过滤特殊字符

就是正则写的有问题埃 function illegalChar(str) { var pattern=/[`~!@#\$%\^\&\*\(\)_\+\?:"\{\},\.\\\/;'\[\]]/im; if(pattern.test(str)){ return false; } return true; } alert(illegalChar("123?")); 应该就这样啊

1、jQuery使用正则匹配替换特殊字符 function RegeMatch(){ var pattern = new RegExp("[~'!@#$%^&*()-+_=:]"); if($("#name").val() != "" && $("#name").val() != null){ if(pattern.test($("#name").val())){ alert("非法字符!"); $("#name"...

过滤非法字符: /** * 替换xml特殊字符, * 过滤非法字符 HJX * @param s * @return */ public static String format(String s){ String reg = "[//x00-//x08//x0b-//x0c//x0e-//x1f]";//过滤掉非法字符 if ( s == null ) return ""; else{ s=s....

keyword=keyword.replace(/[\*\/]/g,"")

先把文本读到内存 假设读到缓冲区buf中 char *buf; //存放原始数据int len = strlen(buf); //计算长度char *data = new char[len]; //存放过滤后的内容int pos = 0;memset(data, 0, sizeof(char) * len);char *p = buf;while (*p){ char &c = *p...

把所有的特殊符号罗列出来即可。//javascript版本str = str.replace(/[·~!@#$%\^&*()\-_=+{}\[\]\\|:;'",./?]+/g, '')

String s = "sf9897&^%fdferf"; s = s.replaceAll("[^0-9a-zA-Z]",""); System.out.print(s);

function containSpecial( s ) { var containSpecial = RegExp(/[(\ )(\~)(\!)(\@)(\#) (\$)(\%)(\^)(\&)(\*)(\()(\))(\-)(\_)(\+)(\=) (\[)(\])(\{)(\})(\|)(\\)(\;)(\:)(\')(\")(\,)(\.)(\/) (\)(\?)(\)]+/); return ( containSpecial.test(s)...

按CTRL+Z输入 #include int main() { char a[100],ch; int i=0,j; while((ch=getchar())!=EOF) if((ch>='0'&&ch='A'&&ch

String str = "*(^YUIGHUGU^^&*()*6哈哈89324328uewh~!@#$%^&*()_+,./?;':[]\\{}|-=";//要过滤的字符串 str = str.replaceAll("[\\pP|~|$|^||\\||\\+|=]*", ""); System.out.println(str); 输出结果:YUIGHUGU6哈哈89324328uewh
