Try this

Try this way.

<pre><code>Date.prototype.addSeconds = function(seconds) {
 var copiedDate = new Date(this.getTime());
 return new Date(copiedDate.getTime() + seconds * 1000);
}
</code></pre>

Just call and assign <code>new Date().addSeconds(10)</code>

blocks|key|545286|text|javascript中的Date()对象实际上并不那么智能。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|545287|如果你只专注于添加秒数，它似乎可以很顺利地处理事情，但如果你尝试添加X个秒数，然后在同一个Date对象中添加X个分钟数和小时数，等等，那么你就会遇到麻烦。因此，我只是简单地退回到只使用setSeconds()方法并将我的数据转换为秒(这很好用)。|545288|如果有人能演示如何使用所有的set方法向全局Date()对象添加时间，并且最终的时间是正确的，我很想看到它，但我感觉在给定的Date()对象上一次只能使用一个set方法，混合使用它们会导致混乱。|545289|var+vTime+=+new+Date();

The <code>Date()</code> object in javascript is not that smart really.

If you just focus on adding seconds it seems to handle things smoothly but if you try to add X number of seconds then add X number of minute and hours, etc, to the same <code>Date</code> object you end up in trouble. So I simply fell back to only using the <code>setSeconds()</code> method and converting my data into seconds (which worked fine).

If anyone can demonstrate adding time to a global <code>Date()</code> object using all the set methods and have the final time come out correctly I would like to see it but I get the sense that one set method is to be used at a time on a given <code>Date()</code> object and mixing them leads to a mess.

<pre><code>var vTime = new Date();

var iSecondsToAdd = ( iSeconds + (iMinutes * 60) + (iHours * 3600) + (iDays * 86400) );

vTime.setSeconds(iSecondsToAdd);
</code></pre>

Few years ago i've wrote a 'generic' date function:
<pre><code>function addToDate({time_unit, operator, offset_value }) {
 const date = new Date();
 operator = operator == &quot;after&quot; ? &quot;+&quot; : &quot;-&quot;;
 switch (time_unit) {
 case &quot;seconds&quot;:
 date.setSeconds(eval(`${date.getSeconds()} ${operator} ${offset_value}`));
 break;

 case &quot;hours&quot;:
 date.setHours(eval(`${date.getHours()} ${operator} ${offset_value}`));
 break;

 case &quot;minutes&quot;:
 date.setMinutes(eval(`${date.getMinutes()} ${operator} ${offset_value}`));

 break;
 case &quot;days&quot;:
 date.setDate(eval(`${date.getDate()} ${operator} ${offset_value}`));
 break;

 case &quot;months&quot;:
 date.setMonth(eval(`${date.getMonth()} ${operator} ${offset_value}`));

 break;
 case &quot;years&quot;:
 date.setFullYear(eval(`${date.getFullYear()} ${operator} ${offset_value}`));
 break;
 default:
 break;
 }

 return date;
}

const new_date = addToDate({time_unit:'seconds','operator':'after','offset_value':10});

console.log(new_date.toISOString());

How can I add 10 seconds to a JavaScript date object?

Something like this:

<pre><code>var timeObject = new Date() 
var seconds = timeObject.getSeconds() + 10;
timeObject = timeObject + seconds;
</code></pre>

Add 10 seconds to a Date

如何向JavaScript date对象添加10秒？如下所示：var timeObject = new Date()     var seconds = timeObject.getSeconds() + 10;timeObject = timeObject + seconds;
