使用JavaScript对象的console.log的奇怪行为 [英] Weird behaviour of console.log with JavaScript object
问题描述
当我使用HTML为每个循环打印对象时,我只得到对象的一半内容但是当我使用 console.log
打印时按下那个小三角形我当我在悬停时显示完整对象和 i ,它表示刚刚评估了值,如下图所示,
when I print object in HTML using for each loop I'm getting only half contents of the object but when I print using console.log
and press that little triangle I'm getting full object and i is shown near that object when I hover that it says value was evaluated just now as shown in below image,
当我在html中打印相同的对象时,它看起来像这样,
When i print same object in html it looks like this,
7.33--AAYUSH MOHTA
7.08--AAYUSH PRAKASH
7.83--ABHINAV KUMAR TIWARI
实际上对象包含总共5个元素,如上图所示,
代码用于打印对象html,
Actually object contains total 5 elements as shown in above image, Code for printing object html,
for (var key in obj){
$("p").append(key+"--"+obj[key][0]+"<br>");
}
推荐答案
通过<$ c检查对象$ c> console.log 以异步
方式发生。
对象的引用同步传递给控制台,但在扩展之前它不会显示属性。如果在控制台中检查对象之前修改了对象,则显示的数据将具有更新的值。 Chrome控制台在一个框中显示一点 i
,其中表示刚刚评估了以下值
The reference to the object is passed synchronously to console but it doesn't display the properties till its expanded . If the object has been modified before examining it in the console, the data shown will have the updated values. Chrome console shows a little i
in a box which which says value below was evaluated just now
为了打印完全在控制台中的对象,你可以字符串化并记录它像
In order to print the object completely in console, you can stringify and log it like
console.log(JSON.stringify(obj));
