How do I console.log a jQuery DOM Element in Chrome?
提问by Naftali aka Neal
I used to be able to do console.log(somejQueryObj);
and it logged in an array all of the DOM elements that are in the object that I could click and go to the inspector.
我曾经能够这样做,console.log(somejQueryObj);
并且它将对象中的所有 DOM 元素都记录在一个数组中,我可以单击并转到检查器。
Now it does something like this:
现在它做了这样的事情:
[prevObject: p.fn.p.init[1], context: , selector: ".next ()"]
[prevObject: p.fn.p.init[1], context: , selector: ".next()"]
which can confuse many people.
这会让很多人感到困惑。

Update:I made a jQuery plugin to bring back the old style logging: jquery.chromelog.
更新:我制作了一个 jQuery 插件来恢复旧样式的日志记录:jquery.chromelog。
You could create a little function to log all elements on one line:
您可以创建一个小函数来记录一行中的所有元素:
$.fn.log = function() {
console.log.apply(console, this);
return this;
};
Usage:
用法:
$("...").log();

要为每个元素执行此操作以便您可以将鼠标悬停在它上面,请尝试以下操作:
$("div").each(function(){console.log(this)})?

I have found a solutionthat would log them individually if need be (but it could clutter the log if it is BIG selector):
我找到了一个解决方案,可以在需要时单独记录它们(但如果它是 BIG 选择器,它可能会使日志混乱):

var log = function($selector) {
$selector.each(function() {
console.log(this);
});
};
log($('selector'))?;
