There is an easy way...

<pre><code>$(arr1).not(arr2).length === 0 &amp;&amp; $(arr2).not(arr1).length === 0
</code></pre>

If the above returns true, both the arrays are same even if the elements are in different order. 

NOTE: This works only for jquery versions &lt; 3.0.0 when using JSON objects

blocks|key|1401691|text|我的方法完全不同--我使用JSON.stringify将两个集合拉平，并使用普通的字符串比较来检查是否相等。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1401692|也就是说。|1401693|var+arr1+=+[
+++++++++++++{Col:+'a',+Val:+1},+
+++++++++++++{Col:+'b',+Val:+2},+

}else{
++++alert('Collections+are+not+equal');
}|code-block|syntax|javascript|1401694|注意:请注意，他的方法假设两个集合都以类似的方式排序，如果不是这样，它将给你一个错误的结果！|1401695|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|N|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|O|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|P|8|@]|9|@]|A|$]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

My approach was quite different - I flattened out both collections using JSON.stringify and used a normal string compare to check for equality.

I.e.

<pre><code>var arr1 = [
 {Col: 'a', Val: 1}, 
 {Col: 'b', Val: 2}, 
 {Col: 'c', Val: 3}
 ];

var arr2 = [
 {Col: 'x', Val: 24}, 
 {Col: 'y', Val: 25}, 
 {Col: 'z', Val: 26}
 ];

if(JSON.stringify(arr1) == JSON.stringify(arr2)){
 alert('Collections are equal');
}else{
 alert('Collections are not equal');
}
</code></pre>

NB: Please note that his method assumes that both Collections are sorted in a similar fashion, if not, it would give you a false result!

I found this discussion because I needed a way to deep compare arrays and objects. Using the examples here, I came up with the following (broken up into 3 methods for clarity):

<pre><code>jQuery.extend({
 compare : function (a,b) {
 var obj_str = '[object Object]',
 arr_str = '[object Array]',
 a_type = Object.prototype.toString.apply(a),
 b_type = Object.prototype.toString.apply(b);

 if ( a_type !== b_type) { return false; }
 else if (a_type === obj_str) {
 return $.compareObject(a,b);
 }
 else if (a_type === arr_str) {
 return $.compareArray(a,b);
 }
 return (a === b);
 }
});

jQuery.extend({
 compareArray: function (arrayA, arrayB) {
 var a,b,i,a_type,b_type;
 // References to each other?
 if (arrayA === arrayB) { return true;}

 if (arrayA.length != arrayB.length) { return false; }
 // sort modifies original array
 // (which are passed by reference to our method!)
 // so clone the arrays before sorting
 a = jQuery.extend(true, [], arrayA);
 b = jQuery.extend(true, [], arrayB);
 a.sort(); 
 b.sort();
 for (i = 0, l = a.length; i &lt; l; i+=1) {
 a_type = Object.prototype.toString.apply(a[i]);
 b_type = Object.prototype.toString.apply(b[i]);

 if (a_type !== b_type) {
 return false;
 }

 if ($.compare(a[i],b[i]) === false) {
 return false;
 }
 }
 return true;
 }
});

jQuery.extend({
 compareObject : function(objA,objB) {

 var i,a_type,b_type;

 // Compare if they are references to each other 
 if (objA === objB) { return true;}

 if (Object.keys(objA).length !== Object.keys(objB).length) { return false;}
 for (i in objA) {
 if (objA.hasOwnProperty(i)) {
 if (typeof objB[i] === 'undefined') {
 return false;
 }
 else {
 a_type = Object.prototype.toString.apply(objA[i]);
 b_type = Object.prototype.toString.apply(objB[i]);

 if (a_type !== b_type) {
 return false; 
 }
 }
 }
 if ($.compare(objA[i],objB[i]) === false){
 return false;
 }
 }
 return true;
 }
});
</code></pre>

Testing

<pre><code>var a={a : {a : 1, b: 2}},
 b={a : {a : 1, b: 2}},
 c={a : {a : 1, b: 3}},

console.debug('a and b = ' + $.compare(a,b)); // a and b = true

blocks|key|1401396|text|我不认为有一个很好的"jQuery“方法可以做到这一点，但是如果你需要效率，可以通过某个键(唯一的对象字段之一)映射其中一个数组，然后通过循环遍历另一个数组并与您刚刚构建的映射或关联数组进行比较来进行比较。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1401397|如果效率不是问题，只需将A中的每个对象与B中的每个对象进行比较。只要%7CA%7C和%7CB%7C很小，就应该没问题。|1401398|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

I don't think there's a good "jQuery " way to do this, but if you need efficiency, map one of the arrays by a certain key (one of the unique object fields), and then do comparison by looping through the other array and comparing against the map, or associative array, you just built.

If efficiency is not an issue, just compare every object in A to every object in B. As long as |A| and |B| are small, you should be okay.

<pre><code>var arr = [11, "String #1", 14, "String #2"];
var arr_true = ["String #1", 14, "String #2", 11]; // contents are the same as arr
var arr_false = ["String #1", 14, "String #2", 16]; // contents differ

function test(arr_1, arr_2) {
 var equal = arr_1.length == arr_2.length; // if array sizes mismatches, then we assume, that they are not equal
 if (equal) {
 $.each(arr_1, function (foo, val) {
 if (!equal) return false;
 if ($.inArray(val, arr_2) == -1) {
 equal = false;

I also found this when looking to do some array comparisons with jQuery. In my case I had strings which I knew to be arrays:

<pre><code>var needle = 'apple orange';
var haystack = 'kiwi orange banana apple plum';
</code></pre>

But I cared if it was a complete match or only a partial match, so I used something like the following, based off of Sudhakar R's answer:

<pre><code>function compareStrings( needle, haystack ){
 var needleArr = needle.split(" "),
 haystackArr = haystack.split(" "),
 compare = $(haystackArr).not(needleArr).get().length;

 if( compare == 0 ){
 return 'all';
 } else if ( compare == haystackArr.length ) {
 return 'none';
 } else {
 return 'partial';
 }
}

Try this 

<pre><code>function check(c,d){
 var a = c, b = d,flg = 0;
 if(a.length == b.length) 
 { 
 for(var i=0;i&lt;a.length;i++) 
 a[i] != b[i] ? flg++ : 0; 
 } 
 else 
 { 
 flg = 1; 
 } 
 return flg = 0;
}
</code></pre>

I have two arrays of JavaScript Objects that I'd like to compare to see if they are the same. The objects may not (and most likely will not) be in the same order in each array. Each array shouldn't have any more than 10 objects. I thought jQuery might have an elegant solution to this problem, but I wasn't able to find much online.

I know that a brute nested <code>$.each(array, function(){})</code> solution could work, but is there any built in function that I'm not aware of?

Thanks.

Using jQuery to compare two arrays of Javascript objects

jQuery

JSON

我有两个JavaScript对象数组，我想对它们进行比较，看看它们是否相同。对象在每个数组中的顺序可能不同(并且很可能不会)。每个数组不应该有超过10个对象。我以为jQuery可能有一个很好的解决方案来解决这个问题，但我在网上找不到太多。我知道粗暴的嵌套$.each(array, function(){})解决方案可以工作，但是有没有我不知道的内置函数呢？谢谢。
