Split a string and convert it into an array of words.

JavaScript String split()

The split() method splits a string into an array of substrings.

The split() method returns the new array.

The split() method does not change the original string.

If (» «) is used as separator, the string is split between words.

Js string into an array of words

Solution 2: Use split string method: Solution 1: You can use Array.join() on the array to generate a regular expression, and then use this one with String.replace(). Solution 1: How about AS3’s String.split? Solution 2: Think I’ve cracked it, here is the function in full: Basically, it uses the ‘not a word’ condition but excludes apostrophes, is global and ignores case.

Saving words from text into an array

By using the split() method, it is used to split a string into an array of substrings, and returns the new array. Read more about it here.

var text="your text"; var punctRE = /[\u2000-\u206F\u2E00-\u2E7F\\'!"#$%&()*+,\-.\/:;?@\[\]^_`<|>~]/g; text.replace(punctRE, ''); // Strip all punctuation from the string. var myArray=text.split(" "); // Pass an empty space as a separator. 

How can I put the individual words of a string in a, I need to put the words of a text area into a JavaScript array. I’ve got it working right up to the crucial point. I’ve written a function to count the words, but that didn’t really help as I need to count the words by using array.length or whatever the property may be.

Create an array of words (Strings) from String

How about AS3’s String.split?

var text:String = "hello world"; var split:Array = text.split(" "); // this will give you ["hello", "world"] // then iterate and strip out any redundant punctuation like commas, colons and full stops 

Think I’ve cracked it, here is the function in full:

public static function getArrayFromString(str:String):Array < return str.split(/\W | ' | /gi); >

Basically, it uses the ‘not a word’ condition but excludes apostrophes, is global and ignores case. Thanks to everyone who pointed me in the right direction.

var myString:String = "hello world"; var reg:RegExp = /\W/i; var stringAsArray:Array = myString.replace(reg, "").split(" "); 

Create an array of words (Strings) from String, public static function getArrayFromString (str:String):Array < return str.split (/ [\W']+/gi); >Basically, you can add any characters that you want to be considered delimiters into the square brackets. Here’s how the pieces work: The brackets define a set of characters.

How to change a phrase string into an array of word string in angularjs

Process a string into words seperated with the use of array

You can use Array.join() on the array to generate a regular expression, and then use this one with String.replace(). In the next example I use the replacement function of replace, it provides more control to the replacement logic in some cases. But you can avoid it and go with @Barmar answer.

let arr = ["old", "great", "other", "long", "good", "last"]; var str = "oldgreatotherlonggoodlastfirstnewownlittle";let re = new RegExp(arr.join("|"), "g"); let out = str.replace(re, (m) => m + " "); console.log(out);

.as-console .as-console-wrapper

However, note that the previous approach only works nice on some particular situations, but for example, won’t work so nice for var str = «oldotherlonglastfirstnewgoodownlittlegreat»; . Then, a more generic approach would be:

let arr = ["old", "great", "other", "long", "good", "last"]; var str1 = "oldotherlonglastfirstnewgoodownlittlegreat"; var str2 = "oldgreatotherlonggoodlastfirstnewownlittle"const separateMatches = (str, arr) => < let re = new RegExp(arr.join("|"), "g"); let out = str.replace(re, (m) =>` $ `); return out.replace(/\s+/g, " ").trim(); >console.log(separateMatches(str1, arr)); console.log(separateMatches(str2, arr));

.as-console .as-console-wrapper

Turn the array into a regular expression, and add a space before each match.

var str = "oldgreatotherlonggoodlastfirstnewownlittle"; var newstr = str.replace(/old|great|other|long|good|last/g, " $&"); console.log(newstr); str = "greatotherlonggoodlastfirstnewownlittleold"; newstr = str.replace(/old|great|other|long|good|last/g, " $&"); console.log(newstr);

In the replacement string $& stands for whatever matched the regular expression.

If you are looking for a way to make a regex from your array, you could do something like this:

let words = ["old", "great", "other", "long", "good", "last"]; let reg = new RegExp(words.join("|"), "g") 

You can then use it with string.replace to achieve desirable effect

Use Regex in Javascript to return an array of words, They could be [b-xï], for instance (from «b» to «x» plus «ï»). String.prototype.match always returns an array or null if no match at all. Finally, the g regexp flag stands for «global match». It means, it will try to match the same pattern on subsequent string parts. By default (with no g flag), it will be satisfied …

JavaScript: Tips of the Day

arrow functions

const shape = < radius: 10, diameter() < return this.radius * 2; >, perimeter: () => 2 * Math.PI * this.radius, >; console.log(shape.diameter()); console.log(shape.perimeter());

Note that the value of diameter is a regular function, whereas the value of perimeter is an arrow function.

With arrow functions, the this keyword refers to its current surrounding scope, unlike regular functions! This means that when we call perimeter, it doesn’t refer to the shape object, but to its surrounding scope (window for example).

There is no value radius on that object, which returns undefined.
