This article mainly explains "how to convert an array into a string by JavaScript". Interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "JavaScript how to convert an array into a string".
The power of JavaScript arrays is hidden in array methods.
Convert an array to a string
The JavaScript method toString () converts an array to a comma-delimited string of array values.
Example
Var fruits = ["Banana", "Orange", "Apple", "Mango"]
Document.getElementById ("demo"). InnerHTML = fruits.toString ()
Result
Banana,Orange,Apple,Mango
The join () method can also combine all array elements into a single string.
It behaves like toString (), but you can also specify the delimiter:
Example
Var fruits = ["Banana", "Orange", "Apple", "Mango"]
Document.getElementById ("demo"). InnerHTML = fruits.join ("*")
Result
Banana * Orange * Apple * Mango
Popping and Pushing
When working with arrays, it is easy to delete elements and add new elements.
Popping and Pushing refer to:
Pops an item from an array or pushes it into an array.
Popping
The pop () method removes the last element from the array:
Example
Var fruits = ["Banana", "Orange", "Apple", "Mango"]
Fruits.pop (); / / remove the last element ("Mango") from fruits
The pop () method returns the value of "popped":
Example
Var fruits = ["Banana", "Orange", "Apple", "Mango"]
The value of var x = fruits.pop (); / / x is "Mango"
Pushing
The push () method (at the end of the array) adds a new element to the array:
Example
Var fruits = ["Banana", "Orange", "Apple", "Mango"]
Fruits.push ("Kiwi"); / / add a new element to fruits
The push () method returns the length of the new array:
Example
Var fruits = ["Banana", "Orange", "Apple", "Mango"]
Var x = fruits.push ("Kiwi"); the value of / / x is 5
