top:10px;font-size:30px" >表单名称:<input type="text" id="formType"></input></p><hr style="height:5px;border:none;border-top:5px ridge green;"/><p style="margin-top:10px;font-size:30px" >表单设计:</p><div ><p style="left:30px"><button type="button" ng-click="leipiFormDesign.exec('text');" class="btn btn-info">文本框</button><button type="button" ng-click="leipiFormDesign.exec('textarea');" class="btn btn-info">多行文本</button><button type="button" ng-click="leipiFormDesign.exec('select');" class="btn btn-info">下拉菜单</button><button type="button" ng-click="leipiFormDesign.exec('radios');" class="btn btn-info">单选框</button><button type="button" ng-click="leipiFormDesign.exec('checkboxs');" class="btn btn-info">复选框</button> <button type="button" ng-click="leipiFormDesign.exec('listctrl');" class="btn btn-info">列表控件</button><button type="button" ng-click="leipiFormDesign.findForm();" class="btn btn-info">form</button></p></div><!-- afsddddddddd --><div ><script id="myFormDesign" type="text/plain" style="width:99.8%;"></script></div> </div><!-- afsddddddddd --><div class="row"></div><!--end row--></form></div><!--end container--></div>

对应的js代码updateFormCtr.js,这里尤其需要注意的是leipiFormDesign.exec这个方法原本是ueditor插件中的,如果不做修改直接拿过来的话,在上便的页面中是无法调用的,angularjs需要注意作用域的问题,因此在对应的js中需要改成$scope. leipiFormDesign;除此之外,在保存和预览时基本没有什么变化,dialog对话框也是在后续流程中使用到:

angular.module('activitiApp') .controller('updateFormCtr', ['$rootScope','$scope','$http','$location','$state', function($rootScope,$scope,$http,$location,$state){ $http.post("createFlush.do").success(function(result){if(result.isLogin==="yes"){$rootScope.userName=result.userName;}else{$location.path("/login");}});//预览UE.registerUI('button_preview',function(editor,uiName){if(!this.options.toolleipi){return false;}//注册按钮执行时的command命令,使用命令默认就会带有回退操作editor.registerCommand(uiName,{execCommand:function(){try {$scope.leipiFormDesign.fnReview();} catch ( e ) {alert('leipiFormDesign.fnReview 预览异常');}}});//创建一个buttonvar btn = new UE.ui.Button({//按钮的名字name:uiName,//提示title:"预览",//需要添加的额外样式,指定icon图标,这里默认使用一个重复的iconcssRules :'background-position: -420px -19px;',//点击时执行的命令onclick:function () {//这里可以不用执行命令,做你自己的操作也可editor.execCommand(uiName);}});//因为你是添加button,所以需要返回这个buttonreturn btn;});//保存UE.registerUI('button_save',function(editor,uiName){if(!this.options.toolleipi){return false;}//注册按钮执行时的command命令,使用命令默认就会带有回退操作editor.registerCommand(uiName,{execCommand:function(){try {$scope.leipiFormDesign.fnCheckForm('save');} catch ( e ) {alert('leipiFormDesign.fnCheckForm("save") 保存异常');}}});//创建一个buttonvar btn = new UE.ui.Button({//按钮的名字name:uiName,//提示title:"保存表单",//需要添加的额外样式,指定icon图标,这里默认使用一个重复的iconcssRules :'background-position: -481px -20px;',//点击时执行的命令onclick:function () {//这里可以不用执行命令,做你自己的操作也可editor.execCommand(uiName);}});//因为你是添加button,所以需要返回这个buttonreturn btn;});//整合设计器var leipiEditor = UE.getEditor('myFormDesign',{toolleipi:true,//是否显示,设计器的 toolbarstextarea: 'design_content', //这里可以选择自己需要的工具按钮名称,此处仅选择如下五个toolbars:[[]],//关闭字数统计wordCount:false,//关闭elementPathelementPathEnabled:false,//默认的编辑区域高度initialFrameHeight:260//,iframeCssUrl:"css/bootstrap/css/bootstrap.css" //引入自身 css使编辑器兼容你网站css//更多其他参数,请参考ueditor.config.js中的配置项});$scope.leipiFormDesign = {findForm : function(){window.location.href="my_views/formList.html";},/*执行控件*/exec : function (method) {leipiEditor.execCommand(method);},/*Javascript 解析表单template 表单设计器里的Html内容fields 字段总数*/parse_form:function(template,fields){//正则 radios|checkboxs|select 匹配的边界 |--| 因为当使用 {} 时js报错var preg = /(\|-<span(((?!<span).)*leipiplugins=\"(radios|checkboxs|select)\".*?)>(.*?)<\/span>-\||<(img|input|textarea|select).*?(<\/select>|<\/textarea>|\/>))/gi,preg_attr =/(\w+)=\"(.?|.+?)\"/gi,preg_group =/<input.*?\/>/gi;if(!fields) fields = 0;var template_parse = template,template_data = new Array(),add_fields=new Object(),checkboxs=0;var pno = 0;template.replace(preg, function(plugin,p1,p2,p3,p4,p5,p6){var parse_attr = new Array(),attr_arr_all = new Object(),name = '', select_dot = '' , is_new=false;var p0 = plugin;var tag = p6 ? p6 : p4;//alert(tag + " \n- t1 - "+p1 +" \n-2- " +p2+" \n-3- " +p3+" \n-4- " +p4+" \n-5- " +p5+" \n-6- " +p6);if(tag == 'radios' || tag == 'checkboxs'){plugin = p2;}else if(tag == 'select'){plugin = plugin.replace('|-','');plugin = plugin.replace('-|','');}plugin.replace(preg_attr, function(str0,attr,val) {if(attr=='name'){if(val=='leipiNewField'){is_new=true;fields++;val = 'data_'+fields;}name = val;}if(tag=='select' && attr=='value'){if(!attr_arr_all[attr]) attr_arr_all[attr] = '';attr_arr_all[attr] += select_dot + val;select_dot = ',';}else{attr_arr_all[attr] = val;}var oField = new Object();oField[attr] = val;parse_attr.push(oField);}) /*alert(JSON.stringify(parse_attr));return;*/if(tag =='checkboxs') /*复选组 多个字段 */{plugin = p0;plugin = plugin.replace('|-','');plugin = plugin.replace('-|','');var name = 'checkboxs_'+checkboxs;attr_arr_all['parse_name'] = name;attr_arr_all['name'] = '';attr_arr_all['value'] = '';attr_arr_all['content'] = '<span leipiplugins="checkboxs" title="'+attr_arr_all['title']+'">';var dot_name ='', dot_value = '';p5.replace(preg_group, function(parse_group) {var is_new=false,option = new Object();parse_group.replace(preg_attr, function(str0,k,val) {if(k=='name'){if(val=='leipiNewField'){is_new=true;fields++;val = 'data_'+fields;}attr_arr_all['name'] += dot_name + val;dot_name = ',';}else if(k=='value'){attr_arr_all['value'] += dot_value + val;dot_value = ',';}option[k] = val; });if(!attr_arr_all['options']) attr_arr_all['options'] = new Array();attr_arr_all['options'].push(option);//if(!option['checked']) option['checked'] = '';var checked = option['checked'] !=undefined ?

相对于前台而言,后台在这里就没有什么变化了,可以参考之前的自定义表单,代码便不再罗列。
