Давайте разберемся с методами: slice( ), splice( ) и split( ) в javascript

Vertical Mode

Split.js also work in vertical mode. Just add direction vertical to the option.

Split(, {
    gutterSize: 5,
    sizes: ,
    minSize: ,
    direction: "vertical"
});

Then adjust your page layout accordingly.  Since I used flex layout in this tutorial, we’ll just change the flex direction to column mode. Then remove the gutter height setting and change the cursor direction to vertical double arrows.

.content {
  display: flex;
  flex-direction: column;
}
.gutter {
  cursor: s-resize;
  background: red;
}

With split.js you can now easily create amazing effect for your website. Here is the example using just split.js and CSS fixed background. (Source code at the end of this post)

Описание

Параметр является индексом символа. Индекс первого символа равен 0, а последнего символа — на один меньше длины строки. Метод начинает извлекать символы начиная с позиции и собирая символов (если он не достигнет раньше конца строки, в этом случае будет возвращено меньшее количество символов).

Если параметр является положительным и он больше, либо равен длине строки, метод вернёт пустую строку.

Если параметр является отрицательным, метод использует его как индекс символа, начиная с конца строки. Если параметр отрицателен и по модулю больше длины строки, метод будет использовать 0 в качестве начального индекса

Обратите внимание: описанная обработка отрицательных значений аргумента не поддерживается JScript от Microsoft

Если параметр равен нулю или отрицателен, метод вернёт пустую строку. Если параметр опущен, метод извлечёт все символы до конца строки.

String Primitives and String Objects

First, we will clarify the two types of strings. JavaScript differentiates between the string primitive, an immutable datatype, and the object.

In order to test the difference between the two, we will initialize a string primitive and a string object.

We can use the operator to determine the type of a value. In the first example, we simply assigned a string to a variable.

In the second example, we used to create a string object and assign it to a variable.

Most of the time you will be creating string primitives. JavaScript is able to access and utilize the built-in properties and methods of the object wrapper without actually changing the string primitive you’ve created into an object.

While this concept is a bit challenging at first, you should be aware of the distinction between primitive and object. Essentially, there are methods and properties available to all strings, and in the background JavaScript will perform a conversion to object and back to primitive every time a method or property is called.

Метод slice ()

slice () извлекает часть строки и возвращает извлеченную часть в новой строке.

Метод принимает 2 параметра: начальный индекс (положение) и Конечный индекс (позиция).

Этот пример нарезает часть строки из позиции 7 в положение 13:

var str = «Apple, Banana, Kiwi»;
var res = str.slice(7, 13);

The result of res will be:

Banana

Если параметр имеет отрицательное значение, позиция учитывается от конца строки.

Этот пример нарезает часть строки из позиции-12 в положение-6:

var str = «Apple, Banana, Kiwi»;
var res = str.slice(-12, -6);

The result of res will be:

Banana

Если опустить второй параметр, метод выполнит срез оставшейся части строки:

var res = str.slice(7);

или, считая с конца:

Usage

To split a tag or tags, run .

The Split Text initialisation function will accept a single or array of any of the following:

• JS elements
• jQuery elements
• selectors

will return a SplitText Object.

The Split text object has properties lines, words and chars which contain arrays of lines, words and chars respectively.

The Split text object also has a method revert() that will undo the changes that were made.

The SplitText function takes a second, optional object parameter. This can include additional attributes that change the functionality of the program.

Currently, Split Text supports the attributes type, charsClass, linesChars and wordsClass.

Type is a comma separated list list of the type of split to be carried out. The options are any combination of lines, words and chars. Note that chars cannot be used by itself at the moment without causing spacing problems. This should be fixed in a future version.

The three class elements will add a class to each of the split elements.

Two adjacent plus symbols in the class will be replaced by position of that split element. For example, would produce the line elements

<div class="line1">...</div>
<div class="line2">...</div>
<div class="line3">...</div>

Two adjacent asterisks symbols in the charClass will be replaced by the character and the next character. For example the word split with the charClass would produce the character elements

<div class="he">h</div>
<div class="el">e</div>
<div class="ll">l</div>
<div class="lo">l</div>
<div>o</div>

This makes it very easy to adjust the spacing between letters for advanced typography. If, for example, you wanted to change the spacing between the letters c and d, you would use the CSS

.cd{
   letter-spacing:-0.1em;
}

# Plugins

Plugins are the heart of Splitting, each performing a specific split on the targeted element(s). Some plugins have dependencies that will automatically run when called. For example will automatically split by to prevent issues with text wrapping.

Each plugin should containing the split elements. Some plugins have you can pass directly in the main options object for specific uses.

words

The plugin splits an element’s text into separate words, wrapping each in a populated with CSS variables and data attributes.

Usage

chars

Dependency:

The plugin splits an element’s text into separate characters. Before it can run, it splits by to prevent issues with text wrapping. is the default plugin if no other plugin is specified.

Passing causes the space between words to be counted toward the character index, though whitespace is collapsed while splitting so that there won’t be more than one space character between words.

lines

Dependency:

The plugin splits an element into separate words and then groups them by the line. It automatically runs the plugin.

Usage

items

The plugin indexes existing elements. It applies an to each matching element and to the target. If is not specified, the direct element children will be selected.

Usage

grid

Dependency: ,

The plugin detects the cols and rows of a layout by comparing the distance from the edges of the container. Plainly speaking, it assigns each selected element a row and column index. It automatically runs the and plugins.

Usage

The plugin detects the cols of a layout by comparing the distance from the left of the container.

Usage

The plugin detects the rows of a layout by comparing the distance from the top of the container.

Usage

cells

The plugin generates s based on the number of rows and columns provided. This plugin is perfect for splitting an picture with the option, which applies an image as a to the . Set a specific image with or use detect the first in the container for use.

Usage

Make Your Own!

Splitting is easily expandable to create your own splits. See the API for for more details. Be sure to share your plugins and demos with #splittingjs!

Accessing Characters

We’re going to demonstrate how to access characters and indices with the string.

Using square bracket notation, we can access any character in the string.

We can also use the method to return the character using the index number as a parameter.

Alternatively, we can use to return the index number by the first instance of a character.

Although “o” appears twice in the string, will get the first instance.

is used to find the last instance.

For both of these methods, you can also search for multiple characters in the string. It will return the index number of the first character in the instance.

The method, on the other hand, returns the characters between two index numbers. The first parameter will be the starting index number, and the second parameter will be the index number where it should end.

Note that is , but is not part of the returned output. will return what is between, but not including, the last parameter.

If a second parameter is not included, will return everything from the parameter to the end of the string.

To summarize, and will help return string values based on index numbers, and and will do the opposite, returning index numbers based on the provided string characters.
