Tips for Javascript String concatenation (recommended): javascript string

In Javascript, you will often encounter character strings, but it is troublesome to concatenate a character string that is too long.

If it is in a row, the readability is poor. If it is to wrap, an error is reported directly.

This section describes several Javascript String concatenation techniques.

String addition (+)

var items = '<li class="details">' +       '<span>Hello world</span>' +       '</li>'; 

Concatenate a string using a backslash

var items = '<li class="details">' \       '<span>Hello world</span>' \       '</li>'; 

Concatenate strings using Arrays

Convert the array into a string using the join method of the array.

var empList = ['<li class="details">', '<span>Hello world</span>','</li>'].join(""); 

You can encapsulate a StringBuffer Method Based on the array to complete String concatenation.

function StringBuffer(){   this.buffer = []; } StringBuffer.prototype = {   constructor: StringBuffer,   append: function(str){     this.buffer.push(str);     return this;   },   toString: function(){     return this.buffer.join('');   } }; 

ES6 template string

ES6 introduces a new literal syntax called template string.

Replace the original single quotation marks or double quotation marks with an anti-apostrophes.

Worker ('.warning'worker .html ('
Line breaks, indentation, and spaces in the string are all output to the new string.
