- 字符串替换
function stringFormate(string) {
var params = [].slice.call(arguments,1);
console.log(params);
var regex = /\{(\d+)\}/g;
var str = string.replace(regex,function(){
index = arguments[1];
return params[index];
});
return str;
};
- 简单的模板引擎
var tmplateEngine = function(tpl,data){
var regex = /<%([^%>]+)?%>/g;
while (match = regex.exec(tpl)) {
tpl = tpl.replace(match[0],data[match[1]]);
};
return tpl;
};
var tpl = '<p>Hello,my name is <%name%>.I\'m <%age%> years old.</p>'
var data = {
name: 'michael',
age: 27
}
var string = tmplateEngine(tpl,data);
console.log(string); //<p>Hello,my name is michael.I'm 27 years old.</p>
