Ext.String 方法

1.Ext.String.htmlEncode(value);  编码字符串,对其中特殊字符进行转义

xt.String.htmlEncode("hello'world");    //"hello'world"

2.Ext.String.htmlDecode(value);  解码字符串,对其中的转义字符进行还原

Ext.String.htmlDecode("hello'world");    //"hello'world"

3.Ext.String.urlAppend(url,string)  追加内容到查询字符中,?相连

Ext.String.urlAppend("www.baidu.com","a=1");    //"www.baidu.com?a=1"

4.Ext.String.trim(string)  去掉字符串开头和结尾位置的空格

Ext.String.trim(" hello world ");    //"hello world"

5.Ext.String.capitalize(string)  首字母大写

Ext.String.capitalize("hello");    //"Hello"

6.Ext.String.ellipsis(value,length,word)  截断字符串并在结尾处添加省略号  value 原始字符串 length 保留长度 word 设置为true则试图保留完整单词

Ext.String.ellipsis("my name is shi",3,false);    //"..."
Ext.String.ellipsis("my name is shi",3,true);    //"..."
Ext.String.ellipsis("my name is shi",6,false);    //"my ..."
Ext.String.ellipsis("my name is shi",6,true);    //"my..."
Ext.String.ellipsis("my name is shi",8,false);    //"my na..."
Ext.String.ellipsis("my name is shi",8,true);    //"my..."

7.Ext.String.escapeRegex(string)  将原始字符串中的-.*+?^${}()[]\进行替换

Ext.String.escapeRegex("hello -.*+?^${}()[]");    //"hello \-\.\*\+\?\^\$\{\}\(\)\[\]"

8.Ext.String.toggle(string,value,other)  对比两个字符串是否相等,相等返回other,不相等返回value

Ext.String.toggle("abc","abc","相等");    //"相等"
Ext.String.toggle("abc","cba","相等");    //"cba"

9.Ext.String.leftPad(string,size,[character])  在字符串左边填充指定字符串

Ext.String.leftPad("12 3",5,"0000");    //"000012 3"

10.Ext.String.format(string,value1,value2)  定义带标记的字符串,并用传入的字符替换标记。 每个标记必须是唯一的,而且必须要像{0},{1}...{n}这样地自增长
