本文给大家讲解DHTMLX Gantt如何对控件选择性控制,欢迎大家下载最新版试用体验。
下拉列表框如下所示:
gantt.config.lightbox.sections = [ {name:"description", height:38, map_to:"text", type:"textarea", focus:true}, {name:"priority", height:22, map_to:"priority", type:"select", options: [ {key:1, label: "High"}, {key:2, label: "Normal"}, {key:3, label: "Low"} ]}, {name:"time", height:72, type:"duration", map_to:"auto"}];gantt.locale.labels.section_priority = "Priority";
1、初始化
要将选择控件添加到灯箱,请执行以下步骤:
1、在灯箱配置中添加一个部分:
var opts = [ {key:1, label: "High"}, {key:2, label: "Normal"}, {key:3, label: "Low"} ];gantt.config.lightbox.sections = [ {name:"description", height:38, map_to:"text", type:"textarea",focus:true}, {name:"priority", height:22, map_to:"priority",type:"select",options:opts}, {name:"time", height:72, type:"duration", map_to:"auto"}];
2、给部分设置标签:
gantt.locale.labels.section_priority = "Priority";
2、属性
以下属性最重要且通常用的时间控属性:
以下属性最重要且通常为选择控件设置:
name – (字符串) 部分名称
高度- (数字)截面高度
map_to – ( string ) 将被映射到该部分的数据属性的名称
type – ( string )部分控件的类型
focus – ( boolean ) 如果设置为true,该部分将专注于打开灯箱
options – ( array ) 对象数组。定义控件的选择选项(用于选择、复选框 和单选 控件)。数组中的每个对象都指定一个选项并具有以下属性:
key – ( string ) 选项 id。此属性与任务数据属性进行比较以将选项分配给任务
label – ( string ) 选项标签
default_value – ( any ) 该部分控件的默认值。仅在输入值不足时应用
onchange – ( function ) 为该部分的控件指定“onChange”事件处理函数
3、用数据填充控件
通常,要为选择控件设置值,请使用options参数:
gantt.config.lightbox.sections = [ { name:"priority",height:22, map_to:"priority",type:"select", options: [ {key:1, label: "High"}, {key:2, label: "Normal"}, {key:3, label: "Low"} ]} ];
options参数中的项目有 2 个强制属性:
- key – 选项 ID
- label – 选项标签
4、使用来自服务器的数据填充
要从服务器填充控件,请将options选项设置为serverList方法返回的值:
gantt.config.lightbox.sections = [ {name:"description", ...}, { name:"priority",map_to:"priority",type:"select", options:gantt.serverList("priority")}, {name:"category", map_to:"category", type:"select", options:gantt.serverList("category")}, {name:"time", ...}];gantt.init("gantt_here");gantt.load("/data");
/data url的输出如下:
{ "tasks":[ {"id":1,"text":"Project #2","start_date":"01-04-2020","duration":18,"parent":0}, {"id":2,"text":"Task #1","start_date":"02-04-2020","duration":8,"parent":1}, {"id":3,"text":"Task #2","start_date":"11-04-2020","duration":8,"parent":1} ], "links":[ {"id":1,"source":1,"target":2,"type":"1"}, {"id":2,"source":2,"target":3,"type":"0"} ], "collections": { "priority":[ {"value":"1","label":"Low"}, {"value":"2","label":"Medium"}, {"value":"3","label":"High"} ], "category":[ {"value":"1","label":"Simple"}, {"value":"2","label":"Complex"}, {"value":"3","label":"Unknown"} ] }}
通过 dhtmlxConnector 加载选项,以下是dhtmlxConnector初始化的示例:
//data.php<hp include('connector-php/codebase/gantt_connector.php'); $res = new PDO("mysql:host=localhost;dbname=gantt", "root", ""); $list = new OptionsConnector($res); $list->render_table("priorities","id","id(value),name(label)"); $gantt = new JSONGanttConnector($res); $gantt->set_options("priority", $list); $gantt->render_links("gantt_links","id","source_task(source), target_task(target),type"); $gantt->render_table("gantt_tasks","id","start_date,duration,text,progress, sortorder,parent");gt;
