1.jquery的JSON字符串处理 var pwdlevel_val = "{"minLength":1,"maxLength":20,"lowercase":false,"uppercase":false,"number":false,"special":false,"limitday":"","maximum":
public static void main(String[] a) { String wpp = "select 1, ${mark} '``this is, `/message22` special mark`\" this is ${mark1} special mark\"' `/message` ${mark} "; String pp = "((?=([^\\\"]*\\\"[^\\\"]*\\\")*
一.单引号与双引号区别 1." "双引号里面的字段会经过编译器解释,然后再当作HTML代码输出. 2.' '单引号里面的不进行解释,直接输出. 从字面意思上就可以看出,单引号比双引号要快了. 例1: $abc=’my name is tome’; echo $abc //结果是:my name is tom echo ‘$abc’ //结果是:$abc echo “$abc” //结果是:my name is tom 参考:http://www.cnblogs.com/youxin/a
