On _javascript techniques of JavaScript string stitching

String concatenation is often encountered in JavaScript, but it can be cumbersome if the string to be spliced is too long.

If on one line, the readability is too bad, if the line is changed, the error will be directly.

Here are a few tips for a few javascript concatenation strings (mainly for strings that are too long).

1. String addition (+)

var emplist = ' <li data-view-section= ' details ' > ' + '
      <span>hello world</span> ' +
     ' </li > ';

2. Use the backslash to stitch the string

var emplist = ' <li data-view-section= ' details ' >\
      <span>hello world</span>\
    </li> ';

3. Using array concatenation string

Copy Code code as follows:

var emplist = [' <li data-view-section= ' details ' > ', ' <span>hello world</span> ', ' </li> '].join ( "");

Using the Join method of an array to turn an array into a string

function StringBuffer () {
  this.buffer = [];
}
Adds the newly added string to the array
StringBuffer.prototype.append = function (str) {
  this.buffer.push (str);
  return this;
};
Convert to string
StringBuffer.prototype.toString = function () {return
  This.buffer.join ("");
};
Use
var buffer = new StringBuffer ();
Buffer.append ("Hello");
Buffer.append (', World ');
Console.log (Buffer.tostring ());

Based on the array method, a class similar to StringBuffer in Java can be encapsulated to complete the concatenation of strings.
