取消拆分两个数组Javascript

取消拆分两个数组是指将两个已拆分的数组重新合并为一个数组。在JavaScript中,可以使用concat()方法来实现这个操作。

concat()方法是JavaScript数组对象的一个方法,用于合并两个或多个数组,并返回一个新的数组。它不会改变原始数组,而是返回一个新的数组。

以下是使用concat()方法取消拆分两个数组的示例代码:

代码语言:txt
复制
var array1 = [1, 2, 3];
var array2 = [4, 5, 6];
var mergedArray = array1.concat(array2);

console.log(mergedArray);

输出结果为:

代码语言:txt
复制
[1, 2, 3, 4, 5, 6]

在这个示例中,我们定义了两个数组array1和array2,分别包含了一些数字。然后使用concat()方法将这两个数组合并为一个新的数组mergedArray。最后,通过console.log()方法打印出合并后的数组。

这种方法适用于任意长度的数组,可以同时合并多个数组。如果只有一个数组需要合并,也可以直接使用concat()方法。

javascript当中concat,join,slice用法

例 1.3(concat,join,slice) <html> <head> <meta http-equiv="content-type" content="text/html; charset=utf-8"/> <Script> /* 马克-to-win:qixy: Array is a dynamic array. - myArray = new Array(aLength) - myArray = new Array(anItem1, anItem2, anItem3, ...) */ var arr = new Array(1);//arr.length is 1,但是里面的东西是undefined, 所以这样写[undefined] /*虽然arr是个object, 但是里面的东西是undefined*/ document.write("typeof arr is "+typeof(arr)); var a = new Array(2, 6, 5, "a"); document.write("arr.length is "+arr.length+"a.length is "+a.length); var b = new Array(12, 14); arr[0] = "java"; arr[1] = "intel"; arr[2] = "microsoft"; /* Property/method value type: Array object JavaScript syntax: - myArray.concat(someValues, ...) The result of this method is a new array consisting of the original array, plus the concatenation. The values that are passed to the method are added to the end of the array. If arrays are passed, they are flattened and their individual elements added. The method returns an array consisting of the original Array plus the concatenated values. If Array1 contains "AAA", "BBB", "CCC" and Array2 contains "000", "111", "222", then the method call Array1.concat(Array2) will return an array with all the elements in a single collection. The original arrays will be untouched. */ document.write("arr.toString() is " + arr.toString() + "
"); //与无参join()方法等同 var arrconcat=arr.concat(a, b); document.write("arr.concat(a,b) is " + arrconcat + "
"); /*Array.join() (Method) Concatenate array elements to make a string. Property/method value type: String primitive JavaScript syntax: - myArray.join(aSeparator) Argument list: aSeparator A string to place between array elements as the array is concatenated to form a string. //无参join()方法默认是用逗号连接 */ document.write("arr.join() is " + arr.join
