The problem that layui time control cannot be used normally after it is cleared

Solve the problem that the layui time control cannot be used normally after it is cleared, as well as the selection of time range.

There are two solutions:

Method 1 (layui 1.x):

html code:

<div class="layui-inline">
<div class="layui-input-inline">
<input type="text" name="start_time" class="layui-input" id="start_time"
placeholder="开始时间(修改时间)">
</div>
</div>
<div class="layui-inline">
<div class="layui-input-inline">
<input type="text" name="end_time" class="layui-input" id="end_time"
placeholder="结束时间(修改时间)">
</div>
</div>

Copy after login

js code:

var start = {
istime: true,
format: &#39;YYYY-MM-DD hh:mm:ss&#39;,
max: &#39;2099-06-16 23:59:59&#39;,
istoday: true,
choose: function (datas) {
end.min = datas; //开始日选好后，重置结束日的最小日期
}
};
var end = {
istime: true,
format: &#39;YYYY-MM-DD hh:mm:ss&#39;,
max: &#39;2099-06-16 23:59:59&#39;,
istoday: true,
choose: function (datas) {
start.max = datas; //结束日选好后，重置开始日的最大日期
}
};
document.getElementById(&#39;start_time&#39;).onclick = function () {
start.elem = this;
laydate(start);
};
document.getElementById(&#39;end_time&#39;).onclick = function () {
end.elem = this;
laydate(end);
};

Method 2 (layui 2.x):

html code

<div class="layui-inline">
<div class="layui-input-inline">
<input type="text" name="start_time" class="layui-input" id="start_time"
placeholder="开始时间(修改时间)">
</div>
</div>
<div class="layui-inline">
<div class="layui-input-inline">
<input type="text" name="end_time" class="layui-input" id="end_time"
placeholder="结束时间(修改时间)">
</div>
</div>

Copy after login

js code

layui.use([ &#39;laydate&#39;], function(){
var $ = layui.$;
var laydate = layui.laydate;
var nowTime = new Date().valueOf();
var max = null;
var start = laydate.render({
elem: &#39;#start_time&#39;,
type: &#39;datetime&#39;,
max: nowTime,
btns: [&#39;clear&#39;, &#39;confirm&#39;],
done: function(value, date){
endMax = end.config.max;
end.config.min = date;
end.config.min.month = date.month -1;
}
});
var end = laydate.render({
elem: &#39;#end_time&#39;,
type: &#39;datetime&#39;,
max: nowTime,
done: function(value, date){
if($.trim(value) == &#39;&#39;){
var curDate = new Date();
date = {&#39;date&#39;: curDate.getDate(), &#39;month&#39;: curDate.getMonth()+1, &#39;year&#39;: curDate.getFullYear()};
}
start.config.max = date;
start.config.max.month = date.month -1;
}
});

Dynamic limit the end time based on the start time Knowledge point

type: &#39;datetime&#39;, 是带时分秒的 date 是不带时分秒的

layui.use(&#39;laydate&#39;, function(){
   /* lay(&#39;.layui-input&#39;).each(function(){
  laydate.render({
    elem: this
    ,trigger: &#39;click&#39;
    ,change: function(value, date, endDate){
    console.log(value); //得到日期生成的值，如：2017-08-18
    console.log(date); //得到日期时间对象：{year: 2017, month: 8, date: 18, hours: 0, minutes: 0, seconds: 0}
    console.log(endDate); //得结束的日期时间对象，开启范围选择（range: true）才会返回。对象成员同上。
    }
  });
});  */
var $ = layui.$;
    var laydate = layui.laydate;
   var nowTime = new Date().valueOf();
    var max = null;
       var start = laydate.render({
        elem: &#39;#start_time&#39;,
        type: &#39;datetime&#39;,
        btns: [&#39;clear&#39;, &#39;confirm&#39;],
        done: function(value, date){
            endMax = end.config.max;
            end.config.min = date;
            end.config.min.month = date.month -1;
        },
        change: function(value, date, endDate){
        var timestamp2 = Date.parse(new Date(value));
timestamp2 = timestamp2 / 1000;
            end.config.min = timestamp2;
            end.config.min.month = date.month -1;
    }
    });
    var end = laydate.render({
        elem: &#39;#end_time&#39;,
        type: &#39;date&#39;,
        done: function(value, date){
        console.log(" ======  "+date);
            if($.trim(value) == &#39;&#39;){
                var curDate = new Date();
                date = {&#39;date&#39;: curDate.getDate(), &#39;month&#39;: curDate.getMonth()+1, &#39;year&#39;: curDate.getFullYear()};
            }
            start.config.max = date;
            start.config.max.month = date.month -1;
        }
    });
});

With the above code, it is possible to dynamically change the maximum value of the start time and the minimum value of the end time. Let’s talk about the pitfalls that are easy to encounter:

Pit 1: laydate.render cannot be rendered repeatedly. When an elem corresponding to laydate.render has been rendered once, we cannot modify the max by rendering it again. value and min value.

Pitfall 2: startDate.config.max and endDate.config.min are an object, not a string. I saw a person irresponsibly saying this on the Internet, endDate.config.min "2017-01-01"; He said it could be set, but I actually believed him and fell into the trap for a long time. What we actually get here is an object, which is different from min and max when we render. Directly assigning a string value will definitely have no effect.

Pit 3: Although the format of dates is the same as the format of endDate.config.min, but if you directly set endDate.config.min=dates, you will find that the result is not what you want, because although the data in dates is The date you selected, but the value of month set in endDate.config.min is one month greater than the value of month you entered. Therefore, if the start date you selected is November 13th, the value is directly assigned to endDate.config. After .min, you will find that the minimum date of the end date becomes December 13, so we need to reduce the month value in dates by one and then assign it to endDate.config.min.
