Example of javascript Text Template usage and javascript example

This document describes how to use a javascript Text Template. Share it with you for your reference. The details are as follows:

This is a small function I wrote with reference to the Prism. js algorithm. There is nothing to say. As a programmer, I should understand the example in seconds.

String template engine class:

/*class*/StringTemplate = function (/* Optional {patt: RegExp, clPatt: RegExp}*/pattern) {  if (!!pattern) {    this.patt = pattern.patt;    this.clPatt = pattern.clPatt;  } else {    this.patt = /%\{\s*[\w\-]+\s*\}/g;    this.clPatt = /(^%\{\s*)|(\s*\}$)/g;  }  this.format = function(val, map) {    var ls = [];    var res;    var prevEnd = 0;    while ((res = this.patt.exec(val)) != null) {      var va = res[0];      var start = val.substr(prevEnd, res.index - prevEnd);      prevEnd = res.index + va.length;      ls.push(start);      var vac = va.replace(this.clPatt, "");      ls.push(map[vac]);    }    ls.push(val.substr(prevEnd, val.length));    return ls.join("");  }}

Usage:

Var str = new StringTemplate (). format ("Hello % {userName}, welcome to log on again % {systemName}", {userName: "James", systemName: "jb51 "}); // str = "Hello James, welcome to jb51 again ";

I hope this article will help you design javascript programs.
