项目管理工具DHTMLX Gantt灯箱元素配置教程：自定义三方持续时间控制

您需要向lightbox添加一个自定义Duration控件，以指定任务的开始日期和天数。

如何在jQuery的基础上添加一个自定义的Duration控件:

在页面中包含jQuery库的源文件:

<script src="https://code.jquery.com/jquery-3.5.1.min.js"></script><script src="https://code.jquery.com/ui/1.12.1/jquery-ui.min.js"></script><link  rel="stylesheet" type="text/css"    href="https://code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">

描述控制逻辑:

(function () {    function startDatepicker(node){        return $(node).find("input[name='start']");    }    function durationInput(node){        return $(node).find("input[name='duration']");    }    function endDateLabel(node){        return $(node).find("span.gantt-lb-datepicker-label");    }    var formatter = gantt.ext.formatters.durationFormatter({        enter: "day",        store: "day",        format: "auto"    });    gantt.form_blocks["datepicker_duration"] = {        render: function (sns) { //sns - the section's configuration object            return "<div class='gantt-lb-datepicker'>"+                "<label>Start:<input type='text' name='start'></label>"+                "<label>Duration: <input type='text' name='duration'></label>"+                "<span class='gantt-lb-datepicker-label'></span>"                "</div>";        },        set_value: function (node, value, task, section) {            //node - an html object related to the html defined above            //value - a value defined by the map_to property            //task - the task object            //section- the section's configuration object            startDatepicker(node).datepicker({                dateFormat: "yy-mm-dd",                onSelect: function (dateStr) {                    var endValue = durationInput(node).datepicker('getDate');                    var startValue = startDatepicker(node).datepicker('getDate');                    if(startValue && endValue){                        if(endValue.valueOf() <= startValue.valueOf()){                            durationInput(node).datepicker("setDate",                                gantt.calculateEndDate({                                    start_date: startValue, duration: 1, task:task                                })                            );                        }                    }                }            });            startDatepicker(node).datepicker("setDate", task.start_date);            durationInput(node).val(formatter.format(task.duration));            endDateLabel(node).text(                "Ends: " + gantt.templates.task_date(task.end_date)            );        },        get_value: function (node, task, section) {            if(task.start_date && task.end_date) {                var start = startDatepicker(node).datepicker('getDate');                var end = task.end_date;                var duration = formatter.parse(durationInput(node).val());                if(duration && !isNaN(Number(duration))){                    end = gantt.calculateEndDate({                        start_date: start, duration: duration, task:task                    });                }                task.start_date = start;                task.duration = duration;                task.end_date = end;            }            task.duration = gantt.calculateDuration(task);            return {                start_date: task.start_date,                end_date: task.end_date,                duration: task.duration            }        },        focus: function (node) {        }    }})();

将该控件作为类型为”datepicker_duration”的灯箱部分使用:

gantt.config.lightbox.sections = [  { name: "description", height: 70, map_to: "text", type: "textarea", focus: true },  { name: "time", height: 72, map_to: "auto", type: "datepicker_duration" }];
