JavaScript 的 StringBuilder
今天用JS 写了一个 类似于 C# 中的 StringBuilder 类, 可以在Javascript 中调用.用于处理大量的字符串拼接等,使得代码易读,易于维护.
首先引入 StringBuilder.js
<script type="text/javascript" src="StringBuilder.js"></script>
然后便可以很方便的使用了:
基本用法:
var sb=new StringBuilder();
sb.Append("Hello");
sb.Append("World ！");
var Result=sb.ToString();
用法二:
代码
// sb.AppendFormat("{0}....{N}","a",...."N");
var sb2=new StringBuilder();
var a="西狐";
var b=21;
var c="男";
sb2.Append("welcome! ");
sb2.AppendFormat("我叫:{0},年龄:{1},性别:{2}",a,b,c);
var sb2=new StringBuilder();
var a="西狐";
var b=21;
var c="男";
sb2.Append("welcome! ");
sb2.AppendFormat("我叫:{0},年龄:{1},性别:{2}",a,b,c);
用法三:
代码
// sb.AppendFormat("{0}....{N}",Array);
var sb3=new StringBuilder();
//可与数组一一对应
var param=new Array();
param[0]="20";
param[1]="微风三级";
param[2]="东南风";
param[3]="阳光明媚";
param[4]=new Date().toLocaleDateString();
sb3.AppendFormat("今天：{4},温度：{0}，风力：{1}，风向：{2}，{3}",param);
var sb3=new StringBuilder();
//可与数组一一对应
var param=new Array();
param[0]="20";
param[1]="微风三级";
param[2]="东南风";
param[3]="阳光明媚";
param[4]=new Date().toLocaleDateString();
sb3.AppendFormat("今天：{4},温度：{0}，风力：{1}，风向：{2}，{3}",param);
