The example in this article describes the usage of javascript text template. Share it with everyone for your reference. The details are as follows:
This is a small function I wrote based on the Prism.js algorithm. There is nothing much to say. As a programmer, you should understand it in seconds after looking at the example.
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("");
}
}
How to use:
var str = new StringTemplate().format("你好%{userName }, 欢迎再次登陆%{systemName}",{userName: "小明", systemName: "jb51"});
//str="你好小明, 欢迎再次登陆jb51";
I hope this article will be helpful to everyone’s JavaScript programming design.
