jQuery Create Array From String

Easy to convert strings into arrays with simple jQuery code snippets. Use jQuery's split() method (similar to PHP's explode() method) to split the words in a string into an array.

Sample code:

var numbersString = "1,2,3,4,5,6";
var numbersArray = numbersString.split(',');

You can then iterate through the values ​​in the array like this:

$.each(numbersArray, function(index, value) { 
  alert(index + ': ' + value);
});

You can also reconcatenate array elements into strings:

var numbersArray = new Array("1", "2", "3", "4", "5", "6");
var numbersString = numbersArray.join(',');
alert(numbersString); 
// 弹出 1,2,3,4,5,6

Remember to put your jQuery code inside the document ready function. For more information, please refer to four different jQuery document ready examples.

jQuery String to Array FAQ (FAQ)

How to convert a string to an array using jQuery?

Converting strings to arrays in jQuery is very simple. You can use the split() method of JavaScript. This method splits the string into a substring array based on the specified splitter. Example:

var str = "Hello World";  
var arr = str.split(" ");  

In this example, the "Hello World" string is split into an array containing two elements: "Hello" and "World". The space character (" ") is used as a separator.

How to convert a string to an array without using a delimiter?

Yes, you can convert strings to arrays without specifying delimiters. In this case, each character in the string will become a single element in the array. The method is as follows:

var str = "Hello";  
var arr = str.split("");  

In this example, the "Hello" string is split into an array of five elements: "H", "e", "l", "l", and "o".

How to convert comma separated strings into arrays?

To convert a comma-separated string into an array, you can use the split() method and use a comma (",") as the separator. Example:

var str = "apple,banana,cherry";  
var arr = str.split(",");  

In this example, the "apple,banana,cherry" string is split into an array containing three elements: "apple", "banana" and "cherry".

Can jQuery be used to convert strings into arrays?

jQuery is a powerful JavaScript library that simplifies HTML document traversal, event processing, animation, and Ajax interaction. However, it does not provide a dedicated method to convert strings into arrays. You can use JavaScript's split() method for this purpose.

How to concatenate array elements into strings?

You can use the join() method of JavaScript to combine array elements into a string. This method creates a new string by concatenating all elements of the array, separated by commas or specified splitter strings. Example:

var arr = ["Hello", "World"];  
var str = arr.join(" ");  

In this example, the array ["Hello", "World"] is concatenated into the string "Hello World". The space character (" ") is used as a separator.

How to convert a string to an array of integers?

Yes, you can convert strings to arrays of integers. However, you need to convert each string element into an integer using JavaScript's map() method. Example:

var numbersString = "1,2,3,4,5,6";
var numbersArray = numbersString.split(',');

In this example, the "1,2,3" string is split into an array of integers: [1, 2, 3].

How to convert a string to a multidimensional array?

Converting a string to a multidimensional array involves splitting the string into substrings, and then splitting each substring into an array. Example:

$.each(numbersArray, function(index, value) { 
  alert(index + ': ' + value);
});

In this example, the "1-2-3,4-5-6,7-8-9" string is split into a multi-dimensional array: [[1, 2, 3], [4, 5, 6], [7, 8, 9]].

How to convert a string to an array of objects?

Yes, you can convert strings to an array of objects. However, this requires a more complex process. Example:

var numbersArray = new Array("1", "2", "3", "4", "5", "6");
var numbersString = numbersArray.join(',');
alert(numbersString); 
// 弹出 1,2,3,4,5,6

In this example, the "name:John,age:30;name:Jane,age:25" string is divided into an array of objects: [{name: "John", age: "30"}, {name: "Jane", age: "25"}].

How to convert a string to an array using a regular expression?

You can use regular expressions as delimiters in the split() method. This allows you to split strings into arrays based on complex patterns. Example:

var str = "Hello World";  
var arr = str.split(" ");  

In this example, the "apple banana-cherry" string is split into an array of three elements: "apple", "banana" and "cherry". Regular expression /[s-] / Match one or more spaces or hyphen characters.

How to convert strings to arrays in reverse order?

Yes, you can convert strings into arrays in reverse order. You can use the split() method to convert the string to an array, and then use the reverse() method to reverse the order of the elements. Example:

var str = "Hello";  
var arr = str.split("");  

In this example, the "Hello World" string is split into an array containing two elements: "World" and "Hello".
